Cooking up a lean, not mean, strategy

The pursuit of perfection and efficiency shouldn’t come at the cost of your team’s well-being.

By John Hitch Editor-in-chief

I probably type the word efficiency and its various forms more than a hundred times a week. That’s 5,200 times a year, far more than I’ve ever used the `, or backtick, button. I should probably figure out how to swap that key to write “efficiency” instead of `. (What the hell is it even for?) That would save me something like 2,600 seconds a year, or 43 minutes a year.

That’s just one small change. Imagine if I cared to search out waste in everything I do: How many seconds, minutes, and hours could I save? How much more effective of a leader could I be?

These are the questions devotees to continuous improvement and lean principles constantly ask themselves. And I met a lot of them while writing about manufacturing in a previous life. They dogmatically adhere to Six Sigma, Kaizen, and Total Productive Maintenance (TPM). When I moved over to trucking, I found leaders here practice what lean preaches, usually in a more holistic way.

TPM, for example, is all about making equipment work reliably through a series of workflows and rules. Fleet folks just call that preventive maintenance. They follow the OE recommendations and industry best practices and learn from experience.

From what I’ve seen, that’s because most lean principles are common sense—and a survival instinct. For Marshall Sheldon, a journeyman mobile technician for MHC Kenworth in Macon, Georgia, his experience has taught him that parking his service truck too close to a downed semi on a dirt patch could get him stuck. Getting unstuck takes precious time he could use to take on a new job, so he stops farther away. But all his tools are there, so he puts all his wrenches on a big metal ring and takes the whole lot to avoid walking back and forth. His apprentices see how well that works and will repeat it when they get their own truck.

A big part of implementing lean is measuring data, and Sheldon could have tracked his steps on a smart watch and filled out a spreadsheet to see if the wrench ring was worth it, but lean is also all about simplifying things. In this case, measuring would be a waste of time.

But when he needs to teach his trainees about conserving fuel by not idling, those fuel expense spreadsheets would tell the story better.

Both strategies save time and are worth doing, of course, but you have to question how

“The

much time you should spend implementing a net-positive efficiency workflow or process. If one of your wily veteran techs has a faster or better way of doing things, like how they set up a diagnostic cart, do you need to form an action committee to see if all carts should look this way or just have that tech send an email with a few supporting images?

But if that same tech recommends a new way for all triage to be done, you should vet the results before deploying across multiple shops. Putting in new lean workflows without verifying consistency and repeatability can lead to unintended consequences.

For a great example where you can learn about lean leadership as well as be entertained, watch “The Bear,” a show with efficiency baked into its core. On the surface, this Hulu show is about a dysfunctional award-winning chef, Carmy Berzatto, who moves back to Chicago after a tragedy and tries to turn his family sandwich shop into a Michelin-starred restaurant. But at its heart, it’s all about continuous improvement and efficiency (coincidentally just like my feature on lean management on Pg. 18). It’s also about the perils of chasing perfection when greatness will do.

Carmy spends countless hours and money on expensive ingredients to create the perfect menu that will dazzle and impress, all while pantomiming a busy dinner rush in the under-construction kitchen, making sure each movement, like grabbing a plate, falls beneath a certain time threshold. When it doesn’t, he

tweaks the layout plan to shave a second off here or there.

It’s an exhausting way of life. Carmy’s forehead veins bust at the seams due to the stress, and when his employees don’t meet his unmeetable expectations, he freaks out, screams, and goes out back for a smoke, as one does in a restaurant. They in turn walk out, leaving the operation shorthanded.

But the young perfectionist is so crazy because he was taught by his mentor that “every second counts.” She had those words on her kitchen wall, and Carmy does, too. He lives by them obsessively, and as an emotionally immature manager, makes his crew miserable most times by trying to be the best. And as it turns out, the experienced chef’s whole “every second counts” mantra was about enjoying every moment of life, to stop and smell the flour, not to race a stopwatch to please some pretentious gourmand. Keep in mind ensuring superior customer satisfaction is the ultimate goal of lean—and any shop, restaurant, or business that wants to keep going should target that. But think about how you get to that destination. Does the continuous improvement initiative you’re planning make things more complicated? Does it take months of meetings that lower morale and productivity? Most importantly, does it make you a critical jerk who compulsively points out waste? If any of these are true, the leanest strategy is to accept not everything can be perfect or optimal. Seek to remove waste, but not at the cost of your team’s sanity.

Smooth operation The latest in suspension and steering

From improved air springs to lighter systems, here are the suspension from OEMs and aftermarket providers that are guiding the industry

By Gregg Wartgow

CHASSIS ]

ngines get all the attention—and certainly they pull their weight and then some—but it’s the tractors and trailers’ suspension system that carries the burden of everything above them, while also absorbing all the bumps and potholes below. And don’t forget about the steering systems, without which all that power generated by the engine might not go where the driver intends.

Maybe we overlook these systems because, aside from the steering wheel, you can’t readily see the components. But there are innovations and improvement happening all the time, so we caught up with some of the biggest names and newest players in suspension and steering systems for commercial vehicles to discuss how their latest products are providing fleets with what they need to improve driver performance, extend component longevity, and simplify maintenance.

suspension and steering updates industry in the right direction.

Suspensions

Hendrickson

The Haulmaax EX Truck rear-drive axle suspension system has undergone significant enhancements over the past year. The latest update achieved a weight reduction of 19 lbs., making it the lightest-weight vocational rear suspension system available, according to the company. Additionally, Hendrickson introduced taller saddle heights of up to 26”.

“The weight reductions were achieved through optimization of the saddle design by changing the materials as well as eliminating a stamping,” said Mark Williamson, manager of product marketing and tech services for truck commercial vehicle systems at Hendrickson. “We also redesigned the lower bolster and beam connection to have the same mounting hardware. This common hardware sizing can help improve the efficiency of technicians when they service the bolsters.”

Another recent update from Hendrickson is the expanded application coverage for the Primaax EX air suspension system. There is now a 12” ride height, plus disc brake availability featuring large-clamp-group 26,000-lb. capacity axles. Those changes enable additional severe-duty applications such as wrecker trucks, as well as operation in Ontario, Canada.

Another recent Hendrickson development, the Roadmaax Z rear-drive axle suspension, features the company’s Zero Maintenance Damping (ZMD) ride technology. “Integration of ZMD removed the requirement for shock absorbers, which provides a consistent ride over the life of the air spring,” Williamson said.

Looking out on the horizon, development is underway for the Liteflex Hybrid Composite Rear Spring for medium-duty applications.

“By combining composite technology with steel springs, rear suspension weights can be reduced by up to 75%,” Williamson said. “These benefits come without compromise, providing premium durability and corrosion resistance. Additionally, composite springs have a proven record of not sagging over time compared to steel springs, maintaining the desired ride height.”

ContiTech

» ContiTech’s Continentalbranded air springs resist abrasion, corrosion, and misalignment.

ContiTech, a subsidiary of Continental, is expanding its a ermarket air spring portfolio with both Continental- and Prime Ride-branded products to provide ﬂeets with OEM-level quality. Using advanced materials and manufacturing processes, these air springs enhance ride comfort, stability, vehicle handling, and load-carrying capacity in a range of applications, including heavy-duty trucks, vocational vehicles, and trailers. And by resisting abrasion, corrosion, and misalignment, they help prevent premature wear for longer service life.

ROI Cabmate has been around for ﬁve years now, but Link says it continues to gain favor in the marketplace. In fact, two prominent ﬂeets added it to their truck builds in 2024, along with another Link innovation, SmartValve. And speaking of SmartValve, Link is in the process of releasing a revised product factory option kit for a top medium-, heavy-, and severe-duty truck manufacturer. at said, both the ROI Cabmate and SmartValve products are designed for tractor-trailer applications.

e company says these two suspension innovations address several ﬂeet pain points, including driver wellness, reduced air compressor runtime and component wear, and more discharge for gravity-fed tanker trailers. Also, SmartValve helps reduce damage to truck drivelines and trailer landing gear. Each product connects to the CAN, o ering diagnostic capabilities.

Looking ahead, Link is now working on a modular air suspension family for single, tandem, and tridem applications.

SAF-Holland

When speciﬁed with its lightweight PSP7 disc brake wheel-end package, SAF-Holland says its CBXAN23 is the lightest ﬁ xed-frame suspension in the market.

“ e CBXAN23 is ideal for applications where extra pounds and payloads equate to greater ﬂeet proﬁts,” said Lance Gage, product manager for trailer axles and suspension systems, Americas.

» SAF-Holland’s

CBXAN23 fixed-frame suspension system is designed for lighter weight and easy axle alignment.

SAF-Holland

Tandem-axle tank trailers hauling fuel or other petroleum products is a good example.

e “A” in CBXAN23 stands for Aerobeam, which is the weight-optimized cast trailing arm with narrow pivot bushing (the “N”). Gage said those two components, together with a premium highstrength axle tube, result in a light suspension. When it comes to service, Gage said simplicity is the name of the game. “All of our suspensions feature SwingAlign, which is the fastest, easiest axle alignment system.”

Looking ahead, SAF-Holland is developing a big brother to the CBXAN23, the CBXAS30, which will also be a heavy-duty, yet lightweight, suspension. “ is is planned to be production-ready in 2026,” Gage said.

Suspension tools

Cummins Drivetrain and Braking Systems (formerly Meritor)

Designed primarily for Classes 7-8 vehicles and trailer applications, the GAFF EZ Mount Torque Arm line uses highly engineered polyurethane bushings to obtain the ﬂexibility and resistance to torsion required in each rod, according to the requirements of the application. Its function is to maintain the horizontal stability of the vehicle, limiting the axle alignment angles and axle angles when braking or accelerating, navigating curves, or with road and load variations.

“In a word, GAFF polyurethane is resilient,” said David Irvin, product manager for Cummins Drivetrain and Braking Systems, A ermarket. “ ese torque arms can hold up better to the environment than standard rubber. And with over 90 di erent formulations, GAFF polyurethane is designed to mimic the feel of OEM rubber while providing the durability of polyurethane.”

Additionally, by having a rotating pin in the bushing, there is no need to clock the bushing. Irvin said a technician can easily rotate the bushing to the proper clocking and install the torque arm. “ is also allows for eliminating duplicitous inventory since the rotational bushing can be rotated to the proper clocking,” Irvin added.

and resistance to torsion.

Gabriel

Ride Control, the maker of the Gabriel brand of shocks and struts, has developed a unique tool to help identify shocks that are worn past their useful life.

e Gabriel HD Shock Tester will work with any heavy-duty vehicle due to the heat generated when shocks are working properly. It could also function correctly when servicing medium-duty vehicles depending on the weight/mass, because there needs to be a noticeable di erence between the temperature of working shocks and worn-out shocks. at’s why this tool is never recommended for anything under Class 5.

To evaluate shock wear, a technician follows a simple three-step process, which happens to be printed on the side of the tester for handy reference. e ﬁ rst step is to drive the vehicle for at least 15 minutes, perhaps longer if the roads are smooth. Within ﬁve minutes of parking, use the tester to establish a reference temperature on the vehicle chassis frame. en check the temperature of the shock absorber body below the dust tube (see photo). Just be careful to avoid touching the shock because it may be really hot.

Step three is to analyze the readings. “All shock absorbers should be warmer than the chassis,” said Jennifer Cameron, director of marketing at Gabriel North America. “Suspect a failure in any shock absorber that is noticeably cooler than its mate on the other end of the axle.”

Steering

Cummins Drivetrain and Braking Systems

Kingpins are the crucial connector between the axle and steering knuckle. Meritor’s FastSet spiral bushing and ReadySet bi-metal bushing kingpin lines have been around for several years, but continue to evolve to meet the diverse needs of ﬂeets.

“FastSet now covers 95% of trucks on the road for more than 5,000 make/model/year truck applications,” said Sam Marco, senior manager for Cummins Drivetrain and Braking Systems, A ermarket. “ReadySet covers 90% for more than 4,500 applications, including those found in linehaul, vocational, city delivery, and bus.”

For kingpin replacement, these no-ream kits eliminate the need for reamers, presses, and the

pressing-in of bushings. Kingpin bushings do not need to be reamed after being installed into the steering knuckle because internal grease grooves create a secure positioning. Thus, the kits are easily installed by hand with applicable bushing drivers. Additionally, that internal groove allows 375% more grease than ream kits, which is beneficial in high-wear areas.

“These kits make the aftermarket installation and repair of front steering axles fast and easy,” Marco said. “The kits also allow for a vehicle to not be jacked up during routine maintenance, and allow for annual savings up to $3,500 in labor and grease.”

DTNA

With Freightliner’s Fifth Generation Cascadia, the Detroit Assurance suite of safety systems will come with new options and features. The new short- and long-range radars provide the capability to track more objects that may be in the path of the vehicle.

“Advanced safety features on vehicles running across the country can help fleets achieve their safety goals,” said Miranda Richardson, manager for on-highway product marketing at DTNA. “Additionally, the steering hardware required for these systems offers excellent driver comfort features by minimizing vibrations, providing maneuverability assistance, and offering steering assistance in the event of a tire blowout by counter-steering against the truck’s tendency to pull towards the blowout.”

ZF Group

» ZF’s Electrically Powered Hydraulic Steering can power a hydraulic steering system without the need for a mostly combustion enginedriven PTO. ZF

ZF has been developing torque overlay systems to enhance steering responsiveness and comfort since 2006. ReAX-C replaced the first iteration (ColumnDrive) in 2020, and has since been expanded to highway tractor applications including the Kenworth and Peterbilt brands. This also marks the first time OnTraX (ZF’s lane keep assist technology) is available for commercial vehicles in North America.

The gear-based version, ReAX-G, was recently released for production in Europe and Asia, and will soon be introduced in North America. The company says it’s a good base for autonomous commercial vehicles headed toward L4 autonomy.

Electrically Powered Hydraulic Steering (EPHS) is another recent introduction from ZF. It’s an electric motor-driven pump that powers a hydraulic steering system without the need for a mostly combustion engine-driven PTO. ZF says this technology can be found on electric vehicles from manufacturers such as Nikola, VDL, and Iveco.

EPHS is beneficial for addressing packaging limitations and fuel economy targets for tradi-

Steer-by-wire

An emerging technology for commercial vehicles in the U.S. is steer-by-wire. This advanced steering technology replaces traditional mechanical and hydraulic linkages with electronic controls. Driver inputs are digitally transmitted through sensors and actuators, which then control the steering system.

Steer-by-wire manufacturers say this solution results in a safer and more reliable driving experience, while also facilitating more suitable vehicle maneuverability. Manufacturers of this emerging technology include Bosch Mobility, Nexteer Automotive, ZF Group, and REE Automotive.

REE Automotive in particular has been garnering a lot of attention due to some of its solutions being geared toward fleet-type vehicles. In fact, the company recently hosted a ride-and-drive event for its P7-C electric truck at the NTEA Work Truck Week in March. The company says this truck is

the first U.S.-certified, fully by-wire (x-by-wire) vehicle, which includes steer-by-wire.

“We’ve taken steer-by-wire technology to the next level by integrating it into our innovative REEcorner technology,” said Peter Dow, vice president of engineering and UK managing director at REE Automotive. “This system consolidates all essential vehicle functions—steering, braking, suspension, powertrain, and control—into a compact, modular unit located at each wheel. Our REEcenter ECU manages the system.”

In the case of steering, the system electronically adjusts the angle of the wheels based on the driver’s input, all without the need for a physical steering column interaction. Additionally, because each REEcorner is controlled independently, the company says maintenance can be managed more efficiently. Also, the software-driven nature of the platform allows fleets to benefit from predictive

tional powertrains, but especially for providing hydraulic-assist steering to alternative-fuel vehicles that may not have a constant power take-off, like a constantly running ICE engine.

EPHS also provides some benefits to steering feel, because it decouples hydraulic flow from an engine’s speed and precisely controls flow rate based on needs. The steering effort-based flow control optimizes fuel economy by adjusting the pump speed to match steering needs, thereby reducing unnecessary engine load and minimizing heat losses from recirculating excess flow within the pump.

From a servicing standpoint, ReAX products

maintenance powered by real-time data.

Dow said the P7-C is a Class 5 chassis cab truck that is currently being tested by specific fleets in the U.S. Another x-by-wire truck model, the P7-S, is a stripped chassis that allows fleets to build vehicles for virtually any size, shape, or function. Dow said that model is currently being evaluated by U-Haul. “We also offer our technology as a white-labeled solution for OEMs who wish to integrate it into their own vehicles,” Dow added.

ZF is also developing full-electric steering technology for commercial applications. The company says its current EPS (electric power steering) solution is already a major step toward more electronically controlled steering and steer-by-wire. Plans also include sophisticated integration strategies where steering systems will interact seamlessly with other crucial vehicle systems, boosting efficiency and safety.

(gear and column) should require minimal maintenance over their lifetime, the company assures. Calibration may be required after road wheel alignment or wheel, tire, and axle end stop changes. Additionally, typical maintenance for the base column, pump, and steering gear should be followed.

EPHS does not require any additional maintenance different than a typical hydraulic pump. That said, additional care should be taken to protect electrical connections during service.

Keeping the lights

By Alex Keenan

[ ELECTRICAL ]

Tonhere’s a lot for ﬂeets to focus on as spring rolls around, from trade shows to prepping trucks for warmer weather, but they should be especially aware of the Commercial Vehicle Safety Alliance’s International Roadcheck. e 2025 safety inspection event is set to take place from May 13-15, which means technicians should pay special attention to the various elements that can earn ﬂeets out-of-service (OOS) violations. Lighting is always at the top of the list.

Over the past six years, lighting issues have been responsible for an average of 1,783 OOS violations on trucks in North America, an average share of total vehicle violations of 12.4% per year. is rate has put lighting among the top ﬁve issues for vehicles every year since 2019.

Lighting violations tend to persist for many reasons. One is how ﬂexible the deﬁnition of an “operable light” is, according to Al Anderson, VP of sales and marketing at lighting and harness manufacturer Peterson Manufacturing.

“ ere are as many di erent opinions about what is legal [in the eyes of] the inspectors,” Anderson said. While some might think having one LED lamp out is grounds

for a ticket, another might forego penalties as long as a certain number of diodes are lit on a lamp.

And lighting is an easy catch for inspectors—as they either work or they don’t— noted Kaleb Osborn, product design engineer at Optronics. Also, it’s an issue that can be hard for drivers to catch while on the road, especially if a light goes out on a 53’ trailer.

“Drivers typically only inspect trailer lights during pre- or post-trip checks,” said Matt Zidek, sales engineer for Grote Industries. “Unlike issues such as a stuck brake or a damaged tire, there’s no immediate feedback alerting the driver to a problem that might require attention during a trip.”

While smart trailer solutions and the increasing flow of telematics data and fault notifications from a truck to the shop are helping to address the problem, this still makes lighting maintenance critical for both fleet safety and regulatory compliance. To help, here’s some of the most common issues for vehicle lamps, why they happen, and the tools a technician needs to keep their fleet bright.

Good equipment is a bright idea

Having proper equipment is key to the troubleshooting tests a technician needs to do to diagnose a lighting issue. Luckily, multimeters and load testers are common tools in the shop.

“Your standard automotive multimeter [is great],” Diesel Laptops’ Scott Meek said. “As long as it has the capability to measure amperage through an external amperage clamp, and as long as it measures voltage and ground, you’re pretty good. Most of your standard meters that technicians would have access to would give the capability to measure voltage and amperage.”

Some options include Electronic Specialties’ LOADpro tool and Back Probe Kit, Mac Tools’ EM823 digital multimeter, and the CAT IV Digital Multimeter.

The LOADpro tool and kit includes LOADpro test leads, tip adapters, two types of probes, and two types of alligator clips, with the test leads able to work with almost any digital multimeter. Meanwhile, the CAT IV multimeter can measure up to 1,000V AC/DC voltage and 10A AC/DC current as well as resistance, diode, continuity, and mx-Pulse/duty cycle. The EM823 features a pulse width of 0.5 to 240.00 ms and can run diode and continuity tests as well, and also features some new features like Bluetooth and USB connectivity.

Corrosion

According to Anderson, corrosion is the numberone reason that lights fail on trucks today, especially due to water and de-icing chemicals entering lighting systems at the connector between the lamp and the wiring harness or through a cracked lens. These contaminants can then short out internal components on the circuit board, he warned.

Additionally, corrosion can physically stop electricity from traveling through the system by increasing resistance along the wire harness.

“Once inside, moisture can travel through the wire via capillary action, spreading corrosion throughout the system,” Zidek said.

Also, while de-icing chemicals are a problem during the colder months, the corrosion they cause isn’t the only issue winter brings for lights.

“Snow and ice accumulation on lamps—both on tractors and trailers— pose significant visibility risks,” Zidek continued. “While LED lamps are excellent for their durability and energy efficiency, their low heat output makes them less effective at melting ice or snow.”

Cold weather can also freeze the moisture that creeps into the housing, and ice can also make wires more brittle. This means maintenance teams for fleets that operate up north should be on the lookout for degraded arrays and, when feasible, preventatively replace them ahead of Roadcheck.

» While lamps themselves don’t exactly have preventative maintenance best practices to attend to, a visual inspection for any damage to lights during a service is advisable.

Vibration and physical damage

Corrosion isn’t the only culprit for electrical system woes. Given how delicate the wiring system can be and the punishment a heavy-duty truck takes on the road, physical damage can be a problem, too.

“Shorts in wiring can be caused by something as simple as a screw being placed in the trailer too far when it was being built, causing the screw to catch the harness, which eventually works its way to a wire, shorting it out,” noted Chuck Ralston, manager of the Truck Care Academy and mechanical services at Love’s Travel Stops.

This makes checking for what Anderson calls “clipping” or “routing” critical for technicians. This just means making sure no other sharp edges are going to rub against a truck’s wiring harness and potentially chafe a wire, especially at points where a wire goes across a cross member or through a channel. It’s also critical to ensure that a truck’s wire harness has convoluted tubing wherever it may wear against another component.

The connecting cord between the truck and trailer can be an issue, too, Anderson said. The connecting pins can wear out as the vehicle travels, causing them to lose their connection. Wear on both ends of that cord can sometimes even cause it to become disconnected entirely, cutting off power between the truck and trailer.

Power delivery and voltage

Beyond physical damage to a wiring harness that can put out lamps in a truck or trailer, power delivery issues from the truck can also cause problems, Optronics’ Osborn said.

“One thing that’s unique about the lighting and trailer world is you can’t control the power source because the power source comes from the truck,” Osborn explained. “So different trucks have different mechanisms for controlling the power output of the alternator for when they’re charging the battery, which then ultimately feeds the whole trailer system.”

According to Osborn, that power output from the truck should be around 13.75V. But depending on a truck’s alternator, voltage can spike up to double that and fall as low as 12V, especially if a driver is turning on or off equipment with a heavy power draw. A big enough voltage spike can even burst through a lamp’s resistor, damaging the light or making them work improperly, especially in older vehicles.

“If you’re running an older vehicle, you’ll have to put some inline resistors in there, because the vehicle won’t recognize the amp pull from the lights, so they’ll either flicker or they won’t come on at all,” said Michael Wittman, director of product management at Optronics.

And if one of those resistors cracks at a circuit board, that could also cause it to fail.

“If you’re going down the road behind a truck or a trailer, and you see a light with only part of the LEDs lit, it’s probably got a problem on the circuit board,” Peterson’s Anderson added.

Similar to the alternator issue, vehicle modules can also cause lamps to function improperly due to how they regulate the power that goes to a lamp.

“The problem with newer vehicles is a lot of [them] use cab control modules or body controllers, and those have internal integrated fuses that are virtual,” said Scott Meek, a former diesel technician and current director of diesel training for Diesel Laptops, a provider of diagnostic tools and training. These fuses provide internal circuit protection, but if a body controller finds a shorted wire is damaged, it can turn off that leg of a circuit, which can make lighting issues harder to identify.

“For an example, one weird lighting problem that I’ve had in the past is when you turn the headlight switch on, the box lights would come on for a second, and then they’d turn off,” Meek explained. Thinking this could be due to a virtual fuse, Meek tested the light’s voltage and amperage with a multimeter. He found that there was too much current draw to the lighting circuit, causing

The transition from incandescent bulbs to LEDs

Part of the reason that the power draw to a lamp can cause issues is due to how trucks have been transitioning from incandescent bulbs to light-emitting diodes (LEDs) over the past several years. The benefits of LEDs are many, as their solid state eliminates filament breakage from shock and vibration, said Paul Sniegocki, EVP of Engineering and CTO at Clarience Technologies.

LEDs also burn with less heat and create less amp draw on the electrical system, making them last longer overall.

According to Dustin Smith, VP of sales at Optronics, an LED light will last 50 times longer than an incandescent bulb.

“The light emitting part of [an LED] rarely has a failure,” said Al Anderson, VP of sales and marketing, Peterson. “Those are very, very reliable components.”

But while LEDs can produce a lot of benefits for a vehicle, if a controller is programmed to anticipate the power draw of an LED bulb and incandescent lamps are put in instead, this can cause issues. For example, Scott Meek, director of diesel training for Diesel Laptops, said if a driver experienced a bulb failure and put a few incandescent bulbs in their truck as a replacement, “now you’re drawing more current than that module allows,

the body control module to think there was too much current in the circuit and stopping current ﬂow to it, shutting the lights o .

The lighting diagnostic process

Now that we’ve discussed how lighting can go wrong, how can a tech approach all of this information in an orderly manner during troubleshooting? Starting with the basics helps, Meek said.

“ e ﬁ rst thing that any technician should real-

because it’s programmed for the wrong style of bulb, which means it’s not going to allow that much current to pass through it to power the incandescent.”

This can cause lights to only work for a moment when turned on or can speed up or slow down the cycle of a turn signal. Reprogramming a vehicle module to resolve the issue can vary depending on the manufacturer. Some might have different cab controller settings based on the bulbs used by each circuit, while others might only have settings for how much current a particular circuit can handle.

ly be doing when a vehicle comes into a shop for maintenance or repair is a visual inspection,” he said. “It’s not uncommon for a technician to get tunnel vision and say, ‘Okay, here’s my problem. I’m going to pull the truck in, I’m going to hook up my computer, I’m going to look for codes.’”

Instead, technicians should look for the simple answer ﬁ rst and check if a lighting system isn’t working due to physical damage, as if you damage one light, the entire circuit can be a ected, Meek explained. For instance, if a front right box light is hit by a branch and ripped from the trailer, it may pinch the voltage supply wire on its way.

“Now you’ve increased your current draw because now you have a short to ground, so your ﬂow and max available current ﬂow and everything on that circuit will be a ected because of that,” Meek noted.

Technicians should also make sure to use their visual inspections for a corrosion check, said Paul Sniegocki, EVP of engineering and CTO for Clarience Technologies. is means making sure that their connections don’t have a buildup of a white or green corrosive substance. is is also a great time to make sure a truck’s connections are in place and that everything’s plugged in correctly and there’s no rubbing, Osborn added.

But a visual inspection can also give clues for a technician’s later troubleshooting steps, too.

“If there is only one light out, the issue should be fairly close to the inoperative light,” Love’s Ralston added. “If multiple lights are out, the issue could be further away.” is could mean a technician will need to assess a trailer by sections and circuits to avoid getting overwhelmed.

With a visual inspection done, “common sense is the rule of the day,” said Peterson’s Anderson. is means starting at the source of a vehicle’s power: e truck itself. Make sure that the vehicle is starting well and charging the system properly.

» During the troubleshooting process for lights, it’s important to check the voltage at the light. Make sure not to pierce the wire coating for testing, as this leaves the wire open to water, ice, and chemicals.

Optronics International

“If the vehicle starts up just ﬁne, that’s generally an indication that we have su cient voltage, but we’d still want to verify that using a multimeter with electrical troubleshooting,” Meek noted. “You should always verify your voltage source, that it’s adequate.”

Checking that source voltage means testing “the only trustworthy ground on the vehicle, which is the battery negative post,” added Love’s Ralston.

Sniegocki also said that checking the circuit of a trailer’s nose box is a great place to start for troubleshooting, since it has seven-pin connectors that distribute power to standardized circuits.

“If all the lights are out on the circuit, that is a good indication that there’s an issue in that nose box, which in many cases is the factor for failure of electrical systems,” Sniegocki said.

If only one light is out, then it’s time to test the lamp that’s struggling, instead of immediately replacing it. If there’s no easy visual veriﬁcation that a light is damaged, then you can use a multimeter to check if there’s su cient voltage (at least 12 volts) and ground at the lamp itself. If the 12 volts are present at the connection and the light still isn’t working, the light is probably the issue. If the light works but it’s dim, there could be some resistance in the harness. But if a technician tries adding an external power or ground supply to the light and it works, there could be another issue.

“ at could be due to a damaged wire,” Meek said. “It could be a corroded connection. It could even be something as far as virtual fuses inside the control modules could be the cause of that.” Anderson added that there’s right and wrong ways to check a light for current, with the latter risking damaging the lamp and the entire electrical system. To check a light correctly, take the wiring harness out of the back of the lamp and check for current at the harness, he said, warning against sticking a test probe into the conductor or the coating of the wiring harness. is can leave a wound for corrosion to enter.

“If you stick a test light into the coating of the wiring harness, that hole’s there forever. It’s not like if you prick your ﬁ nger, your skin heals it up,” Anderson said. “ at will lead to corrosion and can go through a complete wiring harness system in a matter of hours if it’s powered up.”

A LEAN Pu ng back on the menu

t some point in your climb up the managerial ladder, you’ve probably come across a book on continuous improvement, or the Japanese equivalent “kaizen.” You may have even heard of Six Sigma, a strategy all about removing defects in processes, using data, and optimizing outcomes. Invented by Motorola engineer Bill Smith and popularized by General Electric decades ago for manufacturing, it codiﬁes tenets to help any leader. And for sure you’re familiar with Toyota vehicles’ storied reliability, though did you know that’s due to the Toyota Production System, which blends elements of Six Sigma and kaizen to reduce waste and boost quality?

Whether you have a deep or cursory knowledge of the above, what it all simply boils down to is being lean—removing excess, or trimming the fat, if you will. And that’s something all maintenance operations strive for, as maintenance is a thing you have to do, not want to do. If you want

to be excessive with customer service or employee incentives, or garishly outfit your trucks with chrome and color, knock yourself out. A er all, fat does add fl avor. But in the shop, it’s all about sustenance. What is the minimum amount of time and energy you can exert to get the best results? e return on investment must be quantifi able—and worth the e ort. And the way to fi nd that out is by integrating a lean mindset into all that you do.

To become a true master of lean, like a Six Sigma Black Belt, it takes years of reading and practice. But you could probably read this lean primer, or refresher, using examples and advice from bona fide e ciency aficionados and some who are just starting out, in about eight minutes. It should be a highly e cient use of your time (and if not, let us know and we’ll fi nd ways to improve ourselves!).

A thick slab of lean practices in the shop can be the best way to trim fatty ine ciencies and savor your team’s e orts.

Lean basics

By osmosis, you may already have the basic recipe for effective lean leadership in your head. Many oft-repeated axioms in business are derived from lean principles, such as “fail fast.”

David Julian, CTO and co-founder, Netradyne, a provider of AI dash cams for fleets, offered another, quoting legendary management expert Peter Drucker: “What gets measured gets improved.”

In other words, data is the foundation for continuous improvement.

And both adages are intertwined. To quantify what success looks like for a new initiative, you must set the demarcation line between winning and losing. That’s your benchmark. Ideally, it should be derived from data from both internal and external industry sources. (Plenty of maintenance providers, such as Penske and Fleet Advantage, offer benchmarking tools.)

Wherever you get it, just remember that without good data, you’re just guessing. Instead of a beautiful lean cut, you’ll wind up with mystery meat. Let’s say you review your shop numbers and you’ve chosen to improve technician efficiency, a KPI calculated by dividing a tech’s total hours by actual hours billed. You had a hunch it was down and confirmed so using your shop’s historical data. If you have more than one facility, compare this metric amongst them all. You can also check the average for your region by referring to industry reports, such as Fullbay’s State of Heavy-Duty Repair Report. In the latest installment, Fullbay found

the Southeast has a 117% tech efficiency rate in 2023, up 15 points from 2022. If your Savannah, Georgia-based shop has a rate of 80%, while the Augusta one is at 115%, that’s a sign you should focus on Savannah.

Those changes would likely also involve measuring and attempting to raise standard repair times. Maybe it’s one or two techs bringing this down, just like a faulty sensor can bring a whole system down. Using lean methodology, you can troubleshoot and find the root cause. If you need help, take a look at American Trucking Associations’ Technology & Maintenance Council Recommended Practice 1606, SRT Implementation Guidelines, and RP 538, Quality Shop Process Improvement. These can help you come up with general ways to raise efficiency and productivity.

“Bite-sized chunks”

To truly achieve lean operations, the KPIs you choose to raise should revolve around ways to make workflows and processes “faster, better, [and] cheaper,” Julian noted.

He learned this firsthand at the start of his career working on efficient communications with space probes at NASA’s Jet Propulsion Labs in the 1990s. JPL at the time was working on the Cassini probe that would journey to Saturn, as well as the Mars rover, and continuous improvement was vital as the scientists simulated the sun’s light output and Mars’ harsh terrain. While these multibillion-dollar projects were

going on, there was also a push to spread investments across a relatively cheaper array of $100 million ones, where they would risk more failure but also achieve faster results.

Using the tech efficiency example, you may want to select a handful of measurable ways to improve efficiency.

“Narrow it down and make it bitesized chunks,” Julian said. “What’s one or two things to work on? Over time, these small steps really add up.”

He likens this to how fleets can reduce accidents, a major expense on the logistics and maintenance sides, with dash cam deployments. Solutions like Netradyne’s detect unsafe driving and provide real-time in-cab coaching.

If a driver acts unsafely, the AI-enabled system immediately lets them know. The older model is waiting for someone at a call center to review a driver running a stop sign after the system identifies an event, alerting the safety manager, and then having them discuss with the driver several days later. That’s not lean.

“By the time the driver’s getting coaching, they don’t remember exactly what’s going on,” Julian said. The system has intricate rubrics and a scoring system of 0-1000 for tracking good and bad behaviors. For a driver with a 550, using the data, focusing on just a few areas, and quick coaching, Julian said they can jump up to 650, eventually hitting over 900.

By reducing steps and cutting out the middleman, “we’ve seen 30 to 50% reduction in accident rates or more from fleets across the board,” Julian said.

Learning to lean

A young shop in Northern California has stumbled upon basic lean principles to make the shop more organized and better serve customers.

By John Hitch

Not all shops have the time and resources to pull off a large initiative, but they can still be lean.

Nina Ceja, operations manager at United Fleet Maintenance (UFM) in Woodland, California, expected some comebacks in the first few months when the shop opened in 2021. Having to rework jobs is one of the most egregious anti-lean events a shop can have, for it doubles the work, possibly parts, and hurts the relationship with the customer. So Ceja said UFM now has the most senior tech review the junior techs’ work (they have four techs total) and has them explain their work step by step. It takes more time, Ceja admitted, but in the long run it prevents waste and protects the customer.

Though Ceja didn’t know it, UFM also naturally practices the 5S methodology of lean: Sort, Set in Order, Shine, Standardize, and Sustain. This really just means she makes sure the shop is clean and organized on a weekly basis.

A main reason for this is that the shop also services recreation vehicles, bringing in older customers.

“We have to keep the floors clean; we cannot have anybody trip over something,” she stressed.

Ceja also assigned the newest shop tech, right out of school, as the de facto lean enforcer.

“He is our main guy to ensure that everything is in its own place and understands why they’re in that place,” Ceja said. “It also feels like a good learning opportunity for him to get his hands on all the tools— by being the person

who’s responsible for making sure they stay in their spots.”

He’s also in charge of parts inventory, so he separates parts by various jobs, learning what brands are associated with which asset.

It’s sneakily brilliant, as the shop stays organized, allowing everyone to work more efficiently, while this one tech learns on the job.

Ceja, who admittedly doesn’t have a technical background, has found ways to optimize her own daily tasks by leveraging ChatGPT. UFM often submits bids to the California Department of General Services, and Ceja said creating the bids “used to take me a really long time because I would have to do the research myself for the parts and how long it would take.” If she couldn’t find the answer, she would ask a tech, taking time away from their productivity. Now she plugs questions into ChatGPT on parts’ price ranges and repair times, and gets answers in seconds. Ceja said she does fact check the answers, but the process narrows her search and keeps her from being overcharged or spending hours calling vendors. Overall, she can create the service estimates in one day.

UFM, which uses Fullbay’s shop management platform, has also digitized service reports to ensure clearer communication, and they use Airtable to automate scheduling.

“Sometimes the ball would get dropped,” Ceja said, “and we would have [a customer’s asset] for about a week, and then realize, ‘Hey, why is this unit still here?’”

The software now reminds techs to write their reports, using a template Ceja created to streamline writeups and make them less technical.

“They were handwritten and techs didn’t always know the right terms to use,” Ceja said. “We take that report and we put it into an AI agent, which will then turn out a service report that anybody can read.”

Lean layout

Henry Ford, the father of lean, is credited as being the ﬁ rst to truly implement waste-cutting methods like inventory control and standardizing workﬂows via the moving assembly line, all to ensure the Model-T could be made quickly, e ciently, and a ordably. ese are all highly pertinent things in the shop, a fact not lost on Ford’s maintenance side.

“At Ford, we honor Henry Ford’s lean legacy by embedding e ciency into our daily operations,” said Doug Danstrom, director of service performance at Ford Motor Company, noting that lean principles are used across Ford Pro’s Elite Commercial Service Centers, for everything from tasks like parts delivery to design questions such as shop layout.

Anyone who’s incurred several days of vehicle downtime due to a lagging part knows how much that delay hurts e ciency. And regarding shop layout, minimizing technician downtime in between working on vehicles ultimately maximizes time spent on service, Danstrom explained.

Some tactics Ford has employed to optimize the shop environment includes “expanded service bays, strategically placed equipment and well-deﬁ ned work zones that minimize unnecessary movement,” Danstrom said. “ is thoughtful arrangement not only maximizes speed and ﬂexibility but also enhances overall safety within the bay.”

But even with these strategies in place, the work is never truly done, as Ford practices “continuous evaluation and improvement to optimize workﬂows and reduce downtime,” Danstrom said.

Smarter parts strategy

at lean mentality started by Ford’s founder travels with former employees as well.

“It’s just in everyone’s DNA that works there—everyone’s looking at waste,” explained Harrison Wells, a mechanical engineer who helped design the Ford Windstar and Freestyle. Nowadays, he’s the vice president of professional services at the aptly named LeanDNA, a company that uses so ware to improve organizations’ supply chains by leveraging their proprietary enterprise resource planning system.

To get started, managers can come up with rules and prioritizations to “fi lter that noise in the ERP system and make [data] very actionable,” Wells said. e same mentality can also be applied to alerts from fleet and shop management platforms. A er all, wasting several minutes a day sorting through irrelevant notifications is akin to a diagnostic

tech having to si through dozens of superﬂuous fault codes.

Wells also advocates for injecting more analytics and data into your planning so ware, and having “a plan for every part” to exceed the traditional just-in-time parts model, which showed its ﬂaws during COVID with the numerous shortages that arose.

“People are putting a lot more thought into it,” Wells said. But to take advantage of this strategy, this means examining inventory service levels in relation to stocking. e percentage represents the likelihood you will be able to meet demand and avoid an out-of-stock situation that would ultimately lead to more vehicle downtime for your customers.

To help, LeanDNA uses a system based on the standard deviation of failures, and can recommend minimum stocking levels to hit a speciﬁc service level, Wells stated.

“Let’s say it’s a relatively expensive, steady part—you don’t want to strand somebody, so you might have a higher service level,” he explained, adding shops may want to keep critical parts with higher failure rates at 98%, while less critical, more reliable ones could be at 85%.

In general, now is a boom time for developing new lean practices, especially due to the implementation of large language models and analytics algorithms, all of which can provide shops with the information they need to improve their operations.

“It’s lean on steroids—you can perform the analysis so quickly,” Wells said of how advanced “AI” technology is pushing e ciency forward. “Basically, you can start pointing large language models at your ERP system and your data, and you can tease out information, and it’s surprisingly easy.” is allows you to “use data to pivot quickly,” he said.

at’s not as lean a phrase as “fail fast,” but as shops become more sophisticated with less room for wasted e orts, it’ll do.

But let’s close with one ﬁ nal morsel from the place where lean all started: Ford.

“Lean is a journey, not a destination,” Danstrom o ered. “Continuously seek improvement, even when performing well. e goal is to create a culture of continuous improvement, empowering everyone to enhance customer value. As Henry Ford showed, relentless eciency and innovation drive remarkable results.”

Rolling lean

Mobile mentor Marshall Sheldon discusses ways he gets his apprentices to think lean.

To Marshall Sheldon, journeyman mobile technician at MHC Kenworth in Macon, Georgia, working the mobile maintenance beat is like running a small independent shop, and that’s one of the first lessons he instills in his apprentices.

“After they get a really good grasp on fixing things, we focus on the business side of things, because every truck and every technician—to me—is its own little business.”

And while they break down the finances of running their truck, covering profit margins, and expenses, the subjects of efficiency and waste inevitably come up when they get to the fuel line item.

“We need to manage our fuel consumption, so we need to idle our trucks as little as possible,” the MHC brand ambassador said. “We don’t know what’s going to go on in the economy; we need to run as lean as possible.”

A quick way to upskill new apprentices, Sheldon said, was by having them each do mobile truck inspections every Friday. This lets them pick up on where tools go and what’s onboard each vehicle. When they run their own truck, all of that will be second nature and work will be done faster, he reasoned.

The mentor also makes the trainees who ride along with him write all the repair orders to build good habits.

“The more they do it, the more efficient they get at it,” he said. “My goal is always time to value, so when I get an apprentice, I want them to be profitable as quickly as possible,” he said.

By following Sheldon, who has more than 15 years of maintenance experience, many in leadership roles, the new techs also pick up on the savvy vet’s tricks to make work more efficient. For example, he’s learned that sometimes the truck needing repairs is in softer dirt, so he has to park up to 100 yards away. Sheldon will carry whole socket trays, and various-sized wrenches on a metal ring, to the work area so he does not have to waste time walking back and forth.

Another is rubbing penetrating oil on metal tools versus washing them with soap and water, which could lead to rusting.

He also sees the blunt truth when certain decisions must be made as a solid way to reduce turnover and subsequent onboarding expenses of their replacements.

WrenchWay reported in 2024 that the cost of hiring a new employee is $5,000, with it taking up to five months to get them to full productivity.

“We don’t have the time and the money to be worrying about replacing technicians when we could have just been honest,” Sheldon offered. “What I find is they take more ownership of the business. And this mindset builds loyalty.”

Sweating

the small stu

E ective ﬁlter changes can drive uptime and savings.

By Seth Skydel

You may live by the mantra “Don’t Sweat the Small Stu ,” but for keeping commercial vehicles operating e ciently, the little things matter. at’s especially true when it comes to oil, air, and even cabin ﬁ lters.

Employing best practices for ﬁ lter changeout intervals during routine maintenance keeps costs low and trucks out of the shop for unscheduled repairs. But determining the most e ective ﬁ lter change intervals is an exercise that needs to rely on experience, data, and technology.

Across the board, fleets and fi lter manufacturers note that OEM fi lter change recommendations are based on what engineers who developed the system had determined to be most e ective. eir requirements for fi lter changes also ensure warranty coverage.

Greg Treinen, vice president, on-highway market development at Daimler Truck North America, related that Detroit recommendations specify fi lter performance based on an optimum combination of fi lter micron rating and capacity, and mechanical requirements. e OEM also recommends fi lter maintenance intervals based on duty cycles that are grouped in four categories. is includes:

Ü E cient long-haul applications that average 7 miles per gallon or better

Ü Long-haul units with an average between 6 and 6.9 mpg and have minimal city stop-andgo operations

Ü Short-haul service for vehicles that travel 30,000 to 60,000 miles annually and average between 5.1 and 5.9 mpg

Ü Severe-service qualiﬁcations that apply to vehicles that travel up to 30,000 miles each year or average less than 5 mpg or that operate under severe conditions

Service data and even anecdotal evidence can also play key roles. Jay Stephenson, North American training supervisor for Fleetguard products at Atmus Filtration Technologies, for example, said it’s crucial to balance preventive maintenance schedules and service history. “Fleets should also check with drivers to gather feedback on any performance issues they may have noticed,” he added. “Drivers o en spot issues before they become major problems.”

Gabriel Blevins, training manager at Donaldson, said while service history can be beneﬁcial for optimizing uptime, sometimes maintenance schedules and practices are established and kept for long periods of time. “We recommend reviewing those practices periodically, as changes might have taken place with engine design and ﬁ ltration technology,” he said.

“Staying current is crucial to providing the best protection possible.”

In other cases, routine fi lter changes work best. For example, Donald Chilton, director of product management for WIX Filters, recommended changing cabin air fi lters at least once per year. “ ere is so much in the air that people don’t think about,” he advised. “A clean cabin fi lter allows you to have some defense against harmful contaminants.”

Cabin ﬁ lters, which are typically changed annually, are important for maintaining healthy working environments for drivers, Stephenson noted. As such, these ﬁ lters may need to be replaced more or less frequently, depending on the vehicle’s operating conditions.

Relying on data

Filter maintenance routines can be hard for ﬂeets to change, noted Chilton. “Most ﬂeets believe that if it’s working, don’t bother changing anything,” he said.

“But we live in a world of data that can help make informed decisions. ere is more available than ever, but some ﬂeets don’t use it to their advantage.”

For Jerry Greiner, VP of business operations, procurement & ﬂeet management at Transervice, oil sampling is one area where data can be helpful. “It can provide information about the condition of the oil at di erent mileage intervals,” he said. “ e data from oil samples will show you the correct change interval and help determine PM schedules. is data is especially important if you want to extend oil drains.”

Some ﬂeets stretch drain intervals by using oil analysis to detect early signs of damaging wear metals and identify contaminants, Chilton noted. “Oil analysis can alter routines,” he said, “but it requires a deep understanding of what the oil is doing and how much life is le as a result.”

Blevins advised having an analysis of new oil as a viscosity baseline. “ is is important when looking at used oil samples,” he said. “When oil viscosity has changed considerably, it is time to take action.”

For oil and oil fi lter changes, Stephenson said, using telematics data can enable fleets to fi netune their schedules or catch problems as they arise, such as coolant dilution or premature oil degradation. “For fleets with access to real-time telematics, performance-based adjustments may be possible, allowing for more precise scheduling of changes,” he added. “Data-driven maintenance schedules may also allow fleets to exceed standard service intervals when conditions are favorable.”

An onboard maintenance monitoring system in Detroit engines can compute optimal maintenance intervals based on the actual operating conditions, Treinen noted. e system utilizes powertrain data to determine speciﬁc maintenance intervals. “By honing maintenance recommendations based on engine and transmission load, the system reduces costs and downtime for service,” he said.

Real-time data can also come from technologies such as restriction indicators, Chilton related.

“Air fi lters should be changed once the restriction gauge starts to signal the need for replacement,” he said. “Most air fi lter housings are already config-

Transervice

ured with restriction gauges, and retrofit kits are available for those that don’t.”

There are two key benefits to consider when servicing by restriction, according to Blevins. The first is that it can be common to get two or three times the life of the filter versus servicing at every oil drain interval.

“The other benefit is that the air filter becomes more efficient over time,” Blevins explained. “Once it develops a dust cake layer on the media, that dust attracts other dust very effectively, so letting the air filter stay in longer actually provides better engine protection.”

While air filters should be replaced at the precise time to avoid contaminating the engine with airborne debris (if changed prematurely) or restricting airflow to the engine (if changed too late), an air restriction gauge can help, Stephenson pointed out. “The good news about restriction gauges is they’re inexpensive,” he added. “And new and improved solutions can provide more reliable readouts on air filter service life.

Taking a closer look

“Overall, if you’re experiencing downtime or component failures, it’s critical to look at the filtration system you’re using,” Stephenson continued. “If your filters are not reaching their expected service intervals, it’s worth considering a change in brand or performance level after having a conversation with your filter supplier to better understand the cause of the issue. A practical way to evaluate the impact of filtration is to test different filters to see if a new filter improves vehicle performance.”

When considering filter changes, Greiner noted, account for the environment the truck is operating in and its duty cycle. “Start with a pilot on a set number of trucks that have similar duty cycles to get comparable results,” he advised.

It’s important to note, according to Treinen, that finer filtration generally provides increased engine service life, but may require shorter filter change intervals. “When selecting your filter, be sure to choose one that meets SAE standards,” he said. “It is also important to note that capacity and efficiency ratings should not be the only criteria on which to judge filter performance. Other factors, including media strength, resistance to impulse failures, and burst strength often differ greatly between filter makes and should be considered in the filter selection process.”

No matter what brand you choose, Blevins said to start with premium OE grade filters. “If that baseline is met and problems arise, it’s important to determine what the problem is before changing,” he added. “Treat each situation with an investigative approach. If you are looking to change filtration away from OE recommendations, there are risks involved, and caution should be taken.”

“Changing brands is always more complex than it initially appears,” Chilton said. “If you are not happy with the results of your current filter, do your research and find the brand that works for you. Nothing beats good maintenance software and faithfully logging data. If you’re diligent, this is by far the best investment you can make.”

For Stephenson, the key to determining the

Understanding filter life

To help customers better determine their remaining air filter life, Fleetguard has introduced FleetguardFIT, an air restriction indicator that enables maintenance intervals to be determined based on real-world conditions. A direct replacement for spring-loaded mechanical restriction indicators, the new technology uses an algorithm that monitors restriction across the air filter and changes color from green to yellow to red based on the filter’s restriction, providing both a visual indication and an electrical signal of filter status.

At Geno’s Garage, a Ram Cummins Turbo Diesel and Ram 1500 EcoDiesel parts business in Cumming, Georgia, Brandon Parks, business and product development manager, immediately saw the value of FleetguardFIT. “Even though I was not having any problems, I removed and inspected my air filter, and I had never seen it look so bad,” he said. “But according to the FleetguardFIT restriction indicator, it still had life left so I realized I could extend the time between changes.”

Why filtration science matters

In 2022, noted Ismail Bagci, technical director at Fleetguard, a brand of Atmus Filtration Technologies, the result of an unanticipated shift in governmental policies, changing feedstocks, and geopolitical events that limited supplies of conventional ultra-low sulfur diesel (ULSD) was that fleets accelerated their use of a variety of biodiesel blends.

But the changes in biodiesel blends came with a consequence no one anticipated. Users of a new diesel engine, he noted, reported premature clogging of fuel filters that resulted in service intervals 30% to 50% shorter than expected.

The filters were caked with an unusually high amount of soft, gel-like deposits of an ultra-fine nature, Bagci explained further. Chemical analysis revealed the deposits were metal salt carboxylates that formed in the engine under the high temperatures and pressures of the high-pressure common rail (HPCR) fuel injection system. Then, uncombusted fuel—containing the newly formed carboxylates—was recirculated back through the fuel system.

While Fleetguard filters with nanofiber technology targeted and captured hard contaminants such as sand and dust, the company discovered that the filters lacked the capacity to hold the volume of soft organics created from the new biodiesel blends. After evaluating many different combinations of media, it was determined that adding a glass layer would hold the high volume of soft contaminants and still meet the OEM’s original service intervals.

Testing validated this approach, Bagci noted, and the redesigned filters provided seven times greater life and more than double the carboxylate removal efficiency compared to the original filter design.

optimal service schedule for a truck’s filters is to find the “Goldilocks Zone”—not changing parts too early or too late to maximize their lifespan and system protection as well as reduce unnecessary maintenance costs.

“Higher-quality filters, like many other components, usually offer longer service intervals and

can be worth it,” Stephenson said. “Saving a buck or two on filters could cost you more in the long run if it impacts vehicle performance and lifespan.”

Servicing CNG engines in the shop

Compressed natural gas engines aren’t that much different than their diesel counterparts, but servicing CNG vehicles as a whole is a completely different animal.

By Gregg Wartgow

» A lot goes into making a shop suitable for working on natural gas vehicles so it can become certified. Rush Truck Centers has made the necessary commitment.

why CNG has taken off as the natural gas of choice in the transportation industry. The “return to base” aspect of a fleet lends itself to on-site fueling, or at least more predictable local fueling.

“Fleets with optimal logistics are able to capitalize on CNG-powered vehicles today,” said Victor Cummings, VP of service operations for Rush Truck Centers, a large network of commercial vehicle dealerships with more than 150 locations in 23 states and Ontario, Canada.

Regardless of whether you’re talking CNG or LNG, the natural gas engine on a natural gas vehicle (NGV) is the same. Quite frankly, that engine isn’t all that different from a diesel engine. There are some important distinctions though, especially as you work backwards toward the fuel tanks (cylinders). And because of those distinctions, some significant changes need to be made in the shop in order to service NGVs.

How are natural gas engines different?

To answer that question, King said he first likes to look at what is similar to a diesel engine.

“Both have an engine block, oil pan, lube system, and cooling system,” King pointed out, adding that in many cases, part numbers are identical. “But when you get to the cylinder head, the design is specific to the fuel type. There are unique cooling passages on a natural gas engine to keep the head and spark plugs cool. Speaking of which, sparkplugs and ignition coils replace the diesel fuel injectors since natural gas is a spark-ignited fuel.”

Natural gas is a cleaner, cheaper fuel that can help fleets slash emissions and lower operating costs. And now, with last year’s introduction of Cummins’ 15L natural gas engine with power ratings up to 500 hp, the X15N, this domestically produced fuel is becoming a viable option for a wider range of fleets.

Natural gas has already gained widespread acceptance among refuse truck and transit bus fleets. There has also been solid adoption among vocational fleets that rely on 9L engines. “Now, for that second tier of Class 8 trucks that require at least 10L, we’re seeing the most interest from regional haul fleets,” said David King, product manager for natural and renewable gas engines at Cummins.

Reliable fueling is a big reason why. There are tens of thousands of public fueling stations across the country where tractor-trailers can fill up with diesel. On the other hand, according to data from the Alternative Fuels Data Center of the U.S. Department of Energy, there are only around 700 CNG (compressed natural gas) public fueling stations in the U.S. There are even fewer (50) LNG (liquid natural gas) stations, which is a big reason

A natural gas engine also has a similar ECM, although the software is unique. There is also a spark and fuel-injection control module. “That’s because fuel is no longer injected into the combustion chamber,” King pointed out. “Fuel is now injected into the intake manifold.”

Natural gas engines do not have diesel aftertreatment system components such as a DPF, hydrocarbon doser, SCR, or DEF.

“You still have an EGR with a CNG vehicle,” said Javier Gonzalez, service director for Rush Truck Centers’ Peterbilt dealerships. “You also have something known as a three-way catalyst that’s designed to lower carbon monoxide, VOCs, and NOx emissions coming out of the engine. It’s essentially three bricks made up of precious metals that are located in the exhaust pipe, kind of like a sophisticated catalytic converter you’d find on a gasoline vehicle.”

What do these differences mean with respect to engine maintenance?

First of all, technicians need to maintain spark plugs on a natural gas engine. Cummins has taken steps to make it more convenient by aligning that interval with an oil drain. “We’ve worked to extend the oil drain interval on our newest natural gas engine, the X15N, by 50% over the 12L version,” King said. “We’re getting closer to diesel-like drain intervals now.”

Cummins’ natural gas engines also require oils that meet specific requirements regarding low ash content and the ability to handle higher moisture. King said Cummins worked closely with Valvoline to develop CES 20092, an engine oil specification for spark-ignition natural gas engines that can also be used in diesel and gasoline engines. Valvoline’s Premium Blue engine oil meets that specification, as does Chevron’s Delo 600 ADF engine oil.

In the grand scheme of things, the engine itself is a minor piece of the shift required for fleets to begin using natural gas.

“The biggest thing is just ensuring that the frame layout and fuel system are tailored to the need and application of the vehicle,” said Kyle Kimball, director of marketing at Kenworth Truck Company. “You never want to take up frame space with excess fuel that may not be necessary for a specific duty cycle.”

A CNG-powered commercial vehicle could have anywhere from two to six CNG cylinders on board, mounted either behind the cab, on the side, or on the roof. Those cylinders, along with the fuel system in general, represent the biggest difference between natural gas and diesel—which includes how fleets must go about servicing NGVs.

Standards and inspections

There are inherent safety risks associated with CNG, largely stemming from the unusually high pressure at which the fuel is stored (3,600 psi) onboard the vehicle.

“On a CNG vehicle, you’re seeing high pressure throughout the fuel system, from the fuel-pressure regulator all the way back to the cylinders,” Gonzalez said. “There are a lot of components in between that need to be regularly inspected. That’s much different than a diesel vehicle where the only high pressure you’ll see is from the high-pressure fuel pump, the fuel rail, and down to the injectors.”

Annual inspections are a key element of running a CNG fleet. Inspections are required to ensure that all fuel system components are mechanically sound.

“There are multiple standards and regulations that a CNG servicing facility must abide by,” Gonzalez pointed out. “One is the Federal Motor Vehicle Safety Standards (FMVSS) from the National Highway Traffic Safety Administration (NHTSA). Any vehicle over 10,000 lbs. must go through a 12-month inspection that includes the fuel cylinders (tanks) themselves, along with the fuel lines and other components that make up the CNG fuel system.”

Gonzalez said his technicians are looking for things like fuel cylinder imperfections. Type 4 cylinders are becoming the most common, which consist of a composite fiber resin and have a 20-year life expectancy.

“We use a depth gauge to look for abrasions in the resin,” Gonzalez said. “There is a specification set by ANSI and the NFPA (National Fire Protection Association) that includes inspection requirements associated with nicks, gouges, and abrasions. You can’t just rely on eyesight. And if a label is ever missing from a cylinder and you can’t verify the manufacturer, it must be taken off the vehicle and decommissioned.”

Two reasons fleets switch to CNG

The decision for a fleet to begin operating CNGpowered trucks comes down to two things, according to David King, product manager for natural and renewable gas engines at Cummins.

1. SUSTAINABILITY

“Fleets with internal ESG goals, such as a low-carbon initiative, are drawn to natural gas,” King said. In some instances, a client pushes their freight carrier to begin utilizing low-carbon fuels.

Whatever the motivating factor, CNG (compressed natural gas) is a much “cleaner” alternative to diesel.

According to data presented by The Transport Project, combusting natural gas produces 27% fewer CO2 emissions than diesel on an energy-equivalent basis. Furthermore, modern natural gas engines often reduce NOx by 95% over current standards, and particulate matter (PM)

by 90%. Additionally, CNG in heavy-duty vehicles has 13-17% fewer greenhouse gas (GHG) emissions compared to diesel on a well-towheel basis. That well-towheel GHG footprint grows even smaller when a fleet is able to use renewable natural gas. RNG is made from gases captured from places like landfills, wastewater treatment plants, and even farms.

2. ECONOMICS

King said natural gas has generally been a lower, more stably priced fuel compared to diesel.

To King’s point, the most recent retail fuel price data published at the Alternative Fuels Data Center website shows that CNG was running about 10% (33 cents) cheaper per diesel gallon equivalent (DGE) in October 2024. Back in October 2023, the difference was 29% ($1.17).

Keep in mind that fuel econo -

The same type of thorough inspection must be performed anytime a CNG vehicle is involved in any type of accident, even the mildest of fender benders. It all comes down to CNG vehicle safety, which is why a service facility must be certified to work on NGVs.

Setting up the shop

Fire risk is a key hazard that must be mitigated in order for a shop to become NGV-certified.

“If you plan to service vehicles indoors, they must be serviced in conditioned bays,” Gonzalez explained. “As dictated by the NFPA, these bays must be equipped with methane detection systems, shatterproof lighting, and proper ventilation.”

Due to CNG being in a gaseous state, a shop cannot afford to have a spark, so technicians cannot use cordless battery-electric hand tools or electric lifts. “Our certified CNG technicians are using manual wrenches and air-actuated tools,” Gonzalez related. Speaking of “manual labor,” CNG engines can sometimes be more difficult to diagnose. Gonzalez said drivers

my is lower when combusting natural gas, simply due to the fact that natural gas has to be spark-ignited. How much fuel economy is lost depends on duty cycle and other factors. King said it could land anywhere from 5 to 20%. The Transport Project pinpoints it in the 7 to 12% range.

So how does all of this pencil out for a fleet?

As an example, let’s use a 10% loss in fuel economy, a fuel price difference of $1 per DGE, and a 50,000-mile driving range. A Class 8 CNG truck getting 6.3 mpg will spend 17% less on fuel than a diesel truck getting 7 mpg.

“Even with the higher upfront vehicle acquisition price for a CNG truck, the fleet will get payback on that investment over the last few years of the truck’s lifecycle,” King said. “And the more fuel that truck burns, the more the fleet saves.”

may sometimes complain about misfires or low power, but sometimes there is no fault code. Understanding the air/fuel mixture and overall flow of the fuel system is important. Sometimes the root cause of a power issue is something

really simple, like a malfunctioning fuel gauge that suggests there is CNG left in the cylinder when there really isn’t.

“A compression tester is a valuable tool when drivers have complaints like this,” Gonzalez said.

Another good specialty tool to have in the bay is a handheld methane detector. This helps a technician pinpoint leaks around the engine compartment or cylinder system.

As touched on earlier, on-site fueling can help local and regional fleets gain better control over their fuel supply. There’s a lot that goes into it, however.

Representatives from ANGI Energy Systems, a supplier of CNG refueling equipment and systems, said the first step is assessing site suitability. There needs to be adequate space, power supply, and access to a natural gas pipeline. There is also a lot of permitting and safety compliance measures that need to be taken. It’s crucial to budget carefully and take advantage of any potential grants or regulatory incentives that could help defray some of the upfront costs.

When switching to natural gas, there will be some upfront costs involved. Trucks cost more, shops typically require some upgrades, and technicians need special training to become certified. But there are also significant operational costs that can be avoided by running on CNG, making it worthwhile for a variety of light-, medium- and heavy-duty fleets.

Turning garbage into fuel: The case for RNG

One benefit of natural gas is the fact that it’s a domestically produced fuel. In the U.S., natural gas is produced from shale and other types of sedimentary rock formations through a process commonly known as fracking. While natural gas is a cleaner fuel that produces significantly fewer tailpipe emissions, there are some well-to-wheel emissions associated with the extraction, production, and distribution of this alternative fuel.

Renewable natural gas, on the other hand, doesn’t require the earth to be fractured to harvest the fuel. RNG captures gases emanating from places like landfills, wastewater treatment plants, and sometimes farms. That results in significantly fewer emissions from the production process, which helps lower the total carbon footprint even better than conventional natural gas does.

Companies like Nopetro Energy are helping bring RNG to the marketplace. RNG is piped into the same pipeline as conventional natural gas. The two can be mixed because they are chemically identical. For a fleet, that means they can run RNG through the same CNG engines and vehicles they already have.

“RNG not only brings environmental benefits, but also financial savings,” said Jorge Herrera, CEO of Nopetro Energy, a provider of alternative fuel solutions including RNG and LNG, hydrogen, and Nopetro E+ renewable electricity. “RNG is also a renewable fuel that’s helping cure a societal problem. Society is not going to stop producing waste. That waste will continue to accumulate in landfills. RNG helps cure that problem, while also turning that waste into a usable commodity for transportation in a way that’s scalable.”

Nopetro Energy has 15 production facilities across Florida. Those facilities capture the biogas (biomethane) escaping from landfills, etc., and clean and refine it so it’s indistinguishable from conventional natural gas. The company’s newest facility in Vero Beach is in partnership with the Indian River County Solid Waste Authority.

Renewable propane’s role in a cleaner future

Growing production and real-world adoption show propane’s potential for lower emissions.

» One of the newest production methods for renewable propane is from a cover crop called camelina.

As the transportation industry works toward a clean emissions future, new energy solutions are emerging to meet sustainability goals. One of the latest innovations is renewable propane, offering a cleaner alternative while maintaining the reliability and affordability that fleet owners depend on. With production expanding and availability increasing, renewable propane is making its way into operations across the country and proving to be a viable solution for fleet owners.

What is renewable propane?

Renewable propane is chemically identical to conventional propane but is produced from renewable feedstocks. It offers the same benefits as conventional propane—reliability, portability, and power—but with even lower emissions. It can be used in existing propane-powered vehicles and refueling infrastructure without modifications to equipment, providing a seamless transition for fleet owners currently operating propane autogas vehicles.

How it’s produced

Renewable propane is made from a variety of renewable feedstocks like vegetable oil, animal fats, or used cooking oil. One of the newer feedstocks is the oil contained in camelina seeds. Because camelina is not a food crop, its production is highly scalable, allowing for production to ramp up quickly as more farmers adopt camelina as a cover crop.

Beyond traditional feedstocks, researchers are exploring new ways to produce renewable propane. Recent studies show the energy source can be made by breaking down plastics, such as polyethylene and polypropylene, and by converting captured carbon dioxide into renewable propane. These advancements reduce waste while increasing the availability of low-carbon energy options for fleets.

How clean is renewable propane?

Energy sources are measured by their carbon intensity scores—or how much carbon is produced by the energy source. While the carbon intensity of renewable propane depends on the feedstock, it’s lower than many other fuels. Renewable propane derived from used cooking oil has a carbon intensity score of just 20.5, compared with 79 for conventional propane and 130 for the average U.S. electricity grid. Renewable propane made from camelina has one of the lowest carbon intensities, with studies showing it can reduce greenhouse gas emissions by up to 60%.

As with conventional propane, renewable propane also provides significantly reduced

nitrogen oxide emissions and virtually no particulate matter, with an even lower carbon intensity for fleet owners.

Current availability

Currently, more than 4.5 million gallons of renewable propane are produced every year. While sometimes used by itself as a vehicle fuel, renewable propane can also be added to innovative blends to provide more fleets an opportunity to reap the low-carbon benefits of the energy source. Within the next few years, 100 million gallons of renewable propane will likely be available with a total potential of 300 million gallons in the next decade. In fact, by 2050, renewable propane could meet half the world’s demand for non-chemical propane, according to the World LP Gas Association. The push for cleaner liquid fuels such as sustainable aviation fuel and renewable diesel fuel will lead to an increase in renewable propane production. Many businesses across the United States are now offering renewable propane to fleet owners. In 2023, the Pride Travel Center became the first facility in Connecticut to offer renewable propane alongside other alternative fuels. NGL Supply Wholesale in Massachusetts is providing renewable propane at its Springfield terminal, expanding access in the Northeast. On the West Coast, U-Haul locations in California are offering the fuel as part of the company’s sustainability initiatives.

Fleet adoption

Thanks to increased production, fleets across the country are using renewable propane. In Raleigh, North Carolina, the city transitioned a portion of its fleet to run on renewable propane with a goal to reduce citywide greenhouse gas emissions by 80% by 2050. Of the city’s 4,600 vehicles, 85% run on some type of alternative energy, and renewable propane is playing a pivotal role in those emissions reductions. In Petersburg, Virginia, 49 police and shuttle vehicles operate on renewable propane as part of the city’s sustainability efforts, demonstrating how municipalities can incorporate low-carbon energy into their operations.

School districts from coast to coast are also adopting renewable propane. Beaverton School District in Oregon, for example, has integrated renewable propane into 66 of its propane-powered Type C buses that save the district more than $200,000 in fuel costs alone compared with diesel. Meanwhile, at Bonny Eagle School District, which operates the largest public school bus fleet in Maine, nearly 80% of the fleet now runs on renewable propane. As fleet owners navigate the evolution to lower-carbon energy sources, renewable propane provides an option that balances sustainability with practicality. With its growing availability, seamless integration into existing infrastructure, and ability to reduce emissions, renewable propane is now positioned to play an important role in the future of clean transportation.

Decisiv/TMC report: Parts and labor costs down in Q4 2024

The new data reverses the trend reported in Q3 of 2024, with both parts and labor costs decreasing independently.

By Lucas Roberto

NASHVILLE—After going up in Q3 2024, parts and labor costs dropped 1.6% in Q4, according to the latest Decisiv/TMC North American Service Event Benchmark Report. e news was

presented at the TMC 2025 Annual Meeting & Transportation Technology Exhibition in Nashville, and is based on Vehicle Maintenance Reporting Standards for the top 25 systems, representing 97% of service events.

e 1.6% drop reﬂects an anticipated decline in service activity following traditionally higher pre-holiday freight volumes in the third quarter of each year, the companies noted. e volume of service operations did increase 4.7%, though, and parts and labor still went down, which is notable to Decisiv CEO Dick Hyatt.

“Lower parts and labor costs are good news for service providers and ﬂeets a er last quarter’s increase,” Hyatt said. “While they indicate that parts supply chains are more stable and there is improved continuity in the ranks of technicians, the data also shows that service operations are handling an increase in events more productive-

ly and e ciently. With more e ective service management, communication, and collaboration practices between their in-house operations and dealers, ﬂeets are realizing how best practices can lead to a better bottom line.”

In Q3 2024, parts and labor costs went up in 19 of the 25 systems tracked. In Q4 only nine went up. Aero systems saw an uptick, while transmission, drivetrain, and rear-axle systems all went down. is news was tempered by the volatility surrounding the Trump administration’s reciprocol tari s, expected to go into e ect April 2. Jack Poster, VMRS manager for TMC, has been discussing with ﬂeets how tari s will impact parts costs and he said, “All of their vendors have said, ‘You’re getting the price increase.’

“And the sad thing is they all said, ‘Once they increase it, they never bring the price back down,’” Poster added.

Use of AI

Robert Ziemba, Decisiv VP of marketing, explained that this year the company embedded the machine learning algorithm directly into the Decisiv platform, enabling real-time analysis of service operations that aren’t already encoded with VMRS codes. is results in a much more comprehensive survey, with fewer operations le unencoded.

As the technology progresses, even more insights and e ciency should be revealed, Poster asserted.

“AI is the most exciting thing to happen to VMRS in the history of VMRS,” he said.

He said machine learning and automation will speed up work order creation, and the data will also be more accurate, and by extension, more valuable. ere’s only one thing Poster regrets about all of it.

“I wish I was a lot younger so I can stick around to see what’s gonna happen, because it’s amazing,” he said.

Parts and labor

Similarly to the results of last year, powerplant (045) accounts for around a third of service costs, with another third split between exhaust (043) and “other”. e ﬁ nal third is made up of eight categories, with cooling (042) and brakes (013) leading at around 6%.

Despite the overall decrease, there were a few increases in parts and labor costs from Q4 2023 to Q4 2024:

Ü Aerodynamic Devices (004): 6.3%

Ü Transmission - Main, Automatic (027): 5.8%

Ü General Accessories (051): 5.3% Aerodynamic devices (004) saw a jump of 6.4% from Q3 to Q4 of 2024 alone.

Here are the signiﬁcant decreases in P&L costs YOY:

Ü Transmission - Main, Manual (026): -8.9%

Ü Axle Driven

Ziemba suspects that the proliferation of automated driver features and ADAS could be a likely suspect in driving costs down in these categories.

Future outlook

Q4 of 2024 marked the first reporting period that labor costs fell in “quite a while,” according to Ziemba.

“Even though overall parts and labor were coming down, usually labor was going up and parts were coming down more to compensate it, so the overall cost structure is coming down,” he explained, noting that labor costs have come down 1.9% for the quarter and almost a full percent YOY. “This could point to better technician retention, because that has been one of the key issues driving labor costs.”

All in all, Ziemba and the company are optimistic that last quarter’s report is not indicative of a trend, and that labor costs will continue to fall.

“We’ll continue to monitor this, but it’s very good news that last quarter seems to be an anomaly, and that we’re seeing parts and

labor costs coming back down,” Ziemba said.

How the data was compiled

The data in the report is based on service and repair events entered through Decisiv’s service relationship management (SRM) platform, which uses an AI machine-learning algorithm embedded in the platform to encode events with VMRS

codes. Decisiv analyzes service data from around 74,000 fleets with more than 7 million commercial vehicles total, tracking over 300,000 service and repair events per month.

Decisiv, which has run this report for more than five years, expanded its data collection from nine to 25 VMRS system classifications in 2023.

The full benchmark report is available to all registered TMC members.

Fullbay report: Labor rates, technician demand on the rise

According to the ﬁfth annual 'State of Heavy-Duty Repair' report from Fullbay, tech pay is also steadily increasing.

By Lucas Roberto

NASHVILLE—While challenges and uncertainty persist in the commercial repair industry, there are reasons to be optimistic, according to Fullbay CEO Patrick McKittrick, based on the results of the shop management platform provider’s ﬁ h State of Heavy-Duty Repair Report.

e report was derived from more than 950 validated industry professionals surveyed last fall and data from 3,500 Fullbay customers (who used the platform for more than one year).

At a roundtable held at the 2025 TMC ATA Annual Meeting at the Music City Convention Center, McKittrick revealed that 56% of those surveyed said that business in 2024 was either “signiﬁcantly better” or “slightly better” than 2023; 17% said it was “a little worse,” with a scant 3% saying things were “a lot worse.”

“And that was encouraging to me, especially considering the timing and leading up to an election where there was a lot of uncertainty,” McKittrick said. “We saw people actually pleased with the way their businesses were performing.”

But timing is everything, and in the past month that optimism ignited by a new anti-regulatory administration has been marred by tari uncertainty, which could drive up the costs of assets, parts, and tools and shop equipment.

For now, the report o ers shop data such as stats on labor rates and technicians, as well as emerging areas such as fraud.

Labor rates

Labor rates continued to climb, Fullbay reported, with the current median labor rate of $134/hour. is indicated consistent growth, as last year the median was $130/hour, and $125/hour in 2023.

However, while labor rates continue to steadily increase to adjust for inﬂation, 45% of shops are assessing them just once per year, which

McKittrick says may be a missed opportunity.

“While the industry has done a nice job of actually adjusting their rates, I think they have le money on the table,” he said. “Evaluating your labor rate once a year is not enough. And if you’re not keeping up with real-time information, you’re going to miss out.”

Tech pay and benefits

On the note of technician pay, the numbers show that growth has continued from 2023-2024, though at a slightly slower rate. On average, tech pay has gone from $29 per hour to $30, a 3.4% YOY growth rate compared to the 7.4% that occurred over the previous reporting period.

“It was actually surprising that technician pay didn’t rise a little bit faster through the year,” McKittrick said, noting that the number of new techs coming into the workforce, is “troubling.”

Incentives and bonuses are also a growing part of shop beneﬁts, and Fullbay found two-thirds o er health insurance as an incentive.

“ is is an alarming statistic that may show why so many shops are having a hard time hiring techs,” noted Peter Cooper, CEO of Ascend Consulting, in the report.

Shop fraud

Fleet managers are familiar with fuel fraud, but there’s also fraudulent activity within the shop. is can occur in a few ways, one of the most common being ‘friendly fraud’, “people who were real customers, who did real transactions, who then disputed charges under somewhat questionable circumstances,” McKittrick said.

While this is o en resolved, the ordeal still eats up shops’ time. And the can cause issues, too.

“People with bad intentions that want to take

money will look anywhere they can, and some of them have started to look at commercial repair shops as places where there are high dollar items that you can purchase on a credit card,” he noted, “and once you’re out the door with them, it’s someone else’s problem.”

Most fraud is detected, “but it’s just a reminder the shops have to stay vigilant,” McKittrick said.

“We want the shops to be aware what’s going on so they can take the right actions,” he concluded.

Velociti rolls out VeloCare Unlimited to onboard technology

Dash cams are not much use when they don’t work, with a new VeloCare program from Velociti helping fleets get ahead of issues.

By John Hitch

Imagine this: You’re a safety-focused fleet with an obsessive emphasis on avoiding accidents, and pay subsequent attention to plaintiff’s lawyers seeking nuclear verdicts. You’re compliant with a well-trained team and documents all in order. Then a driver with a million safe miles gets into an accident, which he claims was staged by scammers looking for a big payday. But you find the dash cam that would have exonerated him was down. In fact, a third of your fleet’s video systems weren’t working, and because it’s not necessarily an uptime issue— and the trucks were working and parts were on backorder—the problem was not quickly addressed

Then in court, a jury finds your fleet failed in maintaining its video-based safety measures and you end up writing a huge settlement check.

That’s a very real scenario Velociti CEO Deryk Powell posed at TMC 2025’s Annual Meeting, where he introduced VeloCare Unlimited, which he says would help fleets avoid such a scenario.

Starting at $4/month per asset, VeloCare Unlimited provides fleets with real-time, 24/7 technology health monitoring, program management, inventory control, and unlimited repairs for covered vehicles.

The way it works is:

Ü The VeloCare monitoring system detects device problems

Ü VeloCare is notified to start a remote fix or to schedule repair

Ü Replacement part is shipped

Ü VecloCare techncian goes directly to vehicle or facility to make repairs

Ü Return Merchandise Authorization (RMA) is issued, unused parts go back to inventory and the process is tracked on VeloCare dashboard Velociti said all VeloCare services come with guaranteed Service Level Agreements and include technology inventory management.

“We understand trucking companies operate on razor-thin margins,” Powell

explained. “VeloCare Unlimited, at just $0.00048 cents per mile, is intentionally structured at an almost negligible cost …We strongly assert that fleets cannot afford to operate without VeloCare.”

This was proven by a fleet use case where during a Customer Health Audit, Velociti found 500 out of this fleet’s 3,000 total dash cam systems, or 16.7%, were non-functioning. This fleet’s historical data revealed accidents without a working dash cam cost $2 million more than those with a working one. Within three months, VeloCare technicians returned nearly 95% of those systems to working condition.

While technology hardware itself might not fail, (70% of the time issues are not related directly to the technology, the company said), in-cab power problems or damage from the driver can take a dash cam out of commission.

Citing VeloCare data from 2021 to 2024 tracking 1.1 million assets, Powell noted nearly 20% of fleets’ on-board technology will fail over the course of a year.

The top reason was driver tampering/ damage, then damaged windshield and vehicle power.

A fleet maintenance leader who gets an alert that a device failed on a truck operating away from an in-house service facility may not prioritize a repair, but Velociti would offer unlimited field service repairs, as well as device bench testing to verify reliability.

For instance, VeloCare contracted 100 local techs to assist one nationwide logistics company with nearly 10,000 pieces of tech on its 6,500 assets. And a public utility location uses VeloCare to maintain devices on 13,000 vehicles.

“The ROI resulting from healthy technology is clear,” Powell said. “As an example, the cost of defending an accident without the benefit of video footage is dramatically higher than the cost when video evidence is available. With VeloCare, customers can rest assured that their technology is doing its job.”

Clawing for more e ciency

Every shop struggles to do better, but less so with the right tools.

By John Hitch

The world is changing faster than ever, but one constant that remains in the maintenance game is that e ciency equals success. At the shop ﬂoor level, the way to do this is making sure your technicians have the training and tools they need to maximize throughput in the bay and uptime in the ﬂeets.

Most managers are already doing this somewhat, as the latest Fullbay State of Heavy-Duty Repair Report found four out of ﬁve shops o er PPE like safety glasses and gloves, with a third providing boots. e question is what kind of PPE are you providing: shoddy gloves that rip on a steel bracket or reinforced ones that o er protection and dexterity? Because if you cheap out, techs either won’t wear gloves or

they’ll slow down jobs. It’s the same with boots. Uncomfortable footwear can impact the whole body over time and cause missed work and less focus. Now consider how the wrong tools and equipment everywhere in the shop can cost you minutes or hours more per repair, to say nothing of what it tells employees about how you value their time and comfort. On this last point, remember that as the decade marches on, clawing for quality techs will likely turn the game of maintenance into an all-out war.

We hope this curated guide of the latest and gear and tools will help you prepare for that day, because picking winning tools for your shop now could very well determine your future.

Kaiweets KTI-W01 Thermal Camera

Diesel technician Missy Albin’s

ﬁrst

thermal imager experience has led to daily use in the shop.

Kaiweets’ KTI-W01 ermal Imaging Camera o ers ultra-high resolution, thermal sensitivity up to 50 mk, and a temperature resolution up to roughly 1 degree F. e camera features a wide temperature range of -4 degrees F to 1,022 degrees F and o ers infrared, visible light, and fusion image modes. It can also connect to a Windows PC with a USB cord for analysis, and the camera supports one-touch photo viewing and video recording. e KTI-W01 includes a built-in 3,500mAh rechargeable Li-ion battery that can support 6 to 8 hours of continuous work.

Fleet Maintenance: Have you ever used a thermal imager to diagnose truck issues before?

Missy Albin: I had always wanted a thermal imager a er playing with everyone else’s over the years. I was always fascinated by this technology as you can use it for so many purposes in and out of the shop, but I had no idea how useful it really was.

FM: What was your ﬁrst experience like using it on the job?

MA: Just like a kid with a new toy, I took it out of the box and I went around the shop, pushing every button so I could see what it did. en I had a fuel job come in. I didn’t expect to use it on this job, but I actually did. I had a crank no start and grabbed the imager, and on the high-pressure fuel rail, you could see on the imager the fuel restriction in the high-pressure relief valve. It was a quick and easy diag that I would otherwise have had to hook up to numerous lines to verify return ﬂow. e part was replaced and it ﬁred right up. In the same day, I found a shorted battery cell. at’s really something to see!

FM: What comes in the box and how is it powered?

MA: e camera is powered by a USB cable that plugs into your computer, which is also part of the charger that comes with the thermal camera.

FM: Talk about a feature you like.

MA: I love the video recording. is was so much fun to use because when I have an event going on like something shorting out, or using it on a running engine for fuel diagnostics, all I did was record it and I got to see the thermal image video, which is really impressive, especially when you have things shorting or heating up beyond visibility.

FM: How robust was it for heavy-duty trucking use? How is it stored to make sure it does not get damaged?

MA: I deﬁnitely don’t want to drop this, but I have knocked it around a bit and it’s okay. I keep this on my diagnostic tool cart in its original packaging.

FM: Do you see this as something you will use in the future?

MA: I use this daily, so yes. It is a staple on my diagnostic tool cart next to my multimeter and ﬂashlight.

FM: What features do you wish it had to make it more useful?

MA: I feel that it would be better if I didn’t have to limit my temperature setting to either one or the other.

For cordless tools:

• What type of battery does the tool have? Battery type determines how long the battery provides power and how much time is required for recharging.

• Consider battery voltages. Eight to 12V systems are more common for ratchets, lighting, and applications requiring lower rpm. Eighteen to 20V systems are most common for impact wrenches. Over 20V is available for extended applications such as grinders.

For pneumatic tools:

• Every air tool has an operational compressed air requirement measured in cubic feet per minute (cfm). Every air compressor has a maximum cfm output. The air compressor’s cfm output must be greater than the cfm requirement to keep all the pneumatic tools in the shop operating efficiently.

• Consider compatibility with existing systems.

A: e packaging is super cute. Mailing comes with their logo. ey do special gi s of custom Torq’d red work rags with every pants order. ey also include their sticker of the season along with a sparkly QR code thank-you card!

Q: What features did you like?

A: I am very aggressive in these pants while working. I don’t have to think about having to alter my wardrobe before I climb up something or go on the ground. Usually, I have to hike my pants up because they’re just too big or don’t ﬁt right.

Q: How durable are they?

A: e material is super durable and has withstood all of the jobs I have put them through.

Q: How do they compare to other pants you’ve used like them?

A: ese pants are holding up better than the competition pants out there, which fall apart faster.

Q: On a scale of 1 to 10, how would you rate them overall? Why?
