NACAT President's Update
Drew Barnes
Vale School District
Greetings Fellow NACAT Members,
It is hard to believe that as many of us are reading this update, we are already back in the shop, preparing for yet another successful school year. Summer just flies by! Hopefully each of one of you enjoyed some kind of a break to help you reset and get motivated for this new school year.
With it already being August, that also means that we just completed another very successful NACAT Conference. We had a great time in Indianapolis for our 50th anniversary conference. We had a fantastic list of training courses to choose from, with a variety of topics offered to meet the needs of all automotive educators. Thank you to all the educators that were able to attend, and if you were not able to attend, we are looking forward to seeing you next year. Also, a special thank you to all those who make this event possible each year. That includes our sponsors, industry partners, course instructors, hotel staff, and our business management team. This year’s event truly was outstanding; However, as with every year we are always looking for ways to improve to best suit the needs of our membership. With that being said, if you have not had a chance to complete the attendee survey, please do so as soon as possible. You should have received a link immediately following the conference. If you have any questions in regards to completing the survey please feel free to reach out to our business manager, Heather Sebben (heather@nacat.org). We truly appreciate the feedback from our members and attendees. If you have any suggestions or concerns outside of what can be shared in the survey, please feel free to reach out to me, any of the other NACAT officers, or board members.
As an organization, we are continually trying to improve/increase our member benefits. Currently, we are working on growing our instructor resources on the membership benefit section of our website. We would like to add more documents and quick resources to further assist automotive educators. We would like to encourage our members to donate to this endeavor, if you have anything that you would like to share please feel free to share that information with us. These items can be downloadable documents, videos, quick links, or anything else that you think would be a valuable resource to fellow members. Within these resources we are planning to include a section for teacher lesson plans, and we are encouraging our members to share specific content lessons that they have created and feel other teachers would benefit from. For more information on this or how to donate materials, please contact Heather Sebben.
Although we just wrapped our 2024 NACAT Conference, that doesn’t mean we aren’t looking to the future and making plans for the 2025 conference. For those who haven’t heard the news, we have already set the dates and conference location for next year. The 2025 NACAT Conference will be held June 9-12, 2025 in Detroit, Michigan! We are very excited about this location, as Motor City has so much to offer in regards to the automotive industry. Be on the lookout for updates about this event, as we continue to make plans for what may be the most exciting NACAT Conference yet!

How To Start a New Hydraulic Pump – My Life is in Your Hands!
The following outline provides a step-by-step method for starting a hydraulic pump correctly. Refer to Figure 2-1 for correct placement of diagnostic equipment.
1. Connect vacuum gauge (A) in parallel with the pump inlet port transmission line.
Why? It will offer visual indication immediately upon start-up of any problems related to the suction side of the pump. Pump manufacturers provide maximum inlet restriction specifications which should be strictly adhered to. Refer to the pump manufacturer's specification for maximum inlet restriction recommendations.
Some common pump inlet start-up problems:
1.1. Low inlet restriction
a. No oil.
b. Low oil level.
c. Loose connectors, filter, and/or clamps.
d. Case drain line above the oil - bent axis pumps.
e. Pump dry - not creating partial vacuum- mounted above oil level.
1.2. High inlet restriction
a. Pump rotating too fast.
b. Incorrect oil - viscosity.
c. Plugged inlet transmission line.
d. Suction screen incorrectly sized.
e. Suction filter incorrectly sized.
f. Suction line incorrectly sized.
g. Suction hose - not suitable for suction line applications.
h. Suction hose - kinked or crimped.
i. Reservoir/pump isolator valve closed or partially closed.
j. Reservoir/pump isolator valve incorrectly sized.
k. Ambient temperature extreme - oil viscosity.
NOTE: If the pump inlet port is incorrectly sized, it will not be detected by a vacuum gauge installed in parallel with the pump inlet port connector. If the vacuum or pump inlet restriction is within specification and cavitation persists, check the pump manufacturer’s specifications for pump inlet port size relative to pump flow.
2. Connect pressure gauge (B) in parallel with the connector at the outlet port of the pump. Where possible, disconnect the pump outlet transmission line, and connect it directly to the inlet port of the return line filter (5) or into the top of the reservoir (if the transmission line is placed directly into the top of the reservoir, it must be securely fastened).
Continued on Page 9
Why? Pressure control is not always the function of a pressure relief valve in a hydraulic system. Certain types of variable displacement hydraulic pumps have pressure compensators which control pressure in the system. Refer to the manufacturer's specifications for recommended pressure relief valve or compensator settings.
2.1. Compensators on new or rebuilt pumps are very rarely adjusted to suit a specific system. Compensator adjustment can be made before introducing the pump to the system.
2.2. Pump performance can be monitored under varying pressure conditions.
2.3. Pressure compensator adjustments can be made safely and accurately.
2.4. Pump manufacturer’s step-level pressure "run-in" procedures can be systematically followed.
Certain types of unbalanced pumps must be "run-in." Manufacturers provide a step-level pressure start-up recommendation. Step-level simply means that the pressure at the pump outlet must be applied gradually and in specific increments.
It is not uncommon for gear pumps, especially aluminum bodied designs, to experience gear-to-housing contact upon start-up. Some larger pumps will remove as much as a half-a-cup of aluminum on start-up. By running the pump outlet directly into the return line or "slave" filter, none of the excess material will enter the system. This procedure is especially important if high pressure filters are not installed in series with the pump outlet transmission line directly ahead of the pump.
About 90% of rebuilt pumps are either not tested, or are not tested to maximum pressure and flow levels. This is due to either an absence of test capability, or insufficient test-stand horsepower.
3.Connect flow meter (D)
in series with the pump outlet transmission line.
Why? Satisfactory actuator speed and system performance is dependent on the amount of oil delivered by the pump under various load conditions. Pump flow must be consistent with pump volumetric efficiency and design requirements. Refer to manufacturer's specifications for recommended pump flow specifications.
EXISTING SYSTEM:
1. Suction screen
2. Pump/Isolator valve
3. Pump
4. High pressure filter
5. Return line filter
DIAGNOSTIC EQUIPMENT:
A. Vacuum gauge
B. Pressure gauge
C. Needle valve
D. Flow meter
E. Pyrometer
F. Tachometer

Attendees to the annual NACAT Conference & Expo are able to take advantage of exceptional industry training while being able to network with peers from schools throughout the United States and Canada. Many go to a first conference not knowing what to expect, but come away life-long friends and training partners with whom they can share information and practices to create the best classroom and laboratory experiences possible.
"I've made lots of great peer contacts through the NACAT conference. We've been able to share ideas, discuss what works and doesn't work, and learn in a group setting through training classes. It's a much better use of my time and my district's funds to attend the NACAT conference than to send me to a "normal classroom teacher" professional development conference."
Thomas Pitt, Hardin County Schools
"Talking all week with like minded people, networking, and meeting future partners, that's what it's all about. Top it off with eye opening classes, getting to work on new electrical boards...Had a great time. Well worth the trip. Other members as well as the trainers."

NACAT Valve Cover Racing: Taming the Environment to Rule a Continent!
The annual NACAT Conference Valve Cover Races, this year sponsored by ConsuLab, were first run at the 1999 conference. Since that time the event has grown in popularity with all who venture to a NACAT conference. There are outstanding racers crafted in Canada and many gravitational chariots made in the USA. Women, men, and children of all ages endeavor to stay just within the rules to make the quickest accelerating, highest velocity obtaining, straightest coasting vehicle to ever run down the NACAT Valve Cover Race Track.
While many battled the track, gravity, friction, mechanical problems, and more in an attempt at victory, we send CONGRATULATIONS to NACAT 2024 CHAMPION Drew Jablonowski, from Garage Gurus, who won the overall title with the super speedy downhill dueler originally crafted by Laurie Dwyer. He was fortunate to win the racer in NACAT's scholarship fund-building silent auction.
Mitchell 1 Names Ty Rockney 2024 Automotive Technology Outstanding Student
Ty Rockney of Chesapeake, Virginia, has been named the 2024 Mitchell 1 Automotive Technology Outstanding Student – a recognition that includes a $2,500 scholarship and an all-expenses-paid trip to attend the 2024 North American Council of Automotive Teachers (NACAT) conference.
As part of the scholarship program, administered through the University of the Aftermarket Foundation, Mitchell 1 annually honors a U.S. or Canadian student for their outstanding achievement in automotive technology and auto shop repair scholastics.
“We are proud to recognize Ty Rockney as the 2024 Mitchell 1 Automotive Technology Outstanding Student for his dedication to pursuing a career in the auto care industry,” said Nick DiVerde, senior director of product management for Mitchell 1. “We have full confidence that he will accomplish his goals and thrive in his career path.”
Rockney is currently enrolled in the automotive technology program at the Advanced Technology Institute (ATI) in Virginia Beach, Virginia. After his graduation in January 2026, he plans to work as an automotive service technician and aspires to become an instructor or own a repair shop.
Rockney discovered his passion for automotive repair after receiving a 1997 Dodge Ram 1500 for Christmas in 2020. His father initially assisted him, but he soon took the initiative to research, purchase parts and work on the truck himself. His great uncle, a technician since the 1970s, also inspired his career choice.
The award was presented during the NACAT awards luncheon on July 24, in Indianapolis, Indiana.
Congratulations, Ty!

Adding Hybrid and Electric Vehicle Technology to a Basic Electrical Class
As I write this article, the summer instructor conference schedule is nearly complete. I have enjoyed seeing many of you during my travels. A question that was frequently asked during, or after, my presentations was: How can I add high-voltage electricity and components to our existing curriculum? This is a great question and an excellent way to add hybrid and battery electric vehicle technology materials to the existing classes and increase the interest level in the topic at the same time. I believe the basic electrical classes are a great place to start adding hybrid and electric vehicle content. In this article I will share some ideas and concepts that will help begin the process.
Every basic electrical class covers the measurements of volts, amperes, and ohms. When covering ohms, introduce milliohms at the same time. The students will find it very interesting to see how differently a CAT III multimeter (set to ohms) and milliohm meter will measure the resistance of various lengths of stranded 14-gauge wire. The items shown in photo #1 are used in the milliohm measurement lab (See Photo #1 – Milliohm Meter). Although the measured resistance difference will have little impact on the diagnosis of a tail-light circuit, it makes a major difference when trying to identify a concern with the stator windings in a drive motor.
During the discussion of circuit protection, the operation and diagnosis of fuses, relays, PTC devices, and fusible links are covered. An excellent way to add high-voltage technology to the conversation is to include the topic of pyro fuses (See Photo #2 – Tesla Model S Pyro fuse). These circuit protection devices can be found in a high-voltage battery or the disconnect plug. The pyrotechnic materials used in the fuses are like what is used in an airbag module and ensure the high-voltage circuit is opened rapidly in the event of a short circuit or an airbag deployment.
The topic of AC electricity has almost disappeared from the basic electrical class. Other than a brief mention of AC ripple voltage when diagnosing an alternator output concern, it is hardly mentioned. The operation of electric drive motors is a great way to make this topic relevant to the class. The use of a permanent magnet trainer and an oscilloscope is a great way to help our students visualize the difference between AC and DC electricity (See Photo #3 – Trainer and Photo #4 – Scope pattern on the facing page). The single waveform generated on the oscilloscope shows the transition between positive and negative voltage and the total energy potential of the circuit. The same principles can also be applied to brushless AC blower motors and fuel pumps, which are becoming more common.
Continued on Page 19

Photo #2: Tesla Model S Pyro fuse
Lastly, students are always interested in discussions related to powertrain torque and horsepower. During these discussions, include topics such as kilowatts (kW), newton meters (Nm), and kilowatt hours (kWh) and how they are used to measure electric motor power output, torque, and high-voltage battery storage capacity. Make some side-by-side comparisons between electric and internal combustion engine vehicles. The students will be amazed to see how strong an electric motor performs.
None of the suggested ideas or concepts require the program to invest in an electric vehicle. With a relatively small investment in a milliohm meter, and pyro fuse and blowing the dust off the old permanent magnet trainer, the basic electrical class now includes some of the fundamentals that would be covered in a hybrid or electric vehicle class.
I will finish this article with the same offer I make after each of my presentations. If you are interested in getting started in the process of adding hybrid and electric vehicles to your curriculum or want more information, please feel free to reach out. I am more than willing to sit down in-person or online and share my experiences. Are you looking for a classroom textbook? Reach out to Pearson and ask for a review copy of the all-new Electric and Hybrid Electric Vehicle text that Jim Halderman and I co-authored. It is a comprehensive text covering all the latest information on the subject. Continued From Page 18

NACAT Names Dayne Van Dyke Larry cotten memorial scholarship recipient
Dayne Van Dyke was named the 2024 Larry Cotten Memorial Scholarship recipient during the NACAT Conference & Expo which was held July 22 - 25 in Indianapolis, Indiana. The $1000 scholarship is given in memory of Larry Cotten, a NACAT Charter member and former president. Cotten’s wife and family established the memorial scholarship, following his death in an accident in 2005, to help pass his passion on to the next generation of collision repair technicians.
Van Dyke is enrolled as a student at Kirkwood Community College in Cedar Rapids, Iowa. He stated that remote learning during Covid cemented an office job was not his passion, as he felt something was absent. He found that missing piece as he acquired an older Chevy Silverado and began to enhance and modernize it daily, just as soon as his online classes would end. As a result, during his senior year he enrolled in the dual credit automotive collision repair and restoration program at Kirkwood Career Academy.
“NACAT congratulates Dayne as he embarks on his automotive career,” said Drew Barnes, NACAT President. “We also would like to thank and congratulate the University of the Aftermarket Scholarship program for the automotive scholarship website, www.automotivescholarships.com, which for the previous academic year helped facilitate the awarding 385 scholarships totaling $642,750. The platform makes it easy and enjoyable to rate and review applicants with information that is up to date and valuable. We are proud to be a part of helping students, like Dayne, achieve their goals and dreams. We look forward to knowing the composite numbers for the upcoming school year.”
Dayne was very gracious in his acceptence, as he stated, "I would like to thank you for your generosity in awarding me this scholarship. This scholarship provides me a straight path to achieving my goals."
Congratulations, Dayne!

NACAT REcognizes: Fritz Peacock and Al Santini
NACAT President Drew Barnes recognized Fritz Peacock and Al Sanitini for their lifelong committment to NACAT during the opening session of the 2024 NACAT Conference & Expo held in Indianapolis, Indiana.
Fritz Peacock is a NACAT Charter Member and Al Santini has been a NACAT member for 45 years! Each has shown unwavering support which has been instrumental in NACAT’s evolution and success. Thank you, Fritz and Al, for your commitment and passion for automotive education and the impact you continue to make in the field.

3.1.The flow meter will:
a. Indicate if the pump is receiving oil at its inlet port.
b. Indicate if the correct amount of flow is being delivered to the system.
c. Indicate an abnormal variation in pump input speed.
d. Indicate pump efficiency under various load conditions.
e. Allow you to make flow adjustments on pumps equipped with mechanical flow adjustment options (variable displacement).
4. Connect needle valve (C) in series with the pump outlet transmission line.
Why? Pump efficiency can only be accurately measured when the pump is pumping against a pressure (load). A needle valve can be used to generate an “artificial” load at the pump outlet to check pump flow at various pressure levels.
4.1. Gradual loads can be introduced at the pump oulet easily without having to load the actuator(s).
4.2. Manufacturer’s start-up procedures can be followed more easily. Certain manufacturers require that pumps be loaded sequentially at step-level pressures for optimum in-service performance.
4.3. Many new and rebuilt hydraulic pumps are not tested under full pressure and flow conditions. This is primarily due to a lack of test-bench horsepower. Therefore, the prime mover can be used as a “dynamometer” or test bench, as it has the horsepower capability to operate the pump at full flow and pressure levels.
4.4. Contamination from catastrophic pump start-up failure will not be transported into the system.
4.5. Warranty claims can be dramatically reduced as a well-documented systematic start-up procedure can rarely be argued against.
5. Check the pump input shaft speed using a tachometer.
Why? Pump flow is directionally proportional to shaft speed. The combined volume of the pumping chambers through one shaft revolution (360º) is called "pump displacement", and is usually expressed in cubic inches per revolution (CIR). An abnormal increase or decrease in shaft speed will have an adverse effect on pump life. Refer to the manufacturer's specification for recommended prime mover speed.
5.1. High Speed Related Problems
a. Bearing life is inversely proportional to pump speed. A pump operating at 1800 RPM will have a life expectancy about 50% lower than one running at 1200 RPM.
b. Excessive speed will result in cavitation because inlet transmission lines may be undersized for the increased velocity, and suction screens may be undersized for the increased flow.
c. Pump balancing is also critical to shaft speed. Excessive speed may cause vibration due to the increased centrifugal force on unbalanced rotating groups.
d. Lubrication may be affected by increased centrifugal force "squeezing" the lubrication film out, causing adhesive wear.
e. Cavitation and vibration will also produce excessive noise.

Low Speed Related Problems
a. Mobile equipment is particularly vulnerable to prime mover speed reductions due to wear in foot throttle to fuel injection pump linkages and cables.
b. A pump becomes less efficient at lower speeds because of internal leakage which is proportional to system pressure and pump design clearances. Leakage is a higher percentage of reduced flow rates.
Motor Testing
Hydraulic motors typically slow down under load when worn. Historical analysis will determine that the problem is viscosity sensitive, i.e. during cold start-up operation they appear to operate normally, and as the oil temperature increases the motor shaft speed decreases.
6. Monitor the oil temperature using a pyrometer.
Why? Monitoring and maintaining oil at a moderate temperature is essential for reliable machine operation. When hydraulic systems are started up, the oil temperature will increase until it reaches a "levelling-off" temperature. This condition occurs when the heat being generated is equal to the heat being removed by radiation through the walls of the reservoir and/or by a heat exchanger. Refer to the manufacturer's specification for maximum & minimum operating temperatures.
6.1. Machine tools and plant power units operate at temperatures between 140ºF (60º C) and 160ºF (71ºC). Mobile equipment systems are forced to operate at temperatures up to 180ºF (82ºC).
6.2. Systems should never be allowed to operate at temperatures above 200ºF (93ºC). At this temperature and above, oil life is greatly reduced.
Viscosity may decrease to a point where:
a. Power loss becomes excessive.
b. Lubrication loss may result in adhesive wear.
c. Rubber seals and filter elements may deteriorate rapidly.
6.3. Studies have shown that oil life decreases by approximately 50% for every 20ºF (-6.6ºC) rise in temperature.
6.4. A pyrometer should be used on a daily basis to allow the user to become thoroughly familiar with system temperatures under all load conditions. Cold ambient conditions will also contribute to poor pump life. High viscosity will cause excessive pump inlet restriction resulting in cavitation.
Troubleshooting - Root-Cause Analysis
Introduction
Many premature hydraulic component failures are attributed to poor initial start-up procedures. It is therefore essential to implement strict guidelines when starting new systems or introducing new components to existing systems. This will optimize component reliability and maximize component life.
Common system/component start-up pitfalls
There are some obvious and not so obvious reasons why start-up failures occur:
a. Accumulated contamination in reservoirs, transmission lines, and components during manufacture or repair.
b. Tape and liquid-type connector and pipe sealants used to seal connections.
c. Pieces of rubber from hose assemblies, "O"-rings, and cylinder packings.

of the Year
Jay Kuykendall, an automotive instructor at Portland Community College in Portland, Oregon, has been named the 2024 Mitchell 1 Educator of the Year. The award was presented at the North American Council of Automotive Teachers (NACAT) awards luncheon on Wednesday, July 24, in Indianapolis, Indiana.
“We are proud to congratulate Jay Kuykendall as the 2024 Mitchell 1 Educator of the Year,” said Nick DiVerde, senior director, product management for Mitchell 1. “With 32 years of experience in the automotive industry, Jay is not only an outstanding teacher and a master automotive technician, but he is also a successful business owner. We are pleased to acknowledge Jay’s exceptional contributions to the classroom and the auto care industry as a whole.”
Each year, Mitchell 1 recognizes one of the nation’s top teachers for their commitment to educational excellence in the automotive repair industry. As the 2024 recipient, Kuykendall received a complimentary one-year subscription to Mitchell 1’s ProDemand® auto repair information software, a one-year membership to NACAT, and an all-expenses-paid trip to attend the NACAT conference.
In his position at Portland Community College, Kuykendall runs the auto shop lab and teaches engine performance classes as well as elective courses including Subaru U, electrified vehicles and light duty diesel. He is also a certified ASE Master Technician, owns and operates Green Flag Auto Repair in Molalla, Oregon, and is co-founder of the Northwest Automotive Technicians Society.
Kuykendall shared that his interest in the automotive industry began in his childhood. “I grew up with my family racing at the local short track. I helped my dad and brothers work on the race cars, and in high school, my sport was drag racing,” he said. “After high school, I attended trade school and started working in the automotive field right after graduation.”
The Mitchell 1 Educator of the Year award selection criteria requires that the recipient excel in all ASE automotive tests, including A1 – A8 (Engine Repair, Automatic Transmission/Transaxle, Manual Drive Train and Axles, Suspension and Steering, Brakes, Electrical/Electronic Systems, Heating and Air Conditioning, Engine Performance), as well as the L1 (Advanced Engine Performance Exam).
Congratulations, Jay!

d. Burrs from connectors, tube assemblies, metal fabrication, substandard replacement parts and component machining practices.
e. Substandard component storage methods, ports not plugged adequately, masking tape and duct tape covering ports, or rags in ports.
f. Sub-assemblies being "borrowed" from inventoried components leaving the housings open to the elements.
g. Sub-assemblies being "borrowed" from existing operating systems to conduct "process-of-elimination" diagnostic procedures.
h. Due to design clearances, certain "fixed clearance" pumps will not "pick-up" oil upon initial startup. Oil is needed to create a "seal" to initiate a partial vacuum.
i. Pressure manifold systems which are not equipped with air-bleed valves, can cause the pump to become "air-bound." This condition will prevent the pumping chambers from filling with oil.
j. Pump and motor housings are not filled with oil prior to start-up which can cause excessive bearing temperatures and loss of lubrication.
k. Plastic plugs which are inadvertently left in component ports upon start-up.
l. Incorrect prime mover input speed.
m. Incorrectly installed components.
n. Incorrectly adjusted components.
o. Incorrect components.
p. Incorrect rotation of prime mover.
q. Rags or cloths left in reservoir or reservoir transmission lines during fabrication.
r. Reservoir/pump isolation valve left closed upon start-up.
s. Incorrect oil.
t. Return line, directional control valve, heat exchanger, and associated components sized for pump flow rather than cylinder flow.
u. External pressure control valve drain lines inadvertently plugged.
v. Pump and motor case drain lines incorrectly plumbed, sized, or inadvertently plugged.
w. Incorrect hose type used on suction side of pump.
Coming together is the beginning. Keeping together is progress. Working together is success. Henry F d
