CRAWLER UNDERCARRIAGE COMPONENTS Undercarriage components make up a major cost of purchasing, owning and maintaining a crawler dozer.

Equipping a dozer properly with the right undercarriage components can maximize up time productivity and minimize operating expenses. In selecting the proper undercarriage items such as application usage, soil conditions, types of chain assemblies, sprocket types, shoe widths, and maintenance practices should be reviewed with your customer.

Case offers several choices to fit a variety of applications and needs: CASE SEALED TRACK: (C.S.T.) This assembly is a non-lubricated system between the pin and bushing. To prevent contamination from entering into the pin and bushing area, metal seals are located on both sides of each bushing. This option provides good wear life, but wear still occurs on the pin and on both inside and outside diameters of the bushing.

CASE LUBRICATED TRACK: (C.L.T.) This assembly is sealed (oil seals) and lubricated with an oil reservoir in each pin. Each pin and bushing are sealed to keep contamination out and lubrication in. This option provides excellent wear life. Although wear between the pin diameter and inside bushing diameter is eliminated because of the lubricant, outside bushing wear still exists.

CASE EXTENDED LIFE TRACK: (C.E.L.T.) This system uses lubricated track with a large diameter bushing that is free to rotate on the standard bushing. This allows wear to be distributed over the entire circumference of the outer bushing. Because the bushing is free to rotate, it does not create the scrubbing action between the sprocket and bushing as the conventional crawler track chain does. The service life has doubled (Case Test) with this design and is recommended for HIGH ABRASIVE AND LOW IMPACT applications where bushing and sprocket wear may be severe.

SPROCKET TYPES: Types include standard for most applications, relieved which is to be used in extrudable material, rubber track only, wide track option and sprockets for extended life track.

Low Impact: Track shoe grousers will completely penetrate the ground surface with little or no rock or other irregularities.

High Impact: Track shoe grousers will not penetrate the ground surface. Large rock or large irregularities cause high impact loads on the undercarriage system.

RUBBER TRACK: This assembly is specifically designed for job sites requiring minimal surface damage.

Useage includes working on finished surfaces, preparing job sites for driveways, or sidewalks, or highway and street work. For 550G models only and should not be a substitute for applications requiring steel track.

SHOE WIDTHS: Dependent on the machine, standard widths may vary from 16 inches to 34 inches. The shoes must provide adequate traction and flotation, but no wider than necessary. Flotation is the ability to stay on the surface of soft ground or mud. Correct flotation occurs when the grouser bar penetrates into the ground without letting the shoe go below the surface.

MAINTENANCE: Correct track tension is important.

Check the track tension frequently when operating.

W h en wo r kin g in mu d , sn ow, a n d so m e sa n d y conditions, check the track tension more often. A loose track or a track that is too tight will accelerate track wear.

Abrasive Soils: Each type of soil a machine works in has a different level of abrasiveness. Generally, the higher the abrasiveness, the higher the wear rate.

Low Abrasiveness: Silts and clays are in this category.

When wet, this type of soil feels slick and can be easily molded.

Moderate Abrasiveness: Silts and clays that contain a low amount of rounded sand particles and enough moisture to stick together are in this category.

High Abrasiveness: These soils contain a high amount of sharp, irregular - shaped sand particles.

Impact: Impact is best described as the amount of grouser penetration on the ground. The effect of high impact loads can be reduced by reducing the machine speed and by using the smallest track shoes possible.

Field Test History of C.E.L.T.

Wear Area

In 1992, Case began customer field evaluations to determine wear comparisons with C.E.L.T. and C.L.T. tracks. The results showed that track bushing and sprocket life doubled in severe, abrasive conditions with C.E.L.T. C.E.L.T. is recommended for use in highly abrasive, low impact applications where bushing wear is severe, for example, sand, dir t and clay. As with conventional or lubricated track, the narrowest possible track shoes that will give adequate flotation should be used to attain maximum life.

The rotating bushings have 88% more wear area on the s p ro cke t a n d th e bu s h in g ro t a te s to a llow fu ll circumference wear.

We have accumulated over 10,000 hours of field testing on C.E.L.T. units in various parts of the country. The tests were run with conventional lubricated track on one side of the unit and C.E.L.T. on the other side of the unit in order to achieve a true comparison.

A Case Extended Life Track uses a different sprocket, which has more backup stock under the tooth root, and the tooth thickness has been greatly increased to enhance wear.

One of these tests was run in the Houston, TX area on a 550E. At 765 hours, we removed the standard chain from the unit and disassembled it to check internal and external wear. The bushing on this conventional track were worn 72%. We did not remove the C.E.L.T. A new conventional track and sprocket were installed. We continued to operate the machine with the original C.E.L.T. and the new conventional track for an additional 1107 hours. The second conventional track was removed from the unit at 1107 hours and showed 100% wear on the bushings and sprocket. The C.E.L.T. was measured at that time also, with a total of 1,872 hours and was found to have only 48% external wear on the floating bushing.

Bur 7-10142NA

The sprockets have 40% more back-up stock under the tooth root area and the wear material between each tooth has more than tripled over the conventional sprocket.

Minimum heat treat depth has been increased 20% on C.E.L.T. components.

UNDERCARRIAGE WEAR AND MEASUREMENT This section is to help you understand how track wear occurs and what you can do to get the most out of your undercarriage components.

Monitoring wear is one of the three main elements in maximizing an undercarriage investment. Monitoring wear helps anticipate when to make the pin and bushing turn and when to service or rotate components.

Also, by measuring wear and using the wear charts that are available for your machine, you will be able to determine the remaining life of all the components.

Record Keeping The undercarriage parts are measured to determine the amount of wear and to tell when repairs or replacement of parts is required. Keeping a good record of these measurements can tell you when your machine will be taken out of production for service.

The special forms for recording measurements and other information are available from your Case dealer (Form Number Bur 8-18791).

Wh e n a cus tome r buys a n ew pie ce o f tracked equipment, approximately 20 percent of the purchase price is in the undercarriage. As repairs become necessary, approximately 50 percent of the overall maintenance cost will be maintaining the undercarriage.

With this type of expense, the owner or end user will greatly benefit from a detailed explanation of how undercarriage life can be extended.

Before Measuring

Track Simulator

Make sure that you clean each component before you make the measurement. Use the scraper tool that is provided with the kit and a piece of emery cloth is necessary.

We w ill b e u s in g t h e C a s e Tra ck S imu l a to r t o demonstrate the varying conditions of track wear.

Each time you measure an undercarriage, carefully record all measurements on the Track Component Appraisal Form. Complete the report by comparing your measurements with the percent worn charts. Then record the wear life percentage remaining.

Replacement of worn components with new parts is one solution to undercarriage wear. However, there are other methods to prolong the life of your undercarriage.

Rebuilding B921008

Rebuilding is the process of welding or adding material to the worn surfaces of a component. Then the component is machined to original dimensions. Rebuilding is an alternative to replacing with new parts. While rebuilding is an inexpensive way of gaining additional life from worn components, this is not a recommended practice for small undercarriage parts. The extreme heat created by welding can cause warpage or changes in the molecular structure. Always use an experienced rebuild shop.

Case Track Simulator New track components must never be used or mixed with worn track components. Mixing new undercarriage components with worn ones will greatly decrease the life of the new components and accelerate the wear of the worn parts.

Repositioning Repositioning is a method of extending the life of worn components. In addition to turning the pins and bushings, you can also change the sprockets from side to side. This is only if the reverse wear is much greater than the forward wear.

The front and rear track rollers will generally wear faster than the middle rollers. If they are all the same type (single flange or double flange), it is possible to rotate the rollers. See the service manual for your machine for the correct procedure.

If the machine has been run on a side slope for an extended period of time, the wear patterns can differ from one side of the machine to the other. The same can be true of the undercarriage that is not aligned correctly.

Additional life can be obtained by moving undercarriage components from one side to the other.

UNDERCARRIAGE COMPONENTS

BD99J230

To fully understand the undercarriage, it is important to understand the purpose of each component. It is also very important to know how that component functions with the other components in the system.

8. TRACK FRAME - The track frames are attached to the machine chassis on each side. All of the track components except the drive sprockets are attached to the track frames.

1. DRIVE SPROCKET - The drive sprockets transmit engine power to the tracks. The drive sprockets do not support the weight of the machine.

9. TRACK LINKS - A number of track links make up the track chain assembly. Each link assembly consists of a right-hand and a left-hand link, a track pin (solid with sealed track chains and hollow with C.L.T track chains), bushings and seals. Each link assembly is bored at both ends to hold the pins and bushings that connect the two links. The bushing is pressed into each link. A pin is inserted through the bushing and the next set of links is pressed onto the pin. Sealed Track and Case Lubricated Track Chains are illustrated on page 1-26. Case Extended Life Track chain is illustrated on page 1-28.

2. CARRIER ROLLER/S - The carrier roller/s are mounted on the top of the track frame to support the track chain between the drive sprocket and idler. This roller also helps to maintain alignment of the chain between the idler and drive sprocket.

3. TRACK CHAIN - The track chain includes a number of link assemblies that are connected together to form a complete chain. Shoes are bolted to the track chain to provide traction for the machine. The drive sprocket rotates the track chain around the undercarriage assembly.

4. IDLER - The idler carries the track chain around the front of the track frame. This assembly can slide forward or rearward on the track frame against the recoil spring to absorb any shock loads. These shock loads can be from changes in the terrain or temporary material buildup on the track chain or sprockets.

5. TRACK ADJUSTER - The track adjuster is a grease filled hydraulic cylinder used to maintain or adjust track tension. To change track tension, add grease or remove grease from the track adjuster.

6. RECOIL SPRING - The recoil spring is used as a shock absorber that cushions large impact loads and also aids in maintaining correct track tension.

NOTE: It is important to understand the construction of the track chain. The pins and bushings of the sealed track are generally the first items of the undercarriage to wear. This wear can (and will) affect the rest of the components in the system. This will be further discussed in the section Wear Patterns.

10. TRACK SHOES - The track shoes are installed on the track chain to give traction and flotation for the machine.

11. TRACK GUIDES - The track guides help to maintain alignment of the track chain and protect the track.

UNDERCARRIAGE COMPONENTS AND WEAR

UNDERSTANDING UNDERCARRIAGE WEAR The factors that affect wear are very diverse. The most important wear factor is track tension, but other factors like speeds, soil conditions, the operator, the size of the machine, and high or low impact ground surface are also variables that affect wear.

You cannot stop undercarriage wear - even if you have the best design and top quality parts. You can, however, extend the undercarriage life if you understand the causes of wear.

Wear You Can Not Control

Pa ck in g ma t er ia ls c a u se a mis ma tc h b e tw e e n components, par ticularly between the chain and sprocket. The packing materials tighten the chain. This causes increased stress and strain on links, pins, bushings and the contact surfaces between mating parts.

For example, as mismatch occurs due to packing in the sprocket root, each track bushing rides higher in the sprocket. This condition causes rapid and severe forward and reverse wear and chain-to-sprocket “jumping” that is indicated by a loud “banging” noise. This results in high impact loads that cause additional wear and cracking.

Soil and underfoot conditions cannot be controlled.

These include abrasive soils, impact, packing, and moisture.

ABRASIVE SOILS Each type of soil a machine works in has a different level of abrasiveness. Generally, the higher the abrasiveness, the higher the wear rate.

Moisture also plays a major roll in abrasiveness of soils.

A sand slurry will be less abrasive than a damp sand, especially if that sand is packing in the sprocket roots and around the bushings. Wet abrasives act like grinding compounds.

LOW ABRASIVES - Silts and clays are in this category.

When wet, this type of soil feels slick and can be easily molded.

MODERATE ABRASIVE - Silts or clays that contain a low amount of rounded sand particles and enough moisture to stick together are in this category.

HIGH ABRASIVE - These soils contain a high amount of sharp, irregular shaped sand particles.

IMPACT Impact is best described as the amount of grouser penetration in the ground. The effect of high impact loads can be reduced by reducing the machine speed and by using the smallest track shoes possible.

LOW IMPACT - Track shoe grousers will completely penetrate the ground surface with little or no rock or other irregularities.

HIGH IMPACT - Track shoe grousers will not penetrate the ground surface. Large rock or large irregularities cause high impact loads on the undercarriage system.

Rocky terrain causes bending, breaking and chipping of the components. Reduce the machine speed and use the smallest track shoes possible.

PACKING Packing materials are any materials that stick to or pack around the moving components. To maintain correct track tension, the tracks must be adjusted as often as required when working in this type of soil condition.

Bur 7-10142NA

B408629V

This packing condition can also stop rollers from turning.

When this happens, the track chain slides over that spot on the roller. This sliding causes a flat spot on the roller.

Packing materials increase the abrasive effect of most material by not allowing the material to escape. Wear is then accelerated. Open center grousers or special relieved sprockets may help alleviate this problem.

Wear You Can Partially Control APPLICATIONS - The term “Applications” is often used to describe underfoot conditions. In this section we will describe what the machine is doing without regarding the applications.

DOZING - This operation shifts the machine weight to the front causing a faster wear rate on the front rollers and idlers.

SPEED - Unnecessary speed directly affects the wear rate on pins, bushings and sprockets. The faster the speed, the faster the wear rate. High speed reverse accelerates bushing and sprocket wear. Wear rate is a function of speed and distance traveled, not just hours worked.

IMPACT - High speed will increase impact loading when there is low grouser penetration on hard surfaces or when working in rock.

Impact can cause structural problems such as bending, cracking or breakage of components. This can also affect pin and bushing retention and bushing cracking. And, if a chain is worn, can cause fractures.

Issued 04-05

Printed in U.S.A.

UNDERCARRIAGE COMPONENTS AND WEAR TURNING - Wear rate increases when tracks are slipping. Track shoe grousers are affected due to increased sliding between grouser and the ground.

TRACK SLIP - Wear rate on all components increases when tracks are slipping. Track shoe grousers are affected due to increased sliding between the grouser and the ground.

1-7

The machine weight is moved forward causing increased wear of the front rollers. However, due to the design of the track system, working downhill reduces the wear of the sprockets and bushings.

WORKING ON THE SIDE OF THE HILL

FAVORED SIDE OPERATION - Wear rates will increase on all components when only one side of the machine is favored. Wear increases as more power is applied to the favored side. Also, more packing and slipping will occur on the favored side.

REVERSE OPERATION - Avoid excessive use of reverse operation. This is not only non-productive use of the machine, but it also accelerates bushing and sprocket wear. See pages 1-12 and 1-15.

RIPPING, PULLING IMPLEMENTS, OR USING A HITCH OR WINCH TO PULL LOADS - This operation will shift the machine weight toward the rear, causing a faster wear rate on the rear rollers. Then, during severe applications, the sprockets and track bushings wear much faster.

UNDERCARRIAGE COMPONENTS AND WEAR

Wear You Can Control

●

Good operating techniques and a good maintenance program will help you to get the longest life from your undercarriage.

Decreased pin and bushing life, or decreased link life due to elongated pin and bushing bores. This is a result of the twisted links.

●

Possible loss of lubricant in the Case Lubricated Track or Case Extended Life Track pins. This will result in early pin and bushing wear.

TRACK TENSION Check the track tension frequently when you operate.

When working in mud, snow and some sandy conditions, check the track tension more often. Material will pack on the undercarriage parts and cause the tracks to become too tight. Always maintain the correct track tension and always clean the undercarriage when you are done for the day. See page 36 for complete information on track tension and track adjustment.

TRACK ALIGNMENT Correct track alignment is required to prevent early wear of the undercarriage components. When you replace parts of the track system, always see the service manual for your machine and check the alignment of the undercarriage components.

B920692 TP97B003

TRACK SHOES The shoes must provide adequate traction and flotation but must be no wider than absolutely necessary.

Flotation is the ability to stay on the surface of soft ground or mud. Correct flotation occurs when the grousers penetrate fully into the ground without letting the track shoes go below the surface.

Track shoes that are too wide can have a damaging effect on many of the undercarriage components.

Because the middle of the track shoe is fastened to the track links, the links act as a fulcrum and must absorb or transmit any leverage or twisting forces that occur as the machine moves over uneven or rocky terrain. All of the other components (sprockets, track rollers and idlers) resist and restrict the twisting forces of the links. As a result, most of the wear and damage caused by the twisting action affects the links, pins, bushings and track plate mounting hardware.

Listed below are some of the effects of wide track shoes: ●

Resistance to turning - results in wear on the shoe corners and twists the track chain.

●

Bending, cracking or breaking the track shoes, shoe hardware and links.

●

Constant problems with loose shoe hardware that makes the bolt holes larger.

●

Increased wear on links, roller flanges and idler flanges caused by constant twisting of the track chain.

Bur 7-10142NA

Mis a lig n m en t p ro ble m s w ill af fe ct mo r e o f t h e undercarriage components than any other cause of wear. Misalignment will cause accelerated wear on the track links, idler flanges, track and carrier roller flanges, sprockets and rock guards. Alignment problems can be caused by all of the following: ●

Bent or twisted track frames that are not parallel or perpendicular to the centerline of the machine.

Realign, repair or replace damaged or misaligned track frames as required.

●

Idlers that are misaligned vertically or horizontally or are not in line with the sprocket and carrier rollers.

Realign the idlers.

●

Sprockets that are not shimmed correctly or are not in line with the track and carrier rollers. Realign the sprockets.

●

Carrier rollers that are not in line between the sprocket and idler. Realign the carrier rollers.

IMPORTANT: Tight tracks will greatly increase the effect of misalignment by causing an increase in load between the components. Track tension must be checked on a regular basis - more often during packing conditions. See page 1-30 for the correct procedure to check and adjust the track tension.

EXTENDING UNDERCARRIAGE LIFE Track Adjustment and Inspection

●

Eliminating or reducing the controllable causes of wear is a primary factor in extending the life of the undercarriage.

Avoid frequent reverse operation. If necessary to work in reverse, keep travel speed to a minimum.

●

Constantly turning the crawler in the same direction will cause uneven wear.

●

Make sure that rock guards are installed before you operate in rocky conditions. Remove the rock guards before operating in packing conditions.

●

In freezing temperatures, clean the undercarriage more frequently and park the machine on planks or on a surface that will not freeze to the machine.

●

Keep the machine turns to a minimum. Turning adds stress and side wear to the components.

Undercarriage wear is an inevitable part of owning a tra ck m a c h in e. So o n e r o r la te r, eve n th e b e s t undercarriage will need to be replaced.

●

If possible, match the track shoes to the underfoot conditions. Use the smallest track shoe possible that will give good traction and flotation.

You can prolong undercarriage life by understanding the factors that contribute to wear.

●

Soil conditions are a major factor in determining the amount of life you can expect from an undercarriage.

Nonabrasive soils, such as silt and clay, cause the least amount of wear. Wet, sandy soils are the most abrasive and cause the most wear.

●

Working in rocky conditions and other surfaces, where the grouser bars do not penetrate, causes high impact and twisting loads on the track chains.

●

Minimize the effects of packing by checking track sag frequently when working in mud, snow, and wet sand.

Packing can cause track jumping and banging.

●

Severe packing of materials between undercarriage components causes wear by increasing track tension.

●

Running tracks that are too tight reduces bushing and sprocket life 2.5 to 3 times.

Proper care and maintenance is the simplest and most cost effective method of extending undercarriage life.

Conscientious scheduled maintenance and good operating habits will help keep operating costs and downtime to a minimum.

Now that you know the major factors contributing to track wear, here are a few operating and maintenance tips to he lp you ge t th e mos t life fro m you r mac hin e’s undercarriage.

Operating techniques and maintenance also greatly affect undercarriage life. Unlike the other wear factors that you can not control, you can do something about the way you operate and maintain the machine.

If you are serious about reducing the maintenance and repair of your undercarriage, follow these tips. ●

Visually inspect the machine each day for leaking rollers and track pins.

●

Check and adjust the track tension on a regular basis, especially as job and soil conditions change.

●

Keep the tracks as clean as possible. Packing materials and abrasives will both accelerate the wear process.

●

Check for loose or missing hardware on a regular basis and replace all missing or damaged parts.

Tighten all bolts to the recommended specifications.

●

When possible, work up and down a slope instead of across it. This decreases wear on roller flanges and link side rails.

●

Tracks that are too tight rob power and cause early bushing and sprocket wear. Periodically check tracks for correct tension.

●

Check track tension and clean the undercarriage more frequently when working in high packing conditions.

●

Use the smallest track shoes possible to minimize track chain twisting. Limit the use of wide track shoes to high flotation applications.

●

Park the machine on level ground to prevent seal distortion (Case Lubricated Track and Case Extended Life Track).

●

Turn the pins and bushings at the 100% wear limit.

Operating past the 100% wear limit can cause the bushings to crack or to wear completely through to the pin.

●

Letting the pins and bushings run to destruction results in accelerated wear of other components. Turn the pins and bushings to extend track life.

●

Speed, impact, turning and direction of operation greatly affect wear.

●

Avoid high speed operation whenever possible, particularly in rough terrain.

●

Avoid spinning the tracks as much as possible, especially in abrasive soil conditions.

●

Do not spin or slide the tracks. Apply the power and stop the machine gradually.

●

If possible, avoid reverse operation, especially high speed reverse operation.

●

Avoid long runs at high speed and limit the amount of reverse travel.

SPROCKET WEAR AND MEASUREMENT Sprocket tooth wear is the most obvious of all wear patterns. Track bushing wear is not as obvious but still must be considered when evaluating corrective action.

Clean Track When the undercarriage is clean, each bushing seats against a sprocket tooth. The bushing is engaged at the 6 o’clock position and carries approximately 85% of the driving load. At 5 o’clock the load is reduced on this bushing to 10% and at 4 o’clock down to 5% of the drive load.

SPROCKET BEGINS TO PACK A material begins to pack into the sprocket teeth, the bushing must be engaged at a higher position on the tooth. See the following illustration. The first bushing will be seated against a tooth and there will be a space between the next bushing and tooth. As the sprocket rotates, each bushing that is to be engaged will be progressively further from the driving tooth.

The first bushing continues to receive the full load as the sprocket rotates. When this bushing leaves the sprocket, the track chain will re-seat on the sprocket. This reseating results in the bushing impacting against the sprocket tooth. At the same time, the increased track tension causes the track recoil spring to be compressed.

As the bushing re-seats, the impact of the bushing along with the release of the recoil spring causes a loud “banging” noise.

Bur 7-10142NA

When severe packing occurs, bushing engagement starts much later in the sprocket rotation, around 1 to 2 o’clock. The chain pitch is increased to the maximum. As a result, (1) the chain is tightened, (2) the recoil spring is compressed and, (3) bushing engagement moves out to the tip of the sprocket tooth. The driven bushing continues to receive full load until this bushing leaves the sprocket tooth. At that time the track chain seats again on the sprocket. At the same time, the recoil spring is released against the stop and a loud noise is heard.

This severe packing condition can also cause the chain bushing to climb up and go over the top of the sprocket tooth. This condition, called jumping, will also cause a loud noise.

The best action to take is to loosen the tracks to the correct tension. Or, you can install special relieved drive sprockets if the packing material is extrudable. The special relieved drive sprockets will help to clean material from the sprocket root.

NOTE: Special relieved drive sprockets can reduce the life of the track chain bushings as there is less contact area on the sprocket.

All Case Sealed and the Case Lubricated track (C.L.T) chains use a “hunting-tooth” design drive sprocket with an odd number of teeth. This design causes each tooth to make contact on every other revolution. We use the same sprocket for non-lubricated track as well as the Case lubricated track.

SPROCKET REVERSE DRIVE SIDE WEAR (MACHINE TRAVELING IN REVERSE)

SPROCKET FORWARD OPERATION WEAR (MACHINE TRAVELING FORWARD)

Reverse drive side wear can be the most severe wear you can have with the sprocket teeth and bushings.

When moving in reverse, the sprocket teeth contact the chain bushings at about 12 o’clock. Most of the torque required to move the machine is transferred to the track chain between 12 and 11 o’clock. During this time, the bushing is rotating against the sprocket. A pocket forms on the reverse side of the sprocket tooth where the rotating bushing is making contact. This contact causes accelerated wear, especially when the machine is moving at high speed.

When driving forward, the sprocket teeth contact the bushings at about 6 o’clock. Most of the torque required to move the machine occurs at this point. The bushing does not rotate against the sprocket until leaving the sprocket at about 11 to 12 o’clock.This is normally not a critical wear factor because the torque was transmitted at the 6 o’clock position. It becomes a problem only when track tension is too tight.

SPROCKET ROOT WEAR (VERTICAL WEAR)

Measuring Sprocket Wear

This type of wear occurs as the track bushings slide through the sprocket root. Accelerated wear occurs with frequent forward and reverse shifting. This moves the bushing back and forth between the sprocket teeth, though wear is even greater if track tension is too tight.

This type of wear is also called vertical wear.

The purpose of this section is to help you measure the wear of undercarriage components as accurately as possible.

Also, by measuring wear and using the charts that are available for your machine, you will be able to determine the remaining life of all the components.

SPROCKET WEAR Sprocket tooth wear is not measurable. The sprocket teeth have no clear reference point from which to take a measurement. The wear on the sprocket teeth is due to (1) the contact with the track chain bushings and (2) any material trapped (packed) between the components. As the components wear, certain wear patterns develop on the sprockets.

A visual examination of the sprocket teeth along with the bushing outside diameter measurements will give you a good idea of the sprocket condition.

BUSHING WEAR Bushing Off-Center Wear

Bushing Reverse Drive Side Wear

This type of wear is caused by misalignment of any of the undercarriage components. The track chain is pushed against the side of the rollers or idler flanges or against the side of the sprocket. Off-center wear is also caused by continuous side hill operation. If you must operate the machine sideways on a hill, operate in both directions. If side hill operation is unavoidable, changing component parts from side to side will lengthen undercarriage life.

The use of rock guards/track guides also help to maintain alignment.

Reverse drive side wear can be caused by sprocket reverse tip wear or machine reverse travel, see page 15, Sprocket Reverse Tip Wear or Sprocket Reverse Drive Side Wear. Reverse drive side wear is a major wear pattern for bushings in all track chains and is accelerated with tight track and high speed reverse operation.

Bushing Forward Wear Forward wear is the normal wear which occurs as the machine is driven forward, see page 15. Forward drive side wear will generally show less wear than reverse or vertical wear because of the lack of bushing rotational movement when the machine is driven forward.

UNDERCARRIAGE COMPONENTS AND WEAR

Bushing Cracks (Non-Lubricated Track)

Pins and Bushings (Pitch Extension)

Excessive external bushing wear with excessive internal wear will cause thin bushing sides, reducing the bushing strength. Impact loads can then cause cracks in the bushings.

To measure the internal bushing and pin wear, measure the track pitch in three places on each track. This measurement is the distance between five track pins.

Make sure the measurement is taken at least four track links away from the master pin (non-lubricated track).

The master pin has a hole in each end. Tighten the track to remove all slack and measure from the front of one pin to the front of the 5th pin. See the following illustration.

Make a record of the measurements on the Track Component Appraisal Form.

Bushing Cracks (Case Lubricated Track) Excessive external bushing wear and high impact loads will cause the bushings to crack. Prevent this problem by turning the pins and bushings at the recommended time.

See page 17 for Wear Measurements.

Bushing cracks can also result when you run the undercarriage to destruction. When this happens, you prevent the possibility of turning the pins and bushings (sealed and C.LT.).

IMPORTANT: The Case lubricated track will have little pitch wear unless the seals are damaged and the lubricant lost in individual joints. The dry joint will feel hot after operation.

Prevent this problem by performing wear measurements and turning the pins and bushings at the recommended time. See page 38 for instructions to measure the undercarriage system (sealed and C.L.T.).

TRACK PIN WEAR Pin Surface Wear

Pins Breaking

B912308 B912305

NON -LU BRIC ATED TR ACK - Track pin wea r is accelerated by tight track, high speed operation, and abrasives between the pins and bushings. As the tracks turn around the sprocket and idler, the pins and bushings pivot internally. This pivoting action wears the outside surface of the pins and the inside surface of the bushings. But, because the chain is under tension, this wear occurs only on one side of the pins and bushings (regardless of forward or reverse direction of the tracks).

The pin and bushing wear, called “pitch wear”, eventually increases the length of the chain.

CASE LUBRICATED TRACK AND CASE EXTENDED LIFE TRACK - This condition can be caused by tight track, high impact loads, severe packing, and using track shoes that are too wide. This problem can also be caused by not installing the pins correctly at assembly.

Cracks start at the outer surface at the reservoir hole and spread through the pin at a rapid rate. This condition is not common with sealed track pins.

Pin End Wear

B912309

B912306

CASE LUBRICATED TRACK AND CASE EXTENDED LIFE TRACK - Track pin wear is greatly reduced with the C.L.T. and C.E.L.T. However, tight tracks with high speed operation, operating in packing conditions, or using track shoes that are too wide will cause the pins to gall (score marks on the surface).

Pin end wear is caused by misalignment, track shoes that are too wide, worn idlers or worn roller flanges. This condition can also result from hillside operation. The pin ends rub against the track guides/rock guards.

Pin Spalling

B912307

CASE LUBRICATED TRACK AND CASE EXTENDED LIFE TRACK - If you operate the machine with tight tracks, heavy packing, or flexing of the chain caused by shoes that are too wide, cracks can begin to form at the oil reservoir hole and spread out.

UNDERCARRIAGE COMPONENTS AND WEAR

TRACK LINK WEAR Link Uneven Top Wear

Wear on the inside surface of the link is caused by rotating contact with the next link when seal failure occurs. Bushing end wear and lack of link separation occurs. If the link rails are not worn excessively, turn the pins and bushings and reseal.

Pin Boss Top Wear

B900597

This wear is caused by contact with the roller flanges due to link rail surface wear and roller tread surface wear.

This condition must be corrected or track chain rebuild will not be possible. Your machine will start to vibrate.

As the tracks rotate, the rail surfaces of the link contact the idler, rollers and carrier rollers. The wear pattern that develops eventually becomes “wavy” or “scalloped”. See the illustration that follows. These wear patterns are normal.

The forward and rearward surfaces wear faster because of the narrow link overlap. The center wear surface is sliding wear due to a reduced contact area with the idler wheel.

B900599

Side Wear of the Link Rail

Sprocket Wear on the Inside of the Links

B900598

This wear occurs because of contact with the rollers and idler flanges. Wear increases with side hill operation, turning, uneven terrain, misalignment or track shoes that are too wide. Looseness due to increased track pitch (bushing to pin wear) allows the track chain to flex from side to side increasing side loads and side wear.

B900600

The following illustration shows wear caused by the tips of the sprocket teeth on the inside of the link. This occurs due to misalignment between the sprocket and rear roller. Other causes can be a chain that has worn pins and bushings, side hill operation or track shoes that are too wide.

Counterbore Extension of the Link

B921123 B912310

This wear is caused by the same condition as was stated under Wear on the Inside Surface of the Link - wear caused by rotating contact with the next link when seal failure occurs. Bushing end wear and lack of link separation occurs. Other kinds of causes can be side hill operation, turning and high impact.

This condition is caused by seal failure that causes the bushing to rotate in the bore. This is a direct result of pitch extension and usually occurs after the pins and bushings have been turned. Track shoes that are too wide can also cause this condition.

Link Crack

Link Rail Spalling

B900601

B912311J

This condition occurs with repeated high impact loading with the track rollers. Machine speed, weight, tracks that are too tight, or track shoes that are too wide can also cause the problem. If the area of damage is over 25 to 30%, wear life and rebuildability may be reduced.

Link cracking is caused by twisting track chain. This is usually caused by track shoes that are too wide, high impact, or tight tracks. If you see this type of damage, replace the links immediately to prevent further damage.

Pin Boss End Wear of the Link

B912312

Wear of the pin boss is caused by sliding contact with the track guides/rock guards. This condition is caused by side hill operation or track shoes that are too wide.

IDLER WEAR Idler Tread Surface Wear

Idlers

Normal wear occurs between the tread surface and track lin ks. Acce le ratio n o f this we a r ca n o ccu r w ith applications that put more weight on the idlers, speed, high impact, turning, tight tracks, packing and abrasive soils.

The only wear that can be measured on the idlers is the treads. This wear is normal and is caused by the track links moving around the idler. Assemble the rules in the kit to make a depth gauge. See the following illustration.

Make sure the treads are clean. Measure the center of the treads because this is the area of greatest wear.

Measure both sides of the idler. Make a record of the idler measurements on the Track Component Appraisal Form.

B912318

Idler Flange Side Wear This wear is caused by contact with the inner rail of the track links. Misalignment, side hill operation, excessive turning, tight track, worn track guides/rock guards, and track shoes that are too tight all contribute to this wear.

TRACK ROLLER AND TRACK CARRIER ROLLER WEAR Rollers will show wear on the tread surfaces and the sides of the flanges. These are normal wear patterns caused by contact with the track chain links.

Tread Wear Wear will occur between the tread surface (1) and the top of th e tra ck link ra ils. This we ar is no r ma l a nd unavoidable. However, this wear is accelerated by high speeds, impact loads due to rough terrain, packing, and the use of track shoes that are too wide. When packing prevents the roller from turning, flat spots on the tread surface will occur.

Flange Wear

Track Rollers and Carrier Rollers The only wear that can be measured on these rollers is the treads. Use the large caliper from the kit and measure both treads of each roller. If required, remove the rock guards/track guides. When installing the rock guards/track guides, use Loctite 242 on the threads of the mounting bolts. When the middle track rollers are 40% worn, it is recommended that the track rollers be rotated. Make a record of the roller measurements on the Track Component Appraisal Form.

Make sure that you hold the caliper in the center of the treads as this is the area of most wear. Care must be taken to find the smallest worn diameter. Measure both treads of each roller.

Wear on the flange tops (2) shows that the roller treads and/or the link rails are worn past the wear limits. The flanges are contacting the link pin bosses. Side flange wear (3) shows misalignment, side hill operation, excessive turning, worn track, or track.

UNDERCARRIAGE COMPONENTS AND WEAR

TRACK SHOE WEAR Track Shoes The wear that is measured on the track shoes is the height of the grouser. There are three types of track shoes (1) one bar, (2) two bar, or (3) three bar grouser.

Assemble the rulers in the kit to make a depth gauge. If your machine has single bar grousers, tighten the track chain before measuring. Refer to the following illustration and measure several track shoes on each side of the machine. Measure the wear 1/3 the distance from the outer end of the track shoe. Make a record of the measurements on the Track Component Appraisal Form.

When finished, adjust the track for correct tension.

B900612

Cracked or Broken Shoes Cracked or broken shoes can be caused by various conditions. Some of the causes can be terrain, impact loads, speed, shoes that are too wide for the conditions, or structural problems for a track shoe that has lost most of the grouser bar/s. Always try to use the narrowest track shoe possible.

B900611

Grouser Wear The following illustration shows wear of the grouser. This wear is normal and unavoidable. The greatest cause of grouser wear is track slipping. This is non-productive and can be controlled by reducing track speed and using the correct type track shoe for the job. Excessive wear of the grousers will reduce the strength of the track shoes increasing the probability of track shoe bending.

B900613

Bolt Holes Too Large If the mounting bolts are loose, the bolt holes can become larger. If this happens, the track shoes and mounting hardware must be replaced. Conditions that cause hardware to loosen can be (1) hardware that was not torqued correctly, (2) track shoes that are too wide, or (3) turning resistance in rocky terrain.

When installing new track shoes, links, and hardware, always clean the mating surface of all paint, rust and dirt.

Always use the recommended bolt torque. (Don’t over torque.)

B912322

Wear on the corners of the grousers usually indicates rough terrain with high impact conditions. If the shoes are too wide, the corners can chip or bend.

CASE NON-LUBRICATED TRACK Case Lubricated Track (C.L.T.) and the Case Extended Life Track (C.E.L.T.) provide substantially more service life than the sealed track or non-lubricated track.

Because of the greatly reduced internal wear of the (C.L.T. & C.E.L.T.) pins and bushings, the wear patterns of the undercarriage will be somewhat different from those of the sealed track.

Turning Pins and Bushings (Non-Lubricated Track) Turning the pin/bushing assembly in the track link returns the track chain to the original length and puts fresh bushing material in contact with the sprocket teeth.

This track is assembled with pins, bushings and Belleville seals on each side to reduce the amount of dirt entering the bushings. Parts are lubricated at assembly.

UNDERCARRIAGE COMPONENTS AND WEAR

CASE LUBRICATED TRACK (C.L.T.) The Case lubricated track design begins with a link joint that seals out abrasives and keeps the lubricant in. Pin and internal bushing wear is virtually eliminated by constant lubrication from the oil reservoir in each pin.

External bushing life is also extended due to a larger bushing outer diameter and deeper case hardening.

DRY TURN - A dry turn can be made when the pins, bushings, and seals are in condition to be used again but not good enough to be used as a sealed assembly. Lubricant is not added to this joint after turning. See the service manual for your machine for more information.

Sealed and lubricated pins and bushings means less track friction. The machine actually has more horsepower available for machine work.

IMPORTANT: If hollow pins are used in a dry turn, make sure the lubrication hole is put in the vertical position and the oil passage hole is toward the link rail wear surface. Installing the pin wrong can cause the pin to break.

3

IMPORTANT: After turning the pins and bushings, it is recommended that you use new track shoe mounting bolts. Be sure to torque bolts as specified and recheck bolt torque daily until they stabilize. (Don’t over torque.)

Marking the Pins and Bushings (Case Lubricated Track) 4

Before you turn the pins and bushings, mark each pin and bushing with a little paint as shown below. This will give good identification reference points as you reassemble the track chain.

Turning Pins and Bushings (Case Lubricated Track)

CASE lubricated track has virtually eliminated internal pin and bushing wear. Only the outer bushing to sprocket wear is the main concern. This track system is very dependent on the seals. If a joint fails and loses oil, that joint will wear rapidly.

Bolt-on sprocket segments or new sprockets must be installed when you turn the pins and bushings. The bushings in the newly restored track chain will continue to ride high on the worn sprocket teeth causing faster wear.

Because there is virtually no internal wear of the pins and bushings with this type of track, measure the outside wear of the bushings. If the bushings are turned, it is recommended that you replace both drive sprockets at the same time.

WET TURN - A wet turn can be made when the pins, bushings and seals are in condition to be used again to make a sealed and lubricated joint. Refer to service manual for your machine for more information.

CASE EXTENDED LIFE TRACK (C.E.L.T.) The Case extended life track (C.E.L.T.) is a sealed and lubricated track and incorporates a large diameter bushing that is free to rotate on the standard track bushing. This allows wear to be distributed over the entire circumference of the bushing and because it is free to rotate, it does not create the scrubbing wear between the sprocket and the bushing as the conventional track does.

The Case Extended Life Track provides the long service life that the Case Lubricated Track provides with the internal lubrication. It also provides up to twice the bushing wear life on the external surface of the bushing, because of the rotating bushing and greater wear material.

The rotating bushing can make a clanging noise “when worn” during Hi speed operation. The bushing will make less noise when crawler is dozing.

Bushing and Sprocket Wear Chart

The life of the Case Lubricated Track, the Case Extended Life Track and the non-lubricated track is directly controlled by track tension. This single factor is the most important in controlling the track life.

The tighter you have the tracks, the faster the wear. The following chart illustrates the relationship between wear rate and track sag.

Other Conditions

NOTE: It is recommended that you turn the pins and bushings at the 100% wear limit, or before.

If the Case Lubricated Track or the Case Extended Life Track does not show improved life when compared with the non-lubricated track, one or more of the following conditions has occurred: 1. The track tension was too tight.

2. The track pins lost lubricant. This can be caused by having track shoes that are too wide for the conditions or by high impact conditions.

3. Soil or operating conditions have changed.

Correct Tension Correct track adjustment is the most important factor that helps to control undercarriage wear. Track sag of 11/2 to 2 inches must be maintained for all Case crawlers.

IMPORTANT: When operating in packing conditions (mud, snow, etc.) material will stick to the track parts and cause the track tension to be too tight. Check and adjust the track tension often during these conditions.

CASE RUBBER TRACK The Case rubber track is only used on the Model 550G Crawler. The basic structure of the Case rubber track is composed of steel cords and metal embedded in rubber.

6. GROUSER LUG

Rubber tracks cause less damage than steel tracks to fields and roads and less rutting of soft ground than steel tracks. The tracks insulate machinery and the operator from vibration, resulting in longer machine life and lower operator fatigue. Less noise is also generated from a rubber track.

While rubber track causes less disruption to the job site, it should not be used in forestry, logging or in rocky conditions where rocks are greater than 2 inches in diameter.

EXTENDING RUBBER TRACK LIFE ●

Avoid sharp projections when maneuvering.

●

Usage on rock up to 1-1/2 to 2 inches diameter is permissible.

●

Avoid driving with rubber track edge against walls, concrete, or hard surfaces that may cause rubber scuffing, tearing, or cracking.

●

Monitor track tension to prevent detracting.

●

Operating temperatures -15° to +130° F.

●

Call the dealer if you experience any problems with the machine or the track system.

●

Do not use in larger rock, stump removal, or land clearing applications.

●

On the question “Is this an application for the rubber track?” you can answer that by asking yourself, “Would I expose a rubber tired unit to these conditions?”. If not, do not use the rubber track in that application. If yes, proceed, but use common sense.

1. Tension of rubber track, see Service Manual.

A. Reference Attachment III for proper tension of 0 to 1/2 inches (0 to 12.7 mm). When operation on hillsides or side slope condition s, it is recommended to maintain tension at 0 to 1/4 inch (0 to 6 mm). Remember excessive tension can rob horsepower or cause track breakage.

B. When the track tension decreases, it should be readjusted because the rubber track may come off. Track sag must be checked daily, or as required when operation conditions warrant checking.

2. Attention when operating. Sharp objects can cut the track. Be careful when operating the machine on rocks and other shar p objects to prevent damage to the track. Avoid contact with concrete sharp edges, ridges, and keep edge of track from riding on or against a curb or side of a concrete wall.

3. Avoid quick turning. Turning too fast on concrete roa ds, sh ar p p ro je ctio ns, or oth er a bra sive materials which have a high coefficient of friction should be avoided because of cutting the rubber track may occur.

4. Prevent oil contamination. If fuel or oil comes in contact with the rubber track, wipe or wash the tracks as soon as possible to keep the rubber track from becoming damaged.

5. Prevent salty contaminations. Use in a coastal or similar environment should be avoided when the rubber track has been cut or otherwise exposed the core metal because salt and salty air erodes the adhesion of the rubber to the core metals.

Wash tracks regularly if working in salt, chemicals, fertilizer, or acidic soils.

Bur 7-10142NA

6. Storage. When the machine is not used for long periods of time, park the machine inside a building or cover the tracks to prevent damage by the sun and weather. Move the machine once a month, rotating the tracks and stopping so the hinge points that were at the idler and sprockets are in a flat position.

7. Sprocket replacement. When the new rubber tracks are installed. Rollers and idler wear should also be checked. Special care is required in handling the track.

8. Operational temperature. Temperatures affect the operation of the tracks. Operate the machine in temperatures between -15° to +130° F (-25° to 55° C).

Causes of Damage to Rubber Track and Counter Measures 1. Structure of Rubber Track. The steel cord and metal are molded in rubber. Lugs provide the traction. Special track guides and high flange idlers are on the machine to prevent the track from coming off during side hill or slope work operation.

2. Causes of damage. ● Breakage of steel cords when stones or foreign materials lodge in the rubber track undercarriage. ● Breakage of steel cords when the track comes off. ● Breakage of steel cords when the track partially detracts and interferes with track guides, idler, or sprocket. ● Breakage of steel cords when the track is over-tensioned.

Counter measures ● Maintain correct track tension. ● Avoid aggressive turns on rough ground (sharp breaking turns). ● Keep hard obstacles out of track system. ● Do not drive on sharp material ground (rocks, debris, stumps).

3. Abrasion and breakage of the core metals.

A. Similar to the breakage of steel cords mentioned above, excessive tension may cause core metals to be broken. Abrasion caused by one of the following may also cause core metals to be broken. ● Mis-engagement between sprocket and rubber track bushing or drive lug. ● Operation on sandy ground (packing condition).

Issued 04-05

Printed in U.S.A.

UNDERCARRIAGE COMPONENTS AND WEAR 4. Separation of core metals.

A. The core metal is retained by the adhesion of rubber, especially between the core metal and steel cords. Separation can be caused by excessive backward bending and/or semidetracking.

B. The core metal can be corroded by severe environment. The adhesive system wou ld deteriorate due to progress of the corrosion and the core metal will separate from the track. This could happen during the following conditions: ● Salty environment, such as coastal area. ● Active chemical environment. ● Fertilizer Counter measures ● Thoroughly wash the track after above exposure 5. Fatigue cracking or abrasion. ● Crack on foot of lug. ● Cracking occurs at the foot of the lug due to the bending fatigue of rubber caused by sprocket and idler.

Counter measures ● Avoid “ozone” environment such as direct sunshine and heavy traffic. ● Move the machine and rotate the track once a month. ● Avoid getting lug cut damage from sharp objects.

6. Crack on edge of rubber. ● The bending of the edges can cause cracking of the rubber.

Counter measures ● Avoid driving with the rubber track coming into contact with concrete edges, etc. ● Avoid driving in rough material conditions.

Bur 7-10142NA

1-33

7. Abrasion of lug. ● Rubber abrasion may be caused when turning on a concrete surface or hard road surface.

Counter measures ● Avoid rapid or abrasive concrete or sharp material. ● Avoid spinning tracks.

Suggestion of replacement of rubber track. ● The damage conditions mentioned above are not considered fatal, although gradually progressive damage may occur. It can still be usable, however. ● The damage discussed above gradually progresses to a terminal state causing the core metal to be exposed. The exposure of core metals along more than half the circumference of the rubber track indicates that it is time for the rubber track to be replaced. It can still be usable, however. ● With regard to abrasion as discussed above, remaining lug height of only about 5 mm is an indication that the rubber track should be replaced. It can still be considered usable, however.

8. Cracking due to external factors. ● Crushed stone, gravel, or sharp material such as steel plates, nails, or glass very often cause cracking or cuts in the outer face of the rubber track (the side in contact with the ground).

Operating conditions should be checked frequently during usage.

Counter measures ● Maintain proper rubber track tension with automatic track tensioner.

Avoid semi-detracting or detracting.

Measure grouser lug wear as shown. Percent worn values are: New = 50 mm (1.97 inch) 25% worn = 40 mm (1.57 inch) 50% worn = 30 mm (1.18 inch) 75% worn = 20 mm (.79 inch) 100% worn = 10 mm (.39 inch)

BD98G006

Record projection guide wear in relationship to nonwearing surface of rubber track. The new (unworn) projection guide height is 37.5 mm (1.48 inch).

33.9 1.1 mm

Since the projection guide is worn 1.6 mm you must add 1.6 mm and 1.1 mm to get total drive lug vertical wear.

(2.7 mm Total Wear)

From the previous measurements you have determined vertical drive lug wear to be 2.7 mm. Record the 2.7 mm on the full scale drawing by marking an “X” as shown.

Because of the construction of rubber track it is difficult to obtain exact forward/reverse drive wear measurements.

BD98G009

Position the contour gauge over the full scale drive lug drawing so the vertical wear on the contour gauge is located at the 2.7 mm wear mark. Trace the profile.

BD98G004

For an estimated wear value you can take the profile of the drive lug using a contour gauge.

The profile is then traced on a full scale drawing on the drive lug so wear value can be estimated.
