Summary

The Positive Pin Retention Track was developed by Caterpillar to reduce a common cause of loss of lubrication in track joints. Retaining rings are used to lock the track pin and the track links together. Refer to Illustration 1. The retaining ring prevents any motion between the track link and the track pin during machine operation as well as proper end play of the track joint. With proper end play, the seals maintain full compression against the ends of the bushings and the seals retain oil in the cavities of the track joints.

Illustration 1	g01172751
Positive Pin Retention Track

The information in this bulletin describes the tooling that will be used and the required service procedures. Follow each step to ensure that each track joint has minimum end play and maximum service life.

Note: Refer to Undercarriage Reconditioning Bulletin, SEBF8613, "Field Service for Sleeve Bearing Track" to service D11 Sleeve Bearing Track in the field. Sleeve Bearing Track was introduced in 2002on D11 Track-Type Tractors. Sleeve Bearing Track is now standard on the D11. The Positive Pin Retention Track without the sleeve bearing is no longer available for the D11.

A list of important reference and training materials is shown on the next page of this bulletin. The operator of the track press should become familiar with this material for training prior to servicing the Positive Pin Retention Track.

Safety

Illustration 2	g03673682

Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards. This person should also have the necessary training, skills, and tools to perform these functions properly.

This bulletin may contain hazardous steps. A safety alert symbol like the one below is used to call attention to a hazard.

Warning messages identify a specific, imminent, latent, hazard that has a reasonable probability of resulting in personal injury or death if the warning is ignored.

Illustration 3	g03186216
Example warning

Show/hide table

Do not attempt to disassemble or assemble this machine until you read and understand the disassembly and assembly instructions. Improper disassembly and assembly procedures could result in injury or death.

Show/hide table

Inspect all threaded components before use. Damaged threads may fail under hydraulic pressure. Broken threads may release flying objects that are propelled with great force. Personal injury or death can occur if struck by flying objects.

Show/hide table

Do not stand near the hydraulic press while the press is in operation. A component that slips or breaks under pressure may fly into the air with great force. Personal injury or death can occur if struck by flying objects.

Show/hide table

The machine must be on a level, hard surface before a separation of the track is made. Any time a separation of both tracks is made, the machine must have blocks correctly positioned so the machine will not move.

Show/hide table

Personal injury can result from grease under high pressure. The adjuster cylinder for the track is under high hydraulic pressure. Grease under high pressure can cause injury. Do not visually inspect the adjuster to see if grease is released when the valve is opened. Check the rod to see that it moves to the rear into the front support on the track roller frame.

Show/hide table

Keep away from the front of the machine when the track is pushed off the final drive. A minimum distance of 7.6 m (25 ft) is needed in front of the track to permit the track to move out onto the floor.

Canceled Part Numbers and Replaced Part Numbers

16. Use Tooling (J) to spread the adjacent pair of track links and remove the damaged track joint.

17. Remove the thrust rings and remove the retaining rings as each track pin is pressed out of the bore of the track link.

    Note: If the retaining ring does not fall out of the groove on the track link, use a hammer and a chisel to remove the retaining ring. Be careful not to damage the groove of the track link. The angle and depth of the groove are important.

Preparation for Assembly

Note: Assembly which involves track bushings and track links must be done on the track press. Tooling for removal of the bushing in the field is not available. Refer to Undercarriage Reconditioning Bulletin, SEBF8546, "Shop Repair Procedure for Positive Pin Retention Track".

Note: Carefully clean the track pins, bushings, thrust rings, and track links. A cross section of a track joint is shown in Illustration 1 to help the serviceman identify the track components. Inspection of the track components is easier when the track pins are clean. Cleaning the track pins removes any foreign material and contaminated oil.

Note: For current reuse information of the track components, refer to Undercarriage Reconditioning Bulletin, SEBF8558, "Guideline for Reusable Track Parts".

Note: Whenever any track joint is disassembled, always replace the seal with a new seal.

   Post Turn Seals are now available for all D11T/R/N, D11, D10T/R/N, and D10 track link assemblies. These new seals have a smaller diameter than the standard seals. If a bushing has a maximum of 50 percent end grooving and the bushing is being reused, the Post Turn Seal should be used. The Post Turn Seal will contact a new, unworn surface of the bushing which will provide a better reliability of the seal after service. Reference Information Release Memo, PELJ0242, "New D11R/N Post Turn Seals" and Information Release Memo, PELJ0443, "D10R/N and D10 Post Turn Seals" for more information.

   Use the new 241-1854 Seal Installer with the D11T/R/N and D11 Post Turn Seal. Use the new 262-9822 Seal Installer with the D10T/R/N and D10 Post Turn Seal.

   The standard seal is still available for use when the bushings are replaced. If the end grooving exists inside Tooling (CC), the bushing should be replaced. Ignore the shiny band of contact area. Reference Undercarriage Reconditioning Bulletin, SEBF8558, "Guideline for Reusable Track Parts".

14. Lubricate the stopper with a light weight oil and install the stopper in the end of the track pin with Tooling (M).

    Note: The stopper must be installed 7.0 ± 7.0 mm (0.28 ± 0.28 inch) below the surface of the track pin.

    Note: Absorption of the oil by the stopper causes the rubber to swell. Swelling of the stopper locks the stopper in place. Installing all stoppers before inspecting the remaining track components will allow time for the stoppers to swell. The plastic plugs will be installed later.

    Note: The 5130 and 5110 have the Grease Lubricated Track. Therefore, the track pin does not have an oil reservoir.

Assembly of Track

1. Attach a hoist to the new set of track links.

2. Use Tooling (J) to spread the adjacent track links open so the bushing can pass by the seals.
   Show/hide table

   NOTICE
   Maximum care should be used to prevent the bushing from contacting the seal lips as the joint is brought into alignment. The seal lips can be cut as the bushing slides past.

3. Align the bushing with the seals and lower the hoist to position the pairs of track links together.
   Show/hide table

   Illustration 36	g01348286

    (6) Track pin

    Show/hide table

    NOTICE
    When the pin is installed to the correct depth, it will protrude above the spot face on the link surface. The pin projection adapters have the proper pin projection built in and the correct pin projection should occur automatically, provided the tooling is maintained in good condition and all foreign material (burrs and cold-flowed material) is removed from the spot face surfaces on the links. Correct pin projection is necessary to align the retaining ring groove on the pin with the retaining ring ramp in the link. Unless these are in alignment, the ring will not provide the desired retention.

    Show/hide table

    NOTICE
    Make sure the correct hydraulic pressure is used for the assembly procedure. Hydraulic pressure outside the specification will result in poorly assembled joints or joints with excessive end play.

11. Press the track pin into the pin bores of the track link until the track pin is approximately 13.0 mm (0.52 inch) from the spot face of the track link.
    Show/hide table

   NOTICE
   Do not allow a surge of air to enter the track joint and do not use pressure in excess of 138 kPa (20 psi).

2. Fill track joints with oil. Refer to Undercarriage Reconditioning Bulletin, SEBF8577, "Oil Volumes for Track Link Assemblies".

   Note: Caterpillar uses only synthetic oil for filling the track pins. This oil was previously used for arctic applications. This oil is now the standard oil from the factory. This oil is recommended for use at the turn of the bushing or reseal. Refer to Table 14.

   Note: The synthetic oil is available in the following quantities:

3. Use Tooling (N) to install the plastic plug in the rubber stopper.

   Note: Install the tapered end of the plug into the stopper first.

   Note: The plastic plug must protrude 0.0 mm to 5.0 mm (0.00 inch to 0.20 inch) out of the rubber stopper. The plug can vibrate into the cavity of the track pin if the plug is pushed fully into the stopper hole.

Preparation for Installation of the Track Shoes

Illustration 50	g01160153

1. All paint, loose rust, metal debris, and dirt must be removed from the mating surfaces of the track shoes, track bolts, track nuts, the seats of the track nuts, and the track links.

   Remove paint on the mating surfaces of new link assemblies and new track shoes before installation. The correct clamping force cannot be achieved if the paint is not removed. The following methods may be used to remove the paint:

   • Use a sandpaper of 24 grit to remove the paint from the mating surfaces of the track links and track shoes. A light mist of water should be sprayed on the mating surface during sanding. The water will keep the sandpaper clean during sanding.

   • A paint remover may be used to remove the paint from the mating surfaces of the track links and the track shoes. Make sure that the paint remover does not contact the track seal. The paint remover can damage the track seal.

   • Do not use a torch to remove the paint from the mating surfaces of the track links and master track links. The high temperatures can damage to the track seals.

   • Do not drag the track link assembly across the ground to remove the paint from the mating surfaces of the track links. Dragging of the track link assembly may damage to the master track joint and other track components. High spots may be created on the track links. Dragging the track link assembly may cause the track joints to open.

   Note: The track bolts and the threads of the track nuts must be in good condition.

2. Lubricate the threads of the track bolts and lubricate the mating surface of the bolt head with Tooling (U).

3. Clean the teeth of the split master links.

4. Remove dirt, loose rust, and debris from the bolt holes of the master track link.

   Note: Reuse track bolts in good condition and replace damaged track bolts.

6. Place the lower end of the master link in alignment with the upper end of the master link.

   Note: Make sure that the teeth of both ends of the master link are engaged properly with no interference.

   Note: Close one master link so the teeth are in full contact. The other master link should have no more than a 3.2 mm (0.13 inch) gap between the teeth.

7. Place the master shoe in position.

8. Start all four master track bolts by hand.
