This Undercarriage Reconditioning Bulletin contains the necessary information to allow a dealer to establish a parts reusability program. Reuse and salvage information enables Caterpillar dealers and customers to benefit from cost reductions. Every effort has been made to provide the most current information that is known to Caterpillar. Continuing improvement and advancement of product design might have caused changes to your product which are not included in this publication. This Undercarriage Reconditioning Bulletin must be used with the latest technical information that is available from Caterpillar.
For technical questions when using this document, work with your Dealer Technical Communicator (TC).
To report suspected errors, inaccuracies, or suggestions regarding the document, submit a form for feedback in the Service Information System (SIS Web) interface.
Summary
The following information is given to provide Disassembly and Assembly procedures for idlers with conventional Duo-Cone seals. The information in this bulletin should serve as an aid in determining whether an idler with conventional Duo-Cone seals can be reconditioned. During rebuild procedures, always correct any conditions which may have caused the original failure or wear.

Safety
Illustration 1 | g02139237 |
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 identify 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.
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. |
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. |
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. |
Canceled Part Numbers and Replaced Part Numbers
This document may not include all canceled part numbers and replaced part numbers. Use NPR on SIS for information about canceled part numbers and replaced part numbers. NPR will provide the current part numbers for replaced parts.

Refer to Illustration 13. The clearance may be checked with a 8H-8581 Gage-Feeler or using the dimensions in Table 6 and Table 7.
If the clearance measurements are not acceptable, an evaluation will be necessary to determine the problem. The following procedures can be taken to correct the problem:
- Recondition the existing bearing bore.
- Recondition the bore of the idler and install new bearings.
- Replace idler shaft.
Note: Refer to Undercarriage Reconditioning Bulletin, SEBF8586, "Removal, Installation, and Conditioning of Idler Bearings and Track Roller Bearings".

Note: Always use new O-rings in the retainers and end collars.
Show/hide tableIllustration 18 g01583933 - Inspect each set of Duo-Cone seals for reusability. Refer to Undercarriage Reconditioning Bulletin, SEBF8511, "Reusability Recommendations for Duo-Cone Seals".
Note: If the Duo-Cone seals are reusable, the Duo-Cone seals must be kept in matching pairs.
Show/hide tableNOTICE Misalignments, twists and bulges of the toric ring will cause Duo-Cone seal failures. If any of these occur, perform the assembly process over from the beginning.
- If the Duo-Cone seals are reused, replace the toric rings.
Note: Make sure that the toric ring is not twisted on the seal ring.
- Install the Duo-Cone seal in the proper seal installer. Refer to Table 8 for the correct seal installer.
