The standard track rollers can leak during severe applications. The leakage of oil past the metal face seals leads to a track roller that is not lubricated. If the nonlubricated roller goes for a long period of time without becoming detected, the track roller will fail.

This issue can be addressed with an optional single or double flange track roller group that is heavy-duty. The part numbers for the new heavy-duty track rollers are listed below in Table 1:

Refer to the appropriate Disassembly and Assembly manual for removal and installation procedures for the track rollers. Also, refer to Undercarriage Parts Sales Kit, PECP3003 for information on the part numbers and on usage.
