102-8076-1028076 Carrier Roller 102 8076 — Cat 3054 307

This carrier roller is a crucial suspension component that supports the weight of the track on one side, ensuring smooth movement and proper track alignment. Manufactured to meet demanding OEM specifications, it offers superior load-bearing capacity and wear resistance compared to a worn roller with a damaged seal or flat spots on the tread. Operators may notice increased vibration, unusual track noise, or a tendency for the track to derail if this component begins to fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early signs of carrier roller failure often include increased noise from the undercarriage, such as grinding or squealing, and noticeable vibration transmitted to the operator's cab. If left unaddressed, the roller can seize or break apart, potentially causing the track to derail, leading to significant downtime and damage to other undercarriage components. The most severe outcome is catastrophic undercarriage damage and loss of machine mobility.

Installation Tip

Ensure the mounting surface on the track frame is clean and free of debris before installing the new roller to guarantee proper alignment and sealing. Avoid using excessive force to seat the roller, as this may damage the mounting points or the roller itself.

Service Note

Inspect the track chain, idler, and drive sprocket for excessive wear or damage that may have contributed to the carrier roller's failure.
