This is an Upper Carrier Roller designed for Volvo excavators, providing support and guidance for the track chain on the upper side of the undercarriage. It ensures smooth track movement and reduces wear on the track links and hull, differing from a worn roller by maintaining its proper diameter and bearing integrity. Operators may notice increased track noise, vibration, or uneven track tension when this roller begins to fail.
Always verify with serial number before ordering.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Increased noise and vibration from the track system, particularly when the machine is moving, are common initial symptoms of a failing upper carrier roller. As wear progresses, the roller may seize or become significantly damaged, leading to excessive track slack or derailment. Ignoring these symptoms can cause accelerated wear on other undercarriage components and potentially damage the track frame.
Ensure the mounting surface on the track frame is clean and free of rust or debris before installing the new roller. Do not reuse old mounting hardware; always use new bolts and washers.
Inspect the track chain links and the track frame for any signs of rubbing or damage when replacing the upper carrier roller.
