This is an idler, a crucial component in the undercarriage system of Volvo compact excavators, designed to guide and maintain tension on the track. It is manufactured to withstand the abrasive conditions and heavy loads encountered in excavation work, ensuring proper track alignment and performance. Operators may observe excessive track slack, premature track wear, or unusual noises from the undercarriage when an idler begins to fail.

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.
Early signs of idler failure include increased noise from the undercarriage, such as grinding or squealing, and noticeable looseness in the track. If left unaddressed, the idler can seize or break, leading to the track derailing. A derailed track can cause significant damage to the undercarriage components and result in extended downtime.
Ensure the mounting surface and shaft are clean and free of debris before installing the new idler. Do not overtighten the mounting bolts, as this can damage the threads or the idler housing.
Inspect the track chains, rollers, and sprockets for wear and damage when replacing the idler, as these components work together.
