This sprocket is a vital component of the undercarriage system, engaging with the track links to propel the Volvo excavator. It is constructed from hardened steel for maximum durability and wear resistance, ensuring reliable power transfer unlike a worn or damaged sprocket. Operators may notice increased track noise, poor track tension, or a rougher ride if this sprocket begins to wear unevenly or break teeth.

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 a worn sprocket include excessive noise from the track system and a tendency for the track to 'climb' or jump off the sprocket. As wear progresses, the sprocket teeth will become noticeably rounded or chipped, leading to poor track tension and inefficient power transfer. Continued operation with a severely worn sprocket can cause premature wear on the track links and potentially lead to track derailment.
Ensure the final drive hub and mounting bolts are clean and free of debris before installing the new sprocket. Tighten the mounting bolts in a star pattern to ensure even seating and prevent distortion.
Inspect the track chains, idlers, and tensioning system for wear and proper function when replacing the drive sprocket.
