This sprocket is a crucial drive component in the undercarriage of Volvo excavators, engaging with the track chain to propel the machine. Manufactured from hardened, wear-resistant steel, it provides reliable power transfer and longevity under demanding conditions, unlike a worn sprocket with rounded teeth that can cause track derailment. Operators may notice increased track noise, accelerated track wear, or the track slipping off the sprocket if it is damaged.

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.
The first indication of a worn drive sprocket is often an increase in noise from the undercarriage, particularly during turns, and visible wear on the sprocket teeth. If ignored, the worn teeth can lead to premature wear of the track chain and rollers, and eventually cause the track to derail. The most serious consequence is a complete track loss, leading to significant downtime and potential damage to other undercarriage components.
Ensure the final drive hub and mounting bolts are clean and in good condition before installing the new sprocket. Always torque the mounting bolts to the manufacturer's specifications in a star pattern to ensure even seating.
Inspect the track chain, rollers, and idlers for wear and damage when replacing the drive sprocket.
