This is a robust sprocket designed to engage with a track chain, providing the driving force for compact construction equipment.

Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

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

Failure Symptoms

The first indication of a worn sprocket is often increased noise from the undercarriage, particularly during turns. If ignored, this can lead to premature wear of the track chain and rollers, and eventually, track derailment. Continued operation risks damage to the final drive and other undercarriage components.

Installation Tip

Ensure the final drive output shaft and the sprocket mounting surface are perfectly clean and free of old sealant or debris. Do not overtighten the mounting bolts, as this can warp the sprocket or damage the shaft threads.

Service Note

Inspect the track chain, rollers, and idlers for wear and damage when replacing the drive sprocket.
