This 19-tooth drive sprocket is a crucial element of the undercarriage system, engaging with the track chain to propel the excavator.

Failure Symptoms

The first sign of a worn drive sprocket is often a noticeable increase in track noise or a feeling of 'jerky' movement when accelerating or turning. If left unaddressed, the worn teeth can cause the track chain to slip or become unevenly stretched. Continued operation risks premature wear on the track chain and potential damage to the final drive.

Installation Tip

Ensure the mating surfaces on the final drive and the sprocket are perfectly clean to achieve a flush fit and prevent leaks. Do not reuse old mounting bolts; always use new hardware to ensure secure attachment.

Service Note

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