Failure Symptoms

Initial symptoms of a failing drive sprocket include excessive noise during operation and visible wear on the sprocket teeth. If ignored, this can lead to rapid wear of the track chain and premature failure of the drive sprocket itself. The ultimate consequence is potential track derailment, causing significant downtime and repair costs.

Installation Tip

Ensure the final drive oil is clean and at the correct level before installing the new sprocket to protect its internal components. Do not reuse old hardware; always use new bolts and nuts to secure the sprocket.

Service Note

Inspect track chains and idlers for wear and damage when replacing the drive sprocket.
