Failure Symptoms

Initial signs of failure may include grinding noises during operation or a slight hesitation in track movement. If left unaddressed, the gear teeth can wear down further, leading to intermittent track slippage or complete loss of drive power. Continued operation with a failing gear can cause damage to the final drive and track components.

Installation Tip

Ensure the final drive housing is thoroughly cleaned of all old lubricant and debris before installing the new gear assembly. Avoid overtightening the mounting bolts, as this can distort the housing or damage the gear teeth.

Service Note

Inspect the track sprocket and final drive bearings for wear or damage when replacing the drive gear assembly.
