Failure Symptoms

Initial signs of failure may include unusual noises emanating from the undercarriage or a noticeable looseness in the track system. If left unaddressed, this can lead to accelerated wear on adjacent components and potential track derailment. Continued operation with a failing component risks significant downtime and costly repairs to the entire undercarriage.

Installation Tip

Ensure the track is properly de-tensioned before attempting removal to avoid injury and damage. Do not overtighten mounting hardware, as this can distort the component or damage mounting surfaces.

Service Note

Inspect track chains, rollers, and idlers for wear and damage when replacing this undercarriage component.
