Failure Symptoms

The first sign of a failing pulley is often an audible squealing or grinding noise from the undercarriage. If ignored, the pulley may seize or develop excessive play, leading to track misalignment and accelerated wear on other undercarriage components. Continued operation with a damaged pulley risks track derailment, causing significant downtime and potential damage to surrounding systems.

Installation Tip

Ensure the mounting surface is clean and free of debris before installation to guarantee proper seating. Avoid overtightening the mounting bolts, as this can damage the pulley bearing or the mounting bracket.

Service Note

Inspect the track tensioning system and surrounding idlers for wear or damage when replacing this pulley.
