Failure Symptoms

Initial signs of a failing pulley include unusual grinding noises from the undercarriage and a noticeable looseness in the track. If ignored, the pulley can seize or break, leading to track derailment and potential damage to surrounding components. Continued operation with a compromised pulley risks significant downtime and costly repairs to the undercarriage.

Installation Tip

Ensure the mounting surface is clean and free of debris before installation to prevent premature wear. Avoid overtightening the mounting bolts, as this can damage the pulley bearings or the mounting structure.

Service Note

Always inspect the track chain, idlers, and track rollers for wear and damage when replacing a pulley.
