Failure Symptoms

Initial symptoms of a failing track roller may include a distinct clanking sound as the track passes over it, or increased vibration felt through the operator's station. If ignored, the roller's bearing seal can fail, leading to contamination and rapid internal wear, which can cause the roller to seize. A seized roller can damage the track chain and significantly impede machine mobility.

Installation Tip

Ensure the mounting surface on the track frame is clean and free of debris, and that the bolt holes are not damaged. Avoid using excessive force when tightening mounting bolts, as this can strip threads or damage the roller assembly.

Service Note

Inspect the track links, pins, and bushings for wear and damage when replacing track rollers.
