3985218 Track Roller — Volvo FH12 FH16

This track roller supports the weight of the machine and guides the track chain on the undercarriage, crucial for smooth movement and preventing track derailment. Manufactured from hardened forged steel, it offers superior wear resistance compared to a worn or seized roller that can cause excessive track wear. Operators will typically observe increased vibration, abnormal track noise, or a noticeable wobble in the track when a track roller begins to fail.

Failure Symptoms

A failing track roller may initially cause a grinding noise or increased vibration felt through the machine's cab. If ignored, the roller can seize, leading to rapid track chain wear and potential derailment. A seized roller poses a significant risk of damaging other undercarriage components and causing extended downtime.

Installation Tip

Clean the mounting surfaces and bolt holes thoroughly before installing the new roller to ensure a secure fit. Avoid using excessive force or hammering to seat the roller, as this can damage the bearing seals.

Service Note

Inspect the track chain for wear and proper tension, and check the idler and sprocket for damage when replacing track rollers.
