11806139 — Track Roller 11806139 For Volvo Excavator Ec45

This track roller is a critical component of the undercarriage system, supporting the weight of the Volvo excavator and guiding the track chain. Manufactured from hardened forged steel, it offers superior wear resistance and load-bearing capacity compared to a worn or damaged roller. Operators may experience increased vibration, unusual noises like grinding or squealing, and premature track wear when a track roller fails.

Failure Symptoms

A failing track roller often first presents as a noticeable increase in vibration transmitted through the machine's cab. This can progress to loud grinding or squealing noises originating from the undercarriage as the bearing wears out. If left unaddressed, a seized or broken roller can cause track derailment, leading to significant downtime and potential damage to other undercarriage components.

Installation Tip

Ensure the mounting surface on the excavator frame is clean and free of debris before installing the new roller. Do not overtighten the mounting bolts, as this can damage the roller's bearing or the frame.

Service Note

Inspect the track chain for wear and proper tension, and check the condition of the idlers and sprockets when replacing track rollers.
