This track roller is a critical component of the undercarriage system, supporting the weight of the excavator and guiding the track chain. Manufactured to meet Volvo's robust standards, it provides smooth rotation and durability, unlike a worn or seized roller. Operators may notice increased vibration, unusual noises from the undercarriage, or accelerated track wear.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A worn track roller may initially produce a low grinding or squealing noise as the machine moves. If ignored, the bearing seal can fail, leading to lubricant loss and premature bearing wear, potentially causing the roller to seize. The consequence of a seized roller is rapid track damage, increased stress on other undercarriage components, and potential operational stoppage.
Clean the mounting surfaces thoroughly before installing the new track roller to ensure a proper seal and prevent contamination. Avoid using excessive force when tightening the mounting bolts, as this can damage the threads or the roller housing.
Inspect the track chain for wear, damage, and proper lubrication, and check the condition of the idlers and sprockets when replacing track rollers.
