This track roller is a critical component of the undercarriage system, supporting the weight of the excavator and guiding the track chain's movement. Manufactured to meet Volvo's robust standards, it provides smooth rotation and exceptional wear resistance, unlike a worn roller with flat spots or seized bearings. Operators may hear excessive noise from the undercarriage, experience rougher travel, or notice accelerated wear on the track chain and other undercarriage components when a track roller fails.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A failing track roller will initially manifest as increased noise, such as grinding or squealing, from the undercarriage during operation. If left unaddressed, this can lead to rougher machine travel and accelerated wear on the track chain and other undercarriage components. Continued operation with failed rollers risks damaging the entire undercarriage system, leading to significant repair costs and downtime.
Before removing the old roller, thoroughly clean the mounting surface to ensure a good seal and prevent dirt ingress. When installing the new roller, ensure all bolts are tightened evenly to avoid stressing the mounting bracket.
When replacing track rollers, inspect the track chain for wear, check the condition of the idlers and sprockets, and ensure the track tension is correctly set.
