Product Overview
Clunking, a track that rides unevenly, visible flat spots, side-to-side roller play or a lower roller that no longer turns freely can put extra load on the rest of the undercarriage. Worn rollers can also accelerate track and sprocket wear if the machine continues to work with poor support along the lower track run.
This replacement bottom roller restores one of the primary support points carrying the excavator on its track. It is the appropriate repair when the original roller is seized, leaking or worn beyond service limits and the surrounding undercarriage components are still serviceable.
