Product Overview
Clunking, uneven track travel, visible flat spots, looseness or a lower roller that no longer turns freely can put extra load on the track and neighboring undercarriage parts. Continued use with a seized roller can accelerate wear across the track system.
This replacement bottom roller restores one of the lower support points that carries the machine on the track. It is intended for undercarriage repair when the original roller is worn, leaking, loose or seized.
