Undercarriage Parts v2

Sprockets - Specifically designed to provide the maximum reliability and performance, drive sprockets especially should be replaced at the same time as new rubber tracks are fitted.

Idlers - These tension the rubber track and guide it around the front of the track undercarriage. If worn they can cause a rubber track to come off the frame continually, leading to potentially serious damage.

Top Rollers (carrier) - Often not fitted to the smallest mini-excavators, top rollers serve the purpose of guiding the rubber track over the undercarriage frame. They also need to be replaced once worn.

Bottom Rollers (tracks) - Designed, engineered and manufactured for applications requiring high load resistance, track rollers carry the brunt of an excavator’s weight. They should ideally be changed as a complete set, and not individually, in order to ensure that the machine’s weight remains evenly distributed.
