How much does a complete undercarriage replacement cost for a 20 ton excavator?

Expert_Answer

A complete undercarriage replacement for a 20 ton excavator can vary widely because the final cost depends on the machine brand and model, track type, shoe width, wear pattern, and whether you replace only the worn components or the full system. A full replacement usually includes track chains, rollers, idlers, sprockets, and track shoes, and sometimes tensioners and related hardware. Labor and transport also affect the total. The best way to estimate accurately is to identify the machine model and inspect component wear.
