Why does my track keep coming loose after adjusting?

Expert_Answer

A track that keeps coming loose after adjustment usually means the underlying cause is not just low tension. Common reasons include a worn or leaking recoil spring, faulty grease cylinder or check valve, worn front idler or bushings, stretched track chain, damaged track shoes, or heavy material packed in the undercarriage. Incorrect adjustment method can also leave the track too loose after the machine is operated and the grease redistributes.

First, clean the undercarriage and check for leaks, then inspect the idler, rollers, sprocket, and chain for wear. Measure sag against the machine spec with the machine in normal operating condition. If parts are worn past limit, tensioning alone will not hold. VANROCK supplies track chains, idlers, rollers, sprockets, and complete undercarriage parts.
