Replacing wear parts as a set: track chains, rollers (top and bottom), idlers, sprockets, and the track shoes or rubber tracks. A full undercarriage is a big-ticket maintenance item, not a single failure, and is usually done all at once to avoid re-tearing the machine down.
The range above moves with these factors. The biggest swing is usually parts source and whether the failure damaged anything downstream.
