System Notes — FRAME AND BODY
The frame and body group covers the main frame, counterweight, fenders, steps, handrails, access doors, panels and the mounting hardware that ties them together. It carries every load the machine generates and every load the attachment imposes back into the structure. Cracks almost always start at a weld toe or a bolt hole where a mounting has worked loose, and a loose guard or step is both a structural and a safety issue. Parts in this group are replaced after impact damage, after crack repair, or when fasteners no longer hold torque because the hole has elongated.
System Notes — UNDERCARRIAGE
The undercarriage group covers tracks, shoes, links, bushings, rollers, idlers, sprockets, track tensioners and the recoil hardware. It carries the whole machine weight and transmits drive force to the ground, and it is normally the single largest wear cost on a tracked machine. Wear is a system: a worn sprocket accelerates chain wear, a loose track pounds the bushings, and a seized roller flat-spots the link it runs on. Parts here are replaced on measured wear — bushing diameter, shoe height, roller flange — and replacing one component out of phase with the rest usually shortens the life of both.
