System Notes — POWER TRAIN
The power train group covers the components between the engine and the ground: torque converter, transmission, driveshaft, differential, final drives and the clutches and seals inside them. It multiplies engine torque into the pulling force the machine needs. Heat and contamination cause most failures — oil that has broken down varnishes the clutch packs, a leaking final drive seal lets grit into the planetary set, and a worn driveshaft joint shows up first as a vibration at a particular speed. Parts are replaced when shift quality degrades, when a vibration appears at one speed band, or when oil analysis shows the wrong metal.
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.
