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 — HYDRAULIC SYSTEM
The hydraulic system covers the main pump, control valves, cylinders, hydraulic tank, filters, hoses and all the fittings that connect them. It converts engine power into the pressure and flow that drive boom, bucket, steering and travel functions. Hydraulic parts fail mainly through contamination and heat: dirt that passes a worn breather scores pump components, aged hoses crack at the crimp, and O-rings harden and weep under pressure. A part in this group is normally replaced when a function drifts, a cylinder creeps, oil shows up under a machine that used to be dry, or the filter comes out loaded with metal.
