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 — IMPLEMENTS
The implements group covers the working attachment and its linkage: bucket or blade, cutting edges, teeth and adapters, pins and bushings, linkage arms, tilt cylinders and the wear plates that protect them. This is the group that actually does the work, so it wears fastest. Cutting edges round off, teeth break at the adapter, and pins and bushings develop play that spreads shock loads back into the linkage. Parts here are replaced on measured wear — pin and bushing clearance, edge thickness, tooth height — rather than on hours, because a worn edge costs fuel and cycle time long before it fails outright.
