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.
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.
