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 — 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.
