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 — SERVICE EQUIPMENT AND SUPPLIES
This group covers the equipment and consumables used to service the machine rather than to run it: filter wrenches and service tools, drain and fill hardware, grease fittings and couplers, sight gauges, sampling valves, and the small hardware that makes routine maintenance possible without improvising. Items here are replaced when they no longer seal, no longer hold a setting, or when a stripped fitting turns a ten-minute service job into a two-hour one. Keeping the correct part number on hand matters more than the unit price, because a missing grease coupler usually means a missed lube point.
