System Notes — FUEL SYSTEM
The fuel system covers the injection pump, injectors, fuel transfer pump, filters and water separator, lines and the tank. It meters and atomises diesel at the precise moment and quantity the engine needs. Modern CAT engines run very tight injector tolerances, so the group is sensitive to water and dirt: a worn injector dribbles instead of atomising, causing rough idle, white smoke and diluted oil, while a clogged filter starves the pump under load. Parts here are replaced when the engine misfires, smokes, loses power under load, or when the water separator keeps tripping — always after the fuel quality itself has been ruled out.
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.
