Each section of this Komatsu PC1250-8R parts catalog pairs an exploded-view illustration with a numbered parts table listing part numbers, descriptions, quantities, and serial-number applicability. This structure makes it straightforward to trace every component from the assembly drawing to its exact part number, whether you are working on the engine, hydraulics, undercarriage, or operator’s cab. The engine coverage alone spans the complete SAA6D170E-5CR-W, from cylinder head and block through fuel injection, cooling, lubrication, and electrical systems. On the machine side, the parts book documents the hydraulic tank, main valves, pumps, swing machinery, travel system, undercarriage, work equipment, and cab in the same detailed format. For anyone maintaining or repairing a PC1250-8R or PC1250SP-8R, this parts book eliminates guesswork from part identification and ordering.
