This PC1250-8R parts book gives you the complete component structure of the machine. Every assembly is broken down into its individual parts with reference numbers that correspond to the illustrated exploded views, so you can trace exactly which component sits where and how the assemblies fit together. The coverage spans the full machine – from the engine through the cooling, fuel, electrical, air, and hydraulic systems, into the revolving frame, operator’s cab, undercarriage, and work equipment. Each part listing includes the Komatsu part number, description, quantity required, and serial number applicability, making it straightforward to confirm a part is correct for a specific machine before ordering. The exploded diagrams are the core of the catalog, giving a visual reference that parts lists alone cannot provide.
