This Komatsu PC400-6 spare parts catalog is a comprehensive illustrated guide to every component and assembly on the machine. Each section presents detailed exploded-view diagrams with corresponding part numbers, descriptions, quantities, and serial number applicability notes. The catalog covers the complete excavator from the SA6D125E-2A-7 engine through the hydraulic system, undercarriage, operator’s cab, and all attachment configurations including standard, heavy-duty, and loader arrangements. Whether you are rebuilding a hydraulic pump, replacing undercarriage components, sourcing cab interior parts, or ordering engine internals, this catalog provides the exact part numbers needed to identify and order the correct components for your serial number range.

What This Parts Catalog Enables You to Do

With this spare parts catalog, you can confidently identify and order any component for your Komatsu PC400-6 excavator. The exploded-view format makes it straightforward to trace individual parts within complex assemblies such as the main hydraulic pump, control valve, swing machinery, travel motor, and final drive. Each part number is matched to the specific serial number ranges where it applies, so you order the right variant for your machine’s build period. For workshops and parts departments, this means faster turnaround on repairs, fewer ordering errors, and the ability to quote jobs accurately without waiting on dealer support.

The catalog covers all major systems in depth: engine (SA6D125E-2A-7), fuel injection pump and governor, cooling system, air intake and aftercooler, exhaust, electrical, starting and charging, hydraulic pumps and motors, control valves, cylinders, undercarriage (track frame, rollers, idlers, sprockets, track shoes), cab and operator station, and all attachment configurations. Whether you are performing a scheduled service, a major component rebuild, or a complete machine refurbishment, the part numbers and diagrams in this catalog give you the information needed to source parts correctly the first time.

Delivered as an instant PDF download, this Komatsu PC400-6 spare parts catalog is available immediately after purchase with no shipping delays. The file can be viewed on any device — desktop, tablet, or smartphone — and individual pages can be printed for use in the workshop. Keep a digital copy on your service laptop or print the sections you need for the job at hand. With over 1300 pages covering every assembly on the machine, this is the definitive parts reference for the PC400-6 excavator, serial number 30001 and up.
