This parts book is structured for efficient component identification. Each assembly group includes a clear exploded-view diagram with numbered callouts, followed by a detailed parts table listing the item number, part number, part name, quantity required, and serial number applicability. This layout allows a technician or parts counter professional to quickly locate the exact part needed for a specific machine serial number, confirm the quantity required for a complete repair, and cross-reference superseded or alternative part numbers where applicable.

Why This Parts Book Matters

Ordering the wrong part for a Komatsu HD785-7 is expensive and time-consuming. A 830-page illustrated parts catalog eliminates guesswork by providing the exact part numbers for every component on the machine, from the smallest O-ring to complete assembly groups. Whether you are maintaining a fleet of haul trucks, performing a scheduled rebuild, or repairing a sudden failure, having the correct parts information at your fingertips keeps the machine productive and avoids costly downtime waiting for the wrong part to be returned and replaced.

This Komatsu HD785-7 Dump Truck Parts Book covers the SAA12V140E-3B-02 engine and the complete HD785-7 chassis for machines with engine serial number 500001-UP and chassis serial number 7001-UP. The exploded diagrams and part tables provide a complete visual reference for disassembly, assembly, and component identification across all major systems: engine, fuel, cooling, electrical, transmission, torque converter, axles, brakes, suspension, hydraulic, steering, hoist, operator’s cab, body, and chassis.
