Every page of this HD785-7 GALEO parts book pairs a detailed illustration with a corresponding table of part numbers. The illustrations show the exact arrangement of components so you can visually confirm what you are looking at before you order. Each parts list gives the reference number from the diagram, the Komatsu part number, a description, and the quantity required. This structure makes it possible to identify parts for the engine, transmission, hydraulics, electrical system, frame, cab, body, and every other assembly on the truck without guesswork.

What Each Section Contains

The HD785-7 parts catalog goes far beyond a simple list of numbers. The engine sections break down the cylinder head, cylinder block, air intake manifold, exhaust manifold, turbocharger, oil pump, oil filter, fuel injection pump, fuel piping, water pump, cooling fan, and every associated bracket and gasket. The transmission and torque converter sections cover the propeller shafts, torque converter internals, transmission clutch packs, control valves, lubrication valves, oil pan, and sensors in complete detail.

For the hydraulic system, the parts book documents the hydraulic tank, brake control valve, main pump, transmission piping, steering and hoist piping, brake cooling oil lines, accumulator boxes, and brake piping — all with exploded views and complete parts lists. The electrical section covers battery boxes, rear hood components, brake lines, main harnesses, rear lamps, side lamps, fog lamps, and payload meter lamps.

The main frame and related parts section includes the frame itself, rear and front supports, engine fuel filter assemblies, exhaust piping, engine control harnesses, transmission control, steering link components, and lubrication piping. The operator’s compartment section covers the cab structure, doors, glass, wiper system, dashboard, console box, operator’s seat, floor wiring, air conditioner components, and all interior fittings.

How This Parts Book Helps You

Ordering the wrong part for a haul truck costs time and money. The HD785-7 is a rigid dump truck used in demanding mining and quarry operations, and parts must be identified correctly the first time. This parts book removes the guesswork. Instead of trying to describe a component to a parts counter over the phone, you can point to the exact reference number on the diagram, read the part number from the table, and order with confidence.

The document also reveals how components are assembled — which parts are supplied as assemblies, which are available individually, and where part groups, kits, and semi-finished parts apply. The symbols and codes section at the front of the book explains interchangeability, discontinued parts, and part group markings, so you understand the notes attached to each listing. This is information you simply cannot get from a generic parts website.

Who This Komatsu HD785-7 Parts Book Is For

• Mine maintenance planners and parts managers who need accurate part numbers for HD785-7 trucks
• Heavy equipment mechanics rebuilding or repairing HD785-7 assemblies
• Parts departments at Komatsu distributors verifying part numbers and quantities
• Owners and operators of HD785-7 trucks performing their own maintenance and repairs
• Anyone sourcing replacement components for a GALEO HD785-7 from serial J20001 onward

Service Kits and Part Groups

The parts book includes dedicated service kit tables for major assemblies, including the torque converter, transmission, transmission control valve, hydraulic pump, hoist cylinder, steering cylinder, accumulator, hoist valve, demand valve, check valve, and electric lever. These kits group the seals, O-rings, gaskets, and wear components needed for a complete rebuild, so you can order everything at once rather than tracking down individual pieces.
