Description
Komatsu HD785-7 Dump Truck Parts Book FEN02186-00-NI-02 Volume 1 – Serial N10561 and Up
This extensive parts reference is dedicated to the HD785-7 dump truck and provides the illustrated component identification needed when selecting and ordering replacement parts. The Komatsu HD785-7 Dump Truck Parts Book FEN02186-00-NI-02 Volume 1 – Serial N10561 and Up applies to machines from Serial No. N10561 onward and identifies the SAA12V140E -3B-02 engine with Engine No 505792 and up. Across 1,222 PDF pages, the book combines exploded illustrations with indexed parts listings showing part numbers, descriptions, quantities and applicable serial information.
The foreword explains the relationship between each illustration and its accompanying parts list. Individual components are assigned index numbers on the drawing, while the corresponding listing provides the ordering part number, part description and quantity used. The book also distinguishes assemblies and subassemblies and uses symbols and codes for interchangeable parts, superseded parts, kits, semi-finished parts, paint conditions and cold-weather specifications. Standard components are included alongside optional equipment and attachments, making this a particularly broad reference for the many configurations represented in Volume 1.

Illustrated Parts Identification
The Komatsu HD785-7 parts book is arranged around detailed figure-and-list pairs. Exploded diagrams identify components by index number, followed by the corresponding parts data. This organization is useful when a technician already knows the assembly being worked on but needs to distinguish closely related pieces, seals, fasteners, brackets, shafts, valves, sensors, housings or piping components before ordering.
The engine coverage is especially detailed. Individual breakdowns extend from cylinder heads, manifolds and turbochargers through the cylinder block, gear train, crankshaft-related components, lubrication, fuel injection, cooling and electrical equipment. Chassis and machine systems receive similarly extensive treatment, including transmission assemblies, rear and front axles, hydraulic tanks and piping, brake circuits, steering and hoist hydraulics, frame components, cab equipment, platforms, guards, suspension, wheels and dump body arrangements.

Taken together, these sections make Volume 1 far more than a simple engine catalog. It follows the HD785-7 through major powertrain, hydraulic, braking, steering, structural, operator-station, body and auxiliary systems while also documenting numerous configuration-specific arrangements. The repeated figure groups for cold-area equipment, extreme-hot-area equipment, dusty-terrain packages, pre-lubrication, oil and coolant quick charge, battery disconnect, ABS, ASR, auto-greasing, VHMS and ORBCOMM help identify the correct component path for differently equipped trucks.
Part Numbers, Quantities and Serial Applicability
Each illustrated group is tied to a structured parts listing. Entries can include the index code from the exploded drawing, the part number used for ordering, the component description, quantity and serial applicability. Assembly hierarchy is also shown, allowing the reader to see when a listed item belongs inside a larger assembly or subassembly. This is valuable when a repair requires identifying whether an individual piece is separately supplied or belongs to a larger component group.
The foreword also explains the book’s replacement and supply symbols. These indicate circumstances such as interchangeable parts, replacement by another listed part, discontinued parts, items supplied only as assemblies, kit components and semi-finished parts requiring additional work. Cold-weather designations are specifically described for A and B specifications, and the parts contents show numerous other machine arrangements that should be checked against the actual truck configuration before ordering.
IMAGES PREVIEW
Engine and Powertrain Depth
For the SAA12V140E -3B-02 engine, the illustrated breakdowns reach into cylinder-head components, valve-related parts, intake and exhaust manifolds, turbocharger internals, lubrication and water connections, heat shields and exhaust-brake equipment. Cylinder-block coverage expands into camshafts, followers, gear cases, flywheel components, multiple oil-pan configurations and associated sensors, gauges and suction parts. Fuel-system pages identify supply-pump, common-rail, injector, piping and filtration components, while cooling and electrical chapters cover the corresponding engine-mounted equipment.
Power transmission coverage is similarly granular. The torque converter and transmission chapter separates shafts, housings, clutch groups, carriers, valves, pumps, filters, couplings and numerous oil and brake-cooling connections. Rear-axle arrangements include differential, final-drive and brake components under different ABS, ASR and auto-greasing configurations. Front-axle pages cover the hydropneumatic suspension, hubs, brakes, cylinders, valves, sensors, lubrication and associated brake-cooling piping.
Hydraulic, Brake and Hoist Component Reference
The hydraulic chapter provides extensive component identification for the oil tank and its internal and external assemblies. It covers hoist and demand valves, filtration, suction and return circuits, transmission connections, emergency-steering piping, steering-and-hoist circuits and dump-control components. Separate arrangements reflect options such as oil quick charge, engine pre-lubrication, engine exhaust brake and ASR. Brake-oil cooling and brake piping are broken into their component groups, including valves, filters, accumulators, sensors and front and rear piping arrangements.
Cab, Frame, Body and Optional Equipment
The Komatsu HD785-7 Dump Truck Parts Book FEN02186-00-NI-02 Volume 1 – Serial N10561 and Up also extends well beyond mechanical powertrain components. Cab groups identify doors, locks, glass, wipers, air-conditioning units and piping, dashboards, monitor panels, steering components, operator seating, dump controls, electrical relays, sensors and wiring harnesses. Frame-related sections show supports, brackets, steering linkage, stairways, exhaust components and lubrication arrangements, while the platform chapters cover air cleaners, handrails, mudguards and system-specific equipment.
Body coverage includes several dump-body configurations, related parts, hoist-cylinder components, liners, platform guards, spill guards, side extensions and the tailgate assembly. Additional chapters identify wheels and tires, guards and covers, fire-protection equipment, quick-charge hardware, auto-lubrication systems, cameras, monitoring equipment, battery-isolation components and other attachments. Because the parts book expressly covers standard items as well as optional equipment and attachments, matching the illustrated arrangement to the truck’s actual equipment is an important part of correct parts identification.
Use the HD785-7 Parts Book for Accurate Component Identification
This 1,222-page Komatsu HD785-7 parts reference gives owners, parts departments and technicians a direct way to trace assemblies, identify individual components, compare configuration-specific arrangements and obtain the printed part numbers and quantities associated with the truck. The combination of exploded illustrations, structured parts lists and serial applicability is particularly useful when planning repairs, rebuilding assemblies, sourcing replacement components or checking exactly how a system is put together before parts are ordered.
Correct parts identification matters on a machine with this many variants and interconnected systems. Using the Komatsu HD785-7 Dump Truck Parts Book FEN02186-00-NI-02 Volume 1 – Serial N10561 and Up helps reduce uncertainty by keeping the illustration, index number, part description, quantity and applicable serial information together in one reference.
