Description

Komatsu HD785-7 Parts Book Serial N10561 and Up SAA12V140E -3B-02 FEN02186-00-N1-01

This extensive Komatsu HD785-7 parts book is a detailed illustrated reference for machines from Serial No. N10561 and up. Engine coverage is identified as SAA12V140E -3B-02, Engine No. 505792 and up. With exploded component illustrations paired with indexed parts lists, the Komatsu HD785-7 Parts Book Serial N10561 and Up SAA12V140E -3B-02 FEN02186-00-N1-01 is designed to help identify the exact components used throughout the truck and its major systems.

The book explains how each illustration is linked to an indexed parts list showing part number, description and quantity. It also uses symbols and codes to identify situations such as interchangeable or superseded parts, parts supplied only as assemblies, kit parts, semi-finished parts and special cold-weather arrangements. The foreword specifically notes that the book contains standard items as well as optional equipment and attachments, making this much broader than a basic engine-only parts catalog.

Illustrated Parts Identification

The Komatsu HD785-7 parts catalog is organized around figure numbers and component groups. Exploded drawings show the relationship between assemblies, subassemblies and individual components, while the corresponding lists identify the indexed items by part number and description. Quantities are also provided, including quantities for components contained within assemblies where applicable.

This format is particularly useful when working deep inside a system where the required item may be a seal, bearing, hose, bracket, sensor, valve, fastener or internal component rather than a complete assembly. The engine pages, for example, break down cylinder heads, valve components, manifolds, turbochargers, camshaft-related parts and oil-pan arrangements. Other sections extend the same illustrated approach across the transmission, axles, hydraulic circuits, cab equipment, body and optional systems.

Taken together, these sections provide a machine-wide component reference rather than concentrating on a single assembly. The catalog follows the HD785-7 from the SAA12V140E -3B-02 engine through cooling and fuel systems, transmission and axles, hydraulic and braking circuits, structural components, operator controls, wheels, dump body and a wide range of optional or special arrangements.

Standard, Optional and Special Arrangements

A major strength of this Komatsu HD785-7 Parts Book is the amount of configuration-specific material included. The contents distinguish numerous arrangements rather than assuming that every HD785-7 is equipped identically. Examples shown throughout the catalog include engine pre-lubrication systems, oil and coolant quick-charge equipment, engine exhaust brake systems, VHMS, ABS, Auto Spin Regulator (ASR), auto-greasing systems, battery disconnect switches, air-conditioning configurations, rear camera and monitoring equipment, regulatory arrangements and various fuel-quality or environmental packages.

The book also contains specific cold-area and extreme-temperature arrangements, including sections identified for -30 deg C and -40 deg C applications, along with extreme-hot-area cooling configurations. Other listings address additional filtration for bad or poor fuel, water and dust conditions, high-altitude turbocharger arrangements, sandy and dusty terrain equipment and different lighting or access configurations. This level of separation helps when identifying parts on a truck whose equipment differs from a basic standard configuration.

Engine and Powertrain Parts Coverage

The engine portion goes far beyond a simple list of major assemblies. It includes detailed illustrated breakdowns for cylinder heads, valve train components, intake and exhaust manifolds, turbochargers, camshafts, rocker-related components, gear cases, lubrication equipment, fuel-injection components, common rails, cooling components, alternators, starting motors, sensors and wiring. Individual illustrations can show assembly structure down to bearings, seals, O-rings, gaskets, retainers, brackets and fasteners.

The power-transmitting section similarly breaks down the torque converter and transmission into input and output shafts, clutch groups, carriers, housings, valves, pumps, filters, piping and mounting parts. Rear-axle coverage includes differential, final-drive and brake arrangements, while front-axle pages cover hubs, hydropneumatic suspension, cylinders, valves, lubrication, brake piping and configuration-specific ABS or auto-greasing equipment.

Hydraulic, Brake and Steering Component Reference

The hydraulic section provides illustrated component identification for the hydraulic tank and its internal parts, hoist valve, demand valve, transmission filter and piping, return and suction circuits, emergency steering lines, steering and hoist cylinders, EPC valve-related parts, brake cooling circuits and accumulators. Separate configurations are shown for combinations of systems such as ASR, ABS, oil quick charge and auto-greasing where applicable.

For a technician or parts department dealing with a specific hose, block, valve, sensor or fitting, these configuration divisions are important because visually similar systems can use different components depending on machine arrangement and serial application.

Cab, Body and Equipment Coverage

Coverage continues into the operator’s compartment with illustrated parts for the cab structure, doors and locks, glazing, wipers, air-conditioning system, accelerator and brake controls, dashboard, monitor panel, steering column, seats, dump controls, console, electrical relays and fuses, emergency-steering equipment, payload-meter components and VHMS-related hardware. Some cab groups also cover rearview-monitor and other equipment arrangements.

The chassis and body sections identify frame structures, supports, ladders, platforms, guards, mirrors, fenders, wheels, suspension parts, body assemblies and hoist components. The auxiliary and other-equipment chapters extend the reference further into tool sets, quick-charge systems, automatic lubrication, monitoring systems, fire-protection equipment and other machine options.

Part Number and Serial Application Reference

The catalog is intended to be used with the machine’s identification information. Its foreword instructs the user to specify the machine model code, machine serial number, engine serial number and service meter reading when ordering parts, together with the required part number, part name and quantity. Individual parts pages can also carry serial applicability information, allowing the illustrated breakdown and corresponding list to be checked against the machine being serviced.

For this document, the main machine coverage begins at N10561, while the engine coverage begins at 505792. Because later component changes and configuration differences can be identified within individual parts listings, matching the relevant serial information remains important when selecting a component.
