01 General

This opening chapter provides specification drawings for both the HD465-7 and HD605-7, complete machine specifications, a weight table for major components, and the full fuel, coolant, and lubricant requirements. You will find machine dimensions, operating weights, dump body capacities, engine output figures, travel speeds, and gradeability data. The weight table is a practical reference for anyone planning to lift or transport major assemblies such as the engine, transmission, differential, or dump body. The fuel, coolant and lubricants section gives the specified capacities for the engine oil pan, transmission case, steering and hoist oil tank, front and rear suspension, differential case, final drive cases, fuel tank, and cooling system.

10 Structure, Function and Maintenance Standard

This is the largest chapter and covers the mechanical and hydraulic systems of both trucks in detail. It explains how each major component works, how it is constructed, and what the maintenance standards are. Topics include the radiator and cooling package, torque converter with lock-up clutch, transmission with its seven clutch packs and five planetary gear sets, axle and differential, final drive, wheels, suspension cylinders with variable damping, steering column and linkage, brake system including the brake valve, slack adjuster, accumulators, and parking brake, steering and hoist hydraulic systems, hoist valve, demand valve, EPC valve, and hydraulic pumps. It also covers the air conditioner, machine monitor system, engine control system, automatic shift control system with all-range electronic modulation, payload meter, automatic emergency steering, automatic suspension, retarder control system, sensors and switches, and VHMS controller. Hydraulic circuit diagrams, exploded views, and maintenance standard tables are included throughout. The transmission section includes the gear shifting function table showing which clutches are engaged for each speed range, and the ECMV operation tables for clutch control.

20 Testing and Adjusting

This chapter gives you the procedures and standard values for checking and adjusting the engine, chassis, and major systems. It includes engine speed measurement, engine oil pressure testing, air supply pressure (boost pressure), exhaust temperature, blow-by pressure, compression pressure, fuel pump outlet and inlet pressure, injector troubleshooting, valve clearance adjustment, alternator and air conditioner belt tension, power train oil pressure measurement for all clutches, transmission speed sensor adjustment, brake oil pressure inspection, brake air bleeding, front brake pad wear testing, rear brake disc wear testing, parking brake emergency release, front and rear suspension cylinder testing and adjustment, steering and hoist circuit hydraulic pressure testing and adjustment, dump EPC circuit pressure, air bleeding from steering cylinder, emergency dump body raising procedure, body positioner sensor adjustment, emergency escape procedures for electrical failures, machine monitor adjustment, transmission controller adjustment, payload meter initial setting, and VHMS controller setup. Detailed standard value tables list measurement conditions, units, standard values, and permissible limits for both early and later serial number ranges. This is where you will find the specifications needed to judge whether a component is within service limits or requires repair.

30 Disassembly and Assembly

This chapter provides step-by-step removal, installation, disassembly, and assembly procedures for the major components and assemblies. It covers the fuel injection pump, radiator, engine and torque converter oil cooler, engine front and rear seals, output shaft, cylinder head, engine, torque converter, transmission, differential, front and rear wheels, front brake caliper pads and calipers, front wheel hub, final drive carrier, final drive and rear brake, final drive with rear brake and parking brake, front and rear suspension cylinders (standard and buffer ring types), retarder cooling pump, steering and hoist pump, torque converter and transmission and retarder cooling and brake pump, steering valve, demand valve, hoist valve, steering cylinder, hoist cylinder, dump body, and operator seat. Each procedure includes tightening torques, special tools, gasket sealant and adhesive application points, and precautions to prevent damage during the work. The transmission disassembly and assembly section is particularly detailed, covering all seven clutch packs, the planetary gear sets, the input and output shafts, and the control valve assembly.

90 Others

This final chapter contains the hydraulic circuit diagrams for the power train, steering and hoist, and brake systems, plus the complete electrical circuit diagrams in six sections, including the transmission control and monitor system diagrams. It also includes an ABS electrical system diagram, a connectors table with pin numbers and locations, and an arrangement drawing. These diagrams are essential for tracing faults, understanding system flow, and carrying out electrical or hydraulic troubleshooting.

What This Komatsu Shop Manual Enables You to Do

With this manual, you can carry out the full range of service work on the HD465-7 and HD605-7 dump trucks. That includes routine maintenance and adjustments, diagnosing hydraulic and electrical faults, testing engine and power train performance against factory specifications, removing and reinstalling major components, and overhauling the transmission, torque converter, differential, final drive, brakes, and suspension cylinders. The testing and adjusting chapter gives you the standard values to judge wear and performance, so you can make informed decisions about repairs rather than guessing. The disassembly and assembly chapter gives you the correct procedures and tightening torques, which is critical for safety and component life on machines of this size. The structure and function chapter gives you the understanding of how each system works, which is essential for effective troubleshooting. The electrical circuit diagrams and hydraulic circuit diagrams allow you to trace circuits and understand system flow when diagnosing complex faults.

Why Technicians and Fleet Managers Use This Manual

Heavy equipment like these Komatsu rigid dump trucks depends on precise procedures and specifications. A transmission clutch pack, a brake accumulator, or a suspension cylinder that is assembled with the wrong clearance or torque can fail prematurely and create a safety risk. This manual provides the measurements, adjustment values, and step-by-step methods that the manufacturer published for these machines. Whether you are running a fleet and need to train your maintenance team, or you are an independent technician working on a customer’s truck, having the correct information at hand saves time and prevents costly mistakes. The standard value tables give you the tolerances for wear parts, the tightening torque tables ensure fasteners are correctly tightened, and the testing procedures let you verify system performance before returning the machine to service.
