Machine and Technical Coverage

This WA600-6R shop manual identifies the installed engine as the SAA6D170E-5, a 4-cycle, water-cooled direct-injection engine with turbocharger and aftercooler. The specification material covers the engine, power train, wheel and axle system, brakes, steering, hydraulic system, and work equipment. It also includes two lift-arm configurations shown in the specification section: 3,850 mm and 3,990 mm. The corresponding machine data includes operating weight, bucket capacity, rated load, travel speeds, drawbar pull, turning radius, overall dimensions, bucket geometry, and working dimensions.

The engine data gives the 6-cylinder 170 x 170 mm bore and stroke arrangement, 23.15 l {23,150 cc} displacement, output ratings, maximum torque, idle speeds, starting motor, alternator, and battery information. Chassis coverage includes the 3-element, 1-stage, 2-phase torque converter with lockup clutch, planetary multiple-disc transmission with 4 forward and 4 reverse stages, front and rear wheel drive, axle and final-drive construction, fully hydraulic braking, and articulated fully hydraulic power steering. Hydraulic specifications include pump deliveries for the work equipment, steering, fan, torque converter and transmission, cooling, and EPC/brake circuits, together with work-equipment and steering pressure settings and cylinder dimensions.

Fluid information is also included. The manual’s capacity table covers the engine oil pan, transmission case, hydraulic system, front and rear axles, fuel tank, and cooling system, with specified and refill capacities where given. A component weight table supports handling and removal work by listing weights for major assemblies such as the engine, radiator, torque converter, transmission, axles, differentials, hydraulic tank, pumps, cylinders, frames, lift arms, bucket, counterweight, fuel tank, cab, and other serviceable units.

Taken as a whole, the chapter structure lets a technician move from system theory and maintenance criteria to measurable standard values, then into testing, fault isolation, component removal, overhaul, installation, and final checks. The Komatsu WA600-6R Wheel Loader Shop Manual SEN02211-20 – Serial 65001 and Up is therefore useful not only when a component has already been identified for repair, but also when the cause of a performance problem still needs to be narrowed down.

Testing, Diagnostics and Workshop Procedures

The testing and adjusting material is unusually broad. Engine checks include speed measurement, exhaust gas color and temperature, valve clearance, compression pressure, blow-by pressure, engine oil pressure, intake-air boost pressure, fuel pressures, return rate and leakage, fuel-circuit bleeding, and fuel-system leakage. Power-train work includes oil-pressure testing, flushing the torque-converter and transmission hydraulic circuit, sensor adjustments, and procedures for moving the machine when the transmission valve is broken. Steering, brake, and work-equipment sections add pressure checks, performance measurements, accumulator charging and residual-pressure procedures, hydraulic circuit bleeding, control-lever adjustments, and positioner or sensor checks.

Troubleshooting is divided so that electrical faults, hydraulic/mechanical symptoms, engine symptoms, and displayed failure codes can be approached in the appropriate section. The failure-code volumes cover controller and communication faults, transmission clutch and ECMV circuits, engine sensors and fuel-system controls, monitor and switch inputs, work-equipment and steering sensors, solenoids, pressure sensors, temperature sensors, and related electrical paths. Symptom-based H-mode coverage includes weak travel, shifting shock or delay, torque-converter overheating, steering problems, brake problems, lift-arm and bucket faults, work-equipment shocks, ECSS problems, and abnormal fan operation. S-mode engine troubleshooting addresses starting difficulty, poor pickup, stalling, hunting, low output, smoke, oil consumption, fuel consumption, overheating, abnormal noise, vibration, and other engine symptoms.

Component Repair and Circuit Information

For repair work, the disassembly and assembly section gives removal, installation, disassembly, and assembly procedures with safety precautions, special-tool references, tightening values, coating materials, fluid refill instructions, and post-repair checks where specified. The coverage reaches from complete engine and radiator removal to fuel-system components, torque converter and transmission assemblies, transfer, parking brake, axles, differential and final-drive work, hydraulic pumps and control valves, steering and brake components, cylinders, cab assemblies, controllers, monitor, and air-conditioning hardware. Many procedures identify heavy component weights and lifting requirements, helping technicians plan workshop handling before the machine is opened up.

The final diagram section provides dedicated hydraulic circuit drawings for the power train, brakes, and work equipment, plus air-conditioner and machine electrical circuit diagrams. Separate electrical sets are included for steering-wheel and AJSS configurations, and a connector arrangement diagram supports circuit tracing. These drawings complement the structure/function and troubleshooting sections by showing how the components and circuits described elsewhere in the manual are connected.
