01 GENERAL

The opening chapter covers the safety notice, general precautions, preparations for work, precautions during work, and the foreword. It also includes hoisting instructions, coating materials, standard tightening torque tables for bolts and nuts, split flange bolts, flared nuts, electric wire code, and conversion tables. This is where you find the baseline service information and safe working practices for the Komatsu PW150ES-6K before moving into system-specific work.

10 STRUCTURE AND FUNCTION

This chapter explains how the PW150ES-6K wheeled excavator is built and how its systems operate. It covers engine related parts, radiator and oil cooler, power train for 20 km/h and 30 km/h travel speed specifications, swing circle, swing machinery and swing holding brake, undercarriage, transmission, clutch control for the 30 km/h specification, axle, suspension lock cylinder, braking train, brake and steer pump, priority valve, accumulator charge pressure, brake system accumulators, steering train, steering column, orbitrol valve, hydraulic circuit diagrams, hydraulic tank, hydraulic pump, PPC pumpless system, pilot pressure control system, control valve, CLSS, swing motor, centre swivel joint, travel motors, work equipment and swing PPC valve, travel PPC pedal, service PPC pedal, PPC pressure switch block, solenoid valves, travel-boom-stabilizer solenoid valve, boom safety valve, hydraulic cylinders for boom, arm, bucket and boom adjust, outrigger cylinder, dozer blade cylinder, work equipment, electrical wiring diagram, engine control system, electronic control system, machine monitor system, overload warning device, and breaker mode hydraulic performance. The section is heavily illustrated with cutaways, circuit diagrams, and system operation explanations.

20 TESTING AND ADJUSTING

Here you get the judgement standard values for engine and chassis, plus a standard value table for electrical parts. Procedures include checking and adjusting air conditioner compressor belt tension, adjusting the engine speed sensor, testing and adjusting governor motor lever stroke, testing swing circle bearing clearance, testing and adjusting hydraulic pressure in the work equipment, swing and travel circuits, testing and adjusting TVC valve output pressure, LS differential pressure, PPC pressure, EPC valve and solenoid valve output pressure, measuring PPC valve output pressure and testing the PPC shuttle valve, adjusting the work equipment and swing PPC valve, testing locations causing hydraulic drift, measuring oil leakage, releasing remaining pressure in the hydraulic circuit, bleeding air, and accumulator information. The troubleshooting section is extensive, with service code tables and flowcharts for communication abnormality, governor and pump controller governor control system, engine system, governor and pump controller pump control system, input signal system, hydraulic and mechanical system, and machine monitor system.

30 DISASSEMBLY AND ASSEMBLY

This chapter provides removal, installation, disassembly, and assembly procedures for major components. Covered items include governor motor assembly, hydraulic oil cooler, radiator and hydraulic oil cooler assembly, engine and main pump assembly, damper assembly, fuel tank and hydraulic tank assembly, centre swivel joint assembly, swing motor assembly, swing machinery assembly, revolving frame assembly, swing circle assembly, main pump assembly, control valve assembly, LS select valve, LS shuttle valve, pressure compensation valve, main relief valve, LS control EPC valve, EPC solenoid valve, PPC shuttle valve, work equipment and swing PPC valve, travel PPC valve, boom cylinder, arm cylinder, bucket cylinder, hydraulic cylinder assembly, work equipment assembly, bucket assembly, arm assembly, boom assembly, operator’s cab, counterweight, governor and pump controller, monitor panel, swing machinery disassembly and assembly, transmission, front axle, rear axle, bucket adaptor welding instructions, and outrigger and blade cylinders. Torque values, special tools, shim selection, and assembly precautions are given where applicable.

40 MAINTENANCE STANDARD

The maintenance standard chapter gives wear limits, clearances, and replacement criteria for engine mount, swing machinery, swing circle, control valve, suction-safety valve, swing motor, work equipment and swing PPC valve, PPC shuttle valve and travel junction valve, EPC solenoid valve, centre swivel joint, boom safety valve and arm safety valve, hydraulic cylinder, work equipment, dozer blade and outrigger cylinders, outrigger bush pins, transmission, front axle, and rear axle. It is the reference point for judging whether components are within tolerance or need repair or replacement.

What This Komatsu PW150ES-6K Shop Manual Helps You Do

With this PW150ES-6K shop manual PDF, you can diagnose hydraulic drift, set main relief and LS differential pressures, adjust the TVC valve and PPC pressures, service the swing holding brake, check the transmission clutch control circuit on 30 km/h machines, inspect axles and brakes, and rebuild components using the disassembly and assembly sequence. The structure and function chapter explains the CLSS closed centre load sensing system, the PPC pumpless system, travel motors, swing motor, control valve, and electronic control systems so you understand not just what to adjust but why. The testing and adjusting chapter gives standard values and troubleshooting flowcharts, while the maintenance standard chapter gives the limits for wear and clearance.

For a wheeled excavator of this size, correct pressures, torque values, and assembly clearances matter. The Komatsu PW150ES-6K Shop Manual UEBM000401 gives you the reference data in a single PDF, covering both 20 km/h and 30 km/h travel speed specifications. It is the same technical content used for professional service work, organised by system and chapter so you can go straight to the section you need.
