What This Manual Gives the Technician

The PC130-8 Shop Manual is a comprehensive service document that spans the full maintenance and repair lifecycle of the machine. The specification section provides dimension drawings, working range diagrams, and a complete list of weights and lubricant capacities. The structure and function chapters explain how each major assembly works — from the variable-displacement piston pump and CLSS closed-center load sensing system to the swing machinery, travel motor, and control valve. The standard value tables give the new-machine tolerances and service limits used when inspecting components. The testing and adjusting section walks through pressure tests, speed tests, and component adjustments with the required tools and target values.

The troubleshooting chapters are particularly detailed, covering failure codes by code number, electrical system diagnostics in E-mode, hydraulic and mechanical system diagnostics in H-mode, and engine troubleshooting in S-mode. Each failure code entry lists the trouble, the controller action, the problem that appears on the machine, related information, and possible causes with standard values in the normal state. Disassembly and assembly procedures include special tool lists, tightening torques, coating materials, and step-by-step removal and installation instructions for major components. The hydraulic and electrical circuit diagrams at the end provide the system-level reference needed for tracing circuits and understanding component interaction.

Who This Manual Is For

This Komatsu PC130-8 service manual is intended for technicians, mechanics, and service personnel who need factory-level procedures and specifications for the PC130-8 hydraulic excavator. It is also useful for owners and operators who want to understand the machine’s systems, perform routine testing and adjustment, or diagnose faults using the failure code tables and troubleshooting guides. The manual assumes access to the special tools listed in the disassembly and assembly section and the testing and adjusting section for certain procedures.

Coverage Highlights

The engine section covers the Komatsu SAA4D95LE-5, a 4-cycle water-cooled in-line direct injection diesel engine with turbocharger and air-cooled aftercooler. Valve clearance adjustment, compression pressure testing, blow-by pressure testing, fuel pressure testing, and fuel return rate testing are all documented. The hydraulic system coverage includes the HPD56+56 piston pump with LS valve, PC valve, and PC-EPC valve, the CLSS closed-center load sensing system, pressure compensation valves, and the full control valve assembly with suction safety valves, main relief valve, unload valve, merge-divider valve, and travel junction valve. The electrical system coverage includes the machine monitor system, engine controller, pump controller, KOMTRAX system, and sensor specifications with connector pin numbers and signal classifications.

The disassembly and assembly chapters cover removal and installation of the fuel supply pump, fuel injectors, front and rear oil seals, cylinder head, radiator, aftercooler, oil cooler, engine and work equipment pump, fuel tank, travel motor, final drive, swing motor, swing machinery, swing circle, track roller, idler, recoil spring, track shoe, sprocket, revolving frame, counterweight, center swivel joint, hydraulic tank, control valve, PPC valves, hydraulic cylinders, work equipment, operator cab, cab glass, floor frame, air compressor, air conditioner condenser and unit, KOMTRAX modem, monitor, pump controller, and engine controller.
