01 General

The General chapter provides the foundation for everything that follows. It includes the general assembly drawing with overall dimensions for the PC58UU-3 in both canopy and cab specifications, the work equipment range drawing with digging reach, digging depth, digging height, and dumping height figures. You also get the full machine specifications table covering operating weight, bucket capacity, engine output, travel speeds, swing speed, ground pressure, and undercarriage dimensions for road liner shoe, rubber shoe, and city pad shoe configurations. The mass list gives component weights for safe handling and transport, while the lubricants and coolant chart specifies the correct fluids and capacities for ambient temperature ranges.

10 Structure, Function and Maintenance Standard

This is the largest chapter and the technical heart of the PC58UU-3 service manual. It opens with the cooling assembly, hydraulic system layout, and swing circle, then moves through the swing machinery, track frame, idler cushion, idler, carrier roller, sprocket, and track shoe. The hydraulic pump section explains the double pump system, LS valve, PC valve, EPC valve, and servo piston operation in detail. The control valve chapter covers the CLSS system, unload valve, pressure compensation valve, logic valve, boom assist valve, center swivel joint, travel motor, swing motor, brake valve, swing brake, modulating relief valve, PPC valve, hydraulic cylinders, and the 5-spool solenoid valve assembly. The electrical system chapter covers the interference prevention system, depth measurement system, automatic boom/arm stop system, engine speed sensor, PPC oil pressure switch, controller, monitor panel, potentiometers, resistors, and sensors. Each system is presented with function, operation, structure, and maintenance standard tables showing standard sizes, clearances, and repair limits.

20 Testing and Adjusting

The Testing and Adjusting chapter gives you the standard value tables for engine, chassis, and electrical parts, then walks through every measurement and adjustment procedure. This includes measuring engine speed, engine oil pressure, compression pressure, adjusting valve clearance, testing and adjusting fuel injection timing, alternator belt tension, fuel control linkage, measuring exhaust color, testing swing circle bearing clearance, checking sprocket wear, track shoe tension, and blade control lever adjustment. The hydraulic testing section covers work equipment, swing, and travel circuit pressures, LS differential pressure, PC valve adjustment, control pump circuit pressure, solenoid valve output pressure, PPC valve output pressure, PPC valve adjustment, swing holding brake inlet pressure, travel deviation, oil leakage from work equipment cylinders, bleeding air from each part, releasing residual pressure, pressurizing the hydraulic tank, and the complete electric system resetting procedure with check of its operation. The troubleshooting section that follows is divided into E-mode (electrical system), F-mode (controller input signal system), H-mode (hydraulic and mechanical system), and M-mode (machine monitor system), with detailed flow charts and judgment tables.

30 Disassembly and Assembly

This chapter is the hands-on guide to removing and installing major components. It covers the engine and work equipment pump assembly, center swivel joint, swing motor and swing machinery, revolving frame, swing circle, rubber shoe, road liner iron shoe, swing machinery disassembly and assembly, center swivel joint disassembly and assembly, idler cushion, idler assembly, track roller, carrier roller, hydraulic cylinder assembly, and the work equipment valve. Each procedure includes lifting weights, torque values, special tools, and step-by-step instructions with the precautions that matter in the field. The special tool list at the front of the chapter gives part numbers and descriptions for the tools referenced throughout.

90 Others

The Others chapter contains the hydraulic circuit diagram, additional attachment circuit diagrams, and the electrical circuit diagrams for each serial number range. These are the schematics you need for tracing circuits, understanding flow paths, and diagnosing electrical or hydraulic faults. The diagrams are organised by serial number so you can match the correct schematic to the machine you are working on.

Why This PC58UU-3 Shop Manual Matters

Working on a compact excavator without the correct specifications is a gamble. Torque values, clearances, pressure settings, and adjustment procedures all have direct consequences for reliability, safety, and component life. The Komatsu PC58UU-3 shop manual removes that guesswork. It gives you the manufacturer’s own procedures for testing, adjusting, disassembling, and reassembling every major system on the machine.

This PC58UU-3 repair manual covers the complete machine, not just the engine or the hydraulics. You get the structure and function of each component, the maintenance standards for judging wear, the test procedures for diagnosing faults, and the step-by-step disassembly and assembly procedures for repairing them. The hydraulic circuit diagrams and electrical circuit diagrams in the Others chapter are essential for tracing faults through the system when the problem is not obvious from the component level.

For anyone maintaining a fleet of Komatsu excavators, or for an owner-operator who wants to handle their own repairs, this Komatsu PC58UU-3 PDF manual is the reference that keeps the machine running to specification. It covers both the 4D88E-3G and 4D88E-5XBB engines, and it applies to all machines from serial number 20001 and up, including road liner shoe, rubber shoe, and city pad shoe specifications.
