Komatsu PC600-8 & PC600LC-8 Hydraulic Excavator Shop Manual SEN00128-15

Description

Komatsu PC600-8 & PC600LC-8 Hydraulic Excavator Shop Manual

The Komatsu PC600-8 & PC600LC-8 Hydraulic Excavator Shop Manual SEN00128-15 is the full multi-section service reference for these large Komatsu excavators, covering serial numbers PC600-30001 and up and PC600LC-30001 and up. It is the same shop manual body that Komatsu service technicians work from in the workshop — covering how each system is built, how it should be tested, what the correct values are, and how to take it apart and put it back together correctly. It applies to both the standard PC600-8 and the long-undercarriage PC600LC-8, in backhoe and loading shovel configurations, powered by the Komatsu SAA6D140E-5 engine.

Taken as a whole, this Komatsu PC600-8 and PC600LC-8 shop manual is a full-service reference for the machine rather than a single-system guide. It carries the factory specifications, hydraulic circuit pressures, tightening torques, wear limits, and service procedures that let a technician diagnose a fault from the failure code, verify it against a measured value, then take the offending component apart on the bench and rebuild it to the correct standard. Both backhoe and loading shovel versions are documented separately where they differ — the specification chapter, working range drawings, cylinder dimensions, weight tables, and disassembly procedures are all split out by configuration, so the manual supports the whole PC600-8 family rather than just one attachment setup.

What You Can Do With It

Because the sections cover the full system stack — engine control, hydraulic pumps and valves, travel and swing motors, undercarriage, electrical harnesses and controllers — this shop manual supports real workshop jobs rather than just minor servicing. A technician can pull the failure code table to find the right troubleshooting tree, run the pressure tests from the Testing and Adjusting section to confirm the fault, then follow the Disassembly and Assembly procedures to swap the part and torque it to specification. The Standard Value Table section gives the target values for both the engine and the chassis, so testing is not guesswork.

Typical jobs the manual supports include:

• Reading and chasing Komatsu failure codes across the engine, electrical and hydraulic systems
• Setting up and interpreting hydraulic circuit pressure tests on the main pump, control valve, swing motor and travel motor circuits
• Adjusting valve clearance, measuring compression and blow-by pressure, and testing EGR and bypass valve drive oil pressure on the SAA6D140E-5
• Pulling, stripping and rebuilding the fuel supply pump, cylinder head, and fuel injectors
• Removing and reinstalling the engine, PTO, hydraulic pumps, radiator, oil cooler, aftercooler and fuel tank
• Servicing the swing machinery, swing circle and final drive assembly with the correct special tools and torque values
• Track tension adjustment, track shoe and link work, idler, recoil spring, track roller and carrier roller rebuilds
• Rebuilding hydraulic cylinders with the correct bushing clearances and piston ring installation
• Diagnosing boom, arm, bucket, swing and travel performance problems through the H-mode troubleshooting section
• Working through the engine S-mode symptom charts for starting, power, smoke, oil consumption and overheating complaints

Why Correct Specifications Matter

Large excavators like the PC600-8 and PC600LC-8 depend on hydraulic pressures and servo adjustments that are tightly interrelated — a pump control pressure that is slightly off will show up as a slow cycle time, travel deviation, or a swing that overruns. The standard value tables and the troubleshooting flow charts in this manual are what let a technician tell the difference between a worn pump, a sticking spool, and a misadjusted valve. Getting those values right is what stops the job turning into a parts-swapping exercise and keeps the machine productive.
