This shop manual for the PC600-8 and PC600LC-8 is built around the way a workshop actually operates. The structure, function and maintenance standard chapter gives the internal workings of every major assembly, from the SAA6D140E-5 engine through the HPV95+95 piston pumps, control valve, swing and travel motors, and the full undercarriage. The standard value table provides the factory tolerances and judgement criteria that let a technician decide whether a component is still serviceable or must be replaced. The testing and adjusting chapter supplies the measuring methods, tool numbers, and adjustment procedures to bring those values back into specification. When something fails, the troubleshooting section works from displayed failure codes on the machine monitor, then branches into E-mode for electrical faults, H-mode for hydraulic and mechanical faults, and S-mode for engine faults, each with probable causes and standard values to confirm the repair.

What This Shop Manual Enables You to Do

With this Komatsu PC600-8 PC600LC-8 shop manual, a technician can carry out the full range of workshop operations on these 60-ton class hydraulic excavators. That includes scheduled maintenance and inspection, engine and cooling system service, PTO and hydraulic pump removal and installation, control valve and solenoid valve service, swing and travel motor repair, undercarriage rebuilds, work equipment cylinder and pin servicing, cab and electrical system work, and complete troubleshooting down to component level. The disassembly and assembly chapter lists the special tools required, the coating materials and tightening torques, and the order of operations for each major assembly, so the work can be done correctly the first time without guesswork.

Having the correct specifications matters on a machine of this size. Incorrect valve clearances, relief pressures, pump control settings, or tightening torques can lead to poor performance, premature failure, or dangerous operating conditions. The PC600-8 and PC600LC-8 shop manual gives the exact values and procedures that Komatsu specifies for these machines, along with the safety precautions that apply when working around high-pressure hydraulic circuits, hot engine components, and heavy assemblies. The troubleshooting tables and failure code references help shorten diagnostic time by pointing directly at the likely cause and the standard value that confirms it, rather than leaving the technician to guess and replace parts unnecessarily.
