Komatsu PC200-6, PC210-6, PC220-6, PC230-6 Excavator Service Manual (P/N SEBM010106)

When you're tearing down a 6-series Komatsu, guesswork isn't an option. This 1,278-page technical reference provides the hard factory data required for heavy maintenance, troubleshooting, and structural inspections on S6D102-1 and SA6D102-1 powered machinery.

• Covers 2002 Komatsu PC200-6, PC210-6, PC220-6, and PC230-6 hydraulic excavators (including LC, Hyper GX, rotary arm, and 2-piece boom configurations)
• Official Komatsu publication SEBM010106, 2002 edition
• Contains detailed technical system structures, hydraulic circuit schematics, and electrical wiring codes

Component and System Documentation

This manual breaks down the machinery exactly how it sits in the bay. You get a direct look into the engine sub-assemblies, heavy drivetrain components, and the entire hydraulic circuit network. Major chapters isolate the internal mechanics of the swing machinery, track frame recoil springs, and complex control valve banks. Need to trace a fluid issue? It maps out the main hydraulic systems with extensive pipe routing and solenoid valve diagnostic layouts specific to both standard and Hyper GX models.

Specification and Reference Data

Precision matters. That’s why the data section lists standard tightening torque values for every metric fastener, flared nut, and O-ring boss piping joint on the machine. You'll find exact fluid specifications, including the 239-liter hydraulic oil capacity and the 26.3-liter engine lubrication requirement for the 6-series block. It even benchmarks performance limits, rating the maximum digging force for the PC200-6 series at 125 kN. Conversion charts for pressure, weight, and volume are built right in to keep diagnostics moving. Working with pressurized hydraulics and heavy swing gear carries inherent risks, so technicians must review all documented factory precautions before starting any diagnostic or tear-down procedure.
