Komatsu PC200LC-7 & PC220LC-7 Factory Shop Manual

• Covers 2002 Komatsu PC200LC-7L and PC220LC-7L GALEO hydraulic excavators, addressing chassis, engine, and electrical systems for serial numbers A86001 and UP.
• Official Komatsu OEM publication CEBM005802, dated March 2002.
• Features 174 distinct technical sections encompassing 638 pages of specifications, dimension drawings, maintenance standards, and wiring schematics.
• Serves as the foundational workshop reference for the A86001-series build, providing essential clearance and torque specifications for both model variants.

Component and System Coverage

Minimizing heavy equipment downtime requires precise factory data. This shop manual maps out the structural and functional specifics for the Komatsu PC200LC-7L and PC220LC-7L excavators. It details general machine dimensions and performance benchmarks before moving directly into core assemblies. Technicians will find comprehensive reference material for the engine, hydraulic pump, main control valve, swing machinery, and travel drives. Need to track down a system pressure drop? The documentation details testing, adjusting, and troubleshooting protocols alongside assembly and disassembly guidelines. It explicitly lists the strict wear limits and clearance standards required for major undercarriage and hydraulic overhauls. Working on pressurized heavy machinery carries inherent physical risks. Always verify procedures against these baseline OEM specifications and strictly follow shop safety protocols to ensure safe job site operations before pulling any parts.

Specification Highlights

Accurate tolerances make or break a hydraulic rebuild. This reference delivers extensive torque tables for critical fasteners, including structural bolts, nuts, and high-pressure hose fittings. Fluid capacity charts establish exact requirements for fuel, coolant, and gear lubricants. For powertrain diagnostics, the engine section thoroughly maps out the SAA6D102E-2 power plant. It specifies a 5.883 L displacement and a rated speed of 1,950 rpm for the PC200LC-7L. Intricate cross-sections highlight dimensional standards for internal hydraulic components. These schematics clearly define spool return spring loads alongside exact pump relief pressure settings. The main hydraulic tank capacity is documented at 200 L. Additionally, the system's relief valve is precision-set at 0.17 ± 0.07 kg/cm².
