1997 Komatsu PC200LC-6, PC210LC-6, PC220LC-6, and PC250LC-6 Shop Manual (P/N CEBM001001)

This official 719-page OEM publication (CEBM001001) documents the 1997 Series-6 launch builds. It delivers the structural theory and baseline factory specifications essential for maintaining the hydraulic and mechanical integrity of your excavator.

• Model Coverage: 1997 Komatsu PC200LC-6, PC210LC-6, PC220LC-6, and PC250LC-6 (Serial Number A83001 and up).
• Workshop Diagnostics: Use the included troubleshooting charts and monitor panel service codes to isolate communication abnormalities directly in the bay, preventing outsourced diagnostic fees.
• Comprehensive Specs: Contains 170 technical sections, exhaustive component weight tables, and clear exploded-view diagrams of swing machinery, hydraulic pumps, and final drives.
• Covered Assemblies & Systems: Details the fuel injection pump, center swivel joint, travel motor, swing circle, recoil spring, engine throttle and pump controller, and the machine monitor system.
• Included Schematics & Visuals: Features electrical wiring diagrams, hydraulic piping drawings, electrical circuit diagrams, general assembly drawings, failure mode judgement tables, cross-sectional views, and standard tightening torque charts.

Inside, you will find exact maintenance standards and judgement criteria for inspecting disassembled components. We know that accurate part identification is critical to limiting downtime in a busy workshop. That is why the manual breaks down complex assemblies visually to support rapid diagnostics.

Instead of outsourcing complex maintenance to an expensive dealer facility, independent mechanics can follow the included step-by-step procedures to tackle advanced shop routines. This allows you to perform in-house tasks such as testing fuel injection timing, measuring engine compression and blow-by pressure, adjusting track shoe tension, and safely bleeding air from the hydraulic cylinders. By referencing this comprehensive PDF, technicians have the exact pathways needed to address electronic error codes and complete a successful repair.

The documentation takes a deep dive into the closed-center load sensing system (CLSS). You get a thorough explanation of the LS and PC valve logic, pump discharge controls, and the engine control system. Detailed hydraulic circuit diagrams map out the exact flow for the main pump, control valves, and actuators across various operating conditions.

Engine data is highly specific. The manual lists valve clearance specifications of 0.254 mm for intake and 0.508 mm for exhaust, alongside critical engine torque settings. It also confirms a 230-liter hydraulic tank capacity for this machine class, with the main relief valve set pressure anchored at 34.79 MPa (355 kg/cm²).

Please ensure you review all included hazard warnings and verify your specific machine's serial constraints prior to referencing these specifications during maintenance. This document provides a structural overview and baseline data; it is intended for reference and review by trained technicians.
