Komatsu PC210, 210LC-6K & PC240LC, PC240NLC-6K Factory Shop Manual (P/N EEBM001801)

This official Komatsu shop manual (publication EEBM001801) is the primary factory reference for internal component identification, clearance data, and hydraulic circuit logic on the -6K series build. It covers the PC210-6K, PC210LC-6K, PC240LC-6K, and PC240NLC-6K excavators from serial number K32001 and up. Working on heavy machinery requires strict adherence to safety protocols to prevent severe injury. Always depressurize hydraulic circuits and verify equipment stability before applying the specifications listed in this document.

• Contains 40 pages of detailed sectional diagrams for 6-spool, 7-spool, and 8-spool control valves.
• Includes comprehensive system schematics, hydraulic pump assembly layouts, and standard bolt torque specifications across 665 pages.

Component and System Documentation

Get a clear look at the internal structure and function of the hydraulic systems. The chapters break down essential machinery components. You will find extensive coverage on engine-related parts, cooling hardware, the power train, and heavy-duty undercarriage assemblies. Need to understand the variable capacity swash plate piston pumps? The documentation maps out their exact operation. It also details the integration of the Closed Center Load Sensing System (CLSS). This gives you the necessary context for how system pressure and flow are modulated during heavy-load operations.

Specification and Technical Reference Data

Find the exact technical data for factory maintenance standards, including hydraulic relief settings and assembly clearances. The relief cracking pressure for the hydraulic tank is documented at 16.7 ± 3.9 kPa. Gear assembly data specifies a swing circle reduction ratio of 7.333. Standard final drive reduction ratios are defined at 57.000 for these specific excavator configurations. Every section is geared toward providing the precise numbers needed for professional testing and structural validation.
