Complete Manual Information
Komatsu PC150-6K / PC150LC-6K Shop Manual - 2001 Edition
This professional Shop Manual serves as the primary technical authority for the maintenance, troubleshooting, and repair of the PC150-6K series excavators. It integrates a critical engineering mandate regarding hydraulic system longevity: during the installation of high-pressure hoses, technicians must ensure no torsional stress (twisting) is present, as the standard 34.8 MPa operating pressure will cause immediate wall failure in compromised lines. Adhering to these factory-specified routing and torque protocols is the fundamental requirement for maximizing machine uptime and ensuring the operational safety of the high-pressure circuits.
Technical Applicability & Serial Ranges
The engineering specifications and service protocols in this document are strictly applicable to the following chassis configurations and production sequences:
Standard Undercarriage (PC150-6K)
- Serial Number Range: K32001 and up
- Serial Number Range: K34001 and up
Long Undercarriage (PC150LC-6K)
- Serial Number Range: K32001 and up
- Serial Number Range: K34001 and up
Operational Asset Protection & ROI
- System Calibration Precision: Access factory-set relief pressures for the HydrauMind (CLSS) system, adjustable from 31.87 MPa to 34.81 MPa to maintain the rated 80 kW flywheel output.
- Structural Integrity: Implement exact torque sequences for the revolving frame and swing circle mounting bolts to preserve the factory-rated 7.833 reduction ratio.
- Lifecycle Extension: Utilize specific ambient temperature viscosity charts for SAE 10W to 15W-40 lubricants to ensure engine protection across all climatic operating zones.

Technical Depth & Factory Benchmarks
Service operations must calibrate the primary hydraulic assembly to the following engineering benchmarks to ensure full machine breakout force:
- Main Relief Pressure: 31.87 MPa (Standard) to 34.81 MPa (Power Max).
- LS Differential Pressure: 1.34 MPa to 2.62 MPa for precise actuator control.
- Swing Performance: Rated at 12.0 rpm with a maximum slope angle capability of 20 degrees.
- Travel Speeds: Three-stage regulation (Low: 2.4 km/h, Mid: 3.9 km/h, High: 4.9 km/h).
Visual Navigation Aids
The manual utilizes standardized technical symbology for the rapid identification of critical service tasks:
- Lifting Indicators: Components exceeding 25 kg are marked with a weight symbol to mandate the use of certified hoisting equipment.
- Hydraulic Schematics: Detailed mapping of the 6-spool + 1-spool control valve and CLSS (Closed-center Load Sensing System) circuit logic.
- Tightening Graphics: Visual references for flared nut sealing surfaces and split-flange bolt patterns to prevent leakage.
Table of Contents
- 01 GENERAL: Specification drawings, weight tables, and fluid capacities.
- 10 STRUCTURE AND FUNCTION: Power train, final drive, swing machinery, and hydraulic logic.
- 20 TESTING AND ADJUSTING: Troubleshooting flowcharts, pressure measurement, and monitor codes.
- 30 DISASSEMBLY AND ASSEMBLY: Step-by-step removal and installation protocols for major assemblies.
- 40 MAINTENANCE STANDARD: Wear tolerances and judgment standards for disassembled parts.
Operational Limits & Specifications
Strict adherence to these fluid types and torque values is mandatory for operational compliance:
- Engine Oil Pan: 16.0 Liters (API CD Classification).
- Hydraulic System: 196 Liters total capacity (Refill: 135 Liters).
- Swing Machinery Case: 8.0 Liters (G2-LI Grease).
- Standard Torque (M12 Bolt): 112 ± 9.8 Nm (11.5 ± 1.0 kgm) for structural fasteners.
