Technical System Walkthrough

This 502-page technical document is structured to assist with diagnostics and assembly operations for the PC60-7 series. The General section provides foundational dimensional data, while the Structure and Function chapters offer a deep dive into the excavator’s hydraulic, electrical, and mechanical systems. Detailed coverage includes the Closed Center Load Sensing System (CLSS), power train layout, swing machinery, and the operation of the variable displacement piston pumps.

Additional chapters focus on Testing and Adjusting, providing the necessary metrics for performance calibration. The Disassembly and Assembly sections are formatted to help users understand component removal order and safety-critical mounting constraints. The technical data provided throughout the text is essential for maintaining machine performance within factory-defined tolerances.

Specification and Reference Data

This publication includes comprehensive torque tables for standard bolts, split flange bolts, and flared nuts, with values provided in both Nm and kgm units for accurate fastener tensioning. Fluid capacity tables cover the engine oil pan, hydraulic system, and cooling system, with specific oil type recommendations based on ambient operating temperatures. Detailed sensor reference values, pressure settings for relief valves, and electrical wire code charts are included to support electrical and hydraulic circuit analysis.

Coolant system capacity is documented at 12.5 liters in the lubrication specification table. The PC60-7 travel motor swing machinery oil capacity is set at 1.5 liters. Maximum digging force for the standard model is listed at 47 kN (4,800 kgf) in the machine performance specifications.
