System Architecture & Documentation

This workshop manual provides the foundational structural, functional, and maintenance data required to understand these specific excavators. It breaks down the engine components, the cooling system architecture (including the radiator and aftercooler), and the complete power train. Precision is critical in the shop. Therefore, the manual details the internal design of the swing machinery and the swing circle alongside technical layouts for the final drive, track frame, and recoil spring assemblies. For hydraulic diagnostics, the text clearly maps out the control valves, PC-EPC valves, and hydraulic pumps so technicians can quickly trace system flows.

Technical Specifications & Safety Standards

Accurate shop data eliminates guesswork. This service publication lists the exact tightening torques for bolts, hose nuts, and split flange components in both Nm and kgm. Coolant system capacity is documented precisely at 18.6 liters for both models. In the weight table section, the PC160LC-7K track frame assembly weight is recorded at 3,868 kg. The data also covers the 7-spool control valve assembly, detailing main relief valve pressure settings alongside spool return spring tolerances. Having these exact factory standards allows for accurate inspection of internal components during heavy machinery repair work. High-pressure hydraulic and heavy structural systems present inherent physical hazards; always ensure a certified technician evaluates the equipment and confirms safety protocols before initiating any hands-on service or maintenance.
