Manual Contents and Structure

This factory publication breaks down the chassis and general systems for the PC300-7 and PC350-7 series excavators. It segments the machine into logical groups for efficient workshop reference. You start with a general section detailing dimensional specifications, weight tables, and exact fluid capacities. From there, the documentation dives into structure, function, and maintenance standards. This includes the engine-related components, cooling system, and the complete hydraulic assembly. Specialized chapters outline testing and adjustment baselines. You will also find extensive disassembly and assembly guidelines for major components. These cover the final drives, swing machinery, and multi-spool control valve banks. Always consult the built-in safety guidelines and pressure-relief procedures before initiating any heavy hydraulic work or teardowns.

Specification and Reference Data

Accurate torque and pressure values are critical for a reliable rebuild. This manual delivers comprehensive standard tightening torque tables covering metric bolts, flared nuts, split flange bolts, and O-ring boss piping joints. It explicitly details the Closed Center Load Sensing System (CLSS) control logic. Mechanics can reference pump discharge amount parameters and LS-EPC valve operating currents directly. You also get granular component data. This ranges from track roller diameters and recoil spring installation loads to hydraulic pump performance curves. Component pinout information and wire code classifications assist in tracking down complex electrical faults. All engine-related specifications for the SAA6D114E and hydraulic pressure settings strictly reflect the manufacturer’s original design data.
