System and Component Documentation

This factory manual details the core operational structures of the Komatsu SK714-5, SK815-5, and SK815-5 turbo loaders. The documentation outlines the mechanical layout of the power train, including the transmission chains, axles, and hydrostatic final drives. Hydraulic systems, including the piston pumps, control valves, and the CLSS (Closed center Load Sensing System), are fully illustrated. Electrical system chapters provide comprehensive schematics for engine line circuits, including connector pinouts, fuse ratings, and component locations.

Technical Specifications and Calibration Values

The technical sections provide baseline data for system performance and maintenance. Control valve operating pressures are documented at 181–191 bar, while pilot system travel pressure is listed at 12.7 bar. Hydraulic performance is further defined by a standard travel motor pressure of 309 kPa and servo-control pressures of 25–28 bar. Engine cooling capacity is 9 liters for standard thermal management.
