Technical System Architecture
This workshop manual breaks down the technical architecture of the EX300-3 and EX300LC-3 to support accurate diagnostics in the bay. It details the precise interaction between the Isuzu 6SD1-TPD engine and the HPV145D hydraulic main pump system. Chapters clearly define main relief valve parameters, flow combiner configurations, and pilot-actuated control valve operations. You will also find in-depth circuit analysis for the swing device, travel motors, and accessory cooling modules. Because heavy equipment maintenance inherently involves extreme physical forces, this text outlines crucial safety notations for high-pressure fluid handling and high-amperage welding protocols to ensure workshop safety before any repair begins.
Component Specifications and Operating Data
The technical data section provides the exact parameters required for system testing and validation. Engine performance curves thoroughly document the 161.8 kW power rating and the 833 N-m maximum torque. Standard operating modes rely on precise hydraulic settings, defining the dig pressure at exactly 29.4 MPa. Detailed electrical pinout data and fuel system parameters complete the component specifications.
- Hydraulic system capacity is documented at 310 liters.
- Engine valve clearance must be set to 0.4 mm for both intake and exhaust valves.
- Overheat switch activation temperature triggers at exactly 101 °C.
