This technical manual delivers the structural and operational reference required for heavy equipment maintenance. It documents all primary systems. From the engine and hydraulics to the undercarriage and electrical control units, the guide provides the exact specifications needed on the shop floor.
Component and System Documentation
The service documentation for the 2007–present Komatsu PC200-8 series breaks the machine down into clear functional modules. This modular approach speeds up diagnostic work in the bay. It details the engine and cooling architecture, highlighting radiator and aftercooler specifications. Powertrain coverage includes travel motors, final drives, and swing machinery. Need undercarriage data? The chapters thoroughly document the track frame, recoil springs, idler assemblies, and carrier rollers. Furthermore, hydraulic system sections outline pumps, control valves, cylinders, and PPC valves. The electrical section delivers sensor data and diagnostic parameters for the KOMTRAX and monitor systems. Testing and adjusting chapters supply the technical data required to troubleshoot failure codes accurately, evaluating engine performance, hydraulic pressure, and electrical circuit continuity. Keep in mind that working on heavy hydraulic equipment involves extreme pressures and heavy loads. Always verify standard values against the machine's specific serial number and rely on proper shop safety protocols before initiating any component teardown.
Specification and Reference Values
You will find essential clearance, interference, and torque data specific to the Komatsu PC200-8 and PC220-8 excavator ranges. For instance, intake air pressure sensor resistance for the engine is clearly listed within the electrical section. Recoil spring installation load is documented at exactly 109.3 kN for the PC200-8 model. The maintenance standards specify the axial clearance limit for the swing circle bearing at 3.2 mm. Official reference values populate the standard service value tables across all major chassis, undercarriage, and engine-related components. All service data detailed within this publication serves as a structural baseline. Qualified mechanics using proper diagnostic tooling remain essential for executing actual component overhauls safely.
