Component and System Documentation

Tracking down the exact part for a 1999–2003 Kobelco SK70SR shouldn't involve guesswork. This reference manual catalogs every major system assembly to speed up component identification in the shop. You get clear visual breakdowns of the upper frame, counterweight, and cab installation. It details the precise mounting hardware and structural support assemblies required for a proper fit. Dealing with hydraulics? The documentation maps out the exact line routing for main, suction, and return circuits.

Specification and Technical Data

Beyond the frame and hydraulics, you will find comprehensive exploded views covering the engine cooling and fuel systems. This includes the radiator, air cleaner, muffler, and fuel filtration components. Because the SK70SR relies on Isuzu engine integration, having the exact part numbers for compatible filters, belts, and gaskets prevents ordering mistakes. The documentation lists standard capacities, such as the 17 L (4.5 gal) coolant system and the 50 L (13.2 US gal) fuel tank. It also notes vital hydraulic control data, including pilot valve relief pressure settings at 9860–10825 kPa (1430–1570 psi). Always verify these fluid levels and pressure settings against your machine's specific OEM documentation before operating or wrenching on the equipment to ensure safe and correct maintenance.
