Hitachi EX200-2 / EX200LC-2 (1984–1992) — Technical Manual

This manual provides essential information for the Hitachi EX200-2 and EX200LC-2 excavators.

  • Approved Component Specs: 420 cc anti-rust agent addition is mandatory for soft water engine coolant mixtures to prevent corrosion in non-antifreeze configurations.
  • Factory Service Data: 0.03–0.12 mm piston-to-cylinder clearance defines the critical tolerance for engine block integrity during a full rebuild.
  • Primary Operational Limits: 2.5V DP-sensor output voltage identifies standard load sensing operation at 12.75 bar (185 psi) differential pressure.
  • General Maintenance Procedures: 200 liter (53 US gal) total system refill capacity required for complete hydraulic oil replacement using Tellus R46 or equivalent fluid.
  • Essential Testing Metrics: 90890–03069 compression gauge ID or equivalent diagnostic logic monitors the 49 bar (711 psi) pilot oil circuit pressure.
  • Operational Parameters: 25.5 bar (370 psi) unload valve setting within the main control framework ensures minimum pump flow when levers are in neutral.
