Hitachi EX200-5 Series Workshop Manual

Hydraulic excavator engineering within the Hitachi EX200-5 series utilizes a sophisticated microcomputer-based main controller logic to synchronize engine speed and pump delivery. The Isuzu A-6BG1T and Hino H07C-TD propulsion architectures provide the primary drive force, utilizing direct injection and turbocharging to maintain high torque profiles during combined operations.

Precision operation is facilitated by the KVMG-200H control valve framework, which manages 4-spool and 5-spool side sections to coordinate boom, arm, and swing movements simultaneously. This manual provides exhaustive disassembly and assembly parameters for the HPV102FW variable displacement plunger pumps and HMV-series travel motor componentry.

Integrated circuit logic governs the speed sensing control and power boost functionality, allowing for a temporary relief pressure increase to 36.3 MPa when the operator requires maximum arm roll-in force.

FAQ

Relationship between EX200-5 series workshop volumes and other Hitachi service publications? Consultation of the Foreword identifies this specific manual as one of three essential portions, specifically the Workshop Manual, while the complete service suite requires integration with the Technical Manual (Operational Principle), Technical Manual (Troubleshooting), the Operator's Manual, and the Engine Operation Manual to ensure a holistic understanding of the machine framework.

Verification of Hitachi EX270-5 logic-framework power-boost relief depth? 36.3 MPa is the magnetized relief set pressure when solenoid valve unit SG is activated for 8 seconds.

Relationship between pump delivery and engine protection logic in high-altitude parameters? Speed sensing control circuitry facilitates engine stall prevention by instructing solenoid valve unit SD to reduce main pump flow rate whenever target speed falls due to poor fuel quality or thin air at high altitudes.

Engine and drivetrain repair coverage for Hitachi EX220-5 inline architectures? 6-cylinder Hino H07C-TD propulsion units require a 110 mm bore by 118 mm stroke configuration to achieve the 117.7 kW rated output essential for standard excavation logic.

Workshop compatibility for Hitachi EX200-5 series component layout print-outs? 858 pages of high-density technical data provide structured drawings where EX200-5 data typically resides on left-hand pages while EX220-5 through EX270LC-5 data occupies the right.
