Hitachi EX200-5 Series Hydraulic Excavator Workshop Manual

• Exact coverage: Hitachi EX200-5, EX200LC-5, EX220-5, EX220LC-5, EX230LC-5, EX270-5, and EX270LC-5 excavators. The non-LC EX230-5 is not listed. The package contains 1,272 PDF pages total: a 403-page Technical Manual and an 869-page Workshop Manual.
• Engine-specific repair sections separate the Isuzu A-6BG1T used in the EX200-5/EX200LC-5 from the Hino H07C-TD installations used in the EX220-, EX230LC-, and EX270-series machines, with internal overhaul, fuel-system, turbocharger, cooling, lubrication, tune-up, and electrical-equipment coverage.
• Upperstructure and hydraulic work includes cab, counterweight, main frame, pump device, regulator, pilot pump, control valve, swing device, pilot valves, shockless valve, solenoid valve unit, and pilot relief valve removal, installation, disassembly, reassembly, and maintenance standards.
• Undercarriage and front attachment procedures cover the swing bearing, travel device and motor, brake valve, center joint, track adjuster, idlers, rollers, tracks, boom/arm/bucket connections, and model-specific hydraulic-cylinder repair.
• Operational testing and fault isolation includes Dr.EX diagnostics, fault-code and symptom-based troubleshooting, engine and excavator performance tests, hydraulic pump and relief-valve testing, motor leakage checks, electrical inspection, and harness testing.
• Reference drawings and specifications include main and pilot hydraulic circuit diagrams, control-system functional diagrams, component and relay layouts, the main-pump P-Q chart, diagnostic flowcharts, and exploded or sectional views, supported by torque tables, wear limits, pressure/flow standards, adjustment data, and electrical test values.
• Build-specific distinctions include separate EX200 travel-pilot-valve procedures through serial 83346 and from serial 83347 onward, plus cab-glass dimension drawings for machines built through October 1996 and from November 1996.

Technical Coverage and Contents Breakdown

This two-file set reproduces Hitachi workshop and technical service information for the listed Dash-5 excavators. The Technical Manual explains how the machine’s control, hydraulic, electrical, pump, swing, travel, and pilot systems operate, then carries that system knowledge into performance testing and troubleshooting. The Workshop Manual provides the related repair procedures, tooling references, component standards, and removal, installation, disassembly, inspection, and reassembly information.

Hydraulic coverage goes well beyond routine hose and seal service. The manual identifies the HPV102FW main pump and its regulator and pilot-pump assemblies, along with the KVMG-200H control valve and its model-dependent internal configurations. It also covers the swing motor, swing reduction unit, parking brake, travel motors, brake valves, center joint, and the pilot-control components that command those assemblies. Control descriptions include speed-sensing pump control, power boost, arm regeneration, boom and arm anti-drift functions, travel-motor swash-angle control, and the associated Main Controller, EC, N-sensor, and pressure-sensor inputs.

The performance-test section provides factory methods for checking travel and swing speed, mistracking, parking performance, swing drift and leakage, swing-bearing play, hydraulic-cylinder cycle time, dig-function drift, control-lever force and stroke, and combined boom-raise/swing operation. Component tests cover pilot pressure, solenoid settings, main-pump delivery and flow, relief-valve operation, and swing- and travel-motor drainage. Model-group-specific standard tables help keep EX200, EX220/EX230LC, and EX270 test data from being mixed.

Engine, Electrical, and Diagnostic Repair

The EX200 engine chapters contain detailed Isuzu A-6BG1T service information, including cylinder-head and valve-train work, piston and connecting-rod service, crankshaft and cylinder-block inspection, injection equipment, oil and cooling systems, turbocharger, starter, alternator, and engine troubleshooting. The larger-model Hino H07C-TD section covers overhaul criteria, moving parts, fuel injection pump and governor, turbocharger, generator, starter, air compressor, tune-up, gasket application, and calibration procedures. These are internal engine repair sections, not merely engine removal notes.

Dr.EX coverage includes startup, stored fault codes, monitoring, service mode, and adjustable-data functions. Troubleshooting A starts with controller fault codes; Troubleshooting B starts with machine symptoms; Troubleshooting C addresses gauges, warning indicators, and the buzzer. Electrical chapters add connector handling, fuse and fusible-link checks, battery and alternator diagnosis, continuity and voltage/current testing, relay replacement, and harness-circuit checks. Factory test adapters identified in the manual include ST 7123 (P/N 4274587), ST 7125 (P/N 4274589), ST 7126 (P/N 4283594), and ST 7129 (P/N 4284347).

Repair Details, Known Traps, and Scope

The hydraulic preparation section specifically warns that trapped air in the main-pump housing can damage the pump after hydraulic components or suction lines have been opened. Floating-seal handling is treated as a component-critical operation because contaminated, scratched, or incorrectly seated sealing faces can cause rapid leakage and damage in travel and swing assemblies. The travel-pilot-valve serial break is equally important: selecting the wrong procedure or internal configuration for an EX200 built on either side of serial 83346 can lead to incorrect parts and assembly work.

Cab, counterweight, main-frame, front-attachment, and cylinder work requires rated lifting equipment, secure machine support, hydraulic-pressure release, and electrical isolation appropriate to the job. The manual also separates general fastener torque from component-specific tightening requirements and provides piping-joint, O-ring-face-seal, threaded-connection, and hose-routing guidance.

This package is the two-PDF technical/workshop set. It does not include the operator’s manual or the machine and engine parts catalogs referenced as separate publications. No separate circuit-diagram PDF is included; electrical diagnosis is handled through the system circuits, layouts, diagnostic charts, connector procedures, test specifications, and harness checks contained in the 403-page Technical Manual.
