Chapters Covered

The workshop manual is organised into four major sections, each covering a distinct area of the machine:

• Section 1 — General: Precautions for Disassembling and Assembling, Tightening Torque Specifications, Torque Chart, Piping Joints, Periodic Replacement of Parts
• Section 2 — Body: Cab (Removal and Installation, Air Conditioner), Engine/Alternator (Removal and Installation, Disassembly, Inspection, Assembly), Pump Device (Main Pump, Regulator, Gear Pump, Drive Shaft), Drive Device (Wheel Motor, Parking Brake, Wheel Reduction Device), Front Axle (Spindle Assembly, Trailing Arm, Front Wheel Adjustment), Tire/Rim/Air Pressure, Front Brake (Brake Head, Lining, Air Bleeding), Brake Valve (Disassembly, Inspection, Assembly, Cartridge Seal), Brake Accumulator (Rear and Front, Charging Nitrogen Gas), Steering System (Steering Column, Driveshaft, Steering Valve, Flow Amplifier, Steering Cylinder, Main Accumulator), Frame Suspension (Front and Rear Suspension Cylinders)
• Section 3 — Hoist Device: Hoist Control Valve (Removal and Installation, Disassembly, Assembly, Overload Relief Valve, Make-Up Valve), 4-Unit Proportional Control Solenoid Valve, Hoist Cylinder (Disassembly, Inspection, Assembly), Dump Body (Removal and Installation)
• Section 4 — AC Drive Control Device: Control Cabinet (REC Unit, INV Unit, MFR Unit, FAN Unit, DSC, DC/DC Converters, CS Unit, AFR Unit, Auxiliary Inverters, Relays, Coolant Level Sensor, Heaters, CT301, PUMP301, Coolant Change Procedures), Grid Box (Removal and Installation), Alternator Cooling Blower, Wheel Motor Cooling Blower

What sets this 4000ACI workshop manual apart is the depth of its component-level coverage. The drive device section walks through complete disassembly and assembly of the wheel motor, parking brake, and wheel reduction device, including first and second stage carrier assemblies, brake assembly, wheel bearing preload procedures, brake clearance adjustment, friction disc wear measurement, and break-in operation. The steering system section covers the steering valve, flow amplifier, steering cylinder, and main accumulator with disassembly, inspection, assembly, and test procedures. The AC drive control device section is equally comprehensive, covering the control cabinet and all its internal units down to individual board and component replacement.

The manual also includes a dedicated section on periodic replacement of parts, listing the components that must be replaced at set intervals regardless of apparent condition — including fuel hoses, brake hoses, steering hoses, pump suction and delivery hoses, hoist line hoses, and seat belts. Maintenance standards and allowable limits are provided throughout so you can judge whether a component can be reused or must be replaced.

What This Manual Enables You to Do

With the Hitachi 4000ACI Rigid Dump Truck Workshop Manual W8R7-E-01 on hand, a qualified technician can perform:

• Complete engine and alternator removal, disassembly, inspection, and assembly
• Main pump, regulator, gear pump, and drive shaft service
• Wheel motor, parking brake, and wheel reduction device overhaul
• Front axle spindle, trailing arm, and wheel bearing service
• Front brake, brake valve, and brake accumulator repair and adjustment
• Steering column, driveshaft, steering valve, flow amplifier, and steering cylinder service
• Front and rear suspension cylinder disassembly, assembly, and charging procedures
• Hoist control valve, proportional control solenoid valve, and hoist cylinder service
• Dump body removal and installation, including hinge pin and body pad service
• AC drive control cabinet, grid box, cooling blower, and all internal component replacement
• Periodic replacement of critical parts including hoses, seals, and seat belts

Each procedure includes the tightening torques, clearances, wear limits, and adjustment values needed to meet Hitachi service standards. The manual also includes safety alerts, handling precautions for O-rings, backup rings, and floating seals, and procedures for bleeding air from hydraulic circuits.

Why This Manual Matters

Heavy haul trucks like the Hitachi 4000ACI operate under extreme loads in demanding environments. Incorrect assembly, wrong torque values, or missed wear limits can lead to premature component failure, unplanned downtime, and costly damage. This workshop manual gives you the exact procedures and specifications Hitachi engineers use when servicing these machines. From the correct tightening sequence for cab mounting bolts to the preload adjustment procedure for wheel bearings, every critical step is documented. The manual also includes maintenance standards and allowable limits so you can determine whether a component can be reused or must be replaced.
