Across these four sections, this Workshop Manual walks a technician through every major structural and hydraulic assembly on the EH4000AC II, from the cab mounts and front axle down to the hoist control valve and AC drive cooling blowers, with the shop-floor detail needed to pull a component off the truck and put it back correctly.

Torque and Maintenance Data

The General section alone is worth the download: it lists specific tightening torques (in N·m, kgf·m and lbf·ft) for critical fasteners such as the cab mounting bolts, engine mounting bolts, hoist cylinder pin bolts, travel device mounting bolts and rear axle hinge pin bolts, plus a full general torque chart by bolt diameter, bolt-tightening order diagrams, split-flange sealing procedures and a periodic replacement schedule for fuel, brake, steering and hoist hoses.

Hoist and Driveline Procedures

The Hoist Device section documents removal, disassembly and assembly of the hoist control valve, the 4-unit proportional control solenoid valve, the hoist cylinder and the dump body itself, each with weight callouts and exploded parts breakdowns. The Body section works through the driveline, front axle, tire/rim/air-pressure procedures, front brake and brake valve/accumulator service, and the frame suspension cylinder, while the AC Drive Control Device section covers the control cabinet, grid box and the alternator and wheel-motor cooling blowers unique to this AC-drive rigid dump truck.

Whether you’re pulling the hoist control valve for a rebuild, retorquing cab or engine mounts to factory spec, or servicing the alternator cooling blower on this Hitachi EH4000AC II, this Workshop Manual gives you the exact procedures, torque values and part callouts Hitachi wrote for the job. Correct torque and assembly sequence directly affect the safety and service life of a machine this size, so working from the actual EH4000AC II Workshop Manual instead of guesswork protects both the machine and the technician. It downloads instantly as a PDF after checkout, works on any phone, tablet, laptop or shop PC, needs no shipping or waiting, and can be printed page-by-page for the shop floor whenever you need this Hitachi EH4000AC II Workshop Manual on hand.
