Hyster G108 E45Z, E50Z, E55Z, E60Z, E65Z Forklift Service Manual (P/N 1534734, 1534735)

• Core machine coverage: Hyster E2.00-3.20XM (E45-65Z) [G108]. Shared factory sections also list J2.00-3.20XM (J40-65Z) [A416/B416], V30ZMD [D210/E210], E1.50-2.00XM (E25-35Z, E40ZS) [E114/F114], and E3.50-5.50XL/E4.50XLS (E70-120Z, E100ZS) [D098/E098]. Mechanical coverage varies by section, so match the bracketed chassis code and installed hydraulic/controller arrangement for a non-G108 truck.
• A 1,008-page PDF set across 23 Hyster SRM sections: section dates span 2004-2008. Key AC publications are P/N 1534734 (2200 SRM 1055), P/N 1534735 (2200 SRM 1056), P/N 1534737 (2200 SRM 1058), and P/N 1534738 (8000 SRM 1059); brake coverage is P/N 897669 (1800 SRM 574).
• AC control setup and fault isolation: covers the master controller, traction and pump motor controllers, CANbus, Standard and Premium dash displays, status-code charts, performance modes, BDI/lift interrupt, regenerative braking, auto-deceleration, speed limits, steering delay, service reminders, and pump-speed parameters.
• Configuration-specific diagrams: separates manual and electro-hydraulic wiring, AC- and DC-pump arrangements, early Gen IV and later Gen V controller panels, hydraulic circuits, power-cable routing, and mast/drive-axle views.
• Factory repair coverage: documents AC and DC motor service, electro-hydraulic valve repair and calibration, hydraulic pumps and tanks, brakes, steering assemblies, drive axle/differential overhaul, frame components, mast and carriage work, and lift/tilt cylinder rebuilding.
• Specifications and final checks: supplies torque tables, hydraulic and electrical test data, contactor coil-resistance tables, battery/capacity data, mast speeds, leak checks, wear limits, adjustment data, sealants, and fastener guidance.

AC Controls, ETACC, and Electrical Diagnosis

This archive is a compiled set of individual Hyster SRM sections, each with its own P/N, rather than one 1,008-page factory publication under a single number. The controller material separates early Gen IV from later Gen V panels and shows both AC hydraulic-pump controllers and AC-traction/DC-lift-pump arrangements. That distinction matters when tracing fuses, contactors, thermal sensors, controller pins, CANbus circuits, and motor power cables. Status-code charts cover seat-switch and brake-pressure inputs, valve-coil current, motor-temperature faults, overheating, seat-brake faults, and controller communication failures.

Representative drawings include the G108 36/48-volt manual-hydraulic wiring schematic, the G108/V30ZMD 36/48-volt electro-hydraulic schematic, the G108 72/80-volt schematic, standard- and high-flow electro-hydraulic valve schematics, ring-and-pinion contact-pattern views, and mast header-hose arrangements. The included electrical diagram book, 8000 SRM 1059, covers A416, D210/E210, E114/F114, and G108. B416 and D098/E098 use separately referenced diagram publications, 8000 SRM 1225 and 8000 SRM 1203, which are not supplied here.

The ETACC chapter covers legacy PC setup, truck connection, factory-default and custom configurations, serial-number and hourmeter changes, display-language downloads, password/inspection functions, reports, logs, and live diagnostics. It identifies Hyster Interface Cable Kit P/N 1534010, ETACC installation CD P/N 1539240, and breakout kit P/N 1397311. The manuals document those items; the program, CD, cable, and password files are not included.

Electrical repair material addresses displays, switches, sensors, controllers, lighting, relays, alarms, fuses, and harness splices. The AC motor section covers disassembly, assembly, bearings, the traction-motor seal, encoder-bearing orientation, sensor checks, and troubleshooting. The DC motor chapter handles brushes, commutators, armature and field tests, and pump/steering motor maintenance. Motor controllers and the electro-hydraulic valve driver are sealed units without internal repair procedures; failed units are replaced.

Hydraulic, Brake, Drivetrain, and Mast Repair

Hydraulic coverage distinguishes early and later G108 layouts, manual versus electro-hydraulic controls, and separate steering and lift pumps. The electro-hydraulic chapter details the modular valve, EHPR and compensator cartridges, relief and check valves, tilt counterbalance valve, mini-lever module, joystick, operational tests, calibration, and troubleshooting. For manual-hydraulic trucks, the set supplies system descriptions and schematics, but the separately referenced Manual Hydraulic Control Valve 2000 SRM 562 repair section is not included.

Brake chapters cover wheel and master cylinders, service-brake disassembly and adjustment, parking-brake linkage, seat-brake variants, switch tests, and system air removal. The factory sequence matters: service brakes must be adjusted before the parking brake. A brake drum that does not fully release can drag, damage the brake, and overheat the traction motor.

Mechanical sections cover drive axle and differential setup, bearing preload, frame and counterweight removal, restraint components, steering axle and cylinder repair, steering control-unit overhaul, bleeding, and pressure checks. Mast material covers two-stage LFL, two-stage FFL, three-stage FFL, and four-stage FFL assemblies; standard, hang-on, and integral sideshift carriages; forks; lift chains; header hoses; adjustments; and cylinder leak checks. Both 4000 SRM 522 and the later 4000 SRM 1148 mast repair sections are supplied.

The AC motor instructions emphasize protecting the encoder wire and preserving encoder-bearing orientation, since encoder faults are linked to slow or jerky travel. Because this work involves high-current battery circuits, heavy components, raised mast assemblies, and pressurized hydraulics, follow the Hyster isolation, blocking, lifting, and pressure-release instructions in the applicable section.
