Hyster C160, J30XMT, J35XMT, J40XMT Forklift Service Manual (P/N 897076)

This Hyster service manual set covers J30XMT, J35XMT, and J40XMT electric lift trucks, with corresponding J1.60XMT, J1.80XMT, and J2.00XMT applications identified in the relevant sections. It combines truck-specific service information with shared Hyster component manuals. The material is suited to trained lift-truck technicians familiar with electrical testing and equipped for heavy component handling.

• DC motor repair covers traction, hydraulic pump, and steering pump motor disassembly and assembly, brush replacement, commutator inspection, and field and armature testing.
• Separate S1 and S2 transaxle procedures address removal, internal repair, bearing preload, gear backlash, and tooth-contact adjustment.
• Disc-brake service includes caliper and master-cylinder overhaul, parking-brake linkage repair, hydraulic bleeding, and operational checks.
• Steering sections document control-unit overhaul, steering-cylinder seal replacement, gear-pump repair, and wheel-hub bearing adjustment.
• Mast repair covers two-stage limited free-lift, two-stage full free-lift, and three-stage full free-lift arrangements, including carriage service, roller adjustment, lift chains, and header hoses.
• EV controller diagnostics include diagnostic hand-set operation, stored status codes, function programming, and terminal and plug wiring references for traction and pump controls.

DC Motor Maintenance and Inspection

The motor section details electrical testing criteria and assembly specifications for traction, hydraulic, and steering pump motors. Exploded assembly views support internal component identification, while the Brush Wear Replacement Guide and commutator-condition tables distinguish replacement criteria from surface problems.

Brush spring checks, commutator surfacing, and stoning procedures are covered. Motor timing is outside this section’s scope and requires specialist equipment and training.

S1/S2 Drive Units, Brakes, and Steering

The transaxle chapter identifies S1 units used through mid-1996 and S2 units used afterward. Their assemblies, components, and traction motors are not interchangeable; left and right transaxles must belong to the same series.

The Gear Tooth Contact Pattern illustration supports gear setup, and the S1 backlash procedure identifies special tool 5051462-01. A specific S2 assembly caution explains that pressing or hammering the ring gear into place can damage the gear or intermediate shaft.

Brake coverage distinguishes conventional foot-operated parking brakes from the optional electrically released arrangement. The latter section excludes the J1.60–2.00XMT models and identifies brake-release tool 2310010 and spring-compression tool 2308410.

Steering repair information also distinguishes the different pumps fitted to 36- and 48-volt trucks, whose internal components must not be mixed.

EV Controls and Electrical Diagnosis

The shared EV-100/EV-200 controller publication covers several Hyster applications. Its XMT-specific tables identify EV-100LXD dual-traction cards and EV-100LXP lift-pump cards. Separate tables for the metric-designated models distinguish Performance Standard and Energy Saver settings.

Troubleshooting charts connect status codes with operating symptoms, affected circuits, possible causes, and electrical checks. Coverage includes accelerator potentiometer inputs, seat and direction switches, contactor faults, SCR circuits, and motor temperature and brush-wear signals.

Truck electrical sections distinguish MONOTROL control from a direction lever with accelerator pedal, as well as Standard and Premium instrument panels. The Wiring Schematic with SCR Hydraulics and Arrangement, Electrical Control with Contactor Hydraulics identify the different pump-control configurations.

Control-card replacement and connector service are covered. Internal card repair and full EV controller power-component repair require separate service resources; the referenced power-component repair SRM sections are outside this set.

Mast, Cylinder, and Control-Valve Repair

Hydraulic coverage extends to lift and tilt cylinder teardown, seal replacement, leakage checks, and lowering-control valves. Mast procedures address tilt-cylinder stroke equalization, side-shift carriage repair, and auxiliary header-hose routing and tension.

The Mast and Carriage Adjustments illustration supports roller and clearance setup. The Main Control Valve Schematic explains the open-center circuit, check valves, and tilt counterbalance function.

Control-valve service includes sectional disassembly, inspection, relief-pressure checks, and optical-interrupter vane alignment. The manual specifically links incorrect control-valve adjustment to pump motor or fuse failure.

Battery, Maintenance, and Specification Data

Battery information covers sizing, minimum weight, capacity selection, specific-gravity testing, normal and equalizing charges, and charger troubleshooting. Battery repair itself requires separate specialist training and equipment.

Periodic maintenance includes fork and chain inspection, tire and wheel service, hydraulic oil and filter work, and checks for EE equipment. Frame sections address the counterweight, overhead guard, seat restraints, and hydraulic tank.

Reference data includes lift-system relief pressures, motor specifications, brush spring forces, wheel-stud torques, fluid capacities, wear limits, and metric and SAE fastener tables. Electrical testing sections provide battery-voltage criteria, potentiometer resistance ranges, and status-code thresholds.

Observe the manual’s battery-disconnection, capacitor-discharge, and mast-restraint precautions for the work being performed.
