1970–1985 Hyster H60E, H70E, H80E, H100E, H110E Forklift Service Manual (P/N 910102)

• Primary coverage centers on the Hyster H60E, H70E, H80E, H100E, and H110E. Shared SRM sections also reference the S30-120E, H30-60H, H40-60J/JS, J40-60A/AS, and H40-60XL for specific components, not as blanket full-truck coverage.
• Engine and fuel repair sections cover the GM 6-250 and Perkins 4.236/4.2482, with cylinder-head and valve-train work, timing components, pistons and crankshaft, diesel injection timing, injectors, Rochester carburetion, IMPCO CA 50 and CA 100 LPG equipment, HEI ignition, cooling, and ducted-fan service.
• Drivetrain material handles the three-speed manual transmission with oil clutch and the single-speed powershift with torque converter. Procedures include removal, internal inspection and reassembly, clutch-pack and planetary-gear service, control-valve repair, Monotrol and direction-control checks, stall and pressure testing, differential and drive-axle work, brakes, and the master cylinder.
• Mast chapters cover standard, full-free-lift, three-stage, four-stage, VISTA two-stage, and VISTA three-stage arrangements. They document forks and carriage removal, mast disassembly and installation, load rollers and strip bearings, chains and sheaves, sequence valves, lift- and tilt-cylinder repair, seal replacement, and final adjustments.
• Hydraulic and steering information separates early and later units, including separate auxiliary valves versus two-, three-, and four-function main valves, single- and two-stage relief arrangements, main and gear pumps, flow regulation, test ports, steering control units, axles and cylinders, pressure testing, adjustment, and air removal.
• Fault-finding support includes 13 symptom-based electrical diagnostic charts and 28 model-family electrical schematics, plus gas/LPG and diesel wiring diagrams, four hydraulic-system diagrams, early- and later-unit hydraulic schematics, and troubleshooting tables throughout the set.
• The package contains 574 pages across 37 factory service-section PDF files. It provides torque tables, hydraulic and transmission test specifications, capacities and approved fluids, inspection limits, clearances, maintenance schedules, travel and lift data, tire information, fastener grades, and identified service tools.

Component and System Documentation

The chassis pages distinguish H60-80E and H100-110E frame and counterweight arrangements, including the H80E Stevedoring configuration. Powertrain coverage branches between manual/oil-clutch and powershift trucks, with separate standard- and high-speed axle data. Hydraulic chapters distinguish early and later circuits. Several component sections apply to more than one Hyster family, so their model and serial-code notes matter before parts or repair procedures are selected.

By topic, the set contains 172 pages for mast, hydraulic, and steering systems; 144 for engines, fuel, ignition, and cooling; 114 for transmissions, axles, and brakes; 101 for electrical diagnostics, wiring, instruments, charging, and starting; and 43 for the frame, periodic maintenance, capacities, and fastener data.

The Perkins chapter explains the differences between the 4.236 and 4.2482, provides engine serial coding, and covers fuel-system air removal, injection-pump timing, valve-clearance adjustment, injectors, throttle linkage, and cold-start equipment. Internal injection-pump repair is directed to an authorized specialist because dedicated test equipment is required. The GM material includes the 6-250 and related 4-153, 4-181, and 3.0L designs, with cylinder-head, camshaft, timing-gear, piston, crankshaft, lubrication, specification, and troubleshooting sections. The ducted-fan chapter identifies special driver kit P/N 321006 and driver P/N 321008 for bearing and seal work.

Powershift repair goes beyond operational theory, covering clutch discs and plates, the planetary carrier, control valve, stator-support and turbine-shaft checks, converter alignment, Monotrol adjustment, stall testing, circuit checks, and pressure ports. The manual-transmission chapter adds synchronizers, shaft and gear service, pinion-carrier and differential setup, bearing adjustment, backlash, and tooth-contact checks. Document identifiers include 1300 SRM 111 for powershift repair, 1300 SRM 113 for powershift description and operation, 4000 SRM 197 for VISTA mast description and operation, 4000 SRM 198 for VISTA mast repair, and P/N 910102 / 2100 SRM 103 for Tilt Cylinders.

Technical Data Preview

Named illustrations include Electrical Wiring Diagram (Gas and LPG), Electrical Wiring Diagram (Diesel), Hydraulic Schematic-Early Units, Hydraulic Schematic-Later Units, Full Free-Lift Mast Sequence, and H60-110E Powershift Port Locations. The electrical file opens with charts for total power loss, no-crank and slow-crank conditions, charging faults, gauge and horn problems, and powershift engagement before its model-family schematics.

The set also flags repair traps that are easy to miss. Gear-pump housings and seals must remain indexed to the correct direction of rotation and oil passages; assembling them in the wrong position can cause pump failure or accelerated wear. In the three-speed transmission, using the range main shaft to force out the input bearing carrier can damage the high-gear synchronizer ring.

Forklift mast, counterweight, drivetrain, brake, and hydraulic repairs involve suspended loads, stored pressure, and major center-of-gravity changes. Follow the manual's blocking, mast-restraint, lifting, electrical-isolation, and pressure-release precautions, and have major repair work performed or checked by a qualified lift-truck technician.
