Toyota 5FG10-30 / 5FD10-30 Forklift 1986–1989 Service Supplement Manual (P/N CE001-1)

• 827-page PDF set in three files — 734-page Toyota 5FG/5FD 10–30 Series Repair Manual No. CE001-1, an 89-page September 1991 supplement, and a 4-page standalone copy of the supplement’s emission-control wiring and connector appendix.

• Covers Toyota 5FG and 5FD models 10, 14, 15, 18, 20, 23, 25, 28, and 30, spanning 1.0- through 3.0-ton capacities. Configuration tables distinguish clutch and torque-converter models with 4P, 4Y, 5K gasoline and 2J, 1Z, or 1DZ diesel engines.

• Engine-related procedures include engine assembly removal and installation, gasoline and diesel tune-up work, air-cleaner and cooling-system service, exhaust components, starter and alternator service, plus gasoline and LPG three-way catalyst troubleshooting added by the 1991 supplement.

• Drivetrain coverage includes clutch cover repair, release and master cylinders, the 2.0- to 3.0-ton clutch booster, optional oil-clutch components, one- and two-speed torque converters, oil pumps, manual transmission service, propeller shaft repair, and differential disassembly and adjustment.

• Chassis and hydraulic sections cover front and rear axles, Koyo Seiko and Jidosha Kiki steering gearboxes, front brake inspection and assembly, brake bleeding and testing, V/FV/FSV/SV mast configurations, lift and tilt cylinders, hydraulic pump testing, and oil-control-valve overhaul and adjustment.

• Technical illustrations include one- and two-speed torque-converter hydraulic circuit diagrams, clutch- and torque-converter-model brake system diagrams, the material-handling hydraulic circuit, oil-control-valve section views, the three-way catalyst wiring schematic, and separate gasoline/LPG connector drawings.

This OEM repair manual set is best suited to experienced forklift technicians and properly equipped repair shops. Its procedures assume access to hoisting equipment, pressure gauges, precision measuring tools, and the specified Toyota special service tools rather than teaching basic mechanical practice.

Model and Configuration Identification

Coverage is divided between August 1986–August 1989 production, the revised September 1989-on configurations, and alterations introduced in September 1991. Vehicle and frame-number tables show the corresponding 10001-, 40011-, and 60011-series punching formats. They also map the standard, 02-, 40/42-, and 60/62-prefixed models to the applicable engine and clutch or torque-converter drivetrain, helping prevent the use of procedures or specifications from the wrong build.

The general section supplies component weights, lubricant types and capacities, lubrication charts, periodic maintenance data, standard fastener torque tables, and high-pressure hose fitting specifications. Separate service-data tables provide gear ratios, inspection limits, hydraulic test specifications, electrical test values, adjustment data, and assembly-specific tightening torques.

Repair and Diagnostic Depth

The main manual documents removal, disassembly, inspection, reassembly, adjustment, installation, and operational testing across the drivetrain and chassis. Major shop work includes torque-converter and transmission teardown, differential bearing and gear adjustment, axle-hub service, rear-wheel alignment, steering gearbox overhaul, brake booster and wheel-brake repair, mast removal, roller and chain adjustment, cylinder inspection, and single- or tandem-type hydraulic pump testing.

The September 1991 supplement adds the revised air cleaner, clutch pedal mechanism, 1-ton lift-cylinder and oil-pump specifications, oil-control-valve changes, and updated torque-converter measurement tests. Its gasoline emission-control troubleshooting follows the catalyst, idle switch, water-temperature switch, vacuum switch, ABCV, ECU, and oxygen-sensor circuits. The LPG section provides corresponding checks for the catalyst, injector, register, ECU, and oxygen sensor.

Specified service tools include engine unit hanger SST 09010-20111-71, mast front-pin tool 09810-20172-71, oil-control-valve spool tool 09610-10160-71, and valve-seat tool 09700-30200-71.

Important Scope and Repair Notes

The engine chapters cover installed-engine removal, installation, tune-up, and supporting systems. Full internal engine overhaul procedures are contained in separately referenced Toyota engine manuals CE604, CE602, CE603, CE601, CE617, and CE618; those publications are not included in this set. The 89-page supplement is an update to CE001-1 and is not intended to replace the main repair manual.

The manual warns that arbitrary oil-control-valve pressure adjustment can damage the hydraulic pump and other hydraulic components. It also identifies seal rings and O-rings in the torque-converter and transmission assemblies as damage-prone during installation, making the illustrated orientation and assembly ca
