Hyster H2.00–3.00XL & S2.00–3.00XL Forklift Service Manual Set, 1980–1994 (P/N 899324)

The component repair sections work alongside the operating descriptions, troubleshooting charts, and matching system diagrams. Applicability varies by model, serial-code family, engine, and production configuration.

Early-production limits: The transmission sections direct trucks with the earlier left-side oil-filter design to separate section 1300 SRM 75, which is not included. For variant-specific A177/A187 brake work, the drive-axle chapter references separate section 1800 SRM 157, also not supplied.

PDF Search, Bookmarks, and File Contents

Search and diagram detail: Most sections have searchable text and named PDF bookmarks. MSTS and both powershift transmission PDFs have no searchable text and contain unlabeled bookmark entries. Character-encoding problems make text searches unreliable in Gauges and Steering Control Unit. Small wiring and connector labels require zooming. The final Diagrams sheet contains cable labels without complete connecting linework.

The ZIP contains 34 printable English PDFs totaling 740 pages. This total already includes nine section covers, four contents pages, six notes pages, one editorial-history page, one publication-imprint page, and the additional cable-label sheet.

Engine Overhaul, Powershift Diagnosis, and Lift-System Repair

The following highlights are a selection of the contents, not a complete table of contents. Other included topics range from cab window replacement to fork wear inspection.

• Engine repair: Step-by-step disassembly, inspection, and reassembly procedures for the Mazda M4-121G, GM 4-153/4-181, Isuzu C240, and Isuzu 4JB1.

• Powershift transmission: Torque-converter removal, pump and clutch-pack repair, differential setup, control-valve service, MONOTROL adjustments, stall testing, and pressure diagnosis.

• Hydraulics and steering: Gear-pump and main-control-valve repair, Ross HGF Hydraguide service, steering bleeding, cylinder repair, and pressure-testing procedures.

• Brakes and axles: Brake shoes, wheel cylinders, master cylinders, vacuum boosters, parking brakes, drive-axle bearings, and steering-axle service.

• Masts and carriage: Vista mast removal and repair, lift-chain adjustments, roller and shim checks, header hoses, and side-shift carriage procedures.

• Fuel and electrical diagnosis: Mazda and Rochester carburetors, Impco LPG equipment, starting and charging circuits, diesel cold-start aids, and GM MSTS/HEI troubleshooting.

• Workshop references: Maintenance schedules, torque tables, capacities, wear limits, clearances, electrical test specifications, exploded views, and hydraulic and wiring schematics.

The assumed use of lifting equipment, pressure gauges, electrical test instruments, and specialty tools makes this set best suited to trained lift-truck technicians and properly equipped repair shops.

Model and Production Differences

The serial-specific material helps match procedures and test circuits to the truck before parts or diagnostic checks are selected. It distinguishes A177 from B177 production after April 1990 and C177 production after June 1990; A187 and later B/C187 codes identify the S-series configurations.

These distinctions affect contact-point versus electronic ignition, steering-column layouts, diesel water separators, and electronic governors. The smaller H25–35XL/S25–35XL models appear in shared-system sections; their inclusion does not extend every model-specific chapter to those trucks.

Engine Overhaul and Diesel Fuel Systems

The engine chapters cover cylinder heads and valve gear, timing drives, rotating assemblies, oil pumps, blocks or liners, and coolant pumps. The frame section adds engine-and-transmission removal and installation for the H-series layouts.

For the C240, the manual separates the pre-April 1990 Diesel Kiki PE4A four-plunger pump and pneumatic governor from the VE single-plunger pump and mechanical governor used on some later trucks. Timing checks, pump removal and installation, fuel-system bleeding, and injector testing are included.

The 4JB1 has its own mechanical engine chapter. Both diesel chapters identify injection-pump repair as specialist work; their injector sections include inspection, spray-pattern testing, and opening-pressure checks requiring suitable equipment and training.

The separate C240/4JB1/4JG2 electrical chapter covers starting, charging, glow plugs, relays, timers, and cold-start diagnosis. It does not provide an internal 4JG2 engine-overhaul chapter.

Carburetors, LPG, and Ignition Faults

Gasoline and LPG coverage includes Mazda and Rochester carburetor repair, pneumatic and electronic governor checks, and the Impco CA 50/CA 100 tank, filter, vaporizer, carburetor, and governor system.

The GM MSTS chapter supplies fault charts for the ECM, HEI module, Electronic Spark Timing, MAP sensor, and coolant-temperature sensor, followed by distributor and component repair procedures.

Transmission, Brakes, and Hydraulic Configurations

The T42/T43 material applies to all A/B/C187 S-series trucks, later A177 trucks, and all B/C177 H-series trucks. It adds ring-and-pinion setup, neutral-start checks, and six pressure-test locations. The torque converter is covered for removal and installation but is non-repairable.

Brake coverage distinguishes the 260 mm and 310 mm H3.00XL assemblies and the larger brake's different drive wheels and tires. Hydraulic chapters distinguish early and later return lines, the GM-engine chain-drive lubrication circuit, and three- and four-spool control valves.

A mis-seated torque-converter hub can damage the transmission oil pump. The Mazda chapter also warns that turning the camshaft with the crankshaft gear removed and the valve gear installed can damage the valve mechanism.

Vista Masts, Schematics, and Shop Tooling

Mast material covers two-stage, free-lift, three-stage, and four-stage assemblies, including both side-shift carriage designs around the 1993 production change.

Named illustrations include the Hydraulic System Schematic, Transmission Schematic, Instrument Panel Electrical Diagram, Mazda Gasoline/LPG Wiring Schematic, Diesel Engine Wiring Schematic, and MSTS Wiring Diagram.

Special-tool callouts include Mazda valve-guide tool Hyster P/N 327686 and liner-remover components P/N 327688 and 327689. Isuzu tools include injector remover 5-8840-2034-0 and liner tools 5-8840-2039-0/5-8840-2040-0.

Raised masts, stored hydraulic pressure, LPG fuel, brake dust, and heavy drivetrain assemblies require blocking, pressure release, ventilation, lifting equipment, and shop-safety procedures.

Valve-Clearance Examples from the Engine Chapters

The Mazda M4-121G specifications list 0.30 mm inlet and exhaust valve clearance with the engine warm. The adjustment discussion also addresses the rocker-arm contact balls and rechecking an initial cold adjustment after warm-up.

The diesel chapters specify cold inlet and exhaust clearances of 0.45 mm for the Isuzu C240 and 0.40 mm for the 4JB1. Each value belongs to its engine's valve-clearance inspection and adjustment section.
