1998–2005 Hyster H2.00–H3.20XM (H177) Forklift Parts Manual (P/N 1458510)

Hyster parts publication P/N 1458510, April 2005 Customer Edition, covers 1998–2005 H2.00–H3.20XM Challenger lift trucks in the H177 Europe unit series. It identifies replacement assemblies, subassemblies, and individual parts through illustrated breakdowns and matching parts lists.

• Engine and cooling assemblies: Cylinder blocks, heads, crankshafts, pistons, valve gear, lubrication components, radiator arrangements, exhaust systems, and engine-specific mounting parts.

• Fuel and emissions systems: LPG carburetors, converters, regulators, closed-loop controls, low-emissions mixer assemblies, and diesel injection, filtration, and lift-pump components.

• Transmission and drive axle: T078, T080, and T109 Powershift breakdowns, input and counter clutches, differentials, pump drives, and Hydrostatic pump and axle assemblies.

• Hydraulics and controls: Single- and double-gear hydraulic pumps, throttle-up arrangements, control valves, tilt cylinders, and supply-and-return plumbing.

• Masts and load handling: Limited and full free-lift mast assemblies, main and free-lift cylinders, chains, carriages, forks, and integral side-shift components.

• Electrical and chassis parts: Engine and chassis harness layouts, MSTS-related components, instruments, steering, brakes, frame and floorplates, suspension seats, and cab equipment.

This catalog is suited to technicians and parts personnel who can match an installed assembly to its illustrated breakdown and serial-specific application notes.

Assembly Identification and Service Scope

The manual is divided into 13 major sections, ending with a numerical index that cross-references known part numbers to their page and item locations. Assembly keys, quantities, and footnotes distinguish similar constructions and identify parts supplied within larger assemblies or service kits.

Parts identification: Exploded views support replacement-part selection and repair planning. Step-by-step disassembly, adjustment, testing, and overhaul procedures belong to the separately listed Service Manual.

Engine, Cooling, and Fuel Variations

Engine illustrations distinguish LPG and diesel constructions, with separate GM engine-series listings and cooling arrangements for V-belts and serpentine belts. Radiator and hose tables separate engine applications instead of treating all cooling components as interchangeable.

The LPG coverage extends from carburetors and converters to closed-loop regulators and low-emissions controls. The latter include the fuel trim valve, throttle body and LPG mixer, and associated sensors. Perkins diesel illustrations identify injection equipment, the water separator, and fuel-filter and lift-pump assemblies.

Transmission and Hydraulic Parts Selection

The Input and Counter Clutch illustrations separate transmission revisions and identify friction plates, pressure plates, shafts, seals, and available kits. For the T109 clutch, the catalog specifically refers pressure-plate selection to the Service Manual; the illustrated parts list alone is not an adjustment specification.

Hydraulic Pump (Figure 8-12) separates engine applications within the double-gear Powershift arrangement. Related figures distinguish single-gear pumps and Hydrostatic systems with or without throttle-up. These application notes help match the installed pump configuration before a replacement pump or seal kit is selected.

Masts, Steering, and Brakes

Mast tables connect lift-height groups with the corresponding mast sections, chains, hoses, and cylinder parts. Main-cylinder listings distinguish left- and right-hand constructions. Integral Side-Shift Carriage (Figure 12-6) identifies the carriage frames, bearings, hooks, and associated components.

Steering Cylinder (Figure 6-4) and the brake illustrations provide separate component and seal-kit references. Brake tables distinguish Hydrostatic and Powershift applications, including parking-brake cables and linkage parts.

When replacing heavy hydraulic or mast components, verify equipment load capacities and review standard workshop safety protocols before beginning physical work.

Harness Layouts and Optional Equipment

Wire Harness (Figure 4-45) shows the MSTS-equipped LPG engine harness and its connector components. Other layouts cover versions without MSTS, neutral-start circuits, chassis wiring, cab equipment, and the powertrain protective system. These are illustrated harness and component references rather than circuit-diagnosis schematics.

Frame and option sections extend to suspension-seat components, cab doors and glazing, heaters, lighting, warning labels, and side-shift equipment.

A Preview of Fork Sizes in the Parts Tables

A few entries from the fork tables show the dimensional detail available for parts identification.

For H2.00–H2.50XM trucks, standard-taper forks are listed with 125 mm × 40 mm and 100 mm × 40 mm sections. The H3.00–H3.20XM table lists 100 mm × 45 mm and 125 mm × 45 mm standard-taper sections. These are catalog sizes for matching fork part numbers, not wear limits or inspection tolerances.

Searchable Parts Lists and Assembly Bookmarks

Search and drawing detail: Headings and parts tables support PDF text search. Embedded bookmarks open the system sections and individual assembly illustrations; the numerical index has no separate bookmark. Small annotations in harness drawings benefit from enlargement.

The download contains one printable English 844-page PDF. That total already includes two covers, 21 introductory pages, 13 section dividers, 16 blank pages, and 76 Notes pages; these pages are not additional to the stated total.
