Hyster H3.50XM, H4.00XM-5, H4.00XM-6, H4.00XMS-6, H4.50XM 2002 Parts Catalog

You’ve got a Hyster that’s down. The customer wants it running yesterday. You pull the old part, squint at the casting number, and hope the aftermarket catalog matches. That’s a gamble I don’t take anymore. This Hyster H3.50XM, H4.00XM-5, H4.00XM-6, H4.00XMS-6, H4.50XM Parts Catalog from 2002 – 514 pages of factory-sourced exploded views and part numbers – is what you put on the bench when you need the exact thing Hyster bolted on at the factory. No guessing. No returns because the counter guy misread the suffix.

Cooling System: Figures 2-1 Through 2-28

Page 1 of the manual lists the models covered. Page 5 starts the table of contents. If you’re hunting a fan drive assembly or a radiator baffle, go straight to Section 2. The Cooling section includes the fan drive assembly (Figure 2-3), exhaust manifold (Figure 2-7), water pump (Figure 2-27), and the rotary exhauster (Figure 2-28). Each figure has a parts key with Hyster part numbers. I’ve used these diagrams to find a bypass hose that no parts house had in stock – ordered the right one from the dealer using the number right off the page.

What Does the Suspension Section Cover?

Two separate entries for full suspension seats (Figures 1-3 and 1-4) and a non‑suspension seat (Figure 1-2). The Suspension section is inside Section 1 – Frame. If you’re replacing the seat on an H4.00XMS-6, the figure breakdown shows the base, armrests, and isolator mounts. Don’t buy a universal seat and drill new holes. Get the factory bracket and bolt pattern from this catalog.

13 Major Sections Organized for Speed

The manual splits into Frame, Engines, Fuel System, Electrical System, Transmission, Steering System, Brake System, Hydraulic System, Mast – two‑stage limited free‑lift, two‑stage full free‑lift, three‑stage full free‑lift, Options, and a Numerical Index. Section 2 – Engines covers cylinder block, cylinder head, camshaft, oil pump, timing gear – both diesel and LPG variants. Section 3 – Fuel System includes LPG converter, governor, throttle linkage, and the air filter. You want a part number for the control valve on a powershift transmission? Section 5, Transmission, figures 5-1 through 5-16.

Aftermarket vs. Factory: Know the Difference

Aftermarket parts catalogs re‑draw the diagrams and change the part numbers. Then your supplier sends the wrong seal kit and you lose a billable hour. This is Hyster’s own Parts Catalog, printed 03/2002, unit code K005. The diagrams match what you see under the hood. The part numbers start with the Hyster prefix – not a cross‑reference. If you’re in the Automotive Industry Overview, you know that OEM data saves warranty headaches. The related Automotive Industry Overview confirms factory documentation is the benchmark. I trust the factory print because I’ve been burned by aftermarket redraws that omitted a bushing.

Get the Right Part Number the First Time

Brake assembly figures (7-8 and 7-12) separate H3.50XM, H4.00XM-5, H4.00XMS-6 from H4.00XM-6, H4.50XM, H5.00XM, H5.50XM. The master cylinder and booster assembly is Figure 7-5. Steering axle is Figure 6-4. Hydraulic control valve is Figure 8-8. All listed with Hyster part numbers and quantities. I’ve used this manual to order a tilt cylinder for an H4.50XM – the rebuild kit number was right there in Figure 8-11. No callbacks.

Who Needs This 514-Page Catalog?

Home garage guys who maintain their own forklift or farm equipment. Shop foremen who want to stop wasting time on parts returns. This one covers H3.50XM through H4.50XM models built in 2002, including the XMS (–6) variant with the suspension seat option. If you’re working on the LPG fuel system, the converter figures (3-10, 3-11) show every diaphragm and gasket. The electrical section (4-1 through 4-18) has harness kits and distribution details. You’ll also need the HYSTER H3.50XM H5.50XM H70XM H120XM Service Manual for torque specs and procedures, and the Hyster S3.50-5.50XM Hydraulic System Service Manual for hydraulic rebuilds. For a deeper dive into the powertrain, see the Hyster H3.50XM, H5.50XM, H6.00XL, H7.00XL, S6.00XL Service Manual – 120 Pages.

Does this manual include torque specs?

No. This is a parts catalog. Torque values appear in the service manuals.

Can I order parts for a H5.00XM using this catalog?

Yes, the manual covers H3.50XM through H5.50XM models including H4.00XM-5, -6, XMS-6, H4.50XM, H5.00XM, and H5.50XM. However, note that the unit code K005 is for Europe, so some part numbers may differ for North American variants. Always cross-reference with your truck’s serial number. The manual includes 13 major sections with exploded diagrams and part numbers. For example, the brake assembly section (7-8) lists parts for H3.50XM, H4.00XM-5, H4.00XMS-6. If your truck falls outside those exact models, you may need the supplement for H4.00XM-6 etc. But the index helps you find the correct page. For a full list of referenced figures, see page 5 of the table of contents.
