White MY20, MY25, MY30, MY40C 1980 Parts Catalog – OEM Forklift Part Numbers

You ever pull a part off a forklift, get to re-assembly, and find the replacement you ordered doesn’t fit because the aftermarket catalog had the wrong cross-reference? I’ve seen it waste a full day’s labor. This is the White MY20, MY25, MY30, MY40C 1980 Parts Catalog – the factory-issued document that gives you the exact part numbers White used when these trucks were built. No guesswork, no aftermarket abbreviations. 81 pages of exploded views and numerical indexes.

Transmission and Brake Parts: Sections A-14 to A-22

Transmission work on a forklift means dealing with clutches, shafts, control valves, and the converter. The catalog breaks it down: Transmission Clutches, Shafts (A-14), Control Valve, Transmission (A-15,A-16), and Converter (A-13). Brake system parts – master cylinder, wheel cylinders, parking brake linkage – are all in A-19 through A-22. You need the seal kit for the control valve? The page A-15 shows the kit part number 20-7301206 (for 1½” or 1¼” valve). That came straight from page 2 of the OCR. No translation errors.

Engine Group: From Camshaft to Cylinder Head

The Engine section (F-2 to F-12) covers everything from the Camshaft (F-10), pistons and connecting rods (F-8), Cylinder head (F-9), to the oil pan (F-11) and oil filter (F-12). If you’re rebuilding the top end, get the gasket set from page 2: part 35A5533 (engine overhaul kit) or the valve grinding gasket set. These are the numbers the dealer used. Don’t trust a third-party list.

81 Pages of Organized Part Data

This catalog is from 1980 and covers serial number ranges specified on page 1: MY20 from 49900001, MY25 from 50000001, MY30 from 50100001, and MY40C from 6200501. It also includes the MY20-30 with 6200101 and after. 81 pages total. The Table of Contents starts on page 3 and lists every assembly group with letter-number codes: A for drivetrain, B for steering, C for chassis/electrical, D for hydraulics, E for fuel/air, F for engine, G for decals. You find the group, flip to the page, and the part number is right there.

Use the Numerical Index to Cross-Reference Part Numbers

Some aftermarket catalogs give you one number and claim it fits every model. This White catalog includes a Numerical Index (A-4) that links each part number back to the assembly page. Need the element for the air cleaner (Cyclopac)? It’s 35P1873. Spark plug? Champion plug 20-7000695. The index lets you verify that number appears in the right group before you order. That alone keeps you from buying the wrong filter element.

Camshaft, Pistons, and Valves: Engine F-Section Details

Under the F section, you get the complete engine breakdown. Camshaft (F-10), tappets (F-10), valves (F-9), connecting rods (F-8), crankcase (F-6), crankshaft (F-8), flywheel (F-7), and cylinder head gasket sets. If you’re rebuilding the engine of a White MY30, you need to know the exact valve grind set part number. The catalog lists it on page 2 as “t=gaskets, valve grinding” – but the actual number is in the numerical index. You can’t fake that level of detail with a generic manual.

Who Should Use This Catalog?

If you’re maintaining a White MY20, MY25, MY30, or MY40C forklift at a warehouse, construction yard, or dealership, this is your parts bible. DIY mechanics who do their own engine or transmission overhauls will save themselves the headache of mismatched parts. Professional techs need it to quote jobs accurately – no more calling the parts house with “it looks like this” descriptions. Shop owners can hand it to a junior tech and say “find the part number for the lift cylinder seal kit” – the answer is in section D-2.

Does this catalog include torque specifications?

No. It’s a parts catalog, not a service manual. You still need the factory service manual for torque values and procedures.

What models are covered?

White MY20, MY25, MY30, and MY40C gasoline/LP-gas fork lift trucks from 1980 with serial numbers listed on page 1. Includes MY20-30 up to a certain range. Check your truck’s serial plate.

Is the part numbering system the same as later White forklifts?

Not necessarily. White Motor Corporation was sold and later became part of other companies. The 1980 numbering scheme (e.g., 35A5533 for engine gasket kit) is specific to that era. If you have a 1990s White forklift, this catalog will not cross-reference. You need a later parts manual for those trucks. However, some common parts like spark plugs (Champion 20-7000695) may still be interchangeable – but always verify with your truck’s VIN.

Can I use this to order aftermarket parts?

Yes. You take the OEM White part number from the catalog and give it to the aftermarket supplier. They cross it to their brand. But be careful – cheap aftermarket parts often use different materials. The catalog gives you the factory spec, but you still choose the quality level. For critical components like brake master cylinders or lift cylinders, I’d stick with OEM White parts if still available.
