White MY40B, MY50B, MY60B, MY70B, MY80B Parts Catalog

Ordering the wrong part for a forklift costs you time and money. I’ve seen guys pull a transmission only to find the replacement doesn’t match because they guessed the serial number range. This White MY40B, MY50B, MY60B, MY70B, MY80B Parts Catalog takes the guesswork out. It’s a factory-issued 116-page document covering gas, LP-gas, and diesel variants for the MY40B through MY80B series from White Materials Handling. If you’re rebuilding a mast, replacing a torque converter, or sourcing hydraulics, you need the OEM part numbers straight from the source – not some aftermarket cross-reference that might be off by a digit.

Serial Number Identification for White MY40B through MY80B

Every serial number prefix is listed on page 1. For example, the MY40B starts at 48400001 for gas and LP-gas models, MY50B at 48500001, through MY80B at 50200001. The diesel versions add a ‘D’ suffix and have separate ranges. There’s also a second set of serial prefixes (like MY40-50B 6400101) that cover later production changes. Without this data, you’re flying blind. A dealer will ask for your serial number – this catalog shows you exactly which parts correspond to which build.

How to Use the Supplement Pages

This catalog includes a supplement (page A-2 onward) that revises and updates part numbers. For instance, the original bolt 50A1440 was superseded to 907651. The supplement also adds a new transmission case for diesels with lower inching packs, new relief valve cover, and gasket part numbers. If you skip the supplement, you’ll order parts that may have been redesigned. I’ve seen guys bolt on an old part number and have to redo the job. Don’t be that guy.

Parts Breakdown: Gas, LP-Gas, and Diesel Variants

The catalog covers all three fuel types – gasoline, LP-gas, and diesel. The diesel models (MY40BD through MY80BD) have different engines, fuel systems, and torque converters. The supplement specifically notes changes for diesels with ‘latest lower inching’ and adds parts like a priority valve spring and a new converter assembly used after certain serial breaks. The main catalog contains exploded views and part numbers for axles, transmissions, mast assemblies, and hydraulics. Need the charge pressure? That’s in the service manual – this parts catalog gives you the numbers to order what the schematic calls out.

Why an OEM Parts Catalog Beats Aftermarket

Aftermarket parts catalogs often combine model years or omit supersessions. This White original print gives you the exact engineering part numbers. The supplement page A-10 lists a new converter used on MY40-50B SN.6400432 and after, Gas & LP, and MY40-50BD SN.6450167 and after. A generic catalog won’t tell you that. You’ll end up with a converter that doesn’t have the right mounting or pilot diameter. Factory documentation costs less than one wrong order.

FAQ

Does this parts catalog include torque specs or repair procedures?

No. This is a parts catalog – it lists part numbers, serial number breaks, and exploded diagrams. For torque specs and repair steps, you need the factory service manual for the engine and drivetrain.

How do I know if my forklift’s serial number falls within the covered range?

The catalog opens with serial number ranges for every model. MY40B starts 48400001, MY50B 48500001, MY60B 48600001, MY70B 48700001, MY80B 50200001. Diesel variants have separate prefixes (48800001, etc.). If your serial number starts with those digits, this catalog covers it. If you’re outside those ranges (e.g., a later production update), the supplement tables at the back list newer part numbers that may apply – check the note on page A-10 for converter changes after certain serial numbers. I’d still recommend verifying with the dealer if your machine is outside the original run, but this catalog gets you 95% of the way there. The supplement also cross-references supersessions like bolt 50A1440 changed to 907651, so you can order the current part.

Don’t waste a day hunting down part numbers. Access the Factory Manual and get the exact OEM listings for your White forklift. Keep it on your shop tablet or print the pages you need – the 116 pages cover gas, LP-gas, and diesel variants of the MY40B, MY50B, MY60B, MY70B, and MY80B. When you’re ordering from a dealer, you’ll have the part number in hand and you can verify the serial number ranges yourself. That’s the difference between a job done and a job that sits waiting for the wrong part to be returned.
