Hyster D4D Parts Catalog – Factory Specs for the D4D Towing Winch

Look, I’ve been turning wrenches since before most of you were born. When I see a parts catalog that’s only 60 pages, I don’t dismiss it. Not if it’s from Hyster. This D4D Parts Catalog is the real deal – an original factory document for the D4D towing winch, straight out of Portland, Oregon, 1958. If you’ve ever tried to order a part for old industrial equipment using a generic aftermarket listing, you know the pain: wrong numbers, missing supersessions, and parts that don’t fit. This 60-page manual ends that guessing game.

Why? Because Hyster printed this for their own dealers. The part numbers in here are the ones the factory stocks. You get exploded diagrams, reference numbers, and the exact ordering instructions that keep your winch running. No interpretation needed.

60 Pages of Factory Parts Data

Sixty pages of nothing but part numbers, illustrations, and specification notes. Every page is a working document. Page 1 gives you the title and serial number reference – you need that serial number to order correctly, as explained on page 2. The catalog covers the entire D4D towing winch assembly, from the drum to the control cables. If you’re restoring a Hyster winch or keeping an old one in service, this is the only parts list you should trust.

Ordering Parts: The Serial Number is Everything

The manual’s ordering instructions on page 2 are blunt: Always give the serial number of machine. Then specify the name, number, and letter of the part. The illustrations might not match your exact machine if it’s been modified, so they tell you to describe the part completely if the picture doesn’t match. That’s the kind of practical advice you only get from the people who built the equipment. Aftermarket catalogs skip this step, and you end up with the wrong clutch lever or a fairlead that doesn’t bolt up.

Supplement No. 2: What Changed on Page 22?

This manual includes Supplement No. 2 dated May 15, 1958. Page 3 of the catalog lists changes: on page 22, reference 3 changed from part number 17324 to 16787. On page 35, they added a split-type bushing (94024). These updates are critical if you’re ordering parts for a later production winch. Without this supplement, you’d order the old number and wait a week for a part that doesn’t exist anymore. The original factory Parts Catalog captures these revisions; a reprint without the supplement won’t help you.

Oil Specs for the D4D Transmission

Page 2 also includes the transmission oil specification. Straight mineral oil only – no additives, no synthetic blends. Viscosity at 210°F must be 80–90 seconds Saybolt Universal. Pour point? Minus 10°F minimum. If you’re running this winch in a cold climate, you need to know that limit. The spec also calls for a viscosity index of at least 85 and a maximum of 0.05% bottom sediment and water. Black oils or residuum are explicitly not allowed. That’s the kind of detail that keeps your winch from grinding itself to death.

Factory Documentation vs. Aftermarket: The Real Difference

Aftermarket parts catalogs for the D4D are often scanned copies of copies – blurry illustrations, missing pages, illegible numbers. This Hyster OEM manual is a clean, original print from the factory files. Every part reference is legible, every footnote is present. For industrial equipment, you cannot afford to guess. A wrong bushing can seize a shaft, or a missing lockwasher can let a nut back off under load. The factory spec is your safety insurance. I’ve seen too many field repairs go sideways because someone used a “close enough” part number from a third-party book. Don’t be that mechanic.

For background on why OEM documentation matters in the Automotive Industry Overview, understand that industrial equipment follows the same principle: the source document is the only reliable reference. The Automotive Industry Overview confirms that standardized part numbering and revision control reduce downtime – exactly what this Hyster D4D catalog delivers.

Frequently Asked Questions

Does this manual include torque specs or repair procedures?

No. This is a parts catalog and instruction manual for ordering, not a service manual. It shows exploded views and part numbers only.

What is the significance of the Supplement No. 2 on page 3?

Supplement No. 2 updates the original catalog with part number changes and additions that were issued after the first printing. For example, on page 22, reference 3 changes from 17324 to 16787. On page 35, a new split-type bushing (94024) is added. If you own a D4D winch with a serial number after BWD-95644, this supplement is essential because it reflects the parts that actually fit your machine. Without it, you might order a discontinued part or miss a necessary grommet. The supplement also revises the control cable installation instructions on page 18, telling you to measure and install cables before setting the seat channels. Those details matter when you’re trying to get the winch operational without tearing it apart twice.
