Part Number Geek Question For Bill

This week I filled out a set of 20" Budd brand wheels for myself. The Budd number is 48730-3. This is a late 1940s/early 1950s wheel having a Goodyear rim/ring design that would never have been fitted OEM to a Ford of the era because of the Ford/Firestone relationship. It was used OEM by Dodge and IHC. I have period NWRA references that list it for Ford but call it a "Changeover" wheel with no assigned Ford number. Yet, I also have a 2/61 Budd reference that lists it as number 8TS 1007-H. I find this number nowhere in period Ford Chassis Catalogs, and no OSI reference for it.

So to my question. Did Ford have some in-house secondary numbering system for such parts that is today unavailable to us? The letter "S" in the prefix and "H" suffix are way outside their normal numbering conventions and would seem to suggest such an explanation. Thx. Stu

8TS-1007-H is an invalid part number and my 1957/63 & 1964/72 truck catalogs: wheel manufacturer number to Ford part number doesn't list 48730-3

You may find part number(s) for this wheel in a Hollander Interchange Manual.

Look in your OSI catalog to see if there's an 8T-1007 or 8T-1015 or A8TZ-1007 or A8TZ-1015 .. I made these numbers up, but one (or more) might be correct.

The 48730-3 is catalogued by Budd through 1972, and I have the Dodge and IHC cross reference numbers. What puzzles me are the odd S in the prefix and H suffix. Where in Ford's inner sanctum do they come from? Thought you might have seen something to explain it. Thx. Stu

The "Ford" part number provided by Budd cannot be correct, unless it's a tractor number.

I don't have a tractor parts catalog.

Guess it could be there for an industrial application, or like you say for a tractor, but it's listed side-by-side with the correct (multiple agreeing cross citations) of the Dodge and IHC truck part numbers. I have found misprints in Budd references, as well as in NWRA references, but very few. The construction of the number is so unique it seems there has to be an explanation somewhere. Stu

Just saw your edit. I have OSIs for 9/51, 7/53, and 1/55. The 1007 grouping didn't exist in 1951 so it has nothing to shed light on this.

The 7/53 OSI has several changes related to moves from the 1015 group into the 1007 group. The only thing that catches my eye here is the 21TS 1015 that was obsoleted with no cross to a new number.

The 1/55 OSI continues the above trend but also lists a change of 7RT 1007-B to 8TH 1007-A. This and the above 21TS 1015 are the only changes involving an "S" or an "H".

My books don't cover far enough to the present to get to your A8TZ numbers. Stu

1007 listed in the '49/59 car parts catalog. I didn't look in the truck parts catalog, as I made those part numbers up "off the cuff."

The 1/51 truck Chassis Catalog is silent to the 1007 group, and it first appears in the 1/52 Chassis Catalog for big truck applications. Then it grows to cover all models in the 3/53 and 1/54 catalogs. Stu

Probably not what your looking for but I found in my Canadian master catalogue:

8TS-1015-F - 1955/56 F-B500 18"x7.50"

The matching lock ring is 8TS-1099-F.

Hmmm...Canadian parts catalog, I forgot I had one for 1953.

8TH-1015-A .. 20" x 6 1/2" Wheel - 1953 F/M500/600 front and dual rear wheels - use with 7.50" x 20" & 8.25" x 20" tires.

Ah ha, maybe that's the explanation. Canadian specs vs US specs. Budd would probably have supplied Ford of Canada same as Ford US and numbered for each market. As I think to other examples, I know for certain that K-H of Canada had their own unique numbering system distinct and separate from US numbers. Thanks. Stu
