I need a part number if anybody knows it. I can't find it, looked through everything I have and that I could find on the internet and still can't find a part number for that bloody ball bearing. Would also like the Factory Number for it as well as the Factory Number for the differential gear axle retainer (the vendor number is shown). Also would like the factory number for the differential gear housing nuts too.
If any of you guys with TT's knows these numbers, I'd appreciate it if you could tell me, so I can add them to the drawing. This drawing is just the differential, the 1923-1927 Model TT Rear Axle Assembly adds this assembly to the housing and it's seals.

I believe it is number 1018.

These extracts may be useful too:

I would guess by the fact that some of the numbers are A and AA that this is from the 1928 parts book. The early AA worm drive had some parts in common with the TT.

Mark,

I have a book (re-print I believe) that has the same pages as those Adrian posted. On the cover it reads, "Model T One Ton Truck" but it also is dated "Effective March 15, 1927", so I'm thinking you're correct. It has the TT stuff, but some early AA is in there too.

Adrian...seems a lot of the of differential parts have AA numbers on them.
Made the changes.

Hi Martyn, I believe that the top picture I posted is an early parts book, but I don't have the pages with the descriptions.
I think the late date of the latter pictures must include the AA truck, which essentially used a TT rear axle for the first year or two before going to a crown wheel assembly (please correct that those in the know )

Are those pages out of McCalley's "Parts Book"? I'll have to go back and look through it again and see what else I can find. According to all those AA numbers, the end production date posted is 1927. Sooo, these are probably good for 23-27, but won't be any good for 18-22 model years. Going to have to find numbers for that one and then I can post it too.

Those pages are from:
