Model T Ford Forum: Forum 2014: Rear hubs for a late 11 / early 12

If I recall correctly there is a difference with the rear hubs used in late 11 / early 12 with the clamshell rear end as compared to the common ones that came after..... I think it had to do with the length of the axle tube and interference when mounting the hub on the axles. Does anybody remember what the difference is, and if possible can you post pictures?

Thanks!

Hi Gary. I'm not aware of a difference and didn't notice any problems when assembling mine. I do know that the locating dimple for the bearing sleeve is in a different spot though.

Andrew.

I thought the thread area near the hub cap was different, the same as the front hubs. I could be wrong...

The rear hubs for the straight axles (1909 - about mid 1911) looked similar to the front hubs.

That straight hub was gone in very early 11. They did make a 6" straight hub for a short time during that last of the straight axle rear hub type but as I said it was gone in very early 1911 model year and I kind doubt seeing it in calendar year 1911. John Barr had those on his Touring car which he called a 1910 but it was built on October 9, 1910 and that technically would make it a very early 1911.

The late 1911 - 1916 rear hubs are just like later wood wheel hubs except they don't have Ford script. Some time about 1916 - 17 they started to have Ford script.

I thought there was a difference on the "inside" of the hub, something to do with interference against the grease retainer..... and if you used a later hub with the clamshell you needed to machine it off. I know there is a raised ring that centers the brake drum; I was thinking the raised area near the hole for the axle was not raised on the early tapered hub. I'd be glad to know I am wrong!!!

I have an early 1911 number 38,575 with the straight axle's and 6" hub. The hub is the same as the later one's but with the straight axle bore, not the tapered. The date on that would Feb. 16th 1911.

I have a set of 1912 rear hubs where the hub cap thread length is about 5/8", where another set (year unknown) have these threads only 5/16" in length. Curious whether this amounts to a marked manufacturing change, or simply variance between parts suppliers? Both sets have identical cast geometry facing the axle seal, and neither set has foundry hallmarks.
Regards,
Scott

Build sheet? I'm a relative newbie, that's the first mention I've seen of a Model T Ford build sheet, what does it look like and where did you find it?

All of the Mopars that I have restored in the past had one or more build sheets tucked under the rear seat or carpet.

Aren't they called Invoices and not "build sheets"? Dan
