1909 drive shaft and original rear bearing

[KimDobbins]

I'm posting some pictures of an original 1909 drive shaft, tube and original removable rear babbited rear bearing. The roller drive shaft bearing came along in 1910. Before that, the bearing consisted of a casting with a poured Babbitt center. It first was introduced it early 1909 in a smaller version, then increased in size later in 1909 to the version pictured here. This bearing proved unsatisfactory due to lack of lubrication by design, and lack of attention by the car owner and was changed in early 1910 to the Hyatt roller bearing. Also note that the pinion gear in 1909 was held in place on a straight, non tapered shaft by a key and was peeled in place, no nut was used.

Great pictures and it’s always a good day to learn something new especially when it’s T related.

Just a curiosity question, 1909 parts book show the pinion as 9/16" bore and 12 teeth then 1911/13 as 5/8" bore and 12 teeth.
The photo's above show 11 teeth pinion, was there options or parts book wrong?

For Keith,

Thank you so much for sharing the photos. Most of us will never personally be able to look at the inside of such an early T. The photos are the next best thing. Was the ring gear also riveted in place?

For Kerry,

Summary: It can be a little confusing sometimes. The pinion with 12 teeth you are discussing is the smaller one for the spider gears not the larger one for the drive shaft.

Additional details:

The pinion that fits on the drive shaft is an 11 tooth pinion (standard). It is called the Drive Shaft Pinion. The 1909 Drive Shaft Pinion that was peened (hammered over) in place was part number 2543 and was listed at $4.50 in the Jan 1909 Price List of Parts. The later Drive Shaft Pinion that was held on with a nut was part number 2597 and in the Apr 1910 Price List of Parts cost $4.50 and the price dropped over the years that followed.

The 12 tooth pinion you were looking at is labeled Rear Axle Pinion in The Price List of Parts book. It was part number 2524 and in the Jan 1909 Price List of Parts they were listed at $1.25. Those are the ones that fit on the rear axle spider and I usually call them spider gears, but that is not the term used in the Price List of Parts books.

For those of you who may not have easy access to a Price List of Parts booklet, if you down load the Free Lang’s Old Car Parts catalog, it usually has the same or similar part numbers as the Ford Price List of Parts. See: https://www.modeltford.com/item/2524C.aspx for the 2524C Differential Pinion Gears. Note for the computer search on their site – you need to be exact. When I typed in 2524 nothing came up. But when you look through the catalog it is easy to see it is 2524C etc. Also a Google search using 2524 Lang's Old Car Parts brings up the 2524C part.

Respectfully submitted,

Thanks Hap I see it now, that early set up must have been done away with early, the only pinion listed by 1911 is the tapered one, pinion only or shaft with a pinion.
