Neither Lang's nor Mac's lists fan shaft bushings for the 1915.
Were they not used ?
Chaffin's lists 3974A bush for Steel Hub Fan 13-20. My 13 had a Brass Hub Fan, and I used their new pulley with sealed bearings listed for 09-19, also they show a Ball Bearing Conversion for the Steel Hubs
Hope this helps.
The brass hub WAS the bearing...
Just don't know if he has brass or steel hub he's looking for the bush for.
15 "should" be brass, so that is the answer - mine had a steel one on as the brass hubs wear pretty thin and finding good brass ones is getting pretty tough.
Bud would need to post pictures as the fan could be any year except maybe 26-7 and if he's looking for bushings it certainly is not a brass hub setup
You can bore out the early fan hub and install a bushing if you have a lathe.
I didn't realize that the 15's came with a brass bracket. Mine is obviously not brass and must have been changed out at some point.
Here is a picture (I'm dealing with an upper hose leak so ignore the mess !)
As I now understand it there are two bushing sets, 1917 thru 1920 and 1920 thru 1927.
Any easy way to tell which set I need?
The forum is a great place to find information. A quick comment – the bracket that holds the fan is NOT bronze or brass but is ferrous metal (I think it is forged but I do not know that for sure. But it will rust so it is not bronze or brass.)
The On Line Encyclopedia is also very helpful. At: http://www.mtfca.com/encyclo/F-H.htm#fan1 it has:
Similar fan assembly but tension screw now pressed against a boss at the pivot end of the arm. The cast-in “knob” on the fan bracket was discontinued around 1914-15. The fan hub was redesigned and to be made of malleable iron beginning in July 1915. However the older (bronze) hub continued into late 1916, both types apparently being used.
Similar to earlier type but hub was now cast iron. In 1916 (1917 cars) the fan bracket was changed to the longer and straighter type, which was used until the 1926 models. Early production 1917 cars used a fan shroud behind the radiator but this was apparently discontinued after a short time.
And Bruce’s “Model T Comprehensive Encyclopedia” has lots of good photos to help you with the ID process.
Below is a photo by Mike Panish of a bronze hub fan.
Below is a photo by James Lyon of a bronze hub fan.
Below is a photo of the Jun 1917 Rip Van Winkle Ford showing the cast iron hub (from the “Vintage Ford” May – Jun 1991 page 35, used by permission.) Notice how similar it looks to the previous Bronze hub. If they were both painted -- it would be hard to tell.
Below is a photo from e-bay showing the cast iron hub.
Note if you look at your hub where the fan belt has been running the paint should be worn off and you can easily tell if it is iron or bronze by the color. The fan and hub could be painted and from your photo I cannot really tell which material it is made out of.

Riveted fan blades mean brass hub, original brass hubs were assembled with the blades and then dipped in black paint, the only way you could tell that they were brass was when the fan belt wore off the paint!
If I were you and you want to keep the original brass look, I would go with the sealed bearing hub from Chaffin's, that's what I did.
You will also need to buy a blade set, and rivets. Make sure you can craft a way to buck the rivets when you assemble the parts.
Do it one time right, and you can forget about any future problems.
Hap's picture shows the 1916 - 17 riveted steel hub Ron.
Dooh! My bad, I was thinking the individual blades rather than the one piece blade assy.,not rivets! But it looks like I was wrong on that too!
Thanks for pointing that out Royce
