Model A hub on Model T

Post by BillyBobsSpeedShop » Mon Jun 29, 2020 6:41 pm

I am thinking of adapting Model A hubs to my model T spindles and understand that there are multiple ways to achieve this and curious what others have done. I had a great conversation with Tom Carnegie today in regards to what he has done in the past and curious if others can share what they have done.

Thanks

Do a google search ‘model A to model T wheel adapters’. You will find past MTFCA posts and lots of pictures on Google and different type of adapters. Some home made and others that are sold from T parts suppliers. The ones made now have gotten higher in cost. Others will have information how they made their own. Good luck.

I have a really nice set of 4, 2 piece design ones for $290.00 with shipping that mount on wood hubs.

The A spindles are about an inch shorter than the T. So you will need to machine the bearing register and thread back to support the bearings, then drill and cut off the remainder. May need to weld up a few low spots too...

Kevin good info.

I also read that you can install a 1/2 inch spacer on the spindle and the install the hub and bearings and there isnt any cutting or rethreading needed?

This is not to slight anyone who has responded, but you're not going to get much better advice than you have already gotten from Carnegie.

What is your end game, here? Do you percieve that "A" wheels are going to be superior to "T" wheels? Knowing what you're trying to really accomplish may lead to advice that would not otherwise have come forward.

Well I am currently in the process of building a speedster out of a 26 roadster. I am planning on running a Model A rear with model A brakes and couple it to a jumbo giant transmission that will be coupled to my T motor. Plan on using a a T frame with the Z brackets in the back with Model A split wishbones in the front with the front spring mounted to the wish bones for a spring behind setup. Also changing the steering out to mixture of a willys knight steering column and box and model A steering.


So I plan on adapting the Model A hubs to my model T spindles, ive got the bearings figured out as a inner model A bearing will work with SKF 17387 seal, the outer bearing will be the stock model T.

Two options that I know for the Hub adaption is the 1/2 spacer on the spindle, from what im seeing there will be no modification to the T spindle needed. The other option is tapering the t spindle a little more and lengthin the thread on the spindle along with extending the key way, drilling a new cotter pinhole and cutting a 1/2 off the end of the spindle so a hub cap can be ran on the car.

Thanks

With the Model A hubs installed on T spindle, you will need to use the Model A inner bearings so watch the machined area where the bearing rides with the 1/2" spacer installed. The bearing should fully be seated on that area. The spacer will need to be locked or tight fit on the spindle so it does not spin with the wheel, this will be were the seal rides. Somewhat like installing some later juice brakes on Model A's that use a spacer. While the Model T outer bearings work with the A hubs, the inners do not.
I know the voices aren't real but damn they have some good ideas! :shock:

Another option which I have done is to make new spindles that accommodate the brake backing plates and your hubs.
