Re: 3D Model T transmission project - help needed

I have the general plans from the Henry Ford archives, but did not know there were more detailed plans available from Ford. May I contact you privately to ask who you spoke with at Ford for such info? Not sure I can afford the usage fees right now, but worth checking into. In the meantime, I will ju...

Thank you. This is a project full of ever changing details, as today pointed out.

I admire anyone who has attempted to recreate this transmission.

Re: 3D Model T transmission project - help needed

Okay, getting somewhere. Will add to my notes. Our discussion today has been very enlightening. Here is the back of my brake drum (thus far). I tried to match the photos of the drum we had. Having trouble IDing the Drive plate bolts. Says they are 3/8" x 13/16" - 16 TPI - coarse. Thanks again, Jim K...

Re: 3D Model T transmission project - help needed

Yes, it does. But, I am taking notes and will endeavor to make a plan that reflects what ideal O.E.M.

I suppose then, that shooting for 1920 is perhaps the best shot, or is it 1925?

Is this the correct Clutch disk drum?

Thanks again.

Re: 3D Model T transmission project - help needed

The earlier brake drum drum is what I am after. I was told they replaced the thrust bearing with 3 washers (.026", .042", .042") to create an .015" to .027" clearance. If 192something is what I am making, then so be it. I based the brake drum off ebay shots labeled 1912-1920 or so. I am not making t...

Re: 3D Model T transmission project - help needed

I based the 1915 on there being two bushings inside the brake drum shaft. Read they changed in 1916. Really no other reason. When did the starter and ring gear begin? I'm not opposed to dating this correctly, or altering the plan to make this correct. As to acquiring a Model T transmission to measur...

3D Model T transmission project - help needed

Hello everyone, After being away for several years, I have decided to renew my membership and return to this forum with what will hopefully be received as a interesting project, worthy of members help. Years ago I started a plan drawing of the Model T transmission, mostly because I wanted to know ho...
