Model T Ford Forum: Forum 2017: How many disks in very early clutches

The normal T clutch has 13 large disks and 12 small ones.
I have pulled my 09 transmission apart and I find 13 large, 13 small and one thick disk.
How many should there be when the motors were originally assembled?

That's right for early clutch packs, 13x13 + the thick one, very important that it go's in first.

Great.
Mine had a large in first, then the thick one and then alternate large and small, at least as far I could see. Iím sure abut the large was first as it was trapped into the Brake drum.

Someone in the past may have installed the newer style brake drum that did not require the thick disk.

Tony, then I could be wrong, that combination sounds even better, the problem was if a small thin one went in first, that could slip in-between the clutch drum and brake drum, jamming up and there fore losing a neutral.

Thinking about it, there should be a large disk at the rear end where the spring ring pushes on the clutch plates. If there is a small one in that location, the ring will become part of the clutch and wear. So there has to be a large one at the rear ended of the pack. The same is true at the front end of the pack, so there has to be one more large plate than small plates.
Now I have 14 small and 13 large so something seems wrong :-(.

The ones I have are 3 disks thick. The thick one was used on the early drums with the hat type bushing.
