Wrong clutch

[rgtrough]

I think I bought the wrong clutch for my ‘66 k10 and now the throw out bearing doesn’t want to throw out. The old clutch disc shaft/spline extended about 1/2-3/4 of an inch on the flywheel side of the disc. The new one is the same on both sides. Extends just past the springs in the clutch disc. Anyone else experience this?

Thanks

I think there is a tall and a short throw out bearing. My new clutch came with a throw out bearing that was different than my old one - I don't remember which way - but I used the throw out that came with the clutch and all is good. Do a search on here for throw out bering and you will see the difference.

There is 2 different clutch styles with different throw out bearings. I didn't realize that until I swapped in a different engine with the different clutch that was in better shape.

The shorter bearing is for the 3 finger clutch, the taller one is for the diaphragm type

There’s actually 4 clutch styles.
3 wide finger type which is called a borg and beck. Usually used in 1 ton and up trucks.
3 small finger called a long style. Normally used in fords.
Flat finger diaphragm.
Raised finger diaphragm.
Flat finger uses a tall tob, raised finger uses a short tob.

A pic of what you got would help a bunch.

Thanks guys for the replies. These suggestions make sense to me. I will try to find a 1.125 id long throw out bearing.
