Help finding Input Shaft Bearing for 3 speed

[dznucks]

I am going to try Applied, down south of the airport. I have heard they can match any bearing.

There was not a shim in either of the transmissions. i thought about finding a metric washer or something to shim the play between the bearing and the small c-clip. But that wont help the play between the inner side of the bearing and the input shaft. The larger C-clip keeps the bearing from going into the transmission. Since this new bearing is .040" shorter in that dimension, theres .040" play inside of the tranny.

I did find this on a buick forum. I may give 5speeds.com a call.

If you have the HD Muncie 3 speed, the GM designation for that is SM330. It has a 7 bolt side cover and is often confused with the much more common Saginaw (SM326) which it superficially resembles. As you have found out for yourself, its parts do NOT interchange with the Saginaw.

The .040" shim between the thinner bearing and the gear should be a workable fix, but I am surprised that your bearing house can't interchange the NDH number.

I actaully have two of the Muncie's and a Saginaw in the shop.

The two muncies were built several years apart and use the exact same bearing. That's why I find it hard to believe its not easier to find the right bearing for this tranny.
