The Stovebolt Site Forums The Shop Area Engine Shop Yet another Bellhouseing question

Existing situation.
1954 Rebuilt motor with a bellhouseing that was gifted to me from a friends yard. The bellhouseing has the three bolts for the 1946 pedel / clutch mount. Pedels mount correctly. With the recent posts its my understanding their are several bellhouseing that the 1946 pedels can mount to. How is it possible to tell which bellhouseing to use when installing a T-5 trannie. Car?, Truck? Motor mount type? My 420 trannie bolt pattern is not the same as the bell and am wondering if the adapter thats used for the T-5 is made for several different bellhouseing. Does this make sense? Thank you.

The 37-40 bell housings were basically the same. The clutch fork ball was mounted further away from the tranmission hole on the 37-40. On the 41-46, the clutch fork ball was mounted closer to the center of the bellhousing. So even though both pedals mounted to the same three holes on the bell housings, and the clutch and brake pedal bracket are the same for all years, the set up is slightly different in the geometry of the pedal travel, especially the brake pedal. In other words, the 37-40 used a different clutch fork. Consequently, the 41-46 adapter made by Steve@Buffalo is not exactly correct for the 37-40, but I'm not sure Steve is aware of that. The adapter plate he sent me was a 41-46 adapter, but I made it work for my 37 by filing the hole out so it was larger and closer to the center of the adapter transmission hole.

I would say, if you use the 41-46 TRUCK bell housing adapter plate from Steve@Buffalo, you will be on the right track. To ease you mind, a short conversation with Steve would be a good idea.

Good luck!

If you use a 41-46 bellhousing (truck), you will have to use an adapter plate like steppinwood did in his tech tip... installing a t5 in an art deco truck. If you use the the later bellhousing... 48-54, you will need to fabricate a pedal mount. This bellhousing will bolt up to the t-5, but you will need to do further modifications to the transmission to gain the appropriate amount of clutch travel.

I would use a spacer plate rather than shorten the input shaft or extend the splines. That way you don't have to modify anything if you need another transmission.

Did any of the bellhouseings after 1946 have the clutch / brake pedel mounting holes?

Only the First Series 47 truck, which was actually a 46 truck.
