Transmission-bell housing question
Recently I broke the Bell housing/ flywheel cover. I would like to replace the part but I don't know the size of my transmission. How do I figure this out OR how do I replace the old part without knowing the transmission size?
History-I just bought a 1968 c10 short bed. When the kid sold it to me he said it had a 283 engine, and that's about all I know. (I’m not even sure that is correct.) As you can tell I'm a little green at this but I do plan to learn my way around and get this truck rebuilt. I appreciate any help on the bell housing questions for now.....thanks |

Re: Transmission-bell housing question
You came to the right place for info.The 68 will have a bellhousing thatbolts to the frame on either side.IIRC all of them are the same.If you subscribe to the BB there are classifieds where you can look.I'm sure someone has a bellhousing that will fit.
BTW WELCOME to the besyt resource you will find for info on these trucks.

Re: Transmission-bell housing question
Be sure to check the size of the bearing retainer hole at the back of the bell, IIRC 67 and earlier was smaller and 68 up had the larger hole, someone here will remember the dimensions. Check the for sale thread, threre were two for sale on the same thread a few days ago, from the pics it kind of looked like one ws small hole and the other large hole.

Re: Transmission-bell housing question
'67 trucks with both 3-speed Saginaw and 4-speed SM420 used a bellhousing with a 4-9/16" diameter pilot bearing hole [GM p/n:3815891]. '68 [and later] 4-speed trucks used a bellhousing with a 5-1/8" opening [GM p/n:3925505].
Is it a 3-speed (shifter on column) or a 4-on-the floor? If it's a 4-on-the-floor, is Reverse to left [toward you] or right [away from you]? If to the left it's a 420, if to the right it's a 465. The bell housing is the heavy cast iron part on top. The flywheel cover is the sheetmetal guard on the bottom. Don't lose it, they're hard to get now. Did both break?

Re: Transmission-bell housing question
Awesom, thank you. It's a 3 speed on the column. The only part I broke was the bell housing--it was plastic.

Does the post-'68 Saginaw have the larger 5-1/8" diameter?
