manual shift bell housing differences
Posted by: John Smith ()
Date: January 02, 2018 02:14PM

Hi there all, I am going to make a trip to a local guy that has a few extra bell housings for mostly early cars, There is a chance that in his collections could be a random late car bell. I may pickup a bell housing for my 64 4speed. Is there a differnce in the different yearts of stick shift bells? Thanks for any relevant input..It's been a few years since I have fiddled with these cars..

I am aware of the differences in a PG bell, I have two of those.

Looking at the corvair junkyard primer it’s 60-63 and 64-69 I assume due to cu in differences. The way to id a 60-63 is a shiny spot on the center of the bell housing?

So, are you saying a 145 cu bell may not work for a 164 block?

No idea for sure. I would think it would be the same, they just mean the dollar size spot in the casting is different?

At this point I am assuming that a manual bell may be usable for all years...any other input?

A 145 cu in bell housing will work on a 164 cu in engine. I just did that very thing. The 164 on the 145 the seal will rub on the slinger lip of the crank gear.

Make sure the seal is in the correct position...

A '65-9 164ci BH needs a spacer under the lip of the seal when used on a 145ci crankshaft.

If you need a lm bell housing, ask here and give your location. Lots of us have spares. Could be one close to you.

No it doesn't, I just did that very thing! I used no spacer. When you install the seal and then the bell housing look at the seal, the outer dust lip will just barely be riding on the crank gear bevel. That leaves almost a 1/16th inch clearance. Unless your crank end play is way out of spec that is more than enough clearance.

There is a casting number on the outside of the bell housings. The table below shows the application for these numbers.

Identification Numbers Cast in the Bell Housing

Manual Transmission Powerglide

1960-63 6256583 6255599
1964-69 3832176 3832517


Note that you can distinguish an early model flywheel housing from a late model one by the fact that the 1960-63 bell housing will have one or two concentric circles cast into the surface facing the cam gear. This surface, about one and one-half inches in diameter is also visible on the flywheel side too.


There were three types of crankshaft gears used in the Corvair production. The first (Type 1) was used on the 1960-63 engines. The second (Type 2) was used for all engines 1964-69, except the 140-HP engines with Powerglide. This last version (Type 3) was used only on the 140-HP engines, and 1968-69 engines all with Powerglide. The second and third types allow for [[size=x-large]b]a relocation of the large crankshaft seal, by moving it rearward by 0.070". (Required because of the new clutch in 1964.)[/b][/size]

Thanks for all the input on this topic. I will visit a local guy near me and see what he has for a bell. Wish everyone a great new year as we move forward.
