The Stovebolt Site Forums The Shop Area Driveline Pilot Bearing / Bushing Question

I'm working on a clutch replacement and the pilot bearing in the clutch kit appears to be bigger than the old one. The old one is cracked and bad shape, it measures 1.04 O.D. and the new one measures 1.09. It appears that a standard size was used for many years, but the new one doesn't want to go in, do I just need a bigger hammer? I'm not sure how tight of a fit it should be.

For further info if needed, I've got a 235 out of a 53' Bel air in a 46' 1/2 ton with a 3 speed. Thanks for any insight.

Did your '53 235 come out of a Belair with a Powerglide?

If so, the '53 235 car engine with a Powerglide did not come with a pilot bushing. The crank for that particular year engine with the Powerglide is an oddball in that it is the only year/tranny combo for a later model 235 that will not accept a 'normal' pilot bushing. The good news is that the crank will accept the slightly-smaller-than-normal pilot bushing that has the correct ID for a manual transmission input shaft. They are available, just takes some research. I picked one up a few months ago at either Autozone or O'reilly, not sure which one. I think it was a Dorman part number. I'll see if I can find the number.

Yes, it is a power glide. I knew something wasn’t adding up. Thanks for the info, it saved me a bit of research, now I don’t have to go looking at the O.D. of all the different options out there and can get back to work. Thanks!

Ok gentlemen, the dorman 690-034 is still too big. Does it need a little persuasion? Are there other options or does it need machined?

Put it in the freezer for a few hours and try it again.🛠
