pilot Bearing problem
I am working on restoring a 59 corvette. The block is a 283 cast in Dec 1958 (not original to the car). I bought a new clutch kit that came with a new pilot bearing.
The OD of the bearing is 1.094" but the hole in the end of the crank is 1.062. No way the new bearing is going in with a .032 press fit (I tried a little). I have put in pilot bearings before
but only in newer engines - - they tap right in. The beaaring that came out was 1.0625 OD. Looking at replacement pilot bearing for 283 engines they are all 1.094 OD.
What am I missing? Is the crank not from the engine? Should I buy another pilot bearing and turn down the OD to maybe 1.063?
Anyone had this problem?
Thanks for any suggestions
Reggie

This is what you need. These are for engines that started out as Powerglides but never received the enlarged bore required for a manual transmission.

I ordered the part just a minute ago.
I have no idea what this engine was is in. It was just sitting in a junk pile when I bought it so maybe it had a powerglide.
Thanks again,
Reggie
