This is the crankshaft drive flange in my 1970 Olds W-31. I am trying to get a pilot bushing but none are the correct size. There is no snap ring groove either for a bearing
. I can get one machined at a local machine shop but am trying to figure out if this is actually the correct crank for this engine.

Is your car a four speed car or are you just adding the four speed? There is a correct roller bearing that fits the four speed cranks and it has to be staked after installing thus no retaining ring groove. I'm sure someone will chime in with the bearing number needed. I have one NOS in my shop but I do not have it in front of me.

Its a four speed.

Do you know the OD and ID of the roller bearing you have. I will have to measure mine to see if it will fit.

I can get that info tomorrow. And did it not already have a bearing?

smits

No it had a Dorman bushing.

Thanks that would be great help.

Why are you asking the same question you asked in your other thread? You will not get any different information no matter how many times you ask. The other thread has the information you need for the bushing number and the bearing number. Even newbies do not get different answers.

So I have tried the bushing and it did not work. I am just trying to find out what is the correct bushing/bearing for this crank.
