pilot bearing
« on: December 10, 2015, 03:10:47 PM »
I read it somewhere But now I can't find it . Iam looking for the size of the O.d. of the bearing for a 65 engine. Also does any one know if the material is standard brass or an alloy?

This should help, looks like brass with steel insert.

Dorman products makes one that fits well:

Dorman # 690-035
1.716" OD
0.594" ID

Originally designed for a Chev with a powerglide to adapt a manual trans. As far as I can tell it's bronze.

Prices start at $5 each for a box of 5 ($25)  from Rockauto, $10 each from Amazon, or up to $40 each from other places!

I believe pilot bushing are made of oil impregnated bronze, or at least they used to be.

Sorry, I read the bottom of the chain of posts and thought it was the last one. It is a little late and I guess I am tired.

No problem Kurt. Being oil impregnated makes cents . I have a bunch of brass stock ,but for the price and availability I can't make them for that. But someday I might just because I like to do that stuff.

If I remember correctly Buick used a steel adapter & had a roller pilot bearing installed into that.

Originally, they used an adapter to fit the crank, then the bushing pressed into that.
I don't think they used a roller bearing, but that could be a nice upgrade!

If you have a lathe, you could bore out the 690-035 bushing and insert a 690-057 roller bearing.

Yup I could ,But I think I would just make the adapter. That 690-035 does it go with the flange in or out?

Been a long time since mine went in, but I think it was flange side in - flat side out and flush.
