Does anyone pour babbitt in original cam bearings?
I have a bunch of them and and would trade for some that have new babbitt and are machined.

The problem with many old shells is that the parting line is worn and pounded so that the shells are not round anymore. Repouring them cannot fix this issue. Just something to consider when going down this path.

Apparently the new ones, or at least some of them, are also out of round. Mike Bender uses this to make them round.

It will likely cost more to re-babbit the old ones than to buy already made new ones. You still need to inspect the new ones though. The front ones may be too long, and I have had one too small on the OD.

Hope this helps.

Pressing a distorted out side into a round shape, will also distort a straight bored Babbitt inside.

The bad part lines, we pitch. We only spin pour the ones that have good Key.

Also, we always add more key to the inside of the bore, so the Babbitt will never let go.

We put a Babbitt thrust on the front ones.

It is not a copy Dan, I stole it from a Chevy rebuilder. They used it to crack walnuts!!!!!!!

Herm.

Nice job on the front Herm. Ford should have done them like that with a thrust surface.
