Does anyone know a source of main bearings for D3400 in a D2 3J? I have a couple bearings that the Babbitt is coming off. Or can you have these shells re Babbitt? Any advice?

Thanks.

The best bet is to find a good Babbitt shop and have them redone

There is a family owned business that I think is located in Louisiana. I spoke with them on the phone, when I was searching for pony motor rod bearings. If I can find their information, I will post it. Essentially, send them your shells and crank dimensions.

D5C, D4-7U, D2-5U, D2-5J
