Babbitt Bearings
Is there a vendor out there that will pour babbitt in main bearing caps on an exchange basis?

Re: Babbitt Bearings
I believe all babbitt places only do both the block and caps together. There aren't many places that still do babbitt as many shops now used inserts.

Re: Babbitt Bearings

Re: Babbitt Bearings
Bill Barlow from Bend Oregon does an excellent job. You send him your caps via USPS, with the measurements form the crankshaft, and with-in a week of him receiving your order, you have the three best pieces of jewlery in ever bought in your life. I have usd his bearings in engines, with absolute satifaction. Bearing caps come back machined to dimensions including shims at the correct thickness

Re: Babbitt Bearings
Question: How can you just have the caps poured and get a round bearing surface? It would seem that you would get 1/2 new and 1/2 worn.

Re: Babbitt Bearings
There is no way they will fit right, blocks are not bored on the exact center line on every engine. They will be close, they will have to be hand scraped to get full contact. Other wise you will have to adjust them often for a while. For those who say they did it and it ran great, good for you, but I bet you have not drove it many miles. It is possible to get real lucky. How do you mike the center mains when the crank is in the block, you might get close.

Re: Babbitt Bearings
Quite often, the bearing surface, including the thrust surfaces in the engine block,are in perfect, or next to perfect condition. Babbit might also be tight to the block.
If the bearing bores of the engine block are in alignment, and the crankshaft is true and straight, the crankshaft basically rides on the surface of the bearing caps. Especially during engine starting, run-up, and shutdown. That is why oil pressure to the mains is very critical, which without a full pressurized system, the "oil wedge" machined into the side of each main bearing babbit is critical to maintain as much oil lubrication as possible. Main bearing caps are "tinned" prior to the pouring of the babbit. The babbit in the engine block side, is poured into the engine block bearing pouring mold, and hammered tight against the bearing surface journal. The block bearing journals have 5/16' shallow holes drilled into each bearing saddle that hold the babbit. The engine block is not tinized to receive the poured babbit. Bill Barlow, is very particular on receiving very accurate measurements, of all main bearing diameters, and accurate measurements of the distance between thrust faces. Pictures of your crank, and condition of the babbit in the block, is without question of benefit to him also, for condition evaluation. Question then is; Why change the babbit in the block, when it is not reguired ? |

Re: Babbitt Bearings
If that were the case, all anyone would have to do is send their caps in and despense with sending the block in for work. I agree with George.

Re: Babbitt Bearings
I have also used Bill Barlow. He uses your old caps to make sure the alignment on the new caps he makes is matched. My situation is that the babbilt in my rear cap was cracked - every thing else was good. So far so good.

Re: Babbitt Bearings
How many ways can you say it George, Herm.
People that are not machinest, do not realize how much .002 is. The average hair is about .003 thick. Lets say they were only off the center line .002 then you would have a .004 gape if it was to one side. or if the crank was below center line the bearing would be to tight. Which you could shim for. Or if it was to high the bearing would be loose. Or to big across the top of the cap. I would bet there are a lot of engines out there off the center line more than .002, It is very hard to get it .0000 Herm I'm sure you get request for caps all the time, how does it work out for you.

Re: Babbitt Bearings
My rear main cap is crack right down the middle but all my other caps have I would say almost perfect babbitt on them. They look like they have very little wear on them so what should I do have them all done again. Sorry I am not trying to be a smart (a) but I don't no what to do. Richard/Ca

Re: Babbitt Bearings
Thank you very much for your great advice Herm. It will probably be to my advantage to have the block and all re babbitted since I want to keep it original. A man once told me (To do a job big or small do it right or not at all ) This is one of those times there is no other way around it. Thanks again to all. Richard/Ca.
