After a lot of hunting down , I ended up getting a set of clevite mains, as well as a set of King ones.

If the scaresage gets too bad they can always be whittled out on a lathe.

Re: 99a main bearings
Pete, I was going to look at fitting the 8ba centre and front mains but machine the small tag slot on the other side, and using the 81 rear main.

Re: 99a main bearings
I've used both Clevite as well as King bearings lately - both are high quality. I'm more concerned with bearing clearances than the brand . . . would not have a problem running most any of them.

Re: 99a main bearings
8BA and 59AB front and center main bearings are interchangeable. The rear thrusts are different.

Re: 99a main bearings
Are the 99A and 59A different? I know the centre and front are the same 59A and 8BA. The rears are different 59A/8BA.
So are 99A and 59A different? I put a 99A together but just reused the old bearings. |

Re: 99a main bearings
99A would be 39 Merc and they had 2.499 main journals, so think they would be the same.
