The Jett web site has the best info for bearing R&R in my opinion.
Much like ChrisAttebury and SeamusG do:
After the crank and prop drive is reinstalled , I put a spacer and a wavy washer where the prop would be, than a prop nut. I tighten just to put a tiny bit of pre-load on the assembly, NEVER TO PRESS IT TOGETHER! It is than put in the oven for 10 minutes at 300* than take it out to cool. This way there is no chance of the bearing races creeping away from the seats/shoulders as it cools. With no con rod on, the crank should spin loose with no noise. All it take is a tiny bit of lint or hair to mess things up.
I too, am done with
ceramic bearings.
