Sorry, I kept mentioning the bore in the crank because of how common it is to have a pilot bearing in the crankshaft. The same applies, however.
It is repair machining philosophy. You want to make one piece that adapts and remains in place even if your wear part is replaced. Your wear part in this case is the ball bearing. So.... the OD of the ball bearing should be supported by your "bushing" that is an interference fit in the machined bore in the flywheel. Make the bushing from steel, give it a good interference fit in the flywheel, so it won't come out when you remove and replace the ball bearing. Proper support of this bushing upon R&R would still be prudent, however.
