I agree with Joe K (#6 post). Now is the time to correct the issue since it’s out. The shaft is going to turn in the pilot bearing as it has already so it’s going to wear smaller yet. As mentioned, getting it turned is easy for any machine shop. Also it seems most machinists have their own lathes at home and may do it for you. I’ve had them turned to 5/8” by a retired tool and die maker. The bearing originally was metric at 17 mm. That few thousandths will clean-up most shafts and has never been a problem strength-wise. You can buy bearings at most bearing shops. I get mine on Amazon Prime.
