The inner race should not be able to spin on the crankshaft .Its a very small lite press size for size deal in most cases.
I wouldn't use any locktite inside of my engines the heat and oils will more than likely break it down and it would be a band aid so to speak at best,plus if any got into the bearing itself it would be ruined.

Depending on how hard the crankshaft is and how far undersize ,it may be able to be knurled back up and turned down to the proper size and reused. If your interested in this repair PM me

Other wise a new Crankshaft will be in order
