So, I tried this, wicking grade thread locker, but it will simply not harden, or at least not make the shaft and inner bearing race stick together. I turned the engine on its side, cleaned it up with denatured ethanol and high pressure air, left it for a few hours, and then applied the threadlocker. Unfortunately, the bearing race still spins freely on the shaft, after several days of hardening.
It was suggested to me that Loctie 290 isn't the correct adhesive for this application as it's a thread locker, but rather that loctite 601 (wicking) or 603 should be used, which are shaft locking adhesives.
I did manage to spill some on the wrong side of the bearing race, but like ProCycle says, hopefully won't mean anything (like, it didn't harden anyway, so what could it possibly do...)
It sounds like you might have quite a bit more clearance between your shaft and the inner race of the bearing than I do. I can not spin the bearing race by hand on my engine without the shaft turning with it. I will try again tonight to be sure, but I'm almost positive that I can't. That being the case, you may have too much of a gap for it to cure properly.
I'm not sure that loctite 601 (listed as 609 in the US and 601 in the UK) is actually wicking adhesive. Per their website it seems like it is just a low strength shaft adhesive designed to take up clearances up to 0.006" but also be removable for maintenance. The 603 (which is still listed as 603 in the US and UK) is designed to do the same thing as 601/609 but it has higher strength and is more of a permanent solution. I do think that given your situation, one of these products is probably what you need.
