I have been known to turn a seal around backwards or put a spacer behind it or something like that to get the lip to run on a smooth part of the shaft. Yes, I know seals are best at sealing from the proper direction, but if there's not much pressure, such as in a gearbox, they'll usually do better running "backwards" on a smooth part of the shaft than the right way on a rough part. I've got a front axle shaft on a deuce that I did that to, and it's holding up okay.

I suppose the JB's better than nothing, but I used JB on 3 things that I thought it should have been able to hold and it failed in every case. I used to use Titan metal-filled epoxy and it worked vastly better then JB, but it's no longer made. Another option would be to build it up with soft solder and file it smooth, since that wouldn't require enough heat to kill the temper. Might also be feasible to find a seal with a slightly smaller ID and turn the yoke/shaft down to fit, much like you'd grind a worn crank undersized.
