It just came up through the dust seals.
I am going to try it again with a thicker grease when I get back to my shop.
Hopefully that will work.

Sorry buddy, but I had the same issue with one of my Novak bearings, and I had to cook the backplate until it went from black to bronze before the bearing got loose....After that, the bearing was garbage, but I installed a new ceramic bearing easily... Maybe the acetone could not get to all the glue, but the heat sure will... I would cook it until I smell the CA glue burning, then pull the bearing out while hot...

Okay, that's a good sign. You're on the right track.

Thicker grease is a good idea. I would suggest as well to hit the drift/pin with the hammer very very sharply (not hard, but very swiftly). That will create the shock pressure wave you need to pull the bearing out and should not allow enough time for the grease to squeeze through the seals. Make sure there's grease all the way to the top.

If you want to use niznai's method, then using 2.5million cst lube will make more sense, or using ofna diff lock lube....

It took a propane torch to get it out. But first, all the grease I had packed into it dripped out and landed on my fingers making nice blisters.
What a bad design. All they needed to do was make a through hole so you could drive the bearing out from the back side.

I think the New Novak motors have the hole in the back like you suggested... Sorry about the blisters, I have a few of mine too....lol........ I think that design was adopted to keep dirt out....
