Any tips?
I've unbolted the bottom bearing plate, so that's free. The upper bearing/motor shaft is not breaking free. I whacked on the shaft a couple of times and it moved a bit, however, I don't want to break anything.

when are you going to post an instructional on how to do that drink shaker mod? I so want to do that for my Super Jolly. my roommate has a dremel and all. I'd like to know how it might fit on SJ too.
Sorry about the motor rotor problem, I can't help you there. I would really like to get mine off just to clean the crap out that's under it. tried to get it out and had a hard time... decided it was probably safer to leave it in there. I'm sorry to hear you got another mickey-mouse SJ, Noll. at least you've got a nice Mini. I'd be screwed if mine were in bad shape, no backup.

I'm guessing you are trying to replace the bearings? I had to do the same thing in my Cimbali Jr. The problem is that you need a press, you can't do it by hand using home tools. I was lucky enough that the guy in the shop where I used to work was able to replace the bearings in his spare time, but it required using the press to remove the bearing, as well as putting the new bearing on.
Oh, by press I mean he used a 20 ton hydraulic press. As for the actual amount required to remove and replace the bearing, I don't know.

Hold on man, I'm going to make one for the SJ, step-by-step. I just want a full teardown and reassembly first.

Right, similar to a wheel bearing. Makes sense, but I wonder why the upper bearing/ motor shaft fit is so tight. That's usually a thousandth over, it's the bearing/hub fit that's a press-fit. I know, it's crusted with 10 years of coffee goo!
