I've had to take a few apart as they had grease that turned to wax inside the spring. It wasn't an easy repair and not one I'd recommend without trying the easy way for a few weeks.

The other question is..I have accessed the motor hoping to check the brushes and clean it up but haven't found my way in. Do you think I take these tiny copper leads off and remove the gold colored pieces? The brush cases are in there. Or should this thing pull apart if I add some muscle?

Woot! woot! SUCCESS! I finally got the detent button to move! Yes! *doing the dance of joy! NOW, I can move forward with this machine. It's taken so long now, that I forgot what I am even doing with this machine. I'm sure I need to work the button more to get it really loosened up. I thought it was fully poked out, but once I got it to push in, I found out it was not fully poked out either.
I will still need to change that camstack gear. I'm a little nervous about that.

OK. It's time to call it.

This is a no-go. Not gonna happen. I DID change out the camstack gear and thought all was going well. I moved forward with some cleaning, oiling, and went on to try and adjust the needle. THAT's a bear. But while still in the process of trying to loosten these age old screws holding the upright tower to the base I found that the OTHER gear is now cracking.
That upright gear is just more expense for a machine that has cost me too much already. I'm looking at a donor machine.
Rest in pieces.

I've never had a Bernina with two cracked gears at the same time. I wonder what the history of the machine was and if it was stored in some oven somewhere and then put in the freezer:< Sorry to hear it didn't work out. Donor machines are needed, and you may get an e-mail from me some day as I'm always on the hunt for Bernina parts.
