I love success stories like this. Congratulations. 9 out of 10 people would say send it out for a CLA or buy another camera, but if you have any mechanical ability at all and a little common sense (and maybe a little luck), mechanical camera repairs can be accomplished, and you get the reward of a job well done afterwards.
As for me, I'm still w/o a ball bearing for the 135 2.8 Soligor lens I took apart. It didn't fall on the floor, it accidentally got put it in the wrong place and I can't get it back out! The lens still works fine, but alas, no clicking detents on the aperture settings anymore. I just think of it as a Soviet Jupiter 11 lens and go w/ it.
