All up & running after way too many hours of trial & error. The cause of my initial problem was in the control box, where the reverse relay stuck, overcranking the gripper past it's stop point. At that point, the #1 & #3 Micro switch roller arms were bent badly, and the gripper release gear, cranked too far, slipped off its alignment with the turnover gear on the shaft. Regarding my question in this post about reassembly of the gears, my best advise would be to NEVER take it apart! In this case, the release gear only needed to be turned by hand far enough to retract the spring-loaded inner gripper, then the shaft rotated a tooth or so to realign. No dis-assembly required. I wish I'd know that in November, but that's one way to learn. If the gears are both off, you'd replace the turnover gear, then work the gripper assembly both ways to check position. Trial & error, yes, but there aren't that many different combinations with just that one gear. Then the release gear is replaced with the gripper bow nearly straight up in the air. Again, work the gripper both ways to check for proper alignment. When the gripper if fully retracted over the magazine, the roller on #1 Micro should be in the cam notch. When it's fully retracted over the turntable, the #3 Micro roller will be notched. Along the way I learned that if Micros don't look right, even if they test correctly, they probably won't work. Now I'll have to take a good look at that control box, as I've taken one off a perfectly good 474 to get this 459 going.
