Reply to "Reverse and the troubling stud"

With the ZF mounted to an engine stand, I manually put it into reverse. I then proceeded to unscrew the stud, 1/2 turn at a time, taking measurements of this gap.

If the stud was up against the reverse gear, and thus keeping it from fully moving into position where the detent could hold it in place, the gap would increase as the stud was unscrewed.

Guess what?

Thanks go out to Ron McCall, who knows his way around the ZF far better than I, for confirming this small gap increase is indeed enough to correct this problem.
