8 3/4 problem

No, those gears were used, I got them off ebay. Visually there was no defect in the gear set. BUT, I guess it can be just like a head or block, there could be a crack that fluxing could find that the eye can't.

True Daredevil, found before it ruined the case, but more importantly the sure grip unit, I do have another 741 case with a non SG unit that I could have used.
