WEBApr 19, 2020 · When the shifter sheeve moves upward to the unlocked position, it allows 31 ball bearings (M1006) to drop downward and inward which in turn allows the collet closer adapter (M1004) and collet closer nose (M1003) to move down enough to loosen the grip on the collet. There is nothing else going on in there.
