JAUCH MECHANISM CHIME CAM:
The chime cam , and the chime hammer drive gear, are held in place by
setscrews that have very sharp points on the end that is inside. When they are
tightened up , they make a disruptive gouge in the shaft; which is ok until you try
to resequence. Often the cam or the gear will slip back into those gouges when the setscrews are tightened. You will fight it for hours unless you find some way around
the gouges. Grind off the end of the set screws or replace them, and smooth the
shaft, then tighten the setscrews and the wheel or cam will stay where you put it.
