Main Case Main Shaft Assembly with Low Force 
Gearing

1.

Place the Main Shaft vertical and hold the noise in a 
vise or a pilot hole in a piece of wood.

2.

Install the first stepped washer. The stepped edge 
should be facing down so that it contacts the 4th/5th 
sliding clutch. Rotate the washer to lock it into place.
