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

way groove to lock the stepped and no-burn washers 
in place as the Main Shaft is built.

(depending on the model of the transmission) and the 
no-burn washer. Rotate the washer and push the air 
line through.
