1. Slide the Pulley Mounting Shaft 'flats' first through the Bearing opposite the Drive Motor to a
position that extends the shaft approximately ½ inch past the bearing: continue to move the shaft
further in as additional parts are added.

Assembly onto the Pulley Mounting Shaft.

Pulley Mounting Shaft.
