10. Slidethe hexshaft throughthe rightside of the frametowardthe
Idt sideand throughthe frictionwheelassembly.
11. After makingcertainthat the chainis on boththe large and the
smallsprocket,alignthe hex shaftwith the hexhub of the small
sprocket,and slidethe shaftthroughthe sprocket.
NOTE:If the sprocketfell from the snowthrowerwhileremoving
