4. Usinga 3/4" wrench,hold the hex shaftandremovethe hex
screwandbellevillewasherand bearingfromleft sideof the
frame.Referto Figure32.
5. Holdingthe frictionwheelassembly,slidethe hex shaftoutof
thefrictionwheelassemblyandthe rightsideof the frame.The
spaceronthe left sideof the hex shaftwill fallandthe sprocket
shouldremainhanginglosein the chain.
6. Lift the frictionwheelassemblyout betweenthe axle shaftand
thedrive shaftassemblies.
7. Removefour screwssecuringthe frictionwheelto the hub
assembly(referto Figure33). Discardold frictionwheel.
8. Reassemblethe newfrictionwheelontothe hub assembly,
tighteningthe fourscrewsin rotationandwith equalforce.It is
importantto assemblethefrictionwheelsymmetricallyfor proper
functioning.
9. Repositionthe frictionwheelassemblyin the snowthrowerframe.
Insertthe pin from the shiftarm assemblyintothe frictionwheel
assemblyandholdassemblyin position.Referto Figure34.
10. Slidethe hexshaftthroughthe rightsideof the frametowardthe
leftside and throughthe frictionwheelassembly.
11. Aftermakingcertain that the chainis on boththe largeand the
smallsprocket,align the hexshaftwith thehex hubof the small
sprocket,andslidethe shaftthroughthe sprocket.
NOTE:If thesprocketfellfromthe snowthrowerwhile removingthe
hexshaft,placethe sprocketon thechain.Realignthe sprocketon the
chainwiththe hexhub facingthe rightsideof unit.Positionthe hex
hubof the sprockettowardthe frictionwheelwhen slidingthe sprocket
