Friction Wheel Rubber
• Check the rubber on the friction wheel after 25
hours of operation, and periodically thereafter.
Replace the rubber if any signs of wear or
cracking are found.
• Drain the gasoline from the snow thrower, or place
a piece of plastic under the gas cap.
• Tip the snow thrower up and forward, so that it
rests on the housing.
• Remove six screws from the frame cover
underneath the snow thrower.
• Remove klick pin securing the left wheel, and
remove the wheel from the axle.
• Remove the four screws securing the left drive
cover to the frame. Remove the drive cover from
the side of the frame. See Figure 26.
• Holding the friction wheel assembly, slide the hex
shaft out of the left side of the unit. The spacer on
the right side of the hex shaft will fall and the
sprocket should remain hanging lose in the chain.
• Lift the friction wheel assembly out between the
axle shaft and the drive shaft assemblies.
• Remove the six screws from both sides of the
friction wheel assembly. Remove friction wheel
rubber from between the friction wheel plate.
• Reassemble new friction wheel rubber to the
friction wheel assembly, tightening the six screws
in rotation and with equal force. It is important to
assemble the rubber on the friction wheel equally
for proper functioning.

• Slide hex shaft through left side of the housing and
the friction wheel assembly.
• Insert the hex shaft through the sprocket and the
spacer. See Figure 27. Make certain that chain
engages both the large and the small sprocket.
NOTE: If the sprocket fell from the snow thrower while
removing the hex shaft, place the sprocket on the hex
shaft. Position the hex hub of the sprocket toward the
friction wheel when sliding the sprocket on to the hex
shaft. See Figure 27.
