Changing the Friction Wheel
The rubber on the friction wheel is subject to wear and should be checked after 25 hours of operation, and periodically thereafter. Replace the friction wheel rubber if signs of excessive wear or cracking are found.
1.Drain the gasoline from the snow thrower, or place a piece of plastic under the gas cap.
2.Tip the snow thrower up and forward, so that it rests on the housing.
3.Remove six
4.Remove the wheels from the axle.
5.Using a 7/8” wrench hold the hex shaft and remove the hex bolts and cupped washer and bearing from left side of the frame. See Figure 15. Hold the friction wheel assembly, and slide the hex shaft out of the unit toward the right hand side.
6.Remove the six screws from the friction wheel assembly (three from each side).
7.Reassemble new bonded friction wheel rubber to the friction wheel assembly, tighten the six screws in rotation and with equal force. See Figure 22.
