Changing Friction Wheel
The rubber on the friction wheel is subject to wear and
should be checked after the first 25 hours of operation,
and periodically thereafter. Replace the friction wheel 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 screws from the frame cover underneath the
snow thrower. See Figure 6-13.
• Remove the right wheel from the axle.
• Using a 3/4” wrench, hold the hex shaft and remove
the hex screw and cupped washer and bearing from
left side of the frame. Refer to Figure 6-14.
• Holding the friction wheel assembly, slide the hex shaft
out of the right side of the unit. The spacer on the left
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 four screws securing the friction wheel to the
hub assembly. See Figure 6-15. Discard old friction
wheel.
