Friction Wheel Inspection

If the snow thrower fails to drive with the drive control engaged,
and performing the drive control cable adjustment fails to
correct the problem, the friction wheel may need to be replaced.
NOTE: Special tools are required and several components must
be removed in order to replace the snow thrower's friction wheel
rubber. See an authorized Service Dealer to have the friction
wheel rubber replaced or phone Customer Support as instructed
on page 2 for information on ordering a Service Manual.
To inspect the friction wheel, proceed as follows:
1. Allow the engine to run until it is out of fuel. Do not
attempt to pour fuel from the engine.
2. Carefully pivot the snow thrower up and forward so that it
rests on the auger housing.
3. Remove the frame cover from the underside of the snow
thrower by removing four self-tapping screws which secure
it. Refer to Figure 7-3.
4. Examine the friction wheel for signs of wear or cracking.
