Friction Wheel Inspection (Model 3090XP)

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. See Fig. 7-8.

4.Examine the friction wheel for signs of wear or cracking.

Friction Wheel Removal (Models 2410, 2620 & 2840)
