Friction Wheel Inspection (Models 2890 and 3090)
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 7-4.
4. Examine the friction wheel for signs of wear or cracking.
Friction Wheel Removal (All Other Models)
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.
Follow the instructions below. Examine the friction wheel for
signs of wear or cracking and replace if necessary:
1. Allow the engine to run until it is out of fuel. Do not
attempt to pour fuel from the engine.
2. Place the shift lever in first Forward (F1) position.
3. Carefully pivot the snow thrower up and forward so that it
rests on the auger housing.
4. Remove the frame cover from the underside of the snow
thrower by removing the self-tapping screws which secure
it. Remove the right-hand wheel by removing the screw
and bell washer which secure it to the axle. See Figure 7-7.
Figure 7-7
5. Carefully remove the hex nut which secures the hex shaft
to the snow thrower frame and lightly tap the shaft’s end to
dislodge the ball bearing from the right side of the frame.
See Figure 7-8.
NOTE: Be careful not to damage the threads on the shaft.
Figure 7-8
6. Carefully position the hex shaft downward and to the left
before carefully sliding the friction wheel assembly off the
shaft. See Figure 7-9.
Figure 7-9
NOTE: If you’re replacing the friction wheel assembly as a
whole, discard the worn part and slide the new part onto
the hex shaft.
7. Follow the previous steps in reverse order to reassemble
components.
8. Perform the Drive Control test on page 18 in the
Maintenance and Adjustments section.
