6. Carefully remove the hex nut and washer which secures the hex shaft to
the snow blower frame and lightly tap the shaft's end to dislodge the ball
bearing from the right side of the frame. See Figure 36.
NOTE: Be careful not to damage the threads on the shaft.
7. Carefully position the hex shaft downward and to the left before carefully
sliding the friction wheel assembly off the shaft. See Figure 37.
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.

8. Follow the steps above in reverse order to reassemble components.
9. Perform the test previously described in the Drive Control section.
If you're disassembling the friction wheel and replacing only the rubber ring,
proceed as follows:
NOTE: Not all friction wheels are serviceable. If this is the case, simply replace the
friction wheel assembly.
1. Remove the four screws which secure the friction wheel's side plates
together. See Figure 38.
2. Remove the rubber ring from between the plates.
3. Reassemble the side plates with a new rubber ring.
NOTE: When reassembling the friction wheel assembly, make sure that the
rubber ring is centered and seated properly between the side plates. Tighten
each screw only one rotation before turning the wheel clockwise and
proceeding with the next screw. Repeat this process several times to ensure
the plates are secured with equal force (between 145-115 in-lbs).
4. Slide the friction wheel assembly back onto the hex shaft and follow the
steps above in reverse order to reassemble components.
5. Perform the test previously described in the Drive Control section.
