Friction Wheel Removal
If the snow thrower fails to drive with the drive control
engaged, and performing the drive control cable
adjustment on page 14 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
• Place the shift lever in third Forward (F3) position.
• Drain the gasoline from the snow thrower, or place
a piece of plastic under the gas cap.
• Carefully pivot the snow thrower up and forward so
that it rests on the auger housing.
1. a. Remove the frame cover from the underside
of the snow thrower by removing four self-
tapping screws which secure it.
b. Remove the right-hand wheel by removing
the screw and bell washer which secure it to
the axle.
c. Locate the hex shaft and E-ring on the right
side of the snow thrower frame, about two
inches from the wheel axle.
c. Using a suitable tool, carefully remove the
outer E-ring 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.
2. a. Slide the hex shaft downward and to the left
while carefully un-meshing the lower gears
on the hex shaft from the upper gears on the
wheel axle.
b. Set the hex shaft’s gears aside.
c. Carefully remove the inner E-ring from the
hex shaft and slide the friction wheel
assembly off the hex shaft.
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. Follow the steps above in reverse
order to reassemble components. If you’re
disassembling the friction wheel and replacing only the
rubber ring, proceed as follows:
3. Remove the four screws which secure the friction
wheel’s side plates together.
• Remove the rubber ring from between the plates.
• Reassemble the side plates with a replacement
rubber ring.
IMPORTANT:
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.
• Slide the friction wheel assembly back onto the hex
shaft and follow the steps above in reverse order to
reassemble components.
