Maintaining
Your Snow
Thrower
WARNING
The rubber on the fric-
tion wheel is subject
to wear and should be
checked after the first
25 hours of operation,
and periodically
thereafter. Replace
the friction wheel
rubber if any signs of
wear or cracking are
found.
• Lift the friction wheel assembly out between the axle
shaft and the drive shaft assemblies.
• Remove four screws securing the friction wheel rubber
between the friction wheel plates. See Figure 33.
Discard old rubber.
• Reassemble the new friction wheel rubber to the
friction wheel assembly, tightening the four screws
in rotation and with equal force. It is important to as-
semble the rubber on the friction wheel symmetrically
for proper functioning.
• Insert the pin from the shift arm assembly into the
friction wheel assembly and hold assembly in position.
Refer to Figure 34.
• Slide the hex shaft through the right side of the
housing and through the friction wheel assembly.
• Insert the hex shaft through the sprocket and the
spacer. Make certain that the chain engages both the
large and the small sprocket.
NOTE:
If the sprocket fell from the snow thrower while
removing the hex shaft, place the sprocket on the hex
shaft. Position the hex hub of the sprocket toward the fric-
tion wheel when sliding the sprocket on to the hex shaft.
• Slide the bearing onto the left end of the hex shaft and
press into the hole on the left side the frame.
• Secure with the cupped washer and hex bolt removed
earlier.
• Secure the frame cover with self-tapping screws.
Put the snow thrower down to its normal operating
position.
NOTE:
If you placed plastic film under the gas cap, be
certain to remove it.

• Drain the gasoline from the snow thrower,
or place a piece of plastic under the gas
cap.
• Tip the snow thrower up and forward, so
that it rests on the housing.
• Remove screws from the frame cover
underneath the snow thrower. See Figure
16.
• Remove the right wheel from the axle.
• Using a 3/4” wrench, hold the hex shaft
and remove the hex bolts and cupped
washer and bearing from left side of the
frame. Refer to Figure 32.
• Holding the friction wheel assembly, slide
the hex shaft out of the right side of the
unit. The spacer on the left side of the
hex shaft will fall and the sprocket should
remain hanging lose in the chain.
