Figure 21
• Remove and replace auger belt inside belt keepers.
• Reassemble pulley to auger housing with hex bolt
and bell washer (cupped side toward the pulley).
Make sure key is in place on shaft and brake puck
is seated in the pulley groove.
• Reassemble the belt cover and chute directional
control.
Proper Adjustment: With the auger control in the
disengaged position the top surface of the new belt
should be even with the outside diameter of the pulley.
• To adjust, disconnect ferrule from brake bracket
assembly and thread ferrule in (towards idler) to
increase tension on belt, and out to decrease tension.
NOTE: The brake puck must always be firmly seated in
the pulley groove when the auger control is in the
disengaged position.
Drive Belt
• Unhook the extension spring from the belt cover
plate. See Figure 22.
• Remove drive belt from the engine pulley and
bottom drive pulley. Refer to Figure 22.
Figure 22
• Replace belt and reassemble in reverse order.
• Reassemble the two halves of the unit hooking the
lower portion of the auger housing over the
stationary shoulder bolts in the frame assembly.
• Secure the two halves with the two bolts and lock
washers removed earlier. Refer to Figure 18.
• Attach the “Z” fitting of the cable into the brake
bracket assembly. Refer to Figure 20.
• Slip the auger control belt over engine pulley.
• Insert ferrule on auger idler rod into bracket
assembly and secure with flat washer and cotter
pin. Reassemble the large shoulder bolt and lock
washer as shown in Figure 19.
• Reassemble belt cover and chute directional
control.
Changing Bonded Friction Wheel
The bonded friction wheel is subject to wear and should
be checked after the first 25 hours of operation, and
periodically thereafter. Replace the bonded friction
wheel if any signs of wear or cracking are found.
• 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 six screws from the frame cover
underneath the snow thrower.
• Remove the left wheel from the axle.
• Using a 7/8” wrench, hold the hex shaft and remove
the hex bolt, bell washer and bearing from left side
of the frame.
• Holding the friction wheel assembly, slide the hex
shaft out of the left side of the unit. The spacer on
the right side of the hex shaft will fall and the
sprocket should remain hanging lose in the chain.
See Figure 23A.
• Lift the friction wheel assembly out between the
axle shaft and the drive shaft assemblies.
• Remove four screws securing the friction wheel
assembly together. See Figure 23B.
• Discard old bonded friction wheel.
• Reassemble the new bonded friction wheel to the
friction wheel assembly, tightening the four screws
in rotation and with equal force.
• Insert the pin from the shift arm assembly into the
friction wheel assembly and hold assembly in
position. See Figure 23A.
• Slide the hex shaft through the left 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. See Figure 24.
