DRIVE BELT ADJUSTMENT
(Continued)
Adjusting Auger Belt Guide
1. With the Auger Control still fully depressed, adjust
the Auger Belt Guide so that there is a 1/64” gap
(1/32” Maximum) between the end of the guide and
the belt (Figure 22c), making certain the guide is
NOT putting pressure on the belt.
2. Making certain the Auger Belt Guide does NOT
move while doing so, tighten the Auger Belt Guide
Screw (Figure 22c) to secure the guide.
3. Check the adjustment on the Auger Belt Guide
(Figure 22c) to make certain that the gap between
the belt and the belt guide is correct.
4. Disengage the Auger Control by removing the card-
board tube (or other means used to temporarily
secure the control.)
5. Test the unit by following the steps under the
“Checking Auger Belt & Belt Guide Adjustments”
above.

DRIVE BELTS AND REPLACEMENT
The snowthrower has two drive belts, one for the
Traction Drive—which transmits engine power to the
wheels, and a second for the Auger Drive—which trans-
mits engine power to the auger mechanism.
Each of these drive belts are of special construction and
should be replaced only with Genuine Replacement
Belts which match the original equipment belts. These
are available from your dealer. (See COMMON
REPLACEMENT PARTS at the back of this manual for
the correct part numbers for each of the belts.)
Traction Drive Belt Replacement
1. Disconnect spark plug wire and fasten it away from
the spark plug.
2. Remove belt cover.
3. Pull the traction drive belt idler pulley arm (See
Figure 22) away from the belt to relieve tension, and
slide the belt off the engine pulley.
4. Slip the belt off from around the traction pulley (See
Figure 23) and pull the belt out of the unit between
the auger pulley and the traction pulley (the lower
cover need not be removed for this step).
5. Reverse the procedure to install the new belt. Be
sure there are no twists in the belt, and that the belt is
properly seated in the pulley grooves.
6. Replace the belt cover.
CAUTION
Snowthrower must move only when the traction Drive
Control is depressed, and must stop when the lever is
released (disengaged).
7. Start the unit, and check the traction drive for proper
operation. See "Traction Clutch Rod Adjustment" for
adjustment procedures.
