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).
