DRIVE BELT ADJUSTMENT (Continued)

Adjusting Auger Belt Guide

1.With the auger control still fully depressed, adjust the auger belt guide(s) so that there is a 1/64” gap (1/32” Maximum) between the guide and the belt (Figures 28, 28a), 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 (Figures 28, 28a) to secure the guide.

3.Check the adjustment on the auger belt guide(s) (Figures 28, 28a) 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.

WARNING

Failure to properly adjust the Auger Belt Guide(s) may cause auger to rotate when Auger Control has not been depressed.

DRIVE BELT 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 transmits 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.

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 24) 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 29) 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).

WARNING

Snowthrower must move only when the traction Drive Control is depressed, and must stop when the lever is released (disengaged).
