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.

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 27) 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
