Replacing Belts

NOTE: There are two belts on this snow thrower: an auger belt and drive belt. It is recommended that both belts be replaced at the same time.

1.Remove the spark plug wire from spark plug and ground it against the engine to prevent accidental starting.

2.Drain gasoline from the gas tank, or place a piece of plastic sheet underneath the gas cap to prevent gasoline leakage.

WARNING: Perform belt maintenance outdoors as some gas may possibly leak from the carburetor even though you placed a sheet of plastic underneath the gas cap to prevent the gas cap from leaking.

3.Remove the self-tapping screw shown in Figure 11, and press the plastic tabs to release the belt cover. Pull the belt cover up and out from around the engine and chute assembly. Set it aside and save.

Auger Belt

1.Slip the front auger belt off of the engine pulley pushing it forward and rolling in off of the pulley. See Figure 12.

2.Squeeze the auger control handle to release the auger brake, which is the tab that holds the belt onto the auger pulley. Remove the belt.

3.Replace with new belt after replacing the drive belt.

Drive Belt

NOTE: Replace the drive belt before reassembling the new auger belt.

1.Tip the snow thrower up and forward so that it rests on the auger housing.

IMPORTANT: Remember, gas could leak from the carburator at this point, the gas cap should have been covered with plastic as previously instructed.

2.Remove the spring that connects the transmission to a bolt on the engine frame. See Figure 13.

NOTE: It may be easier to first remove the flange lock nut, then use needle-nosed pliers to firmly grip spring and remove from bolt.

3.Pivot the transmission forward to release pressure on the drive belt. Remove belt from transmission pulley.

4.Remove the drive belt from around the engine pulley, and away from the unit.

5.Place the new drive belt into the groove on the engine pulley. See Figure 12.

6.Tilt the transmission forward and position the drive belt onto the transmission pulley.

7.Reconnect the spring to the bolt on the engine frame and secure the transmission. Reinstall the flange lock nut.

8.Install new auger belt.

9.Reassemble the belt cover on the snow thrower.
