BELT ADJUSTMENT

Traction Drive Belt

The traction drive belt has constant spring pressure and does not require
an adjustment. If the traction drive belt is slipping, replace the belt. See au-
thorized dealer.

Auger Drive Belt

If your snow thrower will not discharge snow, check the control cable adjust-
ment. If it is correct, then check the condition of the auger drive belt. If it is
damaged or loose, replace it (see authorized dealer).
1. Disconnect spark plug wire.
2. Remove screw (A A , Figure 25) from belt cover (B B ). Remove belt cover.
3. Loosen nut on idler drive pulley (A A , Figure 26) and move idler drive
pulley towards belt about 1/8 inch (3 mm).
WARNING: Do not over-tighten, as this may lift the
lever and cause the auger drive to be engaged without
depressing the auger control.
4. Tighten nut.
5. With the aid of an assistant, engage the auger drive clutch. Check ten-
sion on belt which is opposite idler pulley (B B , Figure 26). Belt should
deflect about 1/2 inch (12.5 mm) with moderate pressure. You may
have to move idler pulley more than once to obtain the correct ten-
sion.
6. Release the auger drive control lever. T T he auger must stop within five
(5) seconds.
7. If auger does not operate properly, stop engine and recheck drive
linkage adjustments.
8. Reinstall belt cover (B B , Figure 25). Tighten screw (A A ).
9. Whenever belts are adjusted or replaced, the cables will need to be
adjusted (see "Check and Adjust the Cables" section).
10. Attach the spark plug wire.

BELT GUIDE ADJUSTMENT

1. Remove spark plug wire.
2. Have someone engage the auger drive. This will engage auger idler
pulley (A A , Figure 26).

distance should be about 1/8 inch (3 mm).
4. If adjustment is necessary, loosen belt guide mounting bolt. Move
belt guide to the correct position. Tighten mounting bolt.
