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
authorized dealer.
Auger Drive Belt
If your snowthrower will not discharge snow, check the control cable
adjustment. If it is correct, then check the condition of the auger drive belt. If it
is damaged or loose, replace it (see authorized dealer).
Auger Drive Belt Adjustment:
1. Disconnect spark plug wire.
2. Remove screw (A A , Figure 29) from belt cover (B B ). Remove belt cover.
3. Loosen nut on idler pulley (A A , Figure 30) and move idler 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 lever.
4. Tighten nut.
5. With the aid of an assistant, engage the auger drive clutch. Check
tension on belt which is opposite idler pulley (A A , Figure 30). 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 tension.
6. Reinstall belt cover (B B , Figure 29). Tighten screw (A A ).

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.
