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 26) from belt cover (B
B). Remove belt cover.
3. Loosen nut on idler pulley (A
A, Figure 27) 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 27). 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 26). Tighten screw (A
A).
7. Attach the spark plug wire.
NOTE: Whenever belts are adjusted or replaced, the cables
will need to be adjusted (see “Check and Adjust the Cables”
section).
