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 Belt Replacement in this section of
the manual).
1. Disconnect spark plug wire.
2. Loosen screw (B, Figure 11) from belt cover (A).
Remove belt cover (A).
3. Loosen nut (D, Figure 12) on auger idler pulley (B)
and move auger idler pulley towards belt about 1/8
inch (3mm).
4. Tighten nut (D).
5. Engage auger drive clutch. Check tension on belt
(opposite idler pulley). Belt should deflect about 1/2
inch (12.5 mm) with moderate pressure see Figure
12). You may have to move the idler pulley more
than once to obtain the correct tension.
6. Reinstall belt cover (A, Figure 11) securing with
screws (B).
7. Whenever belts are adjusted or replaced, the auger
drive or traction drive controls will need to be
adjusted. (see Auger Drive or Traction Drive
Adjustment in this section of the manual).
8. Attach the spark plug wire.
9. Auger must stop within 5 seconds.
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 Belt Replacement.
Note: After adjustments are complete, make sure the
drive disengages when released.
