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 “How To Replace The Belts” in this section.
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. Remove

3. Loosen nut on auger idler pulley and move auger idler pulley
towards belt about 1/8 inch (3 mm) (see Figure 39).
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. Have someone engage auger drive clutch. Check tension on
belt (opposite idler pulley). Belt should deflect about 1/2 inch

have to move idler pulley more than once to obtain the correct
tension.
