Belt Adjustment - Craftsman C950-52843-0 Owner's Manual

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 screw from belt cover. Remove belt cover (see
Figure 35).
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
(12.5 mm) with moderate pressure (see Figure 36). You may
have to move idler pulley more than once to obtain the correct
tension.
6. Release auger control. Auger must stop within 5 seconds.
7. If auger does not operate properly, stop engine and recheck
drive linkage adjustments.
8. Reinstall belt cover.
9. Whenever belts are adjusted or replaced, the cables will need
to be adjusted. (See "Cable Adjustment" in this section of the
manual).
10. Attach the spark plug wire.
