DRIVE BELT ADJUSTMENT (Continued)
If the auger drive slips (auger slows or doesn't rotate nor-
mally while blowing snow), or stays engaged when the
control is disengaged — and the auger clutch cable has
been properly adjusted — the auger drive belt may be
out of adjustment.
Checking Auger Belt & Belt Guide
Adjustments
1. Insert the engine key and start the snowthrower.
2. Engage and disengage the auger control a series of
ten times, checking that the auger comes to a com-
plete stop within 5 seconds after the control is disen-
gaged each time.
3. If the auger comes to a complete stop each time with-
in 5 seconds, the adjustment is correct. If the auger
does NOT come to a complete stop within the neces-
sary 5 seconds, the adjustment is incorrect: readjust-
ing the auger belt & belt guide according to the pro-
cedures below.
Adjusting Auger Drive Belt
1. Make certain that the snowthrower is off, the engine
key has been removed, and the spark plug discon-
nected.
2. Check that there is no slack in the auger drive clutch
cable (see Figure 26). If there is, follow the auger
drive clutch cable Adjustment procedure on page 24.
3. Measure the length of the auger drive clutch spring
(Figure 26).
4. Fully depress the auger control and measure the
expanded length of the spring.
The spring should expand 19/64”-5/16”. If the spring
deflection is less than 19/64”-5/16” the auger idler
pulley must be adjusted. Proceed to step 5.
5. Loosen the belt cover screws and remove the belt
cover (Figure 25)
6. Loosen the adjustment bolt (see Figure 27) and move
the auger idler pulley.
7. Tighten the adjustment bolt and repeat steps 3-4.
8. Test run the unit. The auger must NOT rotate unless
the auger control lever has been depressed. Proper
auger drive belt adjustments stop the auger within 5
seconds after the auger control is disengaged. If the
auger drive fails either of these tests, repeat the
adjustment procedures.
