4. Slide the belleville washer onto the hex lock screw
with the crown side of the washer toward the screw
head. Apply Loctite ® 262 to the threads of the lock
screw.
5. Insert the hi-pro key in the key slot of the auger input
shaft. Align the keyway of the pulley with the hi-pro
key, lift the brake bracket assembly, and push the
pulley fully onto auger input shaft.
6. Insert the screw, with washer (cupped side toward
the pulley), through the pulley and into the input
shaft. Torque the lock screw to 150 to 250 in. lbs.
Lower the brake puck into the pulley groove.
NOTE:
If also replacing the drive belt, proceed to the
“Drive Belt” instructions. After replacing the drive belt,
complete the following steps.
7. Slip the auger drive belt onto the engine pulley.
8. Pull the brake bracket assembly towards the cable
guide roller and insert the auger cable “Z” fitting.
Refer to Figure 6-7.
9. Insert the ferrule on the auger idler rod into the brake
bracket assembly and secure with the flat washer
and internal cotter pin. Check for proper adjustment.
Proper Adjustment
: With the auger clutch lever in the
disengaged position, the top surface of the new belt
should be even with the outside diameter of the pulley.
a. To adjust, remove the auger idler arm ferrule
from the brake bracket and thread the ferrule in
(towards idler pulley) to increase tension on belt,
or out to decrease tension.
b. The brake puck must always be firmly seated in
the pulley groove when auger control is disen-
gaged.
10. Reposition the belt keeper, insert the previously
removed bolt and tighten both bolts to secure.
11. Reassemble the snow thrower frame and auger
housing by performing the earlier steps in the
opposite order and manner of removal.
Drive Belt
1. Pull the idler pulley away from the backside of the
drive belt to relieve the tension and slide the drive
belt off the idler pulley. See Figure 6-10.
2. Roll the drive belt off the lower drive pulley.
3. Remove the belt from the engine pulley.
4. Install the new belt on the pulleys in the reverse
order and re-tension with the idler pulley.
5. Return to Step 7 in the previous section (Auger Belt)
to complete reassembly of the snow thrower.
