c. Place the new auger belt in the V-groove of the
auger pulley and place the pulley w/belt inside
the belt keepers.
Turn the pulley as necessary to align its three slots
7.
approximately with the posts of the pulley adapter, then
move the brake bracket assembly away from the input
shaft. While aligning the pulley slots and adapter posts,
push the auger pulley fully onto the adapter. Refer to
Figure 7-8.
NOTE: If the pulley adapter was removed with the pulley, align
the splines of the pulley adapter and auger input shaft, and push
the pulley and adapter onto the input shaft. Refer to Fig. 7-8.
Slide the washer onto the hex screw removed earlier and
8.
apply Loctite 262 to the threads of the hex screw.
Insert the hex screw through the pulley assembly and into
9.
the threads of the input shaft. Torque the hex screw to
250-325 in. /lbs. to secure the auger pulley assembly on
the input shaft.
If also replacing the drive belt, proceed to the “Drive Belt”
instruction. If not, reassemble by performing the previous steps
in the opposite order and manner of removal.
NOTE: Make sure to remove the piece of wood blocking the
impeller.
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.
To adjust, disconnect ferrule from brake bracket assembly
10.
and thread ferrule in (towards idler) to increase tension on
belt, and out to decrease tension. See Figure 7-4.
NOTE: The brake puck must always be firmly seated in the pulley
groove when auger control is disengaged.
IMPORTANT: Repeat the “Auger Drive Control Test” from the
Assembly section before operating snowthrower.
Drive Belt
If not already done, remove auger belt as previous
1.
instructed.
a. Pull the idler pulley away from the backside of the
drive belt to relieve the tension.
b. Slide the drive belt off the idler pulley. See Figure 7-9.
Carefully release the idler pulley.
Remove the belt from the bottom drive pulley.
2.
Remove the belt from the engine pulley.
3.
Install the new belt on the pulleys in the reverse order and
4.
re-tension with the idler pulley.
Reassemble your unit by performing the previous steps in
5.
the opposite order.
Changing Friction Wheel
WARNING:
Run the engine completely dry of
gasoline before tipping snowthrower.
Tip the snowthrower up and forward, so that it rests on the
•
housing.
Remove screws from the frame cover underneath the
•
snowthrower. See Figure 6-6.
Remove the right wheel(s) from the axle. See Figure 7-10.
•
Using a 3/4” wrench, hold the hex shaft and remove the
•
hex bolts and cupped washer and bearing from left side of
the frame. Refer to Figure 7-10.
