9. Turn the pulley as necessary to align its three slots approximately with the
posts of the pulley adapter, then pivot the brake bracket assembly away from
the pulley groove. While aligning the pulley slots and adapter posts, push
the auger pulley fully onto the adapter. Refer to Figure 34. Ensure the brake
puck of the brake bracket assembly aligns and is fully seated in the pulley
groove.
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 Figure 34.
10. Slide the washer onto the hex screw removed in Step 6 and apply Loctite 262
to the threads of the hex screw.
11. Insert the hex screw through the pulley assembly and into the threads of the
input shaft. Torque the hex screw to 250-325 in-lb to secure the auger pulley
assembly on the input shaft.
12. If also replacing the drive belt, proceed to the Drive Belt Replacement
instructions. If not, reposition the transmission frame back onto the auger
housing.
13. Install the drive belt on the engine pulley, re-connect the auger cable
z-fitting and auger idler rod ferrule to the brake bracket. Reposition and
secure the engine pulley belt guard, and re-install the belt cover.
NOTE: Make sure to remove the piece of wood blocking the impeller.
Check the auger drive belt 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. Thread ferrule in
(towards idler) to increase tension on belt, or out to decrease belt tension.
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 on page 11 in the Assembly
section before operating snow thrower.
Drive Belt Replacement
If not already done, remove the auger drive belt from the front pulley of the engine
double pulley. Refer to Auger Belt Replacement instructions on page 23.

1. Pull the idler pulley away from the backside of the drive belt to relieve the
tension. See (A) in Figure 35.
2. Slip the drive belt off the idler pulley. Carefully release the idler pulley.
See (B) in Figure 35.
3. Roll the drive belt off the lower drive pulley. See (C) in Figure 35.
4. Remove the belt from the engine pulley. See (D) in Figure 35.
5. Install the new belt on the pulleys in the reverse order and re-tension with
the idler pulley.
6. Reassemble by performing the previous steps in the opposite order and
manner of removal.
Changing Friction Wheel
The rubber on the friction wheel is subject to wear and should be checked
periodically. Replace the friction wheel if any signs of wear or cracking are found.
1. Run the unit's fuel tank dry before performing Step 2. Do not attempt to
pour fuel from the engine.
2. Tip the snow thrower up and forward, so that it rests on the housing.
3. Remove screws from the frame cover underneath the snow thrower.
See Figure 36. Remove the right wheel from the axle.
