Brake Puck
A
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 35.
10.
Slide the washer onto the hex screw removed earlier 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.
lbs. to secure the auger pulley assembly on the input shaft.
12.
If also replacing the drive belt, proceed to the "Drive Belt" instruc-
tions. 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" from the As-
sembly 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" instruc-
tions in the previous sub-section.
1.
a. Pull the idler pulley away from the backside of the drive belt to
relieve the tension. See Figure 36.
b. Slip the drive belt off the idler pulley. Carefully release the idler
pulley.

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.
