Slide the washer onto the hex screw removed earlier
and apply Loctite 262 to the threads of the hex screw.
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.
If also replacing the drive belt, proceed to the “Drive
Belt” instruction. If not, reposition the transmission
frame back onto the auger housing. 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
