TO REPLACE AUGER SHEAR BOLT
The augers are secured to the auger shaft with special bolts (see figure below) that are designed to break (to protect the machine) if an object becomes lodged in the auger housing. Use of a harder bolt will destroy the protection provided by the shear bolt. Your
replacement shear bolts are found in your tool box located on belt cover.

•Remove right side bearing plate. Leave hex shaft in original position.
•Remove friction wheel from hub. Slip fric- tion wheel oft hex shaft towards right side. See figure below.
•Position new friction wheel onto hub. See
Figure below.

•install bearing plates to original position. Ensure hex shaft is engaged with both bearing plates.
•Secure bearing plates, using bolts re- moved earlier.
•Secure friction.wheel to hub using fasten- ers removed earlier. Ensure hex shaft
tums freely.
•Should friction wheel require adjustment (see To Adjust the Friction Wheel on page 20).
NOTE: Ensure friction wheel and friction
disc are free from grease or oil."
•Replace bottom panel•
IMPORTANT: To ensure safety and perfor- mance levels, only originalequipment shear bolts should be used. When replacing shear bolts, be sure to replace shear bolt spacers.
To replace a broken shear bolt, proceed as follows:
•Move the throttle to O (STOP) and turn off all controls.
Disconnect the spark plug wire. Be sure all moving parts have stopped.
Lubricate the auger shaft by squirting Lubriplate or a fiber impregnated grease into the shear bolt hole in the auger shaft. Then rotate the auger to distribute the oil in the shaft.
•Align the hole in the auger tube with the hole in the auger shaft, install the new shear pin and spacer found in toolbox lo- cated on top of belt cover.
NOTE: Spacer fits inside the larger hole in the auger tube.
•Reconnect the spark plug wire.
TO ADJUST TRACK
it the snow thrower does not move forward
evenly and the track slips slightly, you need to check the track as follows:
•Pull up gently on the center of the track near the center.
•Measure the distance between the track
and the top of the track support frame
(see first figure on page 22). The
distance should not be more than one and
