SiBVICE AND ADJUSTMENTS
TO REPLACE AUGER SHEAR BOLT
The augers are secured to the auger shaft with special
bolts (See Fig. 37) that are designed to break (to protect
the machine) if an object becomes lodged in the auger
housing. Use of a harder boll will destroy the protection
provided by the shear bolt.
IMPORTANT: TO INSURE SAFETY AND
PERFORMANCE LEVELS, ONLY
ORIGiNAL EQUIPMENT SHEAR
BOLTS SHOULD BE USED.
To replace a broken shear bolt, proceed as follows:
® Move the throttle to STOP and turn off all controls,
® Disconnect the spark plug wire. Be sure all moving
parts have stopped.
® Lubricate the auger shaft zerk fitting (see the Main­
tenance section, on pages 17-18),
® Align the hole in the auger with the hole in the auger
shaft install the new shear bolt and locknut pro­
vided,
® Reconnect the spark plug wire
TO ADJUST TRACK
If the snow thrower does not move forward evenly and the
track slips slightly, you rreed to check the track as follows:
® Measure the distance between the top of the side
plate and the inside of the track. The distance
should not be more than two (2) inches
If the distance is greater, you need to adjust the track, as
follows;
® Loosen the bolts (See Fig 38, A) on both sides of
the track assembly
® Turn the cam washers equally on both sides
® Adjust the track to reduce slack, so that the distance
between the top of the side plate and the inside of
the track is not greater than two (2) inches. Be sure
the cam washers are adjusted evenly or the track
will be twisted (See Fig 39) If the track becomes
twisted, readjust the cam washers to the correct
adjustment.
