IMPORTANT: TO iNSURE SAFETY AND PERFORMANCE LEVELS, ONLY ORIGINAL EQUIPMENT SHEAR BOLTS SHOULD BE USED.. WHEN REPLACING SHEAR BOLTS, BE SU RE TO REPLACE SHEAR BOLT SPACERS. FIG. 34 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 alt moving parts have stopped. TRACK DISTANCE SHOULDNOT BE GREATER THAN 2INCHES Lubricate the auger shaft zerk fitting (see the Main- tenance section, pages !5-16). o Align the hole in the auger with the hole in the auger shafL Install the new shear bolt and shear bolt spacer provided. Reconnect the spark plug wire. TO ADJUST TRACK Ifthe snowthrower does not moveforward evenly and the track slips slightly, you need to check the track, as follows: (A) CAM WASHER 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.. FIG. 35 If the distance is greater, you need to adjust the track, as follows:
............................... _0UT OF ADJUSTMENT .......... _r o Loosen the bolts (A) (See Fig.,35) on both sides of the track assembly o Turn the cam washers equally on both sides° O 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. 36). If the track becomes twisted, readjust the cam washers to the correct ad- justmenL -t----CORREC I FRONT VIEW FIG. 36 22
