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 bolt 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:

eMove the throttle to STOP and turn off all controls..

eDisconnect the spark plug wire. Be sure all moving parts have stopped.

®Lubricate the auger shaft zerk titting (see the Main- tenance section, on pages 17-18)_

eAlign the hole in the auger with the hole in the auger

shaft Install the new shear bolt and Iocknut pro- vided

e Reconnect the spark plug wire

TO ADJUST TRACK

Ifthe snow thrower does not move forward evenly and the track slips slightly, you need to check the track as follows:

eMeasure 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:

eLoosen the bolts (See F{g 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 thetrack 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
