SHEAR BOLTS (See Fig. 20)

AUGER SHEAR BOLTS

Both right and left-hand augers are secured to the auger shaft with a shoulder/shear bolt and hex nut. Should a for- eign object or ice become lodged in the augers, the shear bolts are designed to break, preventing damage to any other components. If one or both augers do not turn when auger control lever is engaged, check to see if one or both of the bolts have sheared. To replace the shear bolts:

1.Disengage all controls and move throttle control to STOP position. Wait for all moving parts to stop.

2.Disconnect spark plug wire from spark plug and place it wear it cannot come in contact with spark plug.

3.Align hole in auger hub with hole in auger shaft and install a new 1/4-20 x 2" shoulder/shear bolt. Install 1/4-20 lock nut and tighten securely.

CAUTION: Do not substitute. Use only original equipment shear bolts as supplied with your snow thrower.

4.Connect spark plug wire to spark plug.

IMPELLER SHEAR BOLTS

 

The impeller is secured to the impeller shaft with two (2)

 

capscrew/shear bolts and hex nuts. Should a foreign object

 

or ice become lodged in the impeller, the capscrews are

 

designed to break, preventing damage to any other com-

 

ponents. If impeller does not turn when auger control lever

 

is engaged, check to see if the capscrews have sheared.
