SERVICE AND ADJUSTMENTS

SHEAR BOLTS (See Fig. 18)

AUGER SHEAR BOLTS
Both right and left-hand augers are secured to the auger 

shaft with a shear bolt and hex nut. Should a foreign ob-

ject or ice become lodged in the augers, the shear bolts 

are designed to break, preventing damage to any other 

com po nents. 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.  Remove safety ignition key and disconnect spark plug 

wire from spark plug.  Place wire where 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" shear bolt.  Install 1/4-20 

lock nut and tighten securely.

CAUTION: Do not sub sti tute. Use only original 

equip ment shear bolts as sup plied with your 

snow thrower.

4.  Insert safety ignition key and reconnect 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 

de signed to break, preventing damage to any other com-

 po nents. If impeller does not turn when auger control lever 

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

To replace the capscrew/shear bolts:
1.  Disengage all controls and move throttle control to 

STOP position. Wait for all moving parts to stop.

2.  Remove safety ignition key and disconnect spark plug 

wire from spark plug.  Place wire where it cannot come 

in contact with spark plug.

3.  Align holes in impeller hub with holes in impeller shaft 

and install two (2) new 1/4-20 x 1-5/8" capscrew/shear 

bolts. Install 1/4-20 locknuts and tighten securely.
