SHEAR BOLTS (See Fig. 22)

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

shaft with a spacer, shear bolt and hex nut. Should a foreign 

object 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:

WARNING: To avoid serious injury, before

performing any service or ad just ments:

1. Be sure throttle is in STOP position.
2. Remove safety ignition key.
3. Make sure the augers and all mov ing 

parts have completely stopped.

4. Disconnect spark plug wire from 

spark plug and place wire where it 

can not come in contact with plug.

CHUTE DEFLECTOR

The chute deflector, attached to the top of the discharge 

chute, is provided to direct discharging snow away from 

the operator. If the deflector becomes damaged, it should 

be re placed.

WARNING: To avoid serious injury, 

nev er operate your snow thrower with 

the deflector removed or damaged.

• 

To change direction and/or distance snow is dis charged, 

see “TO CONTROL SNOW DISCHARGE” in the Op-

 er a tion section of this manual.

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.

CAUTION: Do not substitute. Use only original 

equip ment capscrew/shear bolts as sup plied 

with your snow thrower.

4.  Insert safety ignition key and reconnect spark plug wire 

to spark plug.
