Augers
•
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. If you hit a hard
foreign object or ice jam, the snow thrower is
designed so that the bolts may shear.
Refer to Figure 13.
•
If the augers will not turn, check to see if the bolts
have sheared. Replacement shear bolts and hex
lock nuts have been provided with the snow
thrower. When replacing bolts, spray an oil
lubricant into shaft before inserting new bolts.
IMPORTANT:
NEVER replace the auger shear bolts with
standard hex bolts. Any damage to the auger gearbox
or other components as a result of doing so will NOT be
covered by your snow thrower’s warranty.
Shave Plate and Skid Shoes
•
The shave plate and skid shoes on the bottom of
the snow thrower are subject to wear. They should
be checked periodically and replaced when
necessary.
•
To remove skid shoes, remove the four carriage
bolts and flange lock nuts which attach them to the
snow thrower. Reassemble new skid shoes with the
four carriage bolts and flange lock nuts. See Figure
14.

Belt Removal And Replacement
Auger Belts
NOTE:
It is necessary to remove both belts in order to
change either one. If changing just one belt, be certain
to check the condition of the other belt.
•
Remove the plastic belt cover at the front of the
engine by removing the two self-tapping screws.
See Figure 15.
•
Drain the gasoline from the snow thrower, or place
a piece of plastic film under the gas cap.
•
Tip the snow thrower up and forward so that it rests
on its auger housing.
Figure 15
•
Remove the six self-tapping screws from the frame
cover underneath the snow thrower.
•
Roll the front and rear auger belts off the engine
pulley. See Figure 16.
•
Unhook the idler spring from the hex bolt on the
auger housing. See Figure 17.
•
Back out the stop bolt until the support bracket
rests on the auger pulley.
NOTE:
Loosening the six nuts that connect the frame to
the auger housing may aid in belt removal.
Figure 16
•
Lift the auger belt from the auger pulley, and slip
belt between the support bracket and the auger
pulley. Repeat this step for the front auger belt.
•
Replace the auger drive belts by following
instructions in reverse order.
NOTE:
If you placed plastic film under the gas cap, be
certain to remove it before operating the snow thrower.
