Slide the shave plate out of the off-set slot of the c.
housing, and from between the skid shoes and side
panels of the housing.
With the mounting holes toward the back, slide the d.
new shave plate into position and secure with the
fasteners removed previously.
The skid shoes are reversible for longer life. Remove the carriage
bolts, bell washers and hex insert lock nuts fastening the skid
shoes to the housing. Turn the shoes over and/or reverse sides to
ensure even wear and extend their service life.
Augers
The augers are secured to the auger shaft with two shear 1.
bolts and hex insert lock nuts. Refer to Figure 7-1. If the
auger is suddenly jammed by a foreign object or ice chunk,
the bolts are designed to shear — minimizing potential
damage to the gear boxes.
If the augers will not turn, check the bolts to see if they 2.
have sheared. Two replacement shear bolts (7) and hex
insert lock nuts (8) have been provided with the snow
thrower. For future use, order part number 710-0891 for
replacement shear bolts and 712-0429 for the lock nuts.
During Seasonal Usage
This section describes maintenance procedures designed to keep
your snow thrower in good operating condition.
Shave Plate And Skid Shoes
The shave plate and skid shoes on the bottom of the snow
thrower housing are subject to wear. They should be periodically
checked for wear and replaced when necessary. Failure to do so
will result in damage to the housing. Refer to Figure 7-1.
Replace the shave plate as follows:
Remove the all of the carriage bolts and hex flange a.
lock nuts that secure the shave plate to the bottom
of the housing.
Remove the rear most carriage bolt, bell washer and b.
hex insert lock nut securing the back end of each
skid shoe to the sides of the housing.
NOTE: If necessary to ease sliding the shave plate out of
position on the housing, loosen the four remaining hex
insert lock nuts which secure the skid shoes to the housing.
