SECTION IV. MAINTENANCE
Section IV describes maintenance procedures de-
signed 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.
1.
Replace the shave plate as follows:
a.
Remove the seven carriage bolts and hex
flange lock nuts that secure the shave plate to
the bottom of the housing.
b.
Remove the rear most carriage bolt, bell
washer and 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.
c.
Slide the shave plate out of the off-set slot of
the housing, and from between the skid shoes
and side panels of the housing.
d.
With the mounting holes toward the back, slide
the new shave plate into position and secure
with the fasteners removed previously.
2.
The skid shoes are reversible for longer life. Re-
move the carriage bolts, bell washers and hex in-
sert 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
1.
The augers are secured to the auger shaft with two
shear bolts and hex insert lock nuts. Refer to Fig-
ure 14. If the auger is suddenly jammed by a for-
eign object or ice chunk, the bolts are designed to
shear — minimizing potential damage to the gear
boxes.
2.
If the augers will not turn, check the bolts to see if
they 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.
