Maintenance

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:
a. Remove the six hex nuts, bell washers, and carriage
bolts that secure the shave plate to the bottom of
the housing.
b. Remove the rear most hex nut, bell washer, flat
washer and carriage bolt securing the back end of
each skid shoe to the sides of the housing. Loosen
the four remaining hex nuts that secure the skid
shoes to the housing.
c. Slide the shave plate out of the off-set slot at the
bottom 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. Loosely install the six
carriage bolts, bell washers, and hex nuts fastening
the shave plate to the bottom of the housing.
e. Insert the carriage bolts through the rear of skid
shoes and the ends of the shave plate and the install
the flat washers, bell washers, and hex nuts removed
earlier.
f. Reposition the skid shoes and fully tighten the
fasteners securing the skid shoes to the housing.
Fully tighten the fasteners securing the shave plate.
The skid shoes are reversible for longer life. Remove the hex nuts,
flat washers, bell washers and carriage bolts 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 six shear
pins and bow-tie cotter pins. Refer to Figure 7-1. If an auger
is suddenly jammed by a foreign object or ice chunk, the
pin is designed to shear — minimizing potential damage to
the gear box or sprocket box.
2. If the augers will not turn, check the pins to see if they
have sheared. Two replacement shear pins (5, Fig. 3-2) and
bow-tie cotter pins (12, Fig. 3-2) have been provided with
the snow thrower. For future use, order part number 738-
04124A for replacement shear pins and 714-04040 for the
bow-tie cotter pins.

Lubrication
1. The auger gear box is lubricated with grease at the factory
and is neither externally serviceable, nor requires checking.
If disassembled for any reason, lubricate with 2 ounces (by
weight) of Shell Alvania grease, part number 737-0168.
Before reassembling, remove all old sealant and apply
Loctite Ultra Grey (759-3746) sealant, or equivalent, to the
housing halves.
2. The sprocket box assembly is also neither externally
serviceable, nor requires checking. If disassembled for any
reason, lubricate with 5.0 ounces (by weight) of Benalene
grease, part number 737-0300A. Before reassembling,
remove old sealant and apply Loctite Ultra Grey (759-3746)
sealant or equivalent.
3. The right angle gear box is not serviceable and should not
be disassembled.
4. Apply penetrating oil to the cables of the chute tilt handle
assembly at least once a season.
5. Apply a good grade of spray lubricant to the universal
joints of the chute crank, and to the pivot of the chute tilt
handle at least once a season.
6. Lubricate the chute crank spiral gear with a multi-purpose
automotive grease once a year.
7. Lubricate the telescoping square spindle of the drive shaft
(rear half) using 251H EP grease or an equivalent No. 2
multi-purpose lithium grease once a year.
8. Lubricate the bearings at each end of the auger shaft with
oil or spray lubricant at least once a season.
9. Although not necessary, it is advisable to remove the auger
shear pins at least once a season and spray penetrating oil
between the auger tubes and auger shaft.
