OF OTHER TYPES OF BOLTS MAY RESULT IN SEVERE
DAMAGE TO MACHINE. STOP THE ENGINE BEFORE
ATTEMPTING TO REMOVE OBSTRUCTIONS OR RE­
PLACE SHEAR BOLTS.
NOTE: Each time a shear bolt is replaced, the
rakes must be greased and turned on the shaft by
hand several times to insure they do not bind.
7. SNO-THRO OPERATING HINTS
a. When operating the Sno-Thro in wet snow,
occasionally a sufficient amount of snow may stick
inside the chute causing partial clogging. To prevent
this, it is suggested that the inside of the chute be
coated with a light layer of "paste" or "spray" wax.
b. After blowing snow, let the engine run for
approximately 5 minutes to dry off the unit to prevent
freezing of engine control parts.
c. Move throttle lever to park position after
engine is stopped to lessen the possibility of
damaging the control if freezing occurs.
d. When placing unit back in the garage, shift the
unit to neutral and disengage the engine clutch and
sno-thro clutch.
8. BELT REPLACEMENT
a. On models produced before December 1965 it
is necessary to remove the belt guard by unsnapping
the latches on each side and lifting off the guard. The
belt guard on models produced after December 1965
can be removed by removing the cap screws lifting off
the guard.
b. Turn Sno-chute so that slot in flange lines up
with tooth on the control sprocket.
c. 1969-70 model 10,000 series remove clevis pin
assembly and disconnect worm gear from teeth.
d. Remove two cap screws and separate blower
housing and tractor unit by tipping back on the handle
bars.
e. With Idler Handle in DOWN position and the
Throttle Control in the OFF position, the belt can be
removed from top pulley slowly on the starter rope as
finger pressure against the belt rolls it out of the
pulley groove.
f. New belt can be installed on pulleys easily but
it may require readjustment of the idler. With clutch
engaged the idler must be adjusted so that the clutch
spring is approximately 4% inches.
9. BLOWER HOUSING DISASSEMBLY
a. After having separated the blower housing
and tractor unit, drive out two roll pins to free the
clutch fork. Use 3/16" Punch and Hammer.
b. The fork can be turned as the jaw coupling,
spring and washer are pulled from the splined shaft.
c. The fork shaft can now be removed if any of its
associated parts need replacement.
d. Remove two cap screws, washers and lock
washers from each end of the front gear shaft. Use
Ratchet with 3/4" socket.
e. Remove the three locknuts on each bearing
support and pull the bearing supports from the shaft
on each side. If a bushing in the bearing support re­
quires replacement, it can be driven out with an
Ariens No. 97 bearing driver. Use Ratchet with 7/16"
socket.
f. The complete rotor and gear case assembly
can now be removed from the blower housing. The
pinion shaft will pull out of the rear bearing on the fan
end.
g. Drive out the roll pins on each end of front
gear shaft with 3/16" punch. The models built before
1965 did not have the roll pins, but the front gear shaft
is completely interchangeable although the 2 roll pin
holes may not be used, rakes produced in 1965 are to
be used without roll pins unless 1/8" is machined off
outside ends.
h. Remove 2 shear bolts and nuts. Use 1/2" Open
End Wrench and Ratchet with 1/2" socket.
i. Slide off rakes.
10. DISASSEMBLY & ASSEMBLY OF GEAR CASE
a. Remove pipe plug and drain oil. Use 7/16"
Open End Wrench.
b. Remove cap screws holding flange and
remove flange and gasket. Use 7/16" Ratchet
Wrench.
c. Insert punch through oil filler hole to drive roll
pin out of helicon gear just far enough to clear shaft.
Use 5/16" Punch and Hammer.
d. Pull out front gear shaft.
e. After shaft is removed, it is possible to remove
helicon gear by tipping to clear pinion shaft.
f. Unscrew adjustment plug. Use 2 screwdrivers.
g. Insert punch through the oil filler hole and
drive pinion shaft assembly out of gear case. Use 3/8"
Punch and Hammer.
h. Remove bearing cup and snap ring from inner
portion of gear case only if necessary.
i. To Reassemble.
j. Pin Helicon gear on front gear shaft.
k. Insert front gear shaft assembly into gear
case.
l . Put in helicon shaft assembly and drive in
bearing cup. Use # 131 Bearing Driver.
m. Use No. 90 Bearing Adjustment Wrench. And
in reassembling, first install new seal against
shoulder in adjustment plug. On adjustment nuts
used prior to this year, insert the seal so that top of
the seal is flush with bottom of the spanner slot or
about 1 /32 of on inch below the bottom of the nut. We
recommended replacing with the new style nut. Use
#130 Seal Driver.
n. Seal the adjusting nut in position by putting a
small bead of gasoila sealer in the GEAR CASE. The
nut will drag the sealer around threads. Retighten
adjustment nut until a slight drag is felt when turning
the pinion shaft. DO NOT BACK OFF AS PREVIOUSLY
ADVISED. Use No. 90 Bearing Adjustment Wrench.
11. FRICTION WHEEL REMOVAL (1972 & AFTER)
a. Remove (4) tap tites on bottom cover.
b. Remove cover.
c. Shift to second speed.
Remove the cotter pin
