ADJUSTMENTS/ MAINTENANCE
Ariens Company recommends that you have adjustments made
by your local Aliens dealer. He has the tools and know-how to
properly perform these maintenance adjustments which may be
required to keep the Sno-Thro operating at peak efficiency. The
Sno-Thro is equipped with the finest quality engine obtainable.
However, should servicing be required, it can be obtained from
an Ariens dealer or an authorized engine manufacturer’s service
station. Should you decide to make adjustments on your SnoThro yourself, Ariens recommends that you call your dealer for
the answers to any questions that might arise in performing this
work.
SHEAR BOLT REPLACEMENT - FIGURE 2
Occasionally an object may enter the blower and jam the rakes.
When this occurs, the shear bolts securing the rakes to the shaft
will break and allow the rake to turn freely on the shaft preven
ting damage to the gear drive. When this happens, turn off the
engine, remove wire from spark plug, remove the broken shear
bolt and replace with a new ARIENS shear bolt. Use of any other
type of shear bolt may result in severe damage to the machine.
USE ONLY ARIENS SHEAR BOLTS FOR REPLACEMENT. Each
time a shear bolt is replaced (and once each year) the rake
should be rotated on the shaft and the shaft lubricated. Refer to
“LUBRICATION” section.
RUNNERS AND SCRAPER BLADE — FIGURES 2 & 3
Lever touching the hub. If the Activator Lever touches the hub,
the attachment idler (Figure 9) must be adjusted in the idler arm.
Loosen the cap screw on the idler and move idler IN TOWARD the
belt. Readjust the spring in the chain for proper action.
Make sure that all linkage works freely so that blower idler snaps
quickly and freely to disengaged position when Attachment
Clutch Lever is released. Make sure that the blower impeller
(fan) comes to a quick (5 seconds) stop when Attachment Clutch
Lever is released.
NOTE: SEE, ALSO. “ASSEMBLY AND PRE-SERVICE” SECTION
OF THIS MANUAL.
The runners on each side of the blower housing, and the scraper
blade, along the bottom of the housing, are all adjustable to suit
conditions. Raising or lowering the runners controls the distance
the scraper blade is held above the surface being cleared. Run
ners are adjusted by loosening the two nuts securing each run
ner. Move the runner to the desired position and retighten the
nuts. Be sure to adjust both runners to the same height to keep
blower housing level. Uneven runners make the machine difficult
to steer and will result in an uneven clearing job.
Adjustment of the runners is critical to good cleaning. If the
machine is to be used on a gravel surface lower the runners so
the blower will not pick up gravel. After the remaining sno.w is
packed down, the runners may be raised for close scraping. On
smooth concrete or blacktopped surfaces, the runners may be
raised so the scraper blade rests on the surface and scrapes
clean.
The runners may be removed from the blower housing and re
installed in upside-down position to reduce contact area and thus
reduce tendency to ride up when clearing hard-packed snow.
The scraper is adjustable so it may be lowered to compensate for
wear. See Page 12 illustration. Loosen locknuts securing
scraper blade to adjust. Retighten locknuts. If the blade Is al
lowed to wear down too far the blower housing may be damaged.
ATTACHMENT CLUTCH ADJUSTMENT — FIGURES 4 &
5
The Attachment Clutch is adjusted by connecting the spring on
the clutch rod into the proper link on the Clutch Lever. Properly
adjusted, the spring should be slightly extended with the clutch
lever down. This should occur without the Attachment Activator

ADJUSTMENTS/ MAINTENANCE
CHUTE CRANK ADJUSTMENT ~ FIGURE 6
In the event the chute crank fails to rotate smoothly, loosen the
nut securing the worm clevis to the bracket. This hoie in the
bracket is slotted to permit adjustment. Position the worm so
there is a little clearance between worm and the gear teeth on the
blower. Tighten the nut. Rotate the discharge chute through its
full travel to see that it turns easily. Readjust if required.
Lubricate as described in “LUBRICATION” section for smooth
operation.
TRACTION CLUTCH ADJUSTMENT - FIG. 5, 7 & 13B
The only adjustment for the drive disc is made by adjusting the
length of the traction clutch rod. Loosen setscrew in the rod

FIGURE 10
SNO-THRO UNIT - FIGURES 11 & 12
The blower gear case is lubricated with Ariens Liquid Grease
(Part No. 000070). This grease will not flow at lower
temperatures, it is therefore difficult to check the lubricant level.
Best method for checking is to place the unit in a warm location
overnight. This allows the grease to flow to level. Check the
lubrication by removing the filler plug on the side of the gear
case just above the left auger shaft. Lubrication should be even
with the hole with the machine sitting level, it may be necessary
to insert a wire into the hole to check level. The unit will not be
damaged by over lubricating.
NOTE: OIL CAN (PUMP-TYPE) MAY BE USED TO LUBRICATE
WITH ARIENS LIQUID GREASE.
Some models are equipped with zerk fittings on the rake shaft.
See Figure 11B. For those models that do not have zerk fittings,

tion). If this is not achieved, check blower idler adjust
ment according to paragraph "d" (attachment drive
belt tension may be too tight) and belt finger adjust
ment (paragraph "e"). Reinstall belt cover.
CAUTION: PROPER FUNCTION OF ATTACHMENT CLUTCH CAN
BE ASSURED ONLY WHEN THE PREVIOUS STEPS IN “ATTACH
MENT CLUTCH” SECTION HAVE BEEN PERFORMED.
CHUTE CONTROL CRANK — FIGURE 16
The chute control crank is shipped fully assembled and In place
in the bracket. Install as follows: Bolt the crank clamp in place
on the left handlebar. See Figure 16.
Position the worm clevis on the bracket on the blower housing.
Place external tooth lockwasher between worm clevis and
bracket. Adjust in slot so that there is a little clearance between
worm and gear teeth on blower collar.
Secure the worm clevis with the carriage bolt (already in place on
the clevis). Use a lockwasher (63023) and a 5/16-18 nut
(65015) under the bracket. See Figure 16.
Rotate the discharge chute through its full travel to see that it
turns easily. Readjust the position of the worm clevis, if re
quired. Oil discharge chute, see Figure 17B.
DEFLECTOR - FIGURE 17
The deflector is shipped in place on the discharge chute but
must be raised into operating position. Remove the locking hard
ware from the discharge chute. Raise the deflector up into posi
tion. Re-install the hardware as shown In Figure 17A. Adjust the
nut to apply sufficient tension so the deflector can be easily
moved by hand but will still hold position when blowing snow.
BLOWER GEAR CASE
The blower gear case is factory lubricated and should require no
lubrication by the dealer.
The blower gear case Is lubricated with Ariens Liquid Grease
(Part No. 000070). This grease will not flow at lower
temperatures. It is therefore difficult to check the lubricant level.
Best method for checking is to place the unit in a warm location
overnight. This aliows the grease to flow to level. Check the
lubrication by removing the filler plug on the side of the gear
case just above the left auger shaft. Lubrication shouid be even
with the hoie with the machine sitting level. It may be necessary
to Insert a wire into the hoie to check levei. The unit will not be
damaged by over lubricating.
