MAIIMTEIMAIMCE

Ariens Company recommends that you have ad justments made by your local Ariens 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 ob tainable. 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 Sno-Thro yourself, Ariens recommends that you call your dealer for the answers to any questions that might arise in perform

ing this work.

SHEAR BOLT REPLACEMENT - FIGURE 12

Occasionally an object may enter the collector 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 preventing 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. Lubricate rakeshaft according to in

structions in "LUBRICATION".

RUNNERS AND SCRAPER BLADE - FIGURES 2 & 12

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 blade is adjustable so it may be lowered to compensate for wear. See Figure 12 and page 12 il lustration. Loosen locknuts securing scraper blade and move it down to compensate for wear. Retighten locknuts. If the blade is allowed to wear down too far the blower housing may be damaged.

ATTACHMENT CLUTCH ADJUSTMENT - FIGURE 16

The Attachment Clutch is adjusted by connecting the chain to the spring just below the attachment clutch rod. Connect the spring to a chain link so the chain is snug but so the attachment idler (Figure f) drops away from the blower drive belt with the lever all the way up.

TRACTION CLUTCH ADJUSTMENT - FIGURE 3

A drive disc adjustment is provided to compensate for wear on the friction wheel. If slippage occurs when the traction clutch is engaged, perform the drive disc ad justment. This adjustment is possible without removing the bottom cover. "Lock in" the differential during this

procedure.

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. Runners are adjusted by loosening the two nuts securing each runner. See Figure 2. 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 run ners 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 snow 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.

FIGURE 3

Adjust as follows: Place Speed Selector in First. Tip machine forward on blower housing. Tighten the ad

justment nut while turning the wheels until the wheels

begin to drag. When wheels begin to drag, the clutch lever should be engaged and released to realign clutch linkage prior to adjustment. It may be necessary to repeat this procedure until proper adjustment is obtain ed. Turn nut back three turns. Wheels should then turn easily.

CHUTE CRANK ADJUSTMENT - FIGURE 4

In the event the chute crank fails to rotate smoothly loosen the nut securing the worm clevis to the bracket. This hole In the bracket is slotted to permit adjustment. Position the worm so it aligns with the teeth on Discharge Chute and there is a little clearance between worm and the gear teeth. Tighten the nut. Rotate the discharge chute through its full travel to see that it turns easlily. Readjust if required. Lubricate as describ ed in "LUBRICATION" section. Tension on chute crank

ment nuts on the end of the crank to put increased ten sion on the washers and wave washers.

Tires should be inflated to 1 2 to 20 PSI. If tire chains are used, a pressure of 20 PSI is recommended.

REMOVAL OF BLOWER HOUSING AND BELT REPLACEMENT

drive belt off the engine sheave between the sheave and belt finger. This can be easily done by pulling the recoil starter rope to rotate the engine sheave. With the belt disconnected, the blower housing may then be lifted from the frame.

REPLACEMENT OF THE BLOWER DRIVE BELT

CAUTION: SINCE REPLACING THE BELTS WILL IN VOLVE TURNING THE ENGINE OVER WITH THE STARTER, AND THE ENGINE MIGHT ACCIDENTALLY START RESULTING IN INJURY, THE SPARK PLUG WIRE MUST BE DISCONNECTED DURING THIS PRO CEDURE.

The Sno-Thro blower drive belt is located on the sheave of the blower housing. To replace this belt, hold the im peller brake away from the belt and slip the belt from the sheave. See Figure 5.

Replace the blower drive belt by slipping it into position on the sheave, positioning the brake shoe on the belt.

CAUTiON: SINCE REPLACING THE BELTS WILL IN VOLVE TURNING THE ENGINE OVER WITH THE STARTER, AND THE ENGINE MIGHT ACCIDENTALLY START RESULTING IN INJURY, THE SPARK PLUG WIRE MUST BE DISCONNECTED DURING THIS PRO CEDURE.

The traction drive belt and the blower drive belt are

both accessible by removing the blower housing as follows:

1. See Figure 21 ("ASSEMBLY & PRE-SERVICE" section). Remove hairpin securing the deflector control cable to the deflector. Loosen jam nuts securing deflector control cable to bracket on chute. Then free the cable from the Sno-Thro blower housing.

2. Remove the hair pin cotter in the chute crank assembly. Separate the chute crank. See Figure 4.

3. Remove the two screws securing the belt guard to the tractor. Remove the belt guard.

NOTE: TIPPING THE TRACTOR BACK ON THE HANDLEBARS WHEN SEPARATING THE UNITS MAY RESULT IN BENDING THE BOTTOM COVER. TO AVOID THIS SITUATION, EITHER TIP THE UNIT UP ON THE BLOWER HOUSING AND REMOVE THE BOTTOM COVER BEFORE SEPARATING THE UNITS; OR SUP

PORT THE HANDLEBARS SO THE TRACTOR DOES NOT TIP ALL THE WAY OVER; THEN LIFT OFF THE

BLOWER HOUSINiS.

MAINTENANCE

The traction drive belt is held in place on the sheaves by an idler pulley. To free the belt, the idler can be pulled from the belt and the belt removed from the sheave.

Activate traction clutch to gain clearance. It may be necessary to pull back attachment idler arm clevis pin

for additional clearance. To replace the belts, position on the engine sheave

first, then on the drive sheave. Position the idler carefully on the belt.

With the belt in position and the idler in place, check the belt alignment. The engine sheave and the traction sheave must align with one another WITH THE TRAC TION CLUTCH ENGAGED. If the sheaves are not

properly aligned, loosen the setscrews on the engine sheave and align the sheaves. Re-tighten the setscrews. Recheck the belt alignment WITH THE TRACTION CLUTCH ENGAGED. Replace spark plug wire.

A NOTE ABOUT ARIENS BELTS ARIENS BELTS are individually engineered to the

highest standards of material quality, design, and con

struction including special cording locations for strength and stability. This assures that the belts will deliver maximum performance and durability for each
