4. Replace attachment drive belt (See Replace Attachment Drive Belt).

4.11 SHEAR BOLTS
IMPORTANT: Use only Ariens shear bolts for replacement. Use of any other type of shear bolt may result in severe damage to unit.
Occasionally a foreign object may enter the auger/ impeller housing and jam the auger, breaking shear bolts (Figure 8) which secure the auger to the shaft.
This allows auger to turn freely on the shaft preventing damage to gear drive.

For Replacement:

1. Align shear bolt holes in auger with shear bolt holes in the shaft.
2. Drive shear bolt through hole (if shear bolt was broken this will drive remaining part from shaft).
3. Secure shear bolt with nut.

4.12 TIRE PRESSURE
Keeps tires inflated to the pressure listed on the tire sidewall.

SECTION 5 – SERVICE AND ADJUSTMENTS

5.1 DEFLECTOR REMOTE
Deflector must stay in selected position while throwing snow.
If deflector does not stay in set position:

1. Tighten nut beneath the control panel to increase friction on pressure flange (Figure 9).

If deflector does not follow full range of travel:

1. Push deflector remote all the way forward.
2. Loosen adjusting nuts on cable support bracket.
3. To adjust the deflector lower, slide cable down. Tighten bottom nut.
4. To adjust deflector higher, slide cable up. Tighten top nut.
5. Check travel and repeat adjustment as necessary.

5.2 DISCHARGE CHUTE
If chute does not stay in position while operating, tighten nut on carriage bolt at pivot point to increase tension on spring (Figure 10).
Smooth and easy rotation of properly lubricated chute with crank is obtained by adjusting pinion and chute gear teeth so they mesh together.

5.3 RUNNERS
Runners should be adjusted (Figure 11) as conditions require.

1. Position unit on a hard, flat, smooth level surface.
2. Adjust runners by inserting a spacer of desired thickness under center of scraper blade, loosen runner hardware, slide runners to flat surface. Allow 1/8 in. (3 mm) between scraper blade and hard smooth surfaces. Allow 1-1/4 in. (30 mm) between scraper blade and uneven or gravel surfaces. Retighten hardware.

NOTE: Keep housing level by adjusting runners equally.

5.4 ATTACHMENT CLUTCH/BRAKE ADJUSTMENT

WARNING: IMPROPER ADJUSTMENT could result in unexpected movement of auger and impeller causing death or serious injury. Auger / impeller must stop within 3 seconds when attachment clutch/impeller brake lever is released.

10.3 DISCHARGE CHUTE

WARNING: DO NOT put hands or feet near or under rotating parts. Keep clear of discharge opening at all times.
WARNING: NEVER direct discharge of material toward bystanders nor allow anyone in front of equipment while unit is in operation.
Be familiar with area of operation.

To remove discharge chute unbolt the chute positioning assembly from the discharge chute. Tip discharge chute forward and lift.
NOTE: Chute must rotate freely. To adjust the gears tighten or loosen the lower nut (Figure 24). This will adjust the spring tension on the gears.

10.4 RUNNERS
CAUTION: Adjust auger/impeller housing height to clear gravel or crushed rock surfaces.
Runners should be adjusted as conditions require (Figure 25). Raising or lowering runners controls distance scraper blade is held above surface being cleared.
When operating machine on gravel surface, lower runners so the housing will not pick up gravel. On concrete, blacktopped or packed down snow surfaces, raise runners so that scraper blade scrapes clean.
Position unit on a flat level surface. Adjust runners by inserting a spacer of desired thickness under center of scraper blade, loosen hardware, slide runners to flat surface and retighten hardware.
NOTE: Above method keeps housing level by adjust ing runners equally. Uneven runners make machine difficult to steer and results in uneven clearing.

SECTION 11 – GEAR CASE

11.1 ALUMINUM GEAR CASE

1. Remove auger/impeller and gear case from housing referring to Auger/Impeller Section.
2. Remove eight bolts that hold right and left gear case halves together (Figure 26).
3. If flange bushings need replacement, first remove seals from outside of gearcase halves with a screwdriver. Flange bushings can then be pressed out from outside in with a bearing driver. Bushings are very lightly pressed in.
4. When replacing bushings make sure the flat on the flange of bushing fits in the inside notch of the case.
5. There are two special thrust washers, one on either side of worm gear. If burred or worn, they should be replaced.
6. Holding the worm gear on rake shaft is a wood ruff key.
7. Remove bronze bushing from front of worm shaft by sliding it off. Replace if necessary. Notice that a flat on the bushing flange positions the bearing inside the gearcase.
8. Behind rear bronze bushing is a seal which fits into a groove in gearcase. It should be replaced at time of repair.
9. Rear bushing is a larger diameter than one in front, but are identical in design. Replace if necessary.
10. If replacement of thrust collar is necessary, drive out groove pin towards direction of least resistance.
11. Inspect worm shaft for burrs or black coloration. If either show up, replace shaft.
12. Prior to re-assembly, apply anarobic sealant to a clean surface. Allow to cure for 24 hours. Reassemble. Make sure the flats on the bushings are in their proper place.

This case requires Ariens L-2 P/N 00008000 and should be half full.
After assembly is complete you should be able to turn input shaft freely.
Auger/impeller gearcase is lubricated with Ariens L-2 (P/N 00008000). Check lubrication by removing filler plug. Lubrication should be even with hole with unit sitting level. It may be necessary to insert a wire into the hole to check level. Unit will not be damaged by over-lubricating.
