SECTION 10 - AUGER/IMPELLER

10.1 AUGER/IMPELLER REMOVAL

Place unit in the belt service position.

1. Remove bolt holding auger driven pulley to shaft and remove pulley.

2. Remove three nuts holding bushing flange to housing and remove flange on each side.

3. Grasp auger assembly and pull gear case and auger/impeller assembly free of housing.

4. Remove shear bolts and remove auger from shaft.

5. Check all parts for wear or replacement.

6. Assemble using reverse procedure.

10.2 SHEAR BOLTS

WARNING: Stop engine, remove key, wait for

moving parts to stop and remove wire from spark plug before leaving operator’s position and attempting to maintain or inspect auger.

IMPORTANT: Use only Ariens shear bolts for replacement. Use of any other type of shear bolt may result in severe damage to unit.

Occasionally an object may enter auger/impeller housing and jam auger, breaking shear bolts which secures auger to shaft. This allows auger to turn freely on shaft preventing damage to gear drive.

To replace shear bolt:

1. Slide auger outward against roll pin and align hole in shaft with hole in auger (

Figure 23). The holes in

shaft for roll pins and shear bolts will line up.

2. Drive the new shear bolt through hole (if shear bolt was broken this will drive remaining part from shaft).

3. Secure with nut.

10.4 RUNNERS

CAUTION: Adjust auger/impeller housing

height to clear gravel or crushed rock surfaces.

Runners should be adjusted as co nditio ns requi re (

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. O n 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 adjusting 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 (

3. If flange bushings need replacement, first remove seals from outside of gearcase halves with a screwdrive r. Flange bushings can t hen be pr essed 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.

Figure 26).

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.
