Place unit in the Belt Service Position. 1. Remove three nuts holding pulley to hub and remove pulley and key. 2. Loosen set screw in hub and remove hub. 3. Remove three nuts holding bearing flange to housing and remove bearing flange (Figure 19). 4. Remove two cap screws and lock washers on each side of blower housing holding rake shaft in position and remove bushing. 5. Remove three lock nuts attaching bearing support to housing and remove bearing support. 6. Grasp auger assembly and pull gear case and auger/impeller assembly free of housing. 7. Drive roll pin out of shaft ends, remove shear bolts and remove auger from shaft. 8. Check all parts for wear or replacement. 9. Assemble using reverse procedure. 9.2 SCRAPER BLADE IMPORTANT: If blade wears too far auger/impeller housing may be damaged. Scraper blade is adjustable to compensate for wear. To adjust scraper blade: 1. Tip unit back onto handlebar and support the housing. 3 4 2 1 5 6 Figure 19 3. With runners adjusted to their full up position, reposition scraper blade down, flush with runners. 4. Tighten lock nuts. 9.3 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 19) (holes in shaft for roll pins and shear bolts 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. 1. Blower Housing 2. Scraper Blade 3. Rake 4. Shear Bolt 5.

Secure discharge chute with mounting clips and hardware. NOTE: Chute must rotate freely. To adjust the gears tighten or loosen the lower nut (Figure 20). This will adjust the spring tension on the gears. 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. 1. Chute Crank 2. Gear Cover 3.

Route cable through retainer mounted on engine and chute bracket. Replace jam nut and secure cable threaded connector (from left side) to deflector bracket with cotter pin. Position deflector in its lowest position with cable control pushed full in and tighten jam nuts on chute bracket. NOTE: Check deflector movement to highest position. Adjust jam nuts and/or threaded connector if necessary to obtain full travel. Slide handle end of deflector control cable through hole in upper handlebar panel and secure with washer and jam nut. Secure T-handle on end of deflector control cable. 9.6 RUNNERS Runners should be adjusted as conditions require (Figure 21). Raising or lowering runners controls distance scraper blade is held above surface being cleared. When operating machine on gravel surface, lower runners so that housing will not pick up gravel. On concrete, blacktopped or packed down snow surfaces, raise runners so that scraper blade scrapes clean. To reduce tendency of housing to ride up over heavy wet or hard-packed snow, remove runners and re-install with the narrow edge down. 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. CAUTION: Adjust auger/impeller housing height to clear gravel or crushed rock surfaces. 1. Deflector Cable 2. Runner 3. Discharge Chute 4.
