9.1 AUGER/IMPELLER REPAIR
1. Place machine on a flat, level surface.
NOTE: Placing blocking under the runners on the
blower housing may make auger removal easier.
2. Remove bolt holding auger drive pulley to shaft
and remove pulley.
3. Remove three tapping screws holding shaft
bushing to blower housing and remove flange on
each side.
4. Grasp auger assembly and pull gear case and
auger/impeller assembly free of housing.
5. Remove shear bolts and remove auger from shaft.
6. Check all parts for wear or replacement.
7. Assemble, using reverse procedure.
9.2 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 an object may enter auger/impeller
housing and jam auger, breaking shear bolts which
secures auger to shaft. This prevents damage to gear
drive by allowing auger to turn freely on shaft.
To replace shear bolt:
1. Slide auger outward and align hole in shaft with
hole in auger (
Figure 24). 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.
