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 16) which secure the auger to the
shaft. This allows auger to turn freely on the shaft
preventing damage to gear drive.
For Replacement:
1. Slide auger outward against roll pin and align
hole in shaft with hole in auger (holes in shaft for
roll pins and Shear Bolts line up).
2. Drive shear bolt through hole (if shear bolt was
broken this will drive remaining part from shaft).
WARNING: AUGER / IMPELLER MUST
STOP within 5 seconds when Attachment
Clutch Lever is released or unit damage or
serious injury may result.
