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. See SERVICE PARTS on page 37.

Occasionally a foreign object may enter the auger/impeller housing and jam the auger, breaking shear bolts (Figure 24) which secure the auger to the shaft. This allows auger to turn freely on the shaft which may help prevent damage to gear drive.
