13.2 SHEAR BOLT REPLACEMENT

WARNING: Stop engine, lower attachment,
remove key, and wait for moving parts to stop
before leaving operators position and
attempting to maintain or inspect auger.
Occasionally an object may enter auger/impeller
housing and jam auger, breaking shear bolts which
secure auger to shaft. This allows auger to turn freely
on shaft preventing damage to gear drive.
IMPORTANT: Use only Ariens Shear Bolts for
replacement. Use of any other type of shear bolt may
result in sever damage to unit.
To replace shear bolt, slide auger outward against
rollpin and align hole in shaft with hole in auger (holes
in shaft for roll pins and shear bolts line up). Drive
shear bolt through hole; (if shear bolt was broken this
will drive remaining part from shaft and secure with
nut).
