SHEAR BOLTS
(Figure 22)
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 33.
Occasionally a foreign object may enter the
auger/impeller housing and jam the auger,
breaking shear bolts which secure the auger
to the shaft. This allows auger to turn freely
on the shaft which may help prevent damage
to gear drive.

For Replacement:
1. Align shear bolt holes in auger with
shear bolt holes in the shaft.
2. Drive shear bolt through hole (if shear
bolt was broken this will drive remaining
part from shaft).
3. Secure shear bolt with nut.
NOTE: DO NOT overtighten the shear bolt.
Tighten shear bolt to 5.8 – 12.2 lbf-ft (7.9 –
16.5 N•m).
