SHEAR BOLTS
(Figure 28)
IMPORTANT: Use only Ariens OEM shear
bolts for replacement. Use of any other type
of shear bolt may result in severe damage to
unit. See SERVICE PARTS on page 40.
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 case.
For Replacement:
1. Align shear bolt holes in auger with
shear
bolt holes in the shaft.
2. Drive shear bolt through hole (if shea
r
bolt
was broken this will drive re
maining
p
art from shaft).
3. Secure shear bolt with nut.
NOTICE: DO NOT overtighten the shear bolt.
Tighten shear bolt to 5.8 – 12.2 lbf-ft
(7.9 – 16.5 N•m).
