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).
HANDLEBAR HEIGHT
(Figure 23 and 24)
To raise or lower the handlebar:
1. Remove hair pin holding chute rod to
control assembly.
2. Place unit in service position (see
Service Position
on page 20).
3. Remove bottom cover.
4. Remove top mounting bolts from the
handlebars and adjust the handlebar up
or down as needed until the handlebar
mounting holes align with holes in unit
frame.
5. Secure handlebar to frame with
hardware removed in step 4 using the
different hardware locations shown in
Figure 23.
NOTE:
Insert the hair pin with the loop end on
the left side of the chute rod so the control
lever will cover its full range of travel.
6. Align correct chute rod holes in chute
control assembly as shown in Figure 24,
and then secure chute rod in position
with hair pin remove in step 1.
CAUTION:
AVOID INJURY. Adjust
the attachment clutch, speed
selector and traction clutch after
changing the handlebar height. See
Attachment Clutch/Brake
Adjustment
on page 26 and
Speed
Selector Adjustment
on page 25.
