IMPORTANT; Use only Ariens Shear Bolts for
replacement. Use of any other type of shear bolt may
result in severe damage to unit.
Occasionally a foreign object may enter the auger/
impeller housing and jam the auger, breaking Shear
Bolts (Figure 8) which secure the auger to the shaft. This
allows auger to turn freely on the shaft preventing
damage to gear drive.
For Replacement:
1. Slide auger outward against roll pin 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).
Secure Shear Bolt with nut.

IMPORTANT: Too much lubricant may cause excessive
leakage. Too little lubricant will cause gear and/or
bearing damage. Proper oil level must be maintained for
operation.
Gear cases are filled to the correct level at the factory.
Unless there is evidence of leakage, no additional
lubricant should be required. Check for evidence of
leakage every 25 hours of operation.
To insure adequate lube level:
1. Remove filler plug. Lubricant must be at least up to
bottom of lube filler hole with unit resting on a level-
surface.
2. Add lubricant (Figure 10), if required. Allow oil to
drain to level of plug and replace plug.
3. Use only Ariens special gear lube L-2 (Part Number
00008000).
