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
which secure the auger to the shaft (Figure 9). 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).
2. Drive Shear Bolt through hole (if Shear Bolt was
broken this will drive remaining part from shaft).
3. Secure Shear Bolt with nut.

1. To replace friction wheel, tip unit up onto housing on
a flat level surface.
2. Remove bottom cover by removing four cap screws.
3. Place Speed Selector in first (1) position, depress
Traction Clutch Lever to hold friction wheel and hub
in position and remove cap screws . Release traction
clutch lever, shift to third (3) position, and remove
friction wheel (Figure 10).
4. Secure new friction wheel on hub with five cap
screws and torque cap screws to 8-10 ft. lbs.
(10,6-13,3 Nm)
5. Replace bottom cover.
6. Adjust Traction Drive Clutch (see Adjustments).

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 ensure adequate lubricant level:
1. Remove filler plug. Lubricant must be at least up to
bottom of lubricant filler hole with unit resting on a
level-surface.
2. Add lubricant, if required, allow oil to drain to level of
plug and replace plug (Figure 11).
3. Use only Ariens special gear lubricant L-2 (Part
Number 00008000).
