Augers
The augers are secured to the spiral shaft with four
shear pins and cotter pins. If you hit a foreign object or
ice jam, the snow thrower is designed so that the pins
may shear.
If the augers do not turn, check if the pins have
sheared. Replace, if needed, with proper shear pins.
Refer to the Replacement Parts section for correct
part number.
CAUTION: NEVER replace the auger shear
pins with standard pins or fasteners. Any
damage to the auger gearbox or other
components, as a result of doing so, will
NOT be covered by your snow thrower's
warranty.
Replacing Shear Pins
CAUTION: NEVER replace the auger
shear pins with anything other than OEM
Parts No. 738-04124A replacement shear
pins and 714-04040 bow-tie cotter pins.
Any damage to the auger gearbox or
other components as a result of failing to
do so will NOT be covered by your snow
thrower attachment's warranty.
WARNING! Always turn off the snow
thrower's engine, as instructed in the
engine owner's manual and remove the
key prior to replacing shear pins.
1. Replace the shear pins as shown in Figure 5-5.
