Replacing Shear Pins
Tire Chain Kit
The augers are secured to the spiral shaft with two shear pins
and cotter pins. If the auger should strike a foreign object or ice
jam, the snow thrower is designed so that the pins may shear. If
the augers will not turn, check to see if the pins have sheared.
See Fig. 5-1.
