Augers
Grease
The augers are secured to the spiral shaft with 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. See Figure 21.
If the augers will not turn, check to see if the pins have
sheared. One set of replacement shear pins has been
provided with the snow thrower. When replacing pins,
spray an oil lubricant into shaft before inserting  new
pins.
