The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. Refer to Figure 28. If
you hit a foreign object or ice jam, the snow thrower
is designed so that the hex bolts will shear.

have sheared. Two replacement shear bolts and
hex lock nuts have been provided with the snow
thrower. For future use, order part number 710-
