AUGERS
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. See Figure 16. If you
hit a foreign object or ice jam, the snow thrower is
designed so that the shear bolts will shear.
If the augers will not turn, check to see if the hex
bolts have sheared. Two replacement
shear bolts
and hex lock nuts have been provided with the snow
thrower. When replacing bolts, spray an oil lubricant
into shaft before inserting new bolts.
