Augers
• 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. Refer to Figure 9.
• 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.

To remove and replace your snow thrower’s auger belt,
proceed as follows:
1. Remove the plastic belt cover on the front of the
engine by removing the two self-tapping screws.
