Servicing Augers

The augers are secured to the spiral shaft with two shear pins and cotter pins. See Figure 15 . If you hit a foreign object or ice jam, the snow thrower is designed so that the bolts will shear.

1.If the augers do not turn, check to see if the pins have sheared.

2.Replace the pins if needed. Two replacement shear pins and cotter pins have been provided with the snow thrower. Spray an oil lubricant into shaft before inserting new pins and securing with new cotter pins. See Figure 15.
