Thrower

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 6-9.

•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.

Drive Belt Replacement

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. See Figure 6-9.

NEVER replace the auger shear pins with standard hex pins. Any damage to the auger gearbox or other components as a result of failing to do so will NOT be covered by your snow thrower’s warranty.
