Snowblower Auger Shear Bolts- Yarmand Tech Video Blog

You may find that during a snowstorm the snowblower auger (s) stops turning all of a sudden.

This may be due to broken auger shear bolts. Luckily it's a simple and inexpensive fix.The purpose of auger pins or bolts are to act as a safety mechanism to prevent any severe damage due to overload. So, if you were to go thru heavy snow or catch something in the auger, the bolts 'shear' to prevent any damage to the auger differential gears.

When you break a shear pin, make sure to replace it with the proper bolts or pin made for your machine. Don't use any ordinary bolt or nail because they may not break under heavy load and can cause major damage. It's always a good idea to keep couple of spares in case you need them .
