Removing a Snow Thrower Auger

A snow thrower is a tool used to remove snow. It has the two shear pins which break the ice into tiny pieces and direct them to an impeller. The impeller uses a discharge trough to move the snow away. If any hard object comes through the pins, the pins shear off and the auger stops spinning. Any damage to the auger makes the task of removing the snow from the driveway difficult and affects the ability of the snow thrower. Follow the simple steps below to remove the auger so you can replace it to get the snow thrower working.

Tools and Materials

  • Screwdriver
  • Wood piece
  • Cloth
  • Wrench

Step 1: Turning Off the Snow Thrower

Place the snow thrower on a hard surface. Turn the throttle to the Stop position, and wait for the parts to halt. Unplug the spark plug wire for safety.

Step 2: Cleaning the Auger

Use a cloth to remove the ice or snow that is accumulated on the auger. This allows you to inspect the auger properly.

Step 3: Removing the Belt 

Remove the belt cover at the back of the snow chute. Detach the 3 screws that secure the cover. Push a piece of wood into the auger to stop it from spinning. Remove the bolts at the corner and also from the end of the belt-keeper bracket. Remove the end of the belt-keeper bracket from the pulley. Pull the hairpin clip from the ferrule rod that is present in front of the pulley. Now, remove the belt.

Step 6: Removing the Pulley

Remove the bolt that secures the drive pulley using a wrench. Remove the washer, and slide the pulley off the snow thrower.

Step 7: Removing the Auger

Use the wrench to remove the screws that connect the auger bearings to both ends of the auger housing. Remove the auger assembly from the auger housing. Remove the bearings on both sides of the auger and keep it aside. Unscrew the shear bolts that hold the auger in place. Finally, remove the auger from the snow thrower.
