Thank you for your question.
Replacing the auger on a snow blower is not an easy repair that is usually done by a service technician. If you are set on repairing the blower yourself, please follow the steps below.
Remove the spark plug wire and belt cover.
Disconnect the chute control rod.
Remove the belt and the auger control cable if it is attached to the blower head.
Locate and remove the bolts that attach the blower head to the drive assembly.
Once the blower head is removed tip it onto the nose so the pulley is up.
Remove the pulley from the shaft. It should have a set screw on the backside, maybe two. I recommend spraying the shaft and pulley with a penetrating oil to help with removal. I have seen in some cases a puller is needed to remove the pulley because of rust.
Once the pulley is removed you can remove the bolts securing the bearing. Then slide the bearing off the shaft. This can be difficult to do if the shaft is rusted. I recommend cleaning the shaft with emery cloth before trying to move the bearing. You might also need to use a puller here also.
Remove the bolts securing the bearing for the left and right auger shaft. Then slide the whole assembly out of the blower housing.
Remove the shear bolts and remove the augers. Make sure to mark the augers left and right so you do not get them mixed up. If they are reversed, the snow will not be pulled into the impeller. Most of the time I fine the augers are rusted to the shaft so you might need to spray it down with penetrating oil and let it sit over night. If they do not come off you may have to heat them up to break then loose.
Just reverse the above steps to reassemble the snow blower.
I hope this is helpful.
