Thank you for your question.

Most of the time to replace the impeller pins you have to remove the auger assembly from the auger housing. i will explain how to do that further in the reply. I have a customer reply back to me the other day saying he was able to replace the pins by removing the discharge chute. he removed the chute and used hammer and a 2 foot rod he purchased from the hardware store to remove and install the impeller pins. He put the rod down the outlet and turned the impeller pulley until hole was aligned with the rod. Then tapped the rod with the hammer to remove the broken pin. Then had a helper hold the new pin with a pair of pliers while he tapped it in. if this does not work you have to remove the whole assembly. Removing the auger assembly on a snow blower is not an easy repair that is usually done by a service technician. If you decide to repair 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.

Once the augers are removed you can split the gear case and replace the auger shaft.

Make sure to clean all the old grease out of the case and repack it with high quality grease.

Just reverse the above steps to reassemble the snow blower.

I have found a video that should give you a little more confidence in doing the repair.

Mark, thanks for you thorough treatment of the Impeller roll pin replacement. I studied and agonized over it for two days before finding your answer above to another customer. After a quick view of the chute removal solution for access to the pins, I decided not to dismantle anything. I drilled a 3/8" hole in the impeller cowl, directly over the roll pin holes. A piece of 1/4" steel rod served nicely for a drift punch, and the pin remnants were out on less than a minute. I purchased two 1/4" X 1 1/2" roll pins at the local Cal Ranch store for $.45 each. Then I drilled a 1/4" hole through a 1" piece of oak dowel I found in my shop, and aligned the pins and the punch in the dowel to install the new pins - about three minutes with no problems. Now I have a question for you:

Should I plug the hole in the impeller cowl, or do you think it will make any difference in the performance of the snow thrower? I'm not worried about rust, as the interior of the cowl has been scoured by gravel and debris for several years and is almost paint-free.

Thanks for your help. It led me to a solution that saved a ton of money and time.

I am glad to hear you were able to find an easier way to install the pins. I would not think the holes in the cowl would cause you any problems. If you wanted to plug the hole, you might be able to find a rubber plug at the hardware store. Please let me know if you need further assistance.

Thank you for using Manage my life.

I had a similar problem and taking the snowblower apart was not something i wanted to take on. I aligned the roll pin hole with the discharge chute, and with a long metal drill bit drilled thru a NEW hole. I then was able to put in a regular sheer pin and i was good to go. It takes a little effort as it is still a tight working area
