Q:

how to change snow blower auger for Lawn Boy 522r?

A:

Thank you for your question.

Replacing the augers on a snow blower is not an easy repair. If you are set on repairing the blower your self please follow the steps below.

  1. Remove the spark plug wire and belt cover.

  1. Disconnect the chute control rod.

  1. Remove the belt and the auger control cable if it is attached to the blower head.

  1. Locate and remove the bolts that attach the blower head to the drive assembly.

  1. Once the blower head is removed tip it onto the nose so the pulley is up.

  1. 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.

  1. Once the pulley is removed you can remove the bolt 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 paper before trying to move the bearing. You might also need to use a puller here also.
  2. Remove the bolts securing the bearing for the left and right auger shaft. Then slide the whole assembly out of the blower housing.

  1. 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 get reversed, the snow will not get 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.

  1. Just reverse the above steps to reassemble the snow blower.

I hope this is helpful.

Thank you for the reply. You are right not a real difficult repair just time consuming. I can not stress enough use emery cloth to clean the shafts and do not hit the end of the shafts with a hammer. This will mushroom the end of the shaft and then you might not get it apart. Good luck to you on the repair.

I have looked up both augers and the cost for both is $148.74. We have a flat rate shop fee of $64.99. This fee covers all the labor. That would put the repair about $235.00 with tax. If the rest of the blower is in good condition, I recommend having it repaired. The reason is a new blower will cost a bit more than $235.00. I have posted a link below that will show you the nearest drop off location. I hope this is helpful. Please let me know if you need further assistance. Thank you for using Manage my life. Mark T.

I am glad to hear you have gotten the snow blower back together. The engine requires roughly 20 ounces of 5W30 motor oil. As for the gears you can you can use a marine grade grease to lightly coat them. Do not use too much because it could sling onto a belt and cause it to slip. For the axle bushings, I recommend using spray lithium grease. The grease comes out of the can like water so it can get into tight places. Then the thinning agent evaporates and you are left with thick grease in those places.
