Thanks for the speedy reply. Yes I used penetrating oil before I went to plan ( B ), the hammer. The auger shaft is very clean, and since it wont move even enough to get close to the set screw make, it must be seized up. Since the augers are rusted to the shaft, previous owner didn't use the shear pins, I'll have to torch them to get them off anyway. Glad to know there is nothing else holding that shaft. I didn't see anything in the diagram that would hold it. Thanks again.

Thank you for the update. I am sorry that you are having so much trouble getting the bearing and shaft removed from each other. You may be right in having to use heat because it sounds like in you description that the bearing race has seized onto the auger drive shaft. If you can move the shaft side ways on the bearing it may have overheated the race and it is now stuck onto the drive shaft.

If you made sure the set screw mark have be filed flat so the shaft will slide through the bearing race then it looks like heat is the answer. There is nothing else that is holding it. Have you tried using some penetrating oil?

Again I am sorry you are having so much trouble with the removal of the auger drive shaft.

Thank you for using Manage My Life.

Having done all this, the auger shaft will not move. I have even used a heavy hammer with a block of wood so as not to damage the shaft, and it will not budge. The shaft does move side to side in the bearing, moving the auger assembly from the front. So it appears to be loose, but will not move out of the bearing. Being a machine repair man for over 30 years, this should be very easy. The only thing I can figure out is to heat the shaft and or bearing with a torch and see if it will move. I can always replace the bearing. I just want to make sure there is nothing else holding in that shaft.

Thank you for your question.

Working on snow-throwers can be a challenge.

You will need to separate the snow-thrower housing in the middle to get to the drive and remove the auger housing from the front.

Locate and remove the bolts holding the end bearings on both sides of the housing for the auger.

Open the belt cover and remove the front belt on the drive system for the auger drive.

Separate the auger housing from the drive system just in front of the drive wheels. Take out the top bolts and just loosen the bottom bolts so you can break away the front from the rear half.

Remove the drive pulley from the auger shaft and make sure the set screw mark on the shaft is smooth so you can slide it threw the bearing support and pull out the auger drive from the front to clear the housing.

Replace the auger and re-install assembly.

I hope this procedure will help with your repair.
