How to remove a snow blower impeller?

I have a 917.881151 craftsman snow blower. the impeller is bad on the unit and would like to replace it. I have pulled apart the unit and have the pulley off the back so I have access to the flange bearing assembly, however, I do not know how to remove the impeller from the auger shaft. The shaft will not slide out of the flange bearing assembly (don't know if it should or not to begin with). I have removed all the bolts connecting the impeller to the auger shaft and the auger bearings are also detached from the sides of the housing... Just don't know how to get the impeller off the shaft to replace it.... and the snow is coming soon!!! .... Please help:-)

If you have the auger shaft bearings loose then the augers, gear box, and impeller should all pull forward out of the housing. It is likely that the input shaft has seized up in the bearing behind the pulley. You can put some penetrating oil on the shaft around the bearing and allow it to soak in good then see if you can pull the assembly out of the housing. If it still will not come out you will need to use a hammer to drive the shaft out of the bearing. Be careful to not damage the shaft. It is "mushrooms" from the hammer, you will need to use a grinder to grind down the "mushroom" to put the shaft back in.
