2 stage snowblower disassembly question

[Panther416-8 341]

I'm disassembling my 79361 snowblower and not sure how to slide the augers off. I took off the side plates, removed shear bolts and the single bolt that threads into the end of the shaft that the auger rides on.  How does the piece in the center of the photo come of the shaft? Is it something pressed on to the shaft?

Never worked on one but the ipl shows a bearing which looks more like a brass bushing so it should pull off.

You may have room to replace the assembly with a cast iron pillow-block bearing if the shaft is a common diameter.

Thanks gwest, i see that the part 20-0980 is listed as a bearing and still available from a few sources including partstree. It looks like I might be able to get the tip of a crowbar or some sort of prybar between the end of the auger and the bearing. Just didn't want to try anything until I've heard from folks that removed these before.  Also it seems that the bearing on one side sits out flush with the shaft and on the other side its about 3/16" in from the end of the shaft. Anyone know how far on to the shafts the bearing should be or does installing the outer bearing flange and tightening down set the bearing location on the shaft?

 Thanks.

Those bearing should be dripping from penetrating oil for some time to free them.  You may not need new ones, just get them off and clean everything.  There will be some play once you get the rust out, so no need to worry about centering the auger.  In the future, put some oil on to prevent rust, especially for off season storage.

Thanks lynnmor.  I will start soaking them heavily with PB Blaster. Hopefully they will come off without too much effort come the weekend.

Got a torch?

 

I find that heating stuff up, then rapidly cooling will often break the brown welds.

 

To cool quickly, I head to the dollar store and purchase a few cans of "Electronic Duster" spray.  When you invert the can it sprays liquid that will act as a 'freeze spray'

 

I would heat the ball, and cool the shaft.

Thanks all. Tried a cheap two jaw puller from Advance Auto but it was of such poor quality that the arms bent and slipped off the the backside of the bearing as it is almost sperical. I was able to get the bearings off but I had to cut the inside bearing support in order to get a pipe wrench on them and was able to rotate them while pulling the wrench towards me allowing them to slide off the shaft. New parts on the way. Now I have to figure out how to maintenance the auger gearbox and the impeller bearing if there is one but I started a new thread for that.
