Remove Auger from Craftsman Snowblower

Hi Folks:
New on the site but very interesting forum. I have a 10.5hp/29 inch blade Craftsman snowblower. I want to take the AUGERS off to get the holes for the shear pins rewelded as they are bigger then the pin side and are causing the pin to shear off way to often. I took the auger housing apart but cannot get the pulley off. It is on there and on good. Tried to heat it with a touch but no joy. The pulley has a square key in it but I can't get it out. It almost looks like the pulley is screwed on. Anyone help as this looks like it should have been an easy project. Anyone with experience out there. Would appreciate all comments.
Thanks
Steve

Did you remove the set screws that hold the pulley to the shaft? If so then all you can do is apply some penetrating fluid and let it sit plus continue to use heat. If you apply too much heat, you'll most likely have to replace the bearing that is located behind the pulley also. Worst case scenario would be that you'd have to cut the pulley off and purchase a new one. Either way, when you get it off, clean the shaft real good and put some never seize on before installing the new one.

Appreciate your time. On this craftsman there is no set screw on the pulley. I have been using WD40 to lubicate it with no results. I might have to cut it off but would hope I don't have to. Will try more heat. Any suggestions on good lube to loosen it up.

Can you post the model and serial of your snow blower, I would like to see if I can see a breakdown of it on the Sears site.
What is actually holding the pulley on? Is it a bolt going through the shaft?

Has to be something !!!

Has to be some kind of set screw holding the pulley in place, if not in some instances had to use a puller to remove(with some heat)

remove auger from craftsman snowblower

Steve:
Make sure to look on both sides of the pulley,for allen (set) screws,maybe 1, maybe 2- 90 degrees from each other, 1 should be on top of the key-way. If they are there, soak with pentrating spray and remove. If all else fails, it might just be pressed on, Don't know for sure.

Thanks to all:
Had to do it the hard way. A pulley puller would not take it off. I ended up cutting it off and putting a new pulley on it. I actually end up drilling in holes on the augers for the spear pins. Used it here in Nova Scotia three times now, works like a charm. Had to go to a high grade shear pin for the gears. Talk with a bolts and nuts company and they stated they couldn't believe the amount of people coming in for a stronger shear pin because they are breaking off on the gear drive so easily. Manufacturer are making things cheaper all the time. Snowblower working great now. Thanks again all.

You may want to reconsider using non-original shear bolts. They have a specific job to do. Yes, they may shear easily. Better for this to happen than to use a "stronger" bolt and have the gearbox disintigrate. The hole being larger on one side of the auger than on the other is by design. The correct shear bolt has a shoulder which fits into this larger diameter hole. Also, never crank the nut completely tight. The nut on a correct shear bolt will be a locknut. Again, for a reason. Tighten the nut up snug then back it off a half turn. This allows play and therby alllows the shear bolt to do its job properly...shear!!!
