Craftsman 5/22 auger seized. Tried everything!

I have my dad's old ~1999 Craftsman snowblower that I rescued from going to the junkyard in 2014.

Model #: 536.886540
Code: 321502661
Engine: Tecumseh HS50

I got the engine running like new but now the auger gear is stripped. I'm trying to remove the augers but they're rusted on tight.

I've tried all the techniques I saw on here: soaking them in Deep Creep multiple days from the ends and through the shear pin holes and banging them out, using the pullers in the pics, borrowed from Autozone but they don't fit great.

I tried electrolysis on one side but that didn't help (see setup in pic).

I tried the 2x4 method but that has just cut grooves in my 2x4. I even tried prying it off against the impeller shaft but that just bent the auger.

I don't want to give up but I am at a loss as to what I can do. Any help is appreciated!

Hang in there with the Heat and penetrating oil. At a minimum, use Mapp gas; propane isn't hot enough.

Try Kroil, Liquid Wrench, PB blaster or a homemade concoction of acetone/ATF (50/50).

(deep creep is not a penetrating oil... it's seafoam in aerosol form).

A Lot of what I've used in the past along with a hydraulic press. Put it on end, heat and use penetrant, rap it some with a big hammer and try pressure using the hydraulic press. May use something cold at times to heat shock it too. Biggest thing is attempting to break the bond between the auger rakes and the auger shaft
Another thing I've heard to work on the steel parts is electrolysis. Big thing is don't immerse it to the point of getting the auger gearcase wet as that could lead to other problems.

I've put out a pdf on how I've done it in the past and gotten rusted on auger rakes off.

Here's what someone else described using an air hammer, but it sounds like he may not have had the auger removed yet...I could be wrong, though.

Thanks for all the tips. I don't have access to an oxyacetalyne torch but good suggestion on talking to a car shop. I did hear you need at least MAPP gas. Will this Benzo torch in the pic be enough?

That's interesting on deep creep. I had some and saw this video so I figured it should be good. I think I'll still get some Liquid Wrench because it performs even better.


I have seen those Donyboy videos - he's great. I was hoping not to have to mangle the auger shaft like he did.

I might try to fashion a puller like I saw on here. Seem like that method should be effective.
