Outdoor Power Equipment and Small Engines - Auger Pulley on snowblower

Please help ! I have a auger pulley from a craftsman 21 in snowblower model 536885212 that I can't free. I tried liquid wrench , heat , hammer , wrenches , sockets breakerbarand more liquid wrench ,heat , hammer etc. this has been going on for over 3 day's . I keep heating it and cooling it and them giving a little tap on it but no good ! Does anybody have any ideas ?????? :madhell:

feel around inside the groove on the pulley. you're looking for a set screw either over the keyway or 1/4 turn either side of the key. should be a 7/32 allen head - should be pretty easy to turn by now too.

I do not have time to check your model but if it is a single stage blower it has a left hand thread. A two stage will have a set screw on the inner hub. After removing the set screw, I use a ball joint separator tool to remove the pulley from the shaft. I have run into some really damaged hubs on the keyway where the pulley is pratically impossible to remove. Hope this helps.

50 yrs of servicing all makes.

No set screw or anything else . Its a single stage and it has the left hand threads. I'm still trying to remove it . I think i'm going to need a bomb to get it off !! Any more ideas would be helpful !! :madhell:

To get mine off I put a long wrench across the auger, parallel to the shaft to spread out the force over multiple points, then stuck another wrench in the auger with a pipe on it. I had my little brother stand on this pipe. This held the auger still so I could turn the pully.

Then I just used a long wrench and put my weight into it. The threads were left handed.

If it is rusted, I would recommend a product called PB Blaster. It comes in an aerosol can. I use it when working on my car. Sometimes I'll spray down a bolt and let it sit overnight then try to break it free. (my car is 15 years old and rusty)

This would be a good time to use an impact wrench if you are luckey enough to have one.

Good luck
