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.

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 !!

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
