I am swaping my Alta 15% for a19% but I cannot remove the 15% pulley from the SC, how can I do it?
Looks like it is seized, even using 2 screws to try loosing it did did the job... will a heat gun help?
Please someone help, I spent the last hour trying to remove it ...

 

 

did you try using those longer screws to slowly push the pulley off the hub? If thats what you were tlaking about in regard to the "screws" then i dont know what to say... Good luck!

 

The problem with a heat gun is that you may expand both the pulley and the hub, especially if they are in close contact. But I don't think there's any real harm in trying it... except that a hot pulley will not be so easy to work with by hand.

I would remove all four bolts and, if the pulley still seems stuck (pull hard now!) I would then use a *small* deadblow hammer VERY LIGHTLY to encourage the pulley to pop off (strike in a direction as parallel as possible (not perpendicular) to the supercharger shaft, and away from the supercharger, if you can). Once it's off, make sure the hub portion is slid back all the way on the supercharger shaft...

 

When I swapped mine out, I had to use longer screws. The four screws that holds the pulley in aren't long enough. They are long enough to leave marks on the face of the hub, but not long enough to push the pulley off. Get some that are 10mm longer and it works fine!

 

Go to the hardware store & get 2 longer screws or give it a tap with a plastic hammer ( the kind with a rubber & plastic head ). It will come off.....

 

wow just finished after another hour try...
I did use longer screw and heat gun to get it loose, look like I have been over cautious when I fitted the 15% a year ago, there was loctite that spread between the outer halve and the inner halve wich kind of glued them... evrything fine now.
Thanks for the help
