what kind of pulley remover are you using? I have a zzp pulley removal and have had no problems. Just make sure you have the pin in the hole at the end of the supercharger shaft even and the 2 pieces that hold the pulley on there tight and start turning the bolt...it should turn fairly easily but will take a while before it finally comes off. If your using a zzp puller or one like it i have a full set of instructions i can email to you if you want, just ket me know.
