I'm replacing my stock sc pulley with the one from Poland. The car had an aluminum 65mm pulley on it when I bought it and it failed. I replaced the failed pulley with the stock pulley that came with the car and I had no problem with that project. Now I want to remove the stock pulley to install the Poland IBF pulley and I'm having trouble getting the pulley off.

Any suggestions would be appreciated. I don't want to damage the stock pulley in the process of removing it. TIA Dave
