I am trying to remove/replace an alternator on my 2001 986S. I have Wayne's book. He describes tapping the idler pulley to remove a bushing. I don't understand the significance of this. My new alternator has this bushing installed already. I don't see how it is possible to remove the alternator. I removed the lower mount bolt. I can't remove the upper mount bolt because it is so long that it hits the firewall. I'm trying to pry the alternator up from from where the pulley bolt rests but it doesn't budge. Getting worried...
