i only hope the bolt has not stripped while you were loosening. try adding some grease to the exposed threads and retighten. try loosening again. is the bolt hitting against anything?.if you are successful do you need a puller tool to remove the pulley because they sometimes are an interference fit. also before removal is there any timing marks that should be noted.i hope this has helped you my friend.
