recently bought a 93 bonneville. the supercharger sounds horrible. its making all kinds of noise. I am trying to decide to rebuilt it or just get a used one. ive read about doing the grease fitting thing to remove the rotor needle bearings. I was wondering if anyone had tried compressed air at all. I have an end on my blow gun made out of rubber and was wondering it that might work. if not is there any other way of getting them out????

could just be your cuppler.
