I am trying to remove the drive pulley from a ND-Denso (10P?17?) compressor (from an old 1992 Camry 5SFE) so that the bearing can be replaced. I just cannot get that outer clutch face plate to come off. I have already removed the 10mm bolt on the end and I believe it should just come right off (so that I can then get to the snap ring which holds on the pulley). However, this outer clutch plate just will not come off. You cannot get to the backside of it at all since it is recessed inside the pulley itself. I've sprayed it with penetrating oil, I've hit on it with a rubber hammer and a brass drift. I tried pulling/prying on the back side with a couple of nail heads inserted into the small gap (until I bent the plate edge) and I finally screwed a bolt into the center of it and tied a wire around the bolt to hold the unit as I bounced it up and down thinking that all of that weight of the compressor would surely jar off the outer clutch plate. Still, no luck at all after half a day of messing with it. The 10mm bolt is out so what could be holding this plate on (rust?) and what should I try next to get it off?
