Thanks Matt, for giving me all these suggestions. The belt grooved pulley does spin freely. I did not try to turn the clutch with the plugs out, I'll try that tomorrow. That may be the trick. It has 3 oz of Pag oil in it and it calls for R134. I bought a pump like this one last year and it lasted only 6 hours. The guy at O'Rilleys said that I didn't put enough oil in it and that is why it locked up. Now I have this replacement, same model, that I want to make sure it doesn't happen again. The 1st guy that sold me the 1st pump said it had enough oil in it now the 2nd guy says it didn't. I'm not sure. Just don't want to go through this again because the change out is a real b***ch. Really hard to get to. I have skint places to prove it!
Thanks again.............Hal
