Good morning all. I have a Harman P61A thats about 8 years old. The beast is making the devils own racket and I've determined that it's coming from the Distribution blower/fan blade. I replaced the fan blade three years ago and all was well. However the squeaking and squawking is back with a vengeance! lol.. Any way when I removed the blower I couldn't remove the fan blade. The hex nut was wedged in there solid. After a good ten minutes of pushing and pulling , the nut stripped and I can't get it out. Any Ideas? The motor seems to be fine. Thanks in advance.
