Hi, I purchased a 1981 Gl500 when removing the radiator to paint it I noticed the fan was in pieces. I ordered a replacement but am now trying to take the old off from the shaft and am having a hard time. It was full of grime and dirt and strangely spider sacks that I removed with engine cleaner but using pliers and anything else I can use to try and pry it out it will not budge. Is there an easy way I am missing? The only thing I have managed to do us tear into the cheap metallic look center piece. I already received the replacement, unfortunately I read about the electric conversion a little late so I will wait on that until this one is about to give. Any suggestions?
