Can the fan become imbalanced that easily? My fan was bent, so I bent it back! Put it on and have been driving it since. Should I worry about damaging the water pump bearing? Or could it create a rough idle?<hr></blockquote>
Here is a thought from an experience I had. You might want to be worried more about serious injury.
My "B" had a metal fan and one of the blades came off while I was driving home from work one day. Not going fast, just normal speed. I didn't know what it was at first but that it made a loud bang and suddenly the car started vibrating badly. I stopped and found the blade sticking through the metal side where the inner fender is. Had this come off when I was reving the motor and looking down into the engine bay, and the angle of flight had been a little higher, I would not be here today. That had enough force to have penetrated well into my brain. The area it penetrated the fender well was just in front of the carburators.
