Cooling Tower in Philadelphia
Every year the fan motors needed replaced. So the mechanics took off the fans, replaced the motors and reinstalled the fans. This was repeated each year.
But motors should last longer?
Yes.
Eventually someone discovered the fans were out of balance and that caused the motor bearings to fail each year. Replacing the fan blades solved the root cause of the problem.
