After replacing the cooling motor fan on my Can Am Commander I decided to take a few minutes and take it apart to see why it failed. I was surprised to see the reason of the failure was such a small problem. In my opinion, the motors are expected to take on a certain amount of water and they are design to evacuate the water through a vent tube. So why would a manufacturer use non stainless brushes? Check it out to see what's left of the springs.
