I have say that the motor drive assembly is quite simple and bulletproof against putting it together wrong, it only can go together one way. I'll update the roof operation after the fluid arrives Monday.
Note: the pin and spring connects the motor to the pump and drives the pump, make sure the spring doesn't push past the collar on the pin or it will collapse and not drive the pump. While holding the pin in hand, push the spring upward against the pin collar and if it passes over there collar you have to bend the spring END slightly so that it fits tight and doesn't pass over there collar.
Maybe a silly question, but with the spring compressed, does it push the pin into the metal pump or the plastic motor wheel?
