Finally got around trying to fix my old warn winch, bought it used back in 2010, worked hard all that time but salted roads here in Quebec, Canada finally did it in, pulled it a few years ago but never got around to tearing it apart. Finally did it this afternoon, the motor end cap was badly corroded, blew out lots corrosion inside the motor and I was finally able to turn it by hand, rehooked up all the cables and the motor is still alive, now I need a new endcap and gaskets to rebuild it, but WARN asks for the serial number but I think mine`s corroded off the transmission end cap. any way to identify using the motor numbers?
