Not sure if anyone can help me or not. I stumbled upon an old Sachs 440 twin fan motor that needs some attention. I can't find much info on these motors. The model of this motor is SA2-440. I've found parts but they are off of a Sachs 440 twin fan with a model of SA2-440C. What is the difference between these two motors? Can anyone help me or direct me to someone or place that can help me?
