One of our SP-15 motors (Vandercook # 22155) quit last week. It has been noisy (our other SP-15 is about as loud as a sewing machine) but lately the noise was worse, and then the motor just stopped, smelling burned. The motor refurbishing place (Evans) tells me that there is a seal in the gear box that is leaking. He asked me if I could find out the model and serial number of the gear box (different from that of the motor). They can’t really fix that seal without it, they tell me. Does anyone know of a way to get this information?
