A.O. Smith STS1072R 2 speed motor is usually mentioned on this forum as a replacement for hayward super pump, but it's 230v only. I was wondering if this motor
Century B973 3/4-1/8 HP 115 V 13.6/3.9 Amps 6 3/8 dia. Frame Century 2 Speed Pool Pump Motor - B973
would fit superpump 56J frame? it mentions that it's 6 3/8 diameter frame on the site above, but on http://www.poolcenter.com/motor_parts.htm it mentions it having 56J frame, so i'm wondering if 6 3/8 diameter frame and 56J frame is the same thing?
does anyone know if it has a high/slow speed switch or if one can be easily fitted?
