After stretching the life of the combination condensor-evaporator fan motor on our 28 year old Coleman roof top air conditioner, and after purchasing a motor that would fit if I built a new motor mount, I found this motor. It's a direct drop in replacement, the motor capacitor wiring is slightly different but if you mind your pees and ques not an issue.

2-speed. We have the light weight entry level Unihome with the Torsionaire suspension. Drives like a sports car.
Good info here. Might need it someday. I too am a fan of Johnstone Supply and Grainger has never let me down.
