I am a facilities maintenance tech at the Tulsa Whirlpool Manufacturing Plant. We have about 40 York Series A Rooftop Air Handlers. Recently we lost a motor in one of them and need to replace it. A new motor has been ordered, but we wanted to know if there already existed a lifting device to extract the 15 HP motor. Has anyone ever dealt with these before? Can anyone suggest an easy and safe solution to lift out the old motor and put in the new one?
