Believed the condensor motor was defective and causing strange odor

First disconnected the quick release electrical connection. Then loosened the three screws that were holding the motor in the bracket. However, space is limited and even with small hands it was rather difficult as the screws were in there very tight. There are a few sharp edges on the bracket and in the surrounding area of the motor area, and nicked myself a couple of times. Removed the fan blade from the old motor and attached it the new motor with the old flat washer/screw. Reconnected the electrical connection and that was that. All-in-all an easy repair.
