I have a 25 year old York A/C heat pump and the outdoor unit has a slight

remove the fan blade from the motor but of course it is rusted on tight. So
I will replace both the motor and the fan.
(Please no lectures about how I should replace the entire unit to save
The motor is 208/230 Volt 0.5 HP 1075 RPM standard frame 48 motor.
The blade is a 22" diameter 4 square blades. I don't know the pitch.
I see Grainger has the stuff I need, their fans are REVCOR which is even
the same brand as the original. They have a 22" diameter REVCOR blade
rated for 0.5 HP so that is probably what I need. Grainger has what looks
like the blade I need in both CW and CCW style. The original fan I have
turns CW when viewed from the top which is also the motor side and also the
How is the CW. vs CCW specified for fans. Is it viewed from the intake
side or the discharge side, or from the hub or not hub side or?

blade I use, can I simply connect the motor so the blade turns the right
