Bring the motor and fan blade to the store, let the counter
man figure it out. I've always found that "bring the part
in" is always the way to go.

I have a 25 year old York A/C heat pump and the outdoor unit
has a slight
vibration. I see that one of the fan blades is cracked. I
tried to
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
money)

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
discharge side.

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?

If I get a universal reversible motor, then does it really
matter which
blade I use, can I simply connect the motor so the blade
turns the right
way?

thanks
