Default Condenser Fan replacement CW or CCW which end is it viewed

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?


Go to the auto parts store and ask for some "frozen bolt lubricant." There
are several products that are cheap and work amazingly well on rusted-shut
stuff. Less than five bucks (I'll wager a new motor would cost more than
that - especially at Grainger's).
