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

Hi,
The air flow sgould be upward. I think if you really want to remove the
blade just soak the seized part on the shaft with generous WD40 , let it
work it's way a few hours, repeat in needed then bearing puller....

The rotation of a motor is viewed by looking at the front of the motor
unless otherwise specified.

It is determined by looking at the end opposite the shaft

The OP asked about the blade!

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.

Yes, airflow upward. But, is WD a lubricant, or a water
displacer? What happens if you put the fan in upside down?

Sometimes fans are double set-screwed (one on top of the other).

If you can get the set screw loosened, a bit of heat on the
hub may help loosen the fan blade. Bearing puller might
help.

Bring the fan blade with you to Grainger, to match it up.

Hi,

let it work it's way a few hours, repeat in needed then bearing puller....

Better than WD-40 is Liquid Wrench. Probably sold at the same place as
WD-40, or an auto parts store.
Let it sit for a while and try to remove it. If it still won't come off,
tap the end of the shaft with a hammer a few times.
If that fails, apply heat from a propane torch.

Better than WD-40 or Liquid Wrench is PB Blaster. Squirt some on it, repeat
whenever you remember, and come back the next day to remove it. You might
still have to tap it with something.

If that doesn't work, try the heat/cool approach with a torch, just don't
heat the shaft long enough to fry the bearings.

Yes. And Ken answered the question. On most setups, the blade turns the
same direction as the motor.

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).
