Compressor again...

So, I just had a chance to look at the compressor again. I noticed when viewing the pump it has and arrow on the housing showing a CW rotation but it's turning CCW (as looked at in the photo). Hummmm. So I looked at the compressor again and the big cast iron pulley/fan is (as facing it in the photo--other side of the machine) turning CW/sucking air from the compressor cylinder vs blowing air toward it. This seems wrong. It also seems wrong given the curviture of the fan blades to me. So I'm wondering if the motor is turning the compressor backward and that's the whole problem.

Now as for the motor it says on the data plate it runs CCW but it doesn't say if this is viewed from the pulley end or the other end. If it's the pulley end it's as viewed from the pulley end it's turing CW. So I looked at another compressor I have and it's motor says CCW and it would be doing that viewed from the pulley end.

So I'm thinking this motor is wired to run the wrong direction. I understand they are reversible but I've yet to research how to do that.

Input would be appreciated.

My compressor motors I have state rotation viewing with non pulley end closest to you and pulley end furthest.


There should be some kind of wiring diagram on motor. my 5 hp electric motor has 4 wires inside, two each connect to the line in. You have to swap one wire from each pair to reverse it.
 
I just looked at the pic of the motor tag and there's instructions on the
motor tag to reverse the rotation.
I think that should take care of your problems.

Most pumps are run so the blades on the flywheel blow air onto the cooling fins on the pump. Mostly you want that rotor in your oil pump going the right way around! Vane pump.
 
Seems to me in most cases when they say rotation they say it's the way you see it when facing the shaft.
