So I went out and fired it up again. The Engine is running the pump in the clockwise rotation so the pump is turning in the right direction. So maybe, the pump is worn out like 1oldbuzz suggested. 

So next question. Lol. Will a pump fromm a ccw work on a CW ? I have some ccw pumps that need new input shafts. Maybe just make one out of 2?

I would think the pumps will interchange.  The rotation changes the location of the intake & pressure ports to the pump gears, not the gears themselves.

And yes, this pump has been apart before. The 4 allan head bolts all had washers behind them.

The charge pumps are not the same , you must have the correct one to replace it. It has internal rollers and a directional drive web for them. If it has the wrong parts it simply will not pump. If you think it has been apart, then maybe they assembled it wrong, they could have this web backwards or just simplily forgot the tiny drive pin so the web doesn't spin under a load? In any case, it warrants a removal of the charge pump. My recommendation is to ONLY remove the charge pump and inspect. If you did assemble the entire unit and mix up the pump/motor piston balls..... Your in deep doo-doo ...so just remove the charge pump. There is a manual in the manuals section on how this is done . Good luck, any questions please ask. ;-)

Thanks Keith, I poped the cover off and the Web and rollers are secure and turning the right direction. I hooked a gauge up and I'm only getting 50 psi at full throttle.

The web needs to throw the rollers outward, also did you check the psi right at the pump? You will want a pail handy and a tee fitting to do this test as you will be testing the pumps max pressure. You can use a ball vavle to control flow or a good pair of pluers to squeeze the hose off. Only do this to a max pressure of 800 psi, as that is all it is rated for. If the pressure rises past 500 the pump is good, the valve is your issue, if not.... DOH ! Pump issues..

I couldn't get a "t" so I just unhooked the control valve and installed the gauge to the hose. And only 50psi. So I think it's the pump itself.

Was the oil foamy looking when you were testing?

No, the oil is new and not foaming at all.
