I think k5lqw has the correct diagnosis. Curious to see if this solves your issues today.
I removed the plug in the photo attached and installed the “regular “ plug. The loader and tractor now work as advertised. I have the pressure gauge on order and will reset the regulator. I greatly appreciate the help. I’ll read up on hydraulic systems to avoid these errors of ignorance going forward.

Great to hear! Save that sleeve! If you ever want to add another valve that will provide an easy way to do it. Getting the correct PB sleeve after the fact can be very challenging.

Yup, save that sleeve and use it for installing rear remotes so you can get a Top'n'tilt kit

You have an OPEN CENTER system. The pump is positive displacement. the output of the pump must flow thru the system constantly, from the pump back to the reservoir. When you move the valve the oil is simply directed to the cylinder or motor that the hoses go to. The returning oil from the cylinder is sent back to the reservoir.
An open center system MUST have a relief valve, if it does not or is set too high---Somethings going to break, a hose, the pump, the pump drive, the cylinder, or even the valve.
The control valve usually can be configured many ways. One way is as your valve is hooked up. That fitting you took out is what is called power beyond it is used to send oil to another valve such as a backhoe.
The pump does not create pressure, the load or restriction does, the pump only moves oil.
The valve "tells" the oil which way to go.
The cylinder or motor does the work.
It is all connected to together by hoses.
In a hydraulic system the pressure is the same throughout the system. If it takes 2500PSI to lift the load it will be the same at the outlet of the pump to the cylinder doing the lifting
This may or may not help you understand a little about hydraulics, but recommend searching for Basic Hydraulics and picking a site that helps you understand the basics.

Guys,
I have a 6530C with the EXACT same issues that Steve posted originally back in 2022. I got the tractor used where it had some damage, but was told that the guy "mowed a lot of brush". I think they wrecked it, got it working as best they could and then unloaded it on a poor honest fellow like myself.
I want to get it working right and have been scratching my head. While I'm idling it constantly sounds like the pressure relief valve is operating, and the engine seems more labored than when operating the FEL. The hydraulic lines will get really hot, even if I'm not operating the 3pt or loader.
Even the other issues that Steve has described I'm seeing. But, the pictures of his new valve look different than mine, and I have a copy of the hydralic schematics for the tractor, and even those look like a different valve. I'm wondering if the guy put the incorrect valve on. And, if so, could I fix this one so that it's working right, or go spend the money to buy the correct valve...
I was wondering if you guys were still around, if you'd be willing to help? I can grab some pictures and get some video of the bogging, and close ups of the ports on the valve and the schematics. Just what would be a good starting point?

Photos always help. Closeups are good, but so are details of where lines come from and where they go. Also, does it make any difference if the three point is not fully up? On some tractors that is a factor.
