My B8200 has a flow divider. There is a knob that my repair manual says should screw all the way in to get pressure. Mine has a roll pin on the knob and 2 roll pins on the valve. Turn knob ccw and press goes to 0. Turn CW till pin on knob hits roll pin on body and you get pressure. I removed the roll pin in the body and turn CW just a tad more to get max pressure. Turn more cw and pressure goes back down to 0. This valve does not operate like the one in the manual. I am confused. Anyone else run into this?

That is both a diverter valve and relief/pressure regulator valve, but the pressure regulation is not adjustable (by a dial) I do believe, most need shims replace to adjust pressure.
The valve that you are turning is the diverter valve, you turn the valve one direction (to the roll pin stop) to divert flow to hoses that would be hooked to the valve, for like a loader.
If you turn the valve one direction and get 0 pressure you are dead heading the pump and will blow the seals out of the pump, so stop doing that.
Put the roll pin back in as it's a stop.
What exactly are you trying to accomplish or fix?

When I turn the diverter valve to the roll pin, it works the loader ok when oil is cool. When the oil gets hot pressure goes so low the loader is almost unuseable. I got a 3000psi gauge and found the pump was putting out 2300 psi. Then went down stream of the diverter and only found 900 psi. 0 when diverter was opened. Turned the diverter with channel locks that broke the stopping roll pin. Right at 1/16 inch past the position of the stopping roll pin , I get 2000 psi going to the loader. That is when I found if I go past that point, pressure goes back down. Do you know why my repair manual shows a threaded diverter valve and says to screw it all the way in but do not over tighten. I haven't disassembled this diverter but I know it is not constructed same as the one in the repair manual.
