Claas 66 round baler

What is the required hydraulic pressure needed for the claas 66 round baler to work correctly. My tractor has 2350 psi on it. It leaks just slightly, but I'm in the process of rebuilding the remotes on my tractor. My concern is to keep the back door of the baler shut when the bale is still inside and I get ready to wrap. Thanks for any help in this matter!
 
You'll be fine. What is important is that you keep the valves themselves tight and reasonably free of leaks and the baler hydraulic tight. The baler will make pressure well beyond the nominal system pressure of any tractor... It just needs a tight valve to make pressure against. The door makes it's own pressure when the system is charged by forcing the door open slightly and compressing the fluid in the lines...

Our 4230 one remote always leaked down a tad.I always just kept hitting the remote .I always watched the gauge and always had good bales.
 
Those balers have a valve in the tongue that has a check valve and pressure relief valve that builds/holds the pressure on the bale. The door will be open a few inches when you are baling with them. That is the only way they will work.

Your leaking SCV will make the baler not work if it is putting any pressure on the lift side of the baler door. This will not allow the check valve to close and build pressure. A way to check the baler system is to close the door and hold the pressure on the close side until the pressure gauge is a high as your tractor will go. Then unhook the return line from your SCV. IF the baler makes a tight bale then your SCV valve is causing the trouble. IF the baler still does not build pressure then the check valve/pressure relief valve on the baler is not working.
