John Deere Power Beyond Questions

[LD1]

Not familiar with your particular machine so I don't want to make an incorrect statement.

But I assume where you unhook A from B.....is where you "splice" in your supply and PB for the backhoe. And return off backhoe has to go to a return to tank port somewhere....

I think you are correct. I am just wondering if it matters which one is attached to the "loop" first, PB or P?

Yes it matters

Well I am hoping someone will enlighten me :anyone:

P or pressure is the valve inlet

PB or power beyond is the valve outlet to the valve down stream in series. Example: FEL PB port connects to the back hoe P port. Back hoe PB connects to the 3PH P port.

Re: John Deere 850 Power Beyond / 3PT hitch Questions

I have a new to me John Deere 850 with power steering and power beyond factory installed. I have the seat removed and am attempting to trouble shoot the 3PT hitch raising itself. I believe a relief is dirty or damaged and is bypassing. . I have not changed the hydraulic filter or cleaned the screen yet that is tonight's project. I would appreciate any guidance as to which valve may be suspect. I would like to remove the power beyond selector valve completely since I do not need it and it has not been used for many years. Any help with tying the pressure line and relief line back in would be helpful. I have the technical manual ( thanks to Joe C ) I have attached a few photo's ( at least I hope I did ) thanks much for any help in advance. To you hydraulic experts I am a gasfitter by trade and am familiar with troubleshooting using gauges but do not have gauges for troubleshooting hydraulic systems and would appreciate any recommendations as to where to purchase .

Thanks in advance

Jack

Hi Jack - Might want to start a new thread.
Not sure many folks will see your question.
Good Luck!
