My 1985 JD 318 S/N M00318X31928 has a Transmission Fluid leak in center of tractor right behind Brake pedals. I have isolated the leak to the Power Steering Control Valve and started removal. I have reached a point where the valve is fully in view and the 4 mounting nuts removed. Lines are still attached at bottom but cannot move steering wheel/ valve out of the mounting bracket because 4 bolts protrude thru the bracket. Cannot get to lines with a conventional wrench to remove those to allow the valve to move down and out.
Is there a special wrench to remove the lines or is there a way to remove the 4 bolts without the valve coming apart? Anyone had any experience with removing this Control Valve?
