Hello Mike, how are you? Taking your posting in stages; The control spring plunger should be tightened until the spring is stiff to turn by hand. When checking this insert a punch or thin screwdriver into the pin hole so that it does not tighten. When adjusting the control spring nut the DRAFT lever must be in the fully lowered position. Adjust the nut until endfloat just disappears. Any further and it will reappear. When you go into the PRESSURE CONTROL part of the quadrant and cannot lower the lift arms, do you have any implement attached or just the empty arms. Pressure Control will vary the pressure from about 500psi to blow-off pressure. The system cannot work at zero pressure when in PC low. This pressure is around 1/6th of the available pressure. It takes far less than that to lift the empty linkage. 500psi was enough to lift my concrete counterbalance! When the divertor valve is switched to the loader you have effectively sealed off the 3-point lift circuit. There may be some leakage past your DV but the bulk will escape past the seals/rings in the lift cylinder. This is quite normal unless it is falling in less than 3 to 5 minutes. Partly drain the oil and remoce the RH side cover. Reaching inside and upwards you will find the PC adjuster barrel. It has quite sharp 'teeth' around the outside at the lower end. Do not turn it but check that it moves up and down when you operate the PC lever. The action is to increase the load on a spring and valve inside the housing.(When in the POSITION CONTROL quadrant the spring remains fully compressed at its adjustment. A pressure gauge would be a good investment as you will need one if you carry out the adjustment sequence. You will require a gauge to read to at least 3500psi. Hope this helps. Let us know.
