I have drained the oil from all three compartments, removed the PTO shaft and cleaned the rear end housing and attempted to flush the hydraulic compartment. I then added two gallons of new 90 weight to the Hydraulic compartment and put more in transmission. With the inspection cover off, and the quadrant lever in the full lift position, nothing was happening. I used a wrench to move the control valve forward and the arms lifted up. I adjusted the quadrant as far forward as I can get it. In the lift position, the arms raise slowly and with a slightly jerky motion. Standing on the arms it goes down and will lift up slowly. If I use the wrench to move the forks/control valve forward they operate perfectly and more quickly. The arms do not go down until the lever is down about 3 or more inches. This 3pt has not been used in the last 30 years(?). Is there another adjustment or change to be made to get the system to work better or will this hydraulic system "wake up" if I continue to use it?

One furthre note, the only force to move the control valve is the spring from end of lift cylinder to "horseshoe". An ofter overlooked point....takes some observation and thought.

" I adjusted the quadrant as far forward as I can get it." If you really meant adjusted quadrant(4 slotted holes)as far forward as can get it, you went wrong direction! Moving quadrant to rear allows more forward movement of control valve.

That's what I meant and I am glad that you have shared that info with me. I am going to go out and give it another go.

You said, " Is there another adjustment or change to be made to get the system to work better........." Drain the oil, drop the pump and overhaul it. When I took mine apart I found dead grass in the control valve! There is only one way that got in there as far as I know. My point being your pump is 65 years old, give or take. I don't think it's going to get better with use. Oh, and when you refill with oil, use modern UTF.
