Posting a picture John although not as clear as I would like. Lever that has several white marks pushes the 2 pins just above the two single white marks when the control lever is pushed forward. Can just see the shiny ends I think. Pins push balls off a seat to let hydraulic fluid come back to the unit from the ports. Pressure pushes the balls off the seats when pumping into the lines. Unless the pins are pushed in fluid is not supposed to flow back after a load is on the cylinder. When the control rod is stopped on the catch bump its usually several inches from pushing a pin in. Also the more load thats on a cylinder the harder it gets to push the ball or balls off the seats when pushing the rod forward. If the unit won't stay up the balls are leaking or a internal leak. Or maybe the linkage is keeping the pins pushed in, kind of doubt it though. Wonder if dirt, metal cuttings, teflon tape, ETC. got into the ports when changing and is now keeping the balls from sealing.
