Thanks for all the input. I am new to hydraulics. I should have told you it is a 772 series Ford Loader, with a Gensen control valve, no quick couplers, when lifted all the way up rod looks straight. When lowering it sounds like the relief valve is letting loose but lifts a fully loaded bucket with no sound from relief valve. The only way to lower the bucket is to repeatedly pull and release control lever. And it takes a long time to lower. I'm not sure if the return is through the filter it looks to be unless it returns through the pump.What I was trying to say about restriction, is it seems to be restricted somewhere.I recently had one lift clyinder rebuilt and the packing was a mess in there. Could it have cloged the control valve somewhere if so why does the tilt work, and when I changed lines to the tilt side it still wouldn't lower.
