Trouble with zetor

[dubster12]

Having hydraulic problem . Got a 7745 with an aftermarket (allied ) loader . Have 2000lbs pressure at the valve . Cylinders are rebuilt so is valves will pick up bucket empty but not with a load .Ive tried everything . Any ideas. Its got 14 gallons of fluid cant imagine that not being enough. Over half way up the stick .

I"m not an allied loader guy, but most loaders have a pressure relief valve that limits the lift capacity, yours may be out of adjustment (you mention rebuilding the valve). the valve is adjusted to kick off at a certain pressure.
