If the cylinders are leaking internally the loader will not hold position, that is the frame will drop or the bucket will dump with the control in neutral. If you suspect it is an internal leak use a piece of pipe, screwdiver, or what ever place it against the cylinder and you will hear the oil bypassing.They are leaking internally, not externally. When I first got the tractor, when picking up something heavy with my forks, I could lift the loaded rear tires off the ground, even if I had my rear blade on it. Wouldn't happen if I had the backhoe on it. Now it won't lift the rear tires even with no implement on the back. It is not uncommon for the piston seals to roll/leak in these tractors. No intention of taking it to the dealer. I just need to find the time to figure out which cylinder is leaking, pull it and replace the seals.
If the frame or bucket doesn't drop I would suspect either the relief valve is bypassing too soon or the pump is leaking internally. To check relief valve again the ole pipe trick may work, or plumb in a pressure gauge. The same applies to the pump except two other "tests" does it lift better with the oil cold and/or does increasing the engine speed help?
