Got a good d14 full of oil,lifts really fast up to 900 lbs on the 3 point,but on any 1200 lb + bales,it comes up really fast to about 8 inches high and then cuts off pressure(wont lift no more)How do I adjust the pressure relief valve on a d14?Thanks for any help.

There is a speed screw, left side panel, under the gas tank, IIRR. I think the relief valve is on the pump, under, and in front of the PD clutch, again, if I recall right.

It sure dont need to be any faster.It sounds like you'd have to break it in two for an adjustment or replacement of relief valve?How much should it lift before kickout?

I suggest you beg borrow or rent a hydraulic flowmeter and guage, with a capacity of 5GPM @3500 PSI. Plug it into the remote, if it has one. Otherwise check the shop manual, for the test port location. Pump is a 4 piston type, runs on a cam, from the engine to the PD clutch. To pull pump is a no-split proposition, but if the cam lobes are wore off, you have to split it. There is no set weight, AFAIK, that it should lift. Pump should put out at least 4 GPM @ 3500 psi. You might have some debris on the suction screen, or a hinkey relief valve.
