Farmall H lift-all

i bought a Farmall H a couple years ago but never needed the hydraulics, but i am trying to set it up now just for the heck of it, any tips, and how is the best way to do it
 
Some people use threaded rod to pull it into place, I find it is quicker to put a floor jack under the tractor, set the pump on the jack and raise it up. It is much easier with a helper, but I usually am on my own. Just make sure you keep it straight as you go up and make sure you take the cap off the filler neck(I forgot that once and it does not fit through the hole). Once the pump is in place and bolted it is pretty self evident how the drive shaft and pipe nipples fit on. I have my control arm set so it is pointing at maybe about 1 or 2 oclock, it has four possible positions in which it can be bolted down but that one seems to be handy. The control rod should have the stop resting on the operator side of the holder-upper when the control is in the middle neutral position. I hope that all makes sense.

There are usually three outputs, all single acting. One is delayed slightly from the other two; it's used when you have a cultivator so the sides can lift first, then the rear.

It was designed have a line connected from an output to a single acting cylinder, the oil goes in to raise the implement and gravity lowers it and forces the oil back into the lift-all through the same line.

If you have a double acting cylinder you need to either vent the end you don't need or run a line from it back the top of reservoir (not to one of the outlets!).
 
The rear output has a delayed "drop" not lift.

If a delayed lift is wanted, a restrictor has to be installed externally in the line.
