The upper ends of the cylinders are probably being used for auxiliary reservoirs. A belly pump doesn't hold enough oil to raise most one-way loaders all the way up without going dry.

This was VERY common with those old "straight arm" loaders with the really long cylinders.

As the loader is raised, oil is pushed out of the tops of the cylinders and into the belly pump through the fill pipe. When the loader is lowered, the excess oil is sucked back into the tops of the cylinders.

Tom B:

You do NOT want the return line on the bottom of the sump. Leave it where it is. Otherwise, the belly pump reservoir will never be full. Here's why:

Because the cylinder shafts are taking up some room inside the tops of the cylinders, there will never be as much oil coming in as going out as you raise the loader. If you raise the loader and refill the reservoir, the loader won't go all the way back down for the same reason.
