I had my boom cylinders repaired (new rods and a barrel I bent them) and failed to note how the lines were removed. But I am not sure it matters. When the ends of the rods are disconnected from the top of boom, the rods are pushed out no matter what direction I call for. When I replaced them last year I had them going in {i]opposite[/i] directions at one point! Let me just ask it this way. When both cylinders are pinned at the back end, with all the hoses hooked up *properly*, but both working ends of the cylinders are not yet pinned to the top of the boom, should the rods obey the inputs just as if they were pinned? Do they behave differently in any combination? Of course, my thought was that they shoul dboth operate in the same direction as the input calls for, and operate in the same direction simultaneously. But I can't get them to do that no matter what combination I use to hook the hoses up. And I can't tell from the "lay" of the hoses, you know, how they hang from the memory built into the rubber from how they were hooked up so long, because they are so close together on each boom you really cant tell how they were hooked up.
