Looking at the service diagram, I'm assuming that the end of the cylinder rod which has the zerk in it is facing down rather than up?
That should be able to be remedied by raising and blocking the boom, pulling the pin and lowering the rod end enough to get a bar in and turn it 180 degrees so the zerk is facing up, then put it back together.
If it's pocketed in so it won't drop down, it should be able to be retracted by slowly and carefully lowering the boom control, which would retract the unattached cylinder only, as they are in parallel. Then carefully ease it back into position once it's rotated.
Of course since it was a dealer cock up, they should make it right, it just depends on how much hassle it is to load and transport (and distance) for a 15-20 minute project.
