I have a bypass valve in the system which allows the wheel to be "disconnected" from the system and the ram can then move freely with the hydraulic fluid just moving from one side of the ram to the other without going through the pump. This was added to allow the use of an emergency tiller if the pump, drive chain, or wheel failed. The ram itself can rotate 360 degrees at any position setting, which I assume is proper since it needs to thread into the swivel fitting. The lock nut is supposed to prevent it from unscrewing itself, but I guess the original installation either wasn't done correctly, or it worked loose over time.
The Engineer who designed the system finally called me back after 2 weeks and went down to the boat to inspect the setup, and my fix, and checked to make sure the lock nut was properly tightened. He was very surprised as well that it unscrewed itself, and apparently this was the first time one of his hydraulic installations did that. I will ask him about adding a pin to prevent it from backing out in the future.
