Told them which zerk it was and why I wanted to replace it. They never mentioned anything about it being by design. I eventually tapped it out and put another zerk in there with a check valve.
Also changed steering cable and cleaned out that tube. Haven't had any trouble. When I grease it I wipe everything down several times as I move the rudder back and forth slowly to ease excess grease out. My steering is actually very nice but of course now I'll be aware of it and MCOCD will begin to eat the brain. Guess if it comes to it I can pop the bearing out of the valve.
I suspect that the check ball is omitted to prevent and pressure from affecting steering effort with either negative or positive feedback. Probably only encounter that when overfilled with grease, but I know what my MCOCD would have me doing.
