      Sorry, it is not the same as mine.  Look very closely at the pinion assembly and you will see the difference.  I've taken mine apart several times and it is exactly like my picture.  Joe your picture is slightly different.  This is the problem.  Lewmar doesn't have the older drawings of systems before they bought Whitlock.  Somebody at Lewmar sent me the correct drawing but no one there knows its identity.

        Florida Rigging and Hydraulics is one of Lewmar's Master Parts Distributors. I agree with Bernie, they are very good. I recently ordered a fitting kit for the throttle control mechanism from them (on page 178 of their parts catalogue). The draglinks and rod ends are on page 190 of their catalogue. 

        Best,

          When I called Lewmar for support with my throttle control problem this past spring, they told me that they didn't currently have an expert on these steering systems. The support guy at Teleflex was able to identify what I needed. In my searching, I couldn't find any better diagrams of the steering system.

          Sorry, it is not the same as mine.  Look very closely at the pinion assembly and you will see the difference.  I've taken mine apart several times and it is exactly like my picture.  Joe your picture is slightly different.  This is the problem.  Lewmar doesn't have the older drawings of systems before they bought Whitlock.  Somebody at Lewmar sent me the correct drawing but no one there knows its identity.

              I have replace the Rod end bearing and now understand the failure mechanism. It appears that the quadrant had sliped down the rudder shaft about 1 inch. As the rudder is turned hard to port the draglink would hit the bottom of the opening in the aft cabin bulkhead as the rudder was put to the stop the pin was about 1/2 inch lower that it should have been applying a major upward force on the bearing assembly.

              Those attachment points are so robust it is hard to fathom how one could break.  If the were so misaligned I would think it would be all but impossible to even steer.  Make sure stops are installed on the system to keep the rudder from going too far to either side.  If a stop is missing I could see the rudder turning beyond the limit of the drag link.  If a stop is missing it is usually because of the rudder slamming over while in reverse and breaking the stop.

                Glad you found the cause.  It is a good idea to get down in the aft locker space and watch the movement of the tiller arm and drag link from hard over to hard over to make sure everything is moving freely.  You might even try fitting the stud on the top or bottom of the tiller arm to allow movement with no binding. 
                If you change the stud position you will also have to move the tiller arm up or down.
                It could be someone changed the stud position but never compensated for it by moving the tiller arm up or down
