The following was excerpted from two emails on 24 and 25 July 2014. Key Stage, Titan #31, is responding to a question by Jim Lanzaratta, Bodacious #44, concerning the rudder shaft's upper support bearing.
Dave Howell asked me to write re: your rudder shaft problem. I have not completely fixed mine, but I am sure we have a similar issue. I own Titan #31. Bob Allnutt with Victory had the same issue.
Take off the deck plate covering the shaft....you will see a square fitting that is supposed to receive the emergency tiller. Titan has the square portion of the rudder shaft INSIDE the round hole of the bearing....literally a square shaft inside a round fitting! My shaft groans as well in heavy seas with the auto pilot correcting course. Will try to find pics of my shaft....they were on my old phone and I lost them. Titan is 2 hrs. away but will take some more when I get down soon.
Bob Allnutt had the same issue. His fix , as will be mine, is to move the bearing down an inch or so to allow the bearing to be properly positioned on the round part of the shaft, not the square upper part.
Here are some pics of Bob Allnutt's showing how he measured a simple wooden block to go beneath the stringer to mount the bearing in a lower position, thus relieving the square portion of the rudder shaft in the round bearing.
