Hello all, OK, I think I have a weird thing going here... I have adjusted the wheel to center the turks head knot straight up when the wheel is centered. I got it all nice & straight a few weeks ago, and came back to the boat to find it about 20 degrees off to port. By the way, were talking about 20% off on the wheel, not 20% of rudder. After installing my autopilot, I again adjusted it, this time getting the cables set to approximately the same amount of adjustment on each side to the adjustment bolts through the radial drive wheel. This required jumping the chain 1 or 2 notches on the wheel sprocket. All was well for a couple weeks, and behold, on Saturday I went back only to find the turks head knot about 20 degrees to starboard. During these adjustments, I have made a point to keep the cable deflection adjusted to be relatively minimal (say 1/2" or so?), without getting so tight as to reduce the feel of the wheel. I've notice no issues whatsoever when we're out sailing.
During the first set of adjustments, I noticed the idler wheel bolts were a little loose, and tightened those. Considering the radial wheel bolts connect to each end of the cable, and the cables attach to the chain, I can only think the chain is somehow jumping on the sprocket. Thoughts?
