Modified rudder top bearing plate.
Due to a banging noise from rudder on my Cruiser 40 2008 twin wheels. The upper rudder bearing aluminium plate slip sideways due to the elongate holes. The two stop screws are not efficient when movements came from rudder (when load was reversed on the rudder.), I changed these two Parker little screws with through 6 mm bolts and nuts. Also I add up an down two big aluminum custom washers 8 mm thickness, bolted whith six 6 mm bolts ad nut. All side movements are now impossible. I also changed the two bearings with new Jefa roller bearings and adjusted chains tension not too loose not too tight. Now sensibility and lightness windward are excellent.
