| Post subject: | TILLER/RUDDER CAMS. |
I have just bought a 2nd hand hobie 16 and on my first sail I had trouble getting the rudders to lock down. On returning to shore I had a good look at the mechanism and my querie is How much vertical rotation can one expect from the rudder cams? do the y move at all? are they supposed to move? whats the best way to free them if they are supposed to move, and dont at the moment? I'm all ears. |

Review the sailing FAQ for details / cam information: http://www.hobiecat.com/community/viewtopic.php?f=18&t=467 |

Your cams may be stuck in the down (locked) position with your rudders unlocked. If not, they may be seized from disuse, especially if your boat was around salt water. The FAQ indicates how to unlock cams. Otherwise you will need to replace the cams and rebuild/restore the locking mechanism. There are cam kits and locking kits available for this. |

Yes, the cams are supposed to rotate through roughly 90 degrees. There are two positions- up and locked down. When in the locked down position, the "hook" portion of the cam engages either a roller pin or a flat plate in the upper rudder casting (depending on the age of the castings). The cams can get inadvertently placed into the locked down position even if the rudder isn't down, when this happens, you have to "pop" the cam back into the up position before you can lock the rudder down. To do this, raise the upper rudder casting up and out of the way. Then, place a flat object, like a large flat-blade screwdriver, between the bottom surface of the cam and the top of the plastic plunger (which is mostly inside the lower rudder casting) then pop the cam to the up postion. If your rudder cams constantly get stuck in the down position, either the rudder cam is worn out and needs to be replaced, the cam isn't properly lubricated, or the plunger spring force is too high (there is a large plastic screw on the under-side of the lower rudder casting that sets the plunger force). The cams are easy to replace. Just remove the pin that holds the cam in place (this comes from the factory as a large rivet that must be drilled out) and install the new cam using the sex-screws that come with the cam replacement kit (I recommend using loctite on the screws). A small amount of grease on the plunger and cam surface will keep the cams rotating smoothly. sm |
