Re: Tensioning my steering cables.
in photos it looks like a cable has jumped out of the top groove in quadrant and riding with the bottom cable. 1 cable is ran higher than the other and run acrost back of quadrent to the adjusters 1 cable in each groove upper and lower. If 1 jumps steering can bind and cables get loose I just fixed a 1986 Grand Banks trawler a couple days ago with same problem but his were so loose 1 cable would come off when he backed into a mudbank. after reruning cables into there proper groove I had plenty of adjustment to tighten them up.

Re: Tensioning my steering cables.
Just a note on the stainless chain. Mine broke while sailing into anchorage. Caused a little excitement but no damage. I replaced with motorcycle chain which is carbon steel vs stainless. Its well greased so corrosion is not a problem and less suceptible to stress corrosion

Re: Tensioning my steering cables.
No noticeable effect.the compass is about 8 inches above the sprocket. I don't know what the magnetic field is of the stainless but I have circumnavigated with the steel chain

FWIW you can buy stainless steel chain from sources other than Edson for far less money. |

Personally, I’d look for the CAUSE of the problem before kludging such a “cheap easy and fast” solution. Anything else is an invitation to steering failure. If I was looking at a boat with that kind of maintenance I’d stay well clear. |

Possible that there is nothing wrong with the system other than the inability to tune out some slop Cables stretch over time. It’s possible that when the new cables were installed they were cut a smidge too long, or the hooks were not returned to their full loose position When the new cables were made or a combination of the two. Looks like the op has done due diligence at least in looking for possible areas that could create the slop and found none. Cables look clean, hooks look old and grungy, quadrant could use a scrub, Meh.... new hooks washers and nuts and a good cleaning. Snug it all back up, cast off the lines and go sailing. It’s rare on a boat, but sometimes, the easiest and cheapest fix, much to the chagrin of chandlers and boatyards, is the right fix. |
Re: Tensioning my steering cables.
Imho, 10 years is a long time. The cables need replaced, regardless of grease or appearance. The steel will fatigue and fail without warning or signs of wear. Likely other stuff needs replacement as well. Edson has a guide to inspection and rebuilding, and drawings of factory installs with parts lists.
Do not attempt to remove a link from the chain. You could try removing the crimped loop on the end of the cable and replace with clamps. A new cable from Edson will use clamps. |

Ten years is old, particularly for some of the rubbish wire on the market. Whatever, the OP has a number of suggestions here, they can choose. Myself, I think steering systems are too critical for shortcuts. |
Re: Tensioning my steering cables.
I have no experience with the push/pull system noted here (sounds like a nightmare idea of manufacturers to reduce their costs of production that will be a headache for future owners), but have worked numerous times on the traditional pulley/cable systems on the several boats I have personally refitted. I would urge caution with some of the advice in this thread. Chain breaking before the cable?? Really?? I suppose it is possible in the worst of all possible worlds but it is difficult to imagine that is basically a motorcycle chain that turns a very short arc. In the normal cable/pulley arrangement there is a great opportunity for failure of basic maintenance and sloppy steering as a result. The cables will stretch under normal use and this is what the bolt and nut arrangement at the cable ends on the quadrant are there for. Edson provides instructions for how to tension this, but it needs to be tight, but not bar tight. I suppose they will sell you a chain but the maintenance Kit I have bought from them a couple times is just the cable and that is all that is needed. I usually replace the brake pad at that same tiime (use a cloth so you do not lose the parts in the binnacle when servicing the brake--it is a pisser of a job the first time you do it).
Here are the failures of boatowners: 1. Failure to lubricate the pulleys and cable annually. The cable will stretch under normal usage, but it really is going to go fast if you do not put some oil on all the cable and turning blocks. Watch out for meat hooks on the cable. These are not necessarily indications of the need for immediate cable replacement, but meathooks should not be numerous or concentrated. The instructions for the cable replacement are clear and simple--read and follow them. 2. Failure to lock the steering with the brake when on the mooring or in the slip. The action of wave and current pressure on the rudder will be acting and moving the cable and pulleys even though you may not see it. Wear and shock on the system from this motion transfers loads to the cable and pulleys that stretches the cable prematurely and wears out the pulleys--even if they are all lubricated and attended properly, which my guess is rare from what I have seen in the boatyards where I have worked. Seems to me that this is one of the greatest maintenance failures on most boats. Seems to me that folks spend way too much time putting the latest gee gaws on their boats and frightfully not enough attention to basic maintainence of systems like this (and the cooling/exhaust sytems). Just one opinion. I am sure there are others. |
Re: Tensioning my steering cables.
it's not so unreal....I've had a chain break...never had a cable break...

Re: Tensioning my steering cables.
I know of two Leopard catamarans who have had the chain break. It looked like a crevice started on one of the cheek plates on a link.
Our Leopard 40 cat has the Edson steering system that includes a length of conduit, which we found had corroded. We then found broken strands in the wire. We replaced both cable and conduit. The sheaves were fine. We were told that the lifetime of their systems is 15 years. The chain didn't show any cracks, but we replaced it anyway since the lifetime of such systems is based on the number of stress cycles. Our system replacement is described here: https://svlux.blogspot.com/2021/01/s...ng-system.html |
