Hi
Both turnbuckles on the inner shrouds on our JEANNEAU 53 are stuck - and I mean really stuck. My rigger has tried all types of oil including a torch etc. - but no luck.
There seems to be no other way than changing both of them. Upper part of the shrouds are ok but the turnbuckles are stuck at the lower part of the shrouds which are fixed to the chain plates.
I usually do most of the jobs on the boat myself but not really sure if this is a DIY job or I need professional assistance? Would I need any special tools or equipment?
Any help and/or guidance would be appreciated
Best regards Steen

Thanks Hoppy I have read that thread before but was not really sure if I could get away with cutting the turnbuckles. I guess it is worth giving it a try to avoid further work. Regards Steen

We had one stuck in Sicily and got a professional rigger to work on it. He got it unstuck but unfortunately we were not there when he did it. We went sight see and we had set a time for him to come and do it but he finished up other work first and came onboard and fixed it. He came back later and we went over the rigging and tensions and he said he had to use heat and it worked.

Hi, there. I have the same problem on my Jeanneau Attalia 32, but on one of the uppers. I was told the threaded part of the shroud is likely cold-welded to the turnbuckle, from stress. Soaking in diesel is suggested, but didn't to the trick for me. I was also told I had this problem only because both parts were the same material (stainless steel), so in future I'll try different turnbuckles.
I tried applying heat to the turnbuckle. Maybe I'll try again.
Anyway I'm happy to replace the entire shroud, which is pretty old anyway, but can't see how to detach it from the top of the mast, which is currently down. I think I'll open a separate thread for that one.
BTW my boat is on Lake Ontario and we take the mast down every year. Due to go back up in a few weeks.

Hmmmmm above are prime examples of lack of maintenance. Funny that people always are very careful about their engine maintenance and changing filters every 100 or 200 hours, yet never do this sort of thing.
Mark you perfect setting on the turnbuckles with tape (or count the threads exposed) and EVERY year untighten en tighten them, greasing them before tightening with some winch grease or similar. Part of the yearly maintenance of your boat. And if not....... you have the problems mentioned above. Same for your stainless bolts screwed into aluminium parts......every year, with a bit of grease, duralac or Tefgel.

I have been told, rightly or wrongly that the treads on the turn-buckles stretch and deform a little due to the years of upward pulling forces exerted on them . This and along with poor maintenance makes it almost impossible to move many years later.

New to forum. We have a 2006 Sun Odyssey 37 and when unstepping the mast our rigger had the same stuck turnbuckles. Gave him a fit and suggested replacing them. One of the inner ones was actually twosted. I want to replace them and am trying to identify the tread size for the 4 smaller ones as well as the 2 larger ones. Does anyone know the specs on these turnbuckles? Length, thread size, metric or otherwise?

You could try a homemade remedy. It’s the only thing that worked for me after trying all different types of penetrating oils, while trying to get screws out of my traveler a couple years ago. Mix up equal parts, say an ounce of each, of acetone and vegetable oil into a container with a lid.....shake it up and apply it to the turnbuckle and start working the part back and forth. Keep shaking, applying and working until it’s free

Does anyone know the specs on these turnbuckles? Length, thread size, metric or otherwise? I think the smaller ones are 3/8 inch and the large ones are 7/16. I replaced the one on the babystay which was bent, and that was definitely 3/8. I replaced it with a Selden turnbuckle: www.seldenmast.com/index.php?id=4489&setLang=enYou want the terminal/toggle type (but without the terminal). The Selden turnbuckles are slightly shorter than the originals, but it was OK for the babystay. Worst case, you may need to insert an extra toggle, like this: www.seldenmast.com/en/products/rigging_hardware/toggles/eye-fork.htmlMeasure the diameter of the threaded part to determine what size they are. If you measure with a metric caliper, convert to inches using Google. When tensioning the new turnbuckles, make sure to use the special grease that is intended for this purpose.

Thanks for the response. Very surprised these are not metric. Should I stay with chromed bronze or go with stainless steel?

Imperial threads are the worldwide standard for rigging turnbuckles, but you should verify what you have before you buy. Our SO37 is from 2000 and it is possible that they are different. Bring the old turnbuckles to a marine hardware store and compare.
Don't use stainless steel, there is a higher risk that they seize. The leading manufacturers switched from stainless to marine bronze many years ago for just this reason.
