Replacing Navtec Turnbuckle screws

[newportknots]

Has anyone ever replaced their turnbuckle screws? I've looked around quite a bit for a tutorial but haven't had any luck. Anyone got any tips or advice on doing this job right?

Why do you believe they need replacement?

As to your question: Assuming they're C500, C600 or similar: Unscrew the old and screw in the new? Am I missing something?

Yes, they are C500s.

Maybe I'm making this harder than it should be. Is it as simple as sticking a screw driver in the turn buckle and unscrewing?

I am not seeing this the UNIT is good or bad ,any dammage on the male threads would cause and issue on the female threads


The big issue on my navtec parts was the pressed in pins on some ends had gotten lose and were ready to fall out

Well, Navtecs are "backwards" compared to most common turnbuckles, in that, instead of two screws coupled by a body in the middle, they're two "bodies" coupled by one screw in the middle, but, essentially: Yes.

Of course: If your rig is actually, you know... up, you have to do this in such a manner that you don't bring your rig down in the process .

Again: Why do you believe your Navtec screws need replacing?

Btw: I use Forespar Lanocote on the threads.

Yep, rig is up. One at a time of course.

They are beginning to shows signs of corrosion.

Rigging Matters: Navtec Discusses the Importance of Inspecting Rigging

One item that Navtec does recommend replacing after 10 years of use or 40,000 miles (whichever comes first) is the turnbuckle screws. With the stress concentrations due to the threads, cracks could be forming that may not be noticed until they fail. The screws may last for many additional years, but it is much cheaper to replace a few rigging screws than to replace a mast and all of the rigging.Contact Navtec for further information.

I found many disturbing lose pins on my Navtec parts at the red allow which could have fallen out and IMHP if the threaded rods are bad the wire must be getting tired

Thanks Guys. I had the rig inspected last season and he thought the rod was OK.

Catamount - are those your cottages in Boothbay? I'm up in East Boothbay for part of the Summer every year. Leaving Friday actually.

On Zzzoom a C&C 35 the rod looked fine at 20 years BUT the only way I have seen is to cut the rod and reform the heads

On Zzzoom the rod would not take new heads as it had become to hard and was replaced
