How to inspect Norseman terminals

[Sonrisa]

Hello,


My rig has Norseman swageless terminals, and I have the original brochure which says they can be taken apart for inspection of the internals at any time.


But I've read elsewhere that new cones are required when re-rigging. I'm wondering if I can take apart for inspection without replacing cones. Does anyone have experience with this process?


Advice appreciated, thanks for your time.

If your money furnace wants new cones, then you have no alternative, install new cones after every inspection.

Its the kind of part where the labor to open, inspect, clean, reassemble is most of the expense, even if you do it yourself. Your time is valuable too.

I do not believe that simply separating the two halves and inspecting the internals requires replacing the cones... if you do not remove the cone from the wire (a difficult job without damaging things). And FWIW, I've never found any defects and no longer worry about routine inspection .

I have done this multiple times over the years with both Norseman and StaLoc fittings, and no ill effects.

I had sta-loks on my last boat and norsemans on my new boat.

I replaced all my standing rigging when I got my current boat, and inspected and re-used almost all of the Norseman fittings that were on the boat with a few exceptions (below). None of them had any signs of corrosion, galling, or other deformities.

The issues I did find were that some of them were probably over-tightened a little, and the wire had left a grove on the inside of the fitting. They were probably fine.

Any issues you have will be with the wire inside the fitting, not the fitting itself.

There might be a cheaper source.

As Jim said, cones do not need to be replaced if all you are doing is unscrewing the fitting for inspection. Like Jim, I gave up inspections after many years of cruising with both Norseman and Staylocs. I did use a neutral cure silicone sealant when assembling both types.

I know Norseman etc have said you need to replace cones if you re-rig but plenty of people (including some riggers) will reuse them if they are undamaged.
Certainly if you are just inspecting, changing the cones would do more harm than good, as it would require extra stress/bending etc on the wire rope
