Another suggestion has been to match lunette and pintle as closely as possible.Been reading through the threads and I find the biggest complaint about a pintle setup is noise. I usually take a fat bicycle inner tube and cut it up into little sections and slip one or two onto the bottom jaw of my pintle hook. this seems to stop any clanking noise.
The inner tube does not last very long, but it is a disposable piece that you can carry lots of. if I am offroad I usually put [on] two or three layers. On the road one layer lasts quite a while. I usually electrical tape one end of it on, that way when it breaks up I am not littering rubber all over the place and the torn bits just hang off the tape so I can throw it in the garbage.
You can also wrap the inner tube and tape it around the lunette for the same effect.
I have had no binding issues or ill effects.
Probably both. Well matched and enough weight on the tongue to keep it from bouncing and banging.i have had the pintle for a few years now and maybe im doing somthing wrong, cuz i got no noise, it is very rare that i hear the pintle at all ,when on the road / highway i never hear it, when on the trail sometimes, and its not that loud,, is my hitch better matched ? or is my trailer loaded and balanced correctly ? cuz i swear i dont hear it very often,
I've got a copy of A-A-52550 which is the CID spec for the 18K, 40K and 100K pintle assembly hitches. Unfortunately, the inside diameter of the pintle is controlled by other specs, specifically international standardization agreement ASCC AIR STD 11/8, QSTAG 264, and STANAG 4101. This CID also states that these pintles as being interchangeable with MS51335F, MS51118F and MS51117E.The fit of the two parts is why I am interested in any published standards for lunette and pintle dimensions.
