    Hmmmm?

    OK, the original question was, "What is the old goat up to"? Incidentally, note the close resemblance. Here he is, holding the FINAL PRODUCT !!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    Hmmmm?

    I'm mulling the choices: good back slap, carrot award (for smarts) or a bust.

    Hmmmm?

    Sculptor, good guess. indeed things will be "hinging" (moving) around the combination of the tube, the internal shaft and the other parts. There are other parts in the picture, parts of the "thing", particularly the big plate

    Hmmmm?

    I see you guys need more clues. As far as chopsticks are concerned I'm working with Benny, my Miniature Pinscher on proper chopsticks and sushi etiquette.

    Hmmmm?

    Nah! that's too minimal and cruel for good guesses, just a tiny additional clue. Going out to a jazz jam session so there will not any additional clues for a few hours, but I expect lots of "interesting" guesses when I come back.

    Hmmmm?

    The old goat, has been keeping a real low profile lately, but he's up to his old trick again! What the hell is he up to again, let the guessing begin??????????????

    Air Hitch leveling valve?

    As an engineer I should have known to be more precise and should have said "several thousands pounds of FORCE" It's a fact that the air molecules, oxygen, nitrogen and their lesser cousins are an unfriendly bunch that hate confinement, sort of like folks who hate cities and have to move out to their acre size house lots in suburbs. If you force more of them to live together into a confined space (an air bag), they get very bitchy and start elbowing each other big times, hence the force proportional to the pressure. That's my best description without getting into Boyle's law, Charles' law, etc.

    Air Hitch leveling valve?

    Rich, I have the info and I've modified few ETs so that its airbags can be dumped and thus provide additional 3 inches of clearance for anything that needs to go over the hitch. But such as yours it is not a common requirement, most things are loaded from the side. Orca, your approach is the correct way to unhitch an air hitch without a leveling valve. When I designed an ET I thought that the hitch could work simultaneously and in the same manner as the truck suspension and require no adjustments regardless of the pin weight or cargo loading. After all, truckers don't have to fool around with the suspension, they hitch up whatever they have to hitch up to and go. An air hitch will have several thousands pounds of pressure in the air bags while operating (the pin weight), bad things happen if you drive off with all that pressure still in the air bags.

    Air Hitch leveling valve?

    Orca, good question and fair question. ET hitches have leveling valve and were designed with one from day one (10 years ago). This has created two classes of people, "dumpers" and "non-dumpers", the non-dumpers being the ET owners. I have to spend considerable time with new ET owners to undo the dumper instincts, they are "powerful". Unfortunately there is no patch to deal with that addiction. The non-dumper technique is pretty simple and "gentle" on the truck and trailer. When positioned and ready to unhitch lower the fifth's jacks until they come in firm contact with the ground. Lower the jacks (raise the fifth) a little more (1/4 inch or so) and listen to air hissing. The sources of that high pressurized air are twofold, the hitch suspension (air bags) and the truck suspension (air bags), after a minute or two the hissing will stop. Raise the fifth another 1/4 inch and listen to the hissing air again, you might have to do it 2-3 times until the last time you raise the fifth you will hear no hissing and you will observe the the king plate has slightly separated itself from the top of the hitch head (there is a slight gap). Open the jaws on the head and drive off☺️ You have just joined the ranks of "non-dumpers" The whole concept involved here is this. By slightly raising the fifth you are removing the weight from both, the hitch and the truck, therefore both dump the air (automatically) to reach the "new" equilibrium (in the hitch and on the truck). By repeating this you eventually reach the point where there is no weight (from the fifth) on both the hitch and the truck. At that point there still will pressurized air in the hitch and in the truck but only enough to keep the truck and hitch level and not supporting the fifth any more. Therefore nothing will "jump up" when you drive off. In my earlier post I mentioned the design of the bracket which you need to hold and position the valve, you see one holding the air valve in the above picture. Its height and location is not arbitrary for the system to work properly, quite a bit of thought went into this simple bracket.

    Air Hitch leveling valve?

    Either valve in Jim's posts will work, but you have to work out the bracket to position the valve in proper location and height to bring the hitch to the working height. I purchase mine from Volvo and they come with mounting plate and additional hardware.
