That sounds very interesting--the new line you made. I may be interested in your old line, but I would like to know whether you cound make a new one, and if so how much it would cost. Replacing that check valve sounds like a good way to go too.

Hi
The check valve is a type that has a teflon seat with and o-ring, this way it can easly be rebuilt for penies. I tried other stainless steel check valves that contain a ball and spring, but they to eventually start to leak under load. This entire set up with new hose and fill block is about $129. I'll try and post a photo later on in the day for you to see.

The original drawings for the USD1 were done in 1973 so sorry for the delay!! The valve reg assy 1st stage part 1090-01 shows the "fat" oring for the modified piston as part number 1090-31. As far as I can recall in those days we purchaced all buna o-rings from Parker so the -31 should refer to the Parker size. We show 2 in stock!! I will size it up later.
The check valve in drawing 1090-03 Elbow Assy with Hose shows the face oring as 8201-12 (standard Scuba face) and two small seals on the filler swivel. This may be were you have been getting the leaks from as there are two differnt seals used. 8280-04 is a small white back up ring and 8200-04 is put on after as an o ring. The non return valve fitted inside the on/off valve was in 2 parts 1009-13 the valve core and 1090-47 the body adaptor. For replacement look up Shreider aircraft tyre parts. During production there were a number of engineering changes, Part 1090-47 adaptor mod was released in June 1974 (prior part was 1090-10) and 1000-13 core used to be part 1069-03. Again this could be the root cause of your leak problem.

iainhsm,
Thank you for the information. I would be interested in one of those O-rings.
Do you have access to the orginal drawings for the UDS-1 system, or any of the promational materials for it. I asked Aqualung (USD) about that, and they stated that this material had been lost to them in a fire in the 1980s. If you do have any original drawings, I would be interested in getting them if that was reasonable cost-wise.

John.
Re the fire at Santa Ana office, pity they lost there copies, but drawings sent to sub contract engineering companies are still around. However as the copyright is still with USD, one cannot make copies but there is no problem with sizes, parts or information.
The only other promational material I am aware of at the time 1974, were small gray embossed half size color catalougues. Front page had a hole in it with a color photo behind of the USD1. We did have 100,s but they may have been scrapped by now. I will have a original in archieve and will make a pdf of it if its the only one left we have and send with the o-ring. Email me with an address at iain@hsm-engineering.demon.co.uk and I will arrange for an o-ring to be sent out to you.

Hi Guys Thought maybe a few of you would like to see a photograph of the replacement Fill hose I use on a UDS systems. Ron

What is the USD system that you see Coustue diving with the double hoses ?

Hi
I'm not sure, I beleave there were several variations of diving cylinder packs specifially designed for the Cousteau dive team members through out Cousteaus life expeditions, This is a question for Mr rndboulder.

There were three versions of the Cousteau Housing. Ironically none of them were produced by US Divers. Both the UDS-1 and the ABS were developed by US Divers to capitalize on the Cousteau aesthetic. The first set developed for The Undersea World TV Series is best identified by its chest mounted regulator concealed by a breast plate. They were yellow and contained triple tanks made from the same alloy as the diving saucer. The second generation was developed by Technisub. It is called the RAID. See the link below. The RAID contained two 3000psi 72cf tanks. It had attachment for two regulators and a nice reserve mechanism. I just finished restoring one. The third was a set of four 5000psi tanks in a very slim housing. I am working on a museum for my website that will feature information and photos of all of the Cousteau tank systems as well as other Cousteau equipment from my collection and others. It will be a little bit but it is in the works. I have an updated diveable version of the RAID available at www.flashbackscuba.com I am working on updates with other products that will be available soon. -Ryan vintagescuba.proboards2.com/index.cgi?board=buysell&action=display&n=1&thread=1395

Hi
Darn thing, I've been setting up my DSV unit today, we took the regulator broke it down cleaned her up and replaced the Hp seat. Now, when the system is charged and we try to ajust the iP pressure for the regulator it begins to leak around the piston o-ring. This o-ring is a pain in the rear as they tends to all leak or at least all the DSV units I've seen in my life have this leaking o-ring or is it something I'm doing. Any advice is helpful and even prayers accepted at this point. This 0-ring is a difficult one to mach up, even at the o-ring supply shop, it seems the out side dimensions are obtainable but the inside hole is not standard and not even listed.

Ryan, on the first Cousteau system, what regulator was used under the breast plate and do you know how they got the air to it? Hp or Lp hose?
Thanks
John

Your not talking about the UDS unit are you, no breats plate there.

The reg was a Mistral. I do not know for sure at this point if it was fed by LP or HP. It was suggested to me that it was LP. I have just worked out a deal for one of those housings w/ tanks, and I am going to meet with the person who originally assembled the units. I will be making replica housings with molds made from the originals as part of the restoration process. They should be very cool. There were only 16-20 units ever made. I should have answers in the next couple of weeks. I am setting up meeting with several people in CA that were involved with the production of the Cousteau equipment. I should have a lot of new information in the near future. It looks like I will be doing a presentation at the Wazee get together. I should have a fairly large selection of original equipment for display. Stay tuned. -Ryan

Hi SeaRat
By chance do you or any one on this board have a copy of the manifold service data for the UDS system.
Thanks
Ron
