Voit Navy Cyclone and HPR update parts?

Fri Jan 12, 2018 6:10 pm

Just wondering if I could clarify with some of the DH specialists here what parts I need to overhaul and update a Voit Navy please?

I'm very much still feeling my way along the interesting DH restoration path and have spent hours combing the Forum and Webstore.
SO... if you can bear with me as I ask what are probably pretty basic questions...!

I'd like to update it with a Cyclone and HPR, plus a new silicon diaphragm... these parts are straightforward and in-store.

Where I'm getting a little confused is what other parts I require to overhaul the rest of the regulator given the above new components, and NOT to just overhaul an original unbalanced Voit Navy.

So I <think> I need the following additional parts, (apart from new hoses, mouthpiece and updated umbrella valves)
HP diaphragm:

Voit Two Stage Overhaul Kit:

I have some service tools arriving from Herman soon... any other parts suggestions gratefully received :)

If you are installing a Cyclone and a HPR along with a new LP diaphragm you are going to need a few more parts. Using the Voit 66 exploded view, part numbers 4, 10 ,11 and 12. All are gaskets. You have 2 options, order them separately (not sure Bryan sells them all separately) or just get the DA/Navy kit which contains all of them. Granted you will have a few spare parts but I like to have them around, one of the springs will work in the HPR and the screws are nice to have.....if screws down under are the like the ones here, they actively seek out holes to hide in.

In addition to the parts above and those you have listed, you will also need a duckbill or a duckbill eliminator (DBE) . I much prefer the DBE to the duckbill. It works better IMO and allows you to remove the hoses without the problems dealing with the duckbill. I would also suggest a band clamp as opposed to the box clips. They make the reg easy to get apart which encourages you to open the cans for cleaning and inspection.

Are you going to need/want to use a SPG and/or any LP item like an octo? If so, then you may want to consider ordering a banjo for the SPG and a LP port adapter. I recommend the LP port adapter reguardless since it can be used to connect an IP gauge to the reg using standard IP gauges. If you want to use the banjo, your reg will also need a long yoke. Some later USD regs had them, I don't know about Voits but a USD long yoke will work.

If you intend to dive this reg a lot and use it on commercial dive ops, you might want to consider a Phoenix instead of the Cyclone. It gives you the option of diving old school with no HP or LP ports (just block them) or adding any modern feature you want or may need to keep the dive ops happy. I am pretty sure I saw they were back in stock.

I am in the shop most of the day today so your tools should be ready to ship on Monday.

Hope that helps, don't hesitate to ask anything you have questions on, we are here to help, no need to go it alone.

Hi Herman

Many thanks for your detailed response it helped me a great deal.
And yes, small springs and screws behave exactly the same downunder... seeking the furthest recesses of my workship to hide :lol:
Just trying to anticipate ALL of what I need as the exchange rate plus shipping to Australia means $$$ and much lost time if I miss something and need to re-order!

One of the reasons I ordered a Kraken first was that dive boat operators will refuse to allow you to dive if your equipment does not have a BCD inflator, SPG and octo reg prominently displayed. As the characteristics of DH diving are quite different, and I am still learning I didn't want to be the obvious DH newbie complete with a 1960's era reg!

Even so while they are all fascinated by the Kraken they remain somewhat dubious, but the uber-cool logo and obviously modern design wins them over. Particularly when I surface alive :shock:

It will be interesting to see their conniptions when I turn up with my Spiro Royal Mistral mounted to an H valve + Atomic Z2 DIN carrying all the ancillaries!
