Counterlung assembly

erikradstrom · July 14th, 2012, 10:28 PM

I promised in another thread that Ill take some pictures when I put my lungs back together. Why not put it in a new thread and maybe Matthew can use it in his Teardown thread.

If you make a full assembly like this, a tips is to not tighten the parts until everything is in place! It is easy to get the bladder twisted inside if you tighten it at one end directly. If you mount all parts its a bigger chance that the bladder is straight inside the cover.

I took pictures of the exhale lung were the OP valve is so all parts is included.

Here is all the parts

Always start with the MAV´s. The hole is the smallest so if you don´t start with it you will not be able to get the sealing and the threads inside the bladder.

All the MAV parts and how you put them togheter.

The nut goes in to the sealing and then inside the bladder threw the T-piece hole.

Push it in place and place half the bladder inside the cover so the holes align and then you screw the outer disk in by hand.

Next is the OPV

Mount it the same way as above threw the T-piece hole. There is a rubber disk that is supposed to go in before you attach the valve from the outside. Don´t forget that one!!!

Last is the t-piece, again same as above.

Remember the O-ring!!

Now all parts are mounted and tightened by hand.
Now I tighten all of them with the propper tools.

Hope this helps some one

If you are thinking of buying the T-piece and OPV tool, don´t by the plastic ones, they really are crappy! Narked at 90 sells the metal ones that are great! They will save you time and gray hairs!

That's great Erik, I'll add that to the article too along with the other updates I am working on! I'd better put a big credit to you too!

Cheers
Matt.

Good instructions. I was going to green you but have to spread love before I can give you some man love again!

Four comments:

1) Don't push the internal fittings through the small "inflator" holes, push them gently through the T-piece holes - otherwise, there is a BIG risk of ripping the material. Never push the fittings through the outer bag holes, only through the inner - as it stretches a bit.

2) Always ensure the outer bag fabric is at the very bottom of the thread, otherwise you'll get leaks. The tools we sell for tightening the T-pieces have a "chisel" end on the handle, which is good for pushing the fabric down. Alternatively, rotate the internal fitting anti-clockwise which will screw the fitting into the outer bag hole forcing the material to the very bottom of the thread.

3) do tighten the fittings fully using the proper tools. We see quite a few ham-fisted attempts gnarling the fittings up and still not getting them tight enough. The fitting tools we sell work well - RBTOOL6 is the one for the T piece. A.P.Diving Direct

4) if you can't get a 100% seal - i.e. completely leak proof when tested overnight - send it to the factory and we'll assemble it for you.
