I have two identical HEALTHWAYS '62 SCUBA regs. Both are identical, however - one has a much better diaphragm that the other. When I try to put the better of the two diaphragms into the 'good' reg case, I cannot get the chrome cover clamp around the case as the diaphragm seems a tad thicker.
Is this a common scenario and what can I do about this - if anything?

Are you sure the thicker diaphragm is a Healthways? It may be another brand. Frans

Hmm, maybe. Looks IDENTICAL though - same color, same center material and color as well!
If it fits in the one case, why not the other case? BOTH cases appear identical!

"... one has a much better diaphragm that the other. When I try to put the better of the two diaphragms into the 'good' reg case, I cannot get the chrome cover clamp around the case as the diaphragm seems a tad thicker. It seems like you think that the thicker diaphragm is the better one. It might be otherwise. The thinner one should be more flexible. The more flexible the diaphragm is the easier breathing the regulator should be (if all else is equal). For that reason, and because you know that they fit that way, perhaps you should just leave each diaphagm in the case that it came in. That would also keep each regulator more in its original condition. The final answer to which diaphragm is better will come when you go underwater and try them both and see if one regulator breathes any different than the other. |

 Hmmm, I suppose I can try that! But no one else was selling Healthways diaphragm 'clones' - were they?

But no one else was selling Healthways diaphragm 'clones' - were they? That's hard to say. Your regulator is from about 1965. A lot of diaphragms were being made and sold at that time. Maybe Healthways had more than one supplier of diaphragms, and thus the slight difference. Maybe your regulator had a diaphragm replaced at a later date (say 1970) and the newer replacement was slightly different. Both of the diaphragms could be original Healthways and still be a little different from one another. Or one could be an after market generic replacement, if such a thing were available back then (too bad they aren't now). |

Hmmm, I see...makes sense!
But, wouldn't that mean that Reg #2's case must be 'deeper' at the lip to accommodate the thicker diaphragm then?
Thanks!

No. They probably had to squeeze the case 35-years ago when the one was assembled with the thicker diaphragm. But over the last three and a half decades the rubber molded itself to the shape of the case it was pressed into. Now you are trying to make it fit another case. The cases are very close, but not exactly the same as one another. It is similar to trying to swap used gaskets between machines. Maybe I'm wrong. I am theorizing without having seen the regulaors in question. |

Well,
now that I am finished replacing the exhaust valves, etc. I myself can't get the front and back of the cases to fit together tight enough to secure the case ring around the 2 cases. How is God's name did that original owner ever squeeze those 2 cases tight enough to do so is beyond me!
