Spare air regulator

[emoreira]

Hi people.
I've just bought in a garage sale a spare air bottle with regulator and filling yoke.
The previous owner told me that it was not working because it "could not keep air".
After revision at home I found out that some part are missing. In fact, the air inlet has not parts, so there is no valve to retain air.
I've been trying to find a diagram in the web with no luck.
Do es any one can post here a diagram of the regulator.
Thanks in advance.

Thanks for the diagram. Now I know what's missing.
Do you know where can I buy the check valve assembly ?

You might be better off throwing it in the trash and buying another one that still has all the parts.

Not sure what a working, used spare air goes for, but by the time you pay for parts and service, you probably could have bought another one.

my first thought was "why bother?".

but then i have no idea of your intended use. so the next questions are: do you have any idea of its capabilities? is it actually suitable for your intended use?

Spare Air Check Valve Assembly

It seems that the check valve is a spare part usually sold.

I do not get along with the idea of throwing and buying new. I feel better with the idea to repair what is repairable.

Another potential issue is hydro testing of the cylinder. In the US, only the old, small Spare Air cylinder is exempt from hydro test. The others require testing every 5 years. (Reference page 4 of the manual.) I have no idea what the regulations are in Argentina. Being a cautious person, and assuming you cannot know the history of the cylinder, I'd probably have it hydro tested before filling, no matter its age or size.

I've received the "Spare Air Check Valve Assembly", replaced it, and now the Spare Air works great.
Thanks to all.
