NRV broken !

I have a very good Primus 1S. I changed the NVR (I used a Fogas). It was working perfectly until the last time. I had a leak inside the pump. So I decided to screw the NVR a little more with my tool. Bad idea: the NVR broke inside the pump! Now impossible to disassemble the lower part. Very disappointed.

A extractor may work to remove the broken off piece, or desolder the pump tube.

@hikerduane Unfortunately I don't have the skills to unsolder the pump tube.

 

Two options, out or in!

Try using a Torx headed/sharp flat-blade (or similar) screwdriver to screw the remains of the brass cone out of the NRV body, you can then do similar to screw the body of the NRV into (or out of) the tank.
If everything is too tight you'll have to drill the cone out and use a screw extractor/screwdriver to remove the NRV body.

Good luck, the head is off so the locking device is off of the NRV, if you are lucky and nothing has galled/seized together, things will unscrew in a relatively straightforward manner....

Hi @Rangie thank you but I don’t really understand which kind of tool (screwdriver) you mention.

 

Any screwdriver sharp enough to bite in. It's only brass and you have nothing to lose.
Even sharpen/flat a piece of round bar, sacrifice an old screwdriver etc.

@Rangie Ok. I will try this. And As tou say I have nothing to lose. Thank you !

 

Mail it to BernieDawg? He does this kind of repair

 

@fjfj765 mailing from France to USA and back for a two pints is a little inconvenient.

I can easily fix that @Yannick Michel, if Italy is more convenient for you

How about this tool

 

I’d suggest start buying new items to save on not being able to make repairs.

@JP2 What kind of tool is this ??

 

Extractor. Do you have hardware stores where you live or automotive stores?
Duane

 

@hikerduane I have a nephew who is a mechanic. Maybe he has this tool.

 

Maybe higher a stove repair person, to keep on retainer, for any repairs to vintage stoves.
I'm sure there are plenty of vintage car owners incapable of car upkeep.

 

Here a example how it work

Have you got it out yet?

Alec.

 

No expert but having done both methods I think the desoldering of the tube is a lot easier in the long run.
