Home Built European NRV removal tool

Built this this evening out of a 3/8" diameter bolt along with a couple of nuts and a lock washer with the OD taken down just a smidge to fit in the pump tube. I already have tools to remove Coleman check valves along with AGM and Akron. It's a little bit crude but it seems to work just fine.

 

Simple and effective. I like the spacer at the top to center the shaft.

 

Hi there!

What did you make the spacer of?

It is just a lock washer with the outside diameter ground down a little bit to fit the pump tube snuggly

 

That will do the job.

 

Very good! I built a nearly similar tool out of a square bar…so I can also drive it easily with a wrench

 

Gave it a test this evening on my Optimus 930 and it works a treat!

 

Well done!

 

Now I'll have to make one for myself! Excellent job.

 

Good solution

 

I could remember making one out of a T-handled socket wrench by cutting off the end and then grinding/filing that section to form a fitting slot.
It was used to remove the NRV on a Primus lantern.

 

My tool looks like this:



It’s easy to shape with a Dremel.

I see that most of us go through that stage and make their own NRV removal tools
My version made out of 16mm screw was posted there:

I lock the screw head it in the vice and turn the tank.

I have three. A commercial one with”enclosed” end found in a box of junk at a swap. Two homemade ones. One from 5/16 rod with a slot and a similar one but with the rod close to the diameter of the pump bore

 

Nothing beats a good old 'bodge'
Some of them work betterer than the commercial ones and are a lot cheaper.!
