I got an EDMU with a leak. Anyone here has this tool to replace a leaking o-ring.

I bought a used Leishy, previous owner put a dab of nail polish where to touch sensor to get a reading. It read pressure once in a while. Gun developed a leak, and I replaced everything starting with that POS gauge. Why put something with the possibility of a leaking O ring, failure of the sensor, and guaranteed replacement of the battery on one of the most reliable guns made. I'd be curious as to how many would opt out if a choice was offered with the original Wika and by pass that digital nightmare.

I like std gage better , when they first came out it was fun t see numbers but seriously , I had problems with mine and Brain converted my guns to Wicca . I mean after you know gun you know shot count and stuff , while it is great idea of EDs I like the ruggedness of WICCA to be on my edguns., I never had tool , last one I tried to swap oring a wire fell off , I didnt have good luck servicing them .

After using one on my Leshiy and having problems with this same gauge I am of the firm belief it isn’t worth the hassle of dead batteries and leaks. Less than a year old my Edgun sits in a box because of a broken gauge. I will be swapping out the gauge after the holidays once funds free up.

I’m a fan of the EDMU, I’m a gadget person and to me the EDMU is another gadget for my airguns. I had 3 Leshiy with EDMU without any issues. This EDMU with on the video was going to be installed on my Impact MK2. I tested it before replacing my MK2 gauge and realized it was leaking. I’m just trying to find that tool to replace the o-ring.

I got one of these but haven’t tried it yet with the EDMU.

I have the same tool. It won’t work with the EDMU. The space between the widest indent is about 18mm and one indent is about 1.9mm.

Unscrew the ring with small needle nose pliers or straight snap ring pliers.

I wish that the tool came with every EDgun purchase or if Brian would sell it separately on his site. Maybe a machinist could get the specs and start making them for us.

 

[Centercut]

Good idea. Unfortunately Brian doesn’t have one and Ed doesn’t sell them. Maybe someday...

Heavy, maybe the Mountain from Game of Thrones could do it with a needle nose but regular humans, not so much.

Problem solved! Made a DIY tool with one of these. 

I file down the tip of the pins to about 1.8mm diameter and place the EDMU on a vise and use the pin wench to unscrew the senior out and replaced the o-ring. My EDMU is not blowing bubbles anymore. 

Here is what my DIY tool looks like. 

I had to file down part of the base of the pin wench cause the pins was only 8mm long and It needed be be about 9.5mm to reach the senior ring. 


Hope this information help others with a leaking EDMU.
