Regulator Washers Configuration
While I wait for Ed to ship me my replacement breech I going to strip the regulator down on my R3M and give it a clean and polish, before I do can anyone tell me the configuation the washers in the regulator should be as their bound to fall out as I take it all apart, are they like this or something different:
()()()()()
and whats the best lubricant to use in the regulator?
Cheers

Thanks Hemn and Wanta edgun for your assistance I got the washes out easy enough and ‘ll lube with a light touch of moly.,
I came across a post by ernest who gave the washers a polish so ive done the same, I dont know what difference it will make but we’ll see when I put it all back together.
I’m going to fit a depinger to it as well whilst everything is stripped down.
What started all of this is the rifle has lost its accuracy for some reason , the JSB pellets shoot all over the place thats when I first changed the seal in the barrel after cleaning the barre and checking screw tightnessl didnt solve it.
So I’ve still got a couple of questions,
I’m thinking of changing all the seals in the regulator for polyurathane – is this a good idea? Or should I stick with the nitrile ones?
Is there anything elseI should do whilest I’ve got it stripped down?
You’d better do…
Ok, So, you recommend me to disassemble the gun and re-lube the washers with above shown moly grease???? because i put a silicon grease on the washers when i re-set he regulator recently ,,,
In the spring chamber of the regulator normal atmosphere pressure.
Eduard, thanks a lot for correcting my mistake,,, but never expected to use a Moly grease inside a PCP rifles especially inside the regulators with such a high pressure,,, please don’t tell me that i have to disassemble my edgun again and re-lube your Regulator that i lubricated with silicon grease :biggrinn: :biggrinn: :biggrinn: :biggrinn: :biggrinn: ,,, i have below Air Venturi Moly Metal-to-Metal Paste, ,, so tell me can i use this on the washers????
No silicone grease on the metal parts! Never do it, otherwise you will find out soon that there will be a kind of glue instead of lubrication. Silicone ONLY for O-rings!
I was actually surprised to see that Ernest used a little bit of Molly on the spring washers. Since I realized that the spring washers are actually vented to atmosphere, they aren’t exposed to the unregulated pressure side or the regulated side. I don’t like using silicone an anything that is metal to metal. I do from time to time but only if its high pressure or something that I am Likely to come in contact with. I.E. the cocking bolt. And that’s only cause moly grease is a horrible thing to get on your hands. Cause it then gets on your cloths, face, wife’s couch, kids, pets, sex toys, crime scenes, evidence, warrants, ect…..
Brother Marc…
the best lubrication is a silicon grease and you shouldn’t use anything except silicon grease on PCP air rifles,,,
the shape of the washers just like how it shown in below pic,,, this is my Edgun regulator ,,,,and yes,,, they are just set how you mentioned,,,

Do you have any proof that the reg is causing the accuracy issue? In example, crazy Chrony results or shot groups that show mostly vertical deviations? Normaly I wouldn’t start with the regulator as the first suspect unless there is a history of it being an issue or it only starting misbehaving after I had the reg apart.
I’m no expert on the edgun but I would start by checking that the barrle shroud isn’t touching anything. I know there have been a few people that have found the barrle wasn’t positioned properly after they removed the stock. This is because the stock helps to push the bottom of the front clamp into the air cylinder, which pushes the barrle upwards and away from everything else.
If I was you, I would get the grease repalced and put everything back together in original configuration for now and work on the accuracy issue. Even if the reg is the problem, you don’t want it modified for now. I don’t know Eds policy, but I wouldn’t warranty anything that had been modified. When Ernest is working a reg, I think he is doing everything he can to give his customers as much as he can for what he charges them. He is “blueprinting” or hotroding them. Plus he knows what he is doing. I don’t think that polishing the spring washers is realy going to do that much for you right now. The edgun regulator is considered the best (or one of them) in the industry, if it really needed to be polished to perform well, it would have been done before it was built. Polishing a bunch od washers at a factory is simple and cheap. You just throw them in a giant vibrating bucket with the right Media and like magic, you have 1000 regulators worth of washers polished. Simple in mass production, a major pain in the ass for one guy doing one reg.
If there is something wrong with the reg you need to give Ed the chance to make it right and also get the bad parts back so he can see what went wrong. I once worked for a company there %90 of our mufflers were defective, but we never knew it cause everyone pulled them off and replaced them with louder pipes. When we broke stuff in testing, it was blamed on the duty cycle and written off. A few years later when they decided loud pipes were a bad thing for the industry, we were screwed. Because we never got any feedback from the customers and never got any failed parts back from the dealers. We weren’t ready for the mass failure rate coming. We actually had to give everyone the same pipes we didn’t want them using anymore for free. So the only thing that changed was that we were paying for all of them. Well, that’s a littl off track.
If your having accuracy isues I wouldn’t modify anyting until you know what’s wrong. Your more likely to cause a second issue and never know if you got the first issue taken care of.
