Finally after nearly 4yrs i took my reg out 😂 my 11 washers are stacked the same a part from the last one, that is stacked the same as number 10 😁 never had a leak or reg creep or serviced it, but felt it needed a change
Thank you Newman! I have a very early Crown mk1 in .22 and your video really saved the day! I has serious reg creep and those two tiny orings on the adjuster screw where it! It's back in the game! One thing was odd, I had twice as many spring washers in mine, arranged as pairs, so two up, two down, etc. Have you ever seen that?
Likely you have a pre-AMP regulator, which typically came with 16 washers rather than 11. If the washers were thin, more may have been needed. Glad the video helped!
Excellent information. It would have been much helpful if you have printed the O rings information ie dimensions and type to snapshots a reference for your followers. Nevertheless. A valuable piece of work. Thanks for your time and effort.
Thank you for the feedback! I mentioned the sizes of the orings and part numbers near the end of the video, and provided links to the schematics in the description. I will add oring sizes to the description as well. Thank you for pointing this out, happy you enjoyed!
Thankyou so much now I know my guns reg problem..I am facing leakage from the reg adjuster as well having reg creep...though my gun is brocock bantam sniper xr I think the reg is similar
Hello! Thank you for the video. I'm having problems with my new Maverick.. The 1st reg on my gun passes all the pressure from the bottle back to the second regulator. This happens even if the 1st regulator screw is all the way at the bottom. What O-ring should I change on this case? 😀
Hi i find all your videos very informative and i have just bought a new fx maverick ,well while setting up the rifle for the first time , and while setting up the pressure for the ist regulator i discovered a leak in the tuning screw of the first regulator (while turning it anti clock wise it starts to leak , pls suggest possible cause and solution look forward to your suggestion thanx
I am replacing regulator on my Maverick, after i have tried a Huma one that dident work well for me. So as putting in the Huma one was easy i assumed it would be the same with the original FX one, but no it leak thru the atmosphere leak hole, so i replaced the O-ring at the bottom of the housing, and it still leak. So i try to put in the Huma one again, and now it also leak thru the atmosphere leak hole. Starting to get a little frustrated here. Regulated pressure do not creep or bleed but it will bleed the whole bottle dry overnight so there are 0 pressure in front of the regulator ( .177 so reg set to 100 BAR )
Thanks for such a good video and info. I have upgraded my fx mk2 fac regu to hima-air reg high pressure 110 - 165 bar. After installing the new regulator I faced some problems as follow: 1st was the washers arrangement. regarding the manual they said I can put 14 - 16 washers when I tried 15 for example the reg itself didn't close very well and it stuck in the trigger. 2nd was I found that when I did my arrangement as 14 washers and adjusting the reg to 115 I faced 2 things when I fire a pellet the regulator gage returned back to 115 very slowly 🐌 may be it takes 15 - 25 seconds. The other one was when I leave the gun for two or three days I found the regulator gage becomes 120 or 125
I apologize, I am not experience in Huma regs as I do not work on them. I do not know their tolerances or solutions. I recommend reaching out to Huma 👍
Thanks for your videos. I have a perplexing problem with my Crown AMP reg, I have problems with the reg pressure rising with every shot. I have checked the reg screw to see if it moves but it stays put. I've checked all the orings seem to be fine, checked the spring washers fine too. Could not figure out what was going on. So I put a Huma reg in and everything is working great. But I'm still wondering what would cause that problem?
Sometimes an o-ring can be bad or faulty, even if it looks perfectly fine. The pressure rising with every shot is a more rare form of regulator creep. Even so, the culprits were either the regulator piston, or the lower o-ring on the regulator screw. Hope this helps!
Thank you very, very much for your videos, they are very useful. I would like to ask you how I can repair an FX Dreamline that leaks air at high speed in the area where the bottle is screwed in (not in the area of the adjusting Allen screw). And also if the origin of the problem could have been a dry shot to lower the pressure of the regulator. Thank you very much.
A dry shot can cause a leak from the atmosphere hole, but that is very rare. More than likely, if it occurred after a dry fire, then the O-ring around the Delrin regulator piston is what is damaged (4x1.5 nbr70). Might as well change the same size o-ring inside the bottom of the regulator housing as well while you have it apart, though.
@@910AirgunTuningandRepairs Thank you very much. This problem happens within minutes, hours or even a day after removing the bottle. But, if I leave the bottle connected with its pressure, there is no air loss and the regulating chamber maintains its pressure. The question is: is it convenient to leave the bottle connected at 230bar or is it better to remove it every time you put the gun away? And if I leave the bottle connected keeping the pressure stable in the regulation chamber, but there is a damaged o-ring 4x1.5 nbr 70, can this damage the shots?? Do you have any way (paypal etc...) to help you with a donation for your help? Thank you very much again.
Excellent Work!! Your video is one of the most complete and comprehensible review of operation , type and parts of the FX Impact regulators. Thank you so much; I'm most grateful for your post. I have a few questions though, at minute 8.33 you counted 15 washers for the 8mm reg, but in the pictures at the end you show only 11 washers are used. So with the 8mm reg we can use the shorter piston with 11 washers or we can use the longer piston with 15 washers? Is this correct? My gun has the 8mm reg with short piston, identical to the one from your picture, which means is not AMP therefore I can't adjust it to lower pressure when the gun is under pressure; is this correct? I replaced all the "O'" rings in my reg, put new washers and new piston (the shorter version), I pressurized the gun to 130 BAR, and the piston O ring blew up with a loud bang. That O ring came with the new piston from FX. I replaced the piston O ring and made sure everything was installed correctly, and the second O ring blew up just like the first one, (split the long way like you would cut a bagel in half to put it in the toaster) All the air went out through vent hole. Do you have any clue why is this O ring blowing up?
Thank you for watching! I apologize for the confusion with the washers. The 8mm regulator had two versions, a short piston then a long piston. The short piston naturally comes with 11 washers, the long with 15 washers. If you have a short piston, then you can only use 11-12 washers. Yes, you are correct, do not lower the regulator pressure while the rifle is pressurized, or you can very easily damage the regulator. From the symptoms described, it sounds like you rifle may actually need the longer regulator piston rather than the short. I believe I remember talking with you on the phone at FX USA about this very same issue. I hope you were able to get the new parts and repair the regulator. Please let me know if not. Thank you again!
@@910AirgunTuningandRepairs Hi Newman, thanks for your response. Small world! Yes, we talked on the phone after I posted the questions above. I didn't know at the time when I posted, that you are an FX technician, the most qualified and most knowledgeable person to answer my questions. Thank you so much for your help. Yes, FX is taking care of me. They promised to send the parts so I'm waiting to receive them. In the meantime, I figured out an undocumented feature, :) of the Impact 8mm reg. If I install 13 washers with the short piston instead of 11 washers, the gun works fine, it doesn't blow the piston O ring and has no reg creep. The only downside is that it's hard to make finite adjustments; within half a turn of the adjustment screw, the pressure goes from 100 to 160 Bar. But otherwise, it works fine. Thanks again..
Excellent demonstration tried to look for an answer to my M3 problem when iI remove the 580cc air tank, the air from Reg 2 gets out through reg 1 so rapidly, I changed reg 1 thinking it might be damaged, money was wasted, I have a spare reg 1 now lol. do u think its reg 2 that needs rebuilding ( or upgraded maybe to HUMA gen3 Extreme)? I will wait for ur answer before i step any forward with the gun
The air escaping once you remove the tank is not a problem, that is normal. There is no back valve on the regulators, so there is nothing to prevent them from bleeding out once the tank is removed.
Great video, thanks. The reg on my MKII Impact has just had the reg piston replaced by a reputable gun smith here in the UK. I have noticed the reg has started to creep from 135 to around 150 bar. The pressure in the bottle was at 210 when I noticed it. What do you think could cause this? Thank you 🙏
The bottom o-ring on the regulator screw is the most common spot for regulator creep. I would suggest swapping that o-ring, or possibly the regulator screw itself.
Unfortunately that tool is not longer produced/sold, as they were all hand made. We are working on a design that can be efficiently mass produced and still be affordable, no one wants to pay $20+ for a tool that only works a couple times 👍
The Maverick is one leaky beast. Got a new Maverick today from Baker Airguns, and has multiple leaking areas. Pisses me off they didn’t even test the rifle before sending it.
Sorry to hear about your Maverick,, but All of the rifles are tested, multiple times, but every time a rifle is degassed and regassed, it starts the process all over again, and leaks can arise.
@@910AirgunTuningandRepairs I sent the rifle back to FX-USA, and the Tech opened it up, and said one of the o-rings was chewed up really bad (where the plenums connect). I never disassembled it, so not sure if it was a returned gun to Baker Airguns, where someone messed it up, or it was trashed from factory. I got it back just a few days ago, and no leaks now. 👍
Brilliant video 👍. My brand new Impact is suffering from reg creep. Due to my location the supplier has sent me the parts to do the work myself to limit repair times. I’ve replaced all reg oring, polished washers cleaned, contact faces on piston etc and no damage or wear on any of the components but it continues to creep. After leaving the gun for 20 minutes the first shot is around 50-70 FPS low and the reg gauge appears to rise a little. I’m really stuck what to do now, any help or suggestions? It’s a .25 impact currently running 115/120 reg pressure. Any help or advise greatly welcome and appreciated
I would suggest a new regulator piston and regulator screw. Or adding an additional washer to the stack to make it more stiff, but this may prevent lower pressures.
That’s the exact same which is happening to my fx Dreamline they have the same reg I polished the piston and replaced Orings but still creep did you manage to sought yours out?
Excellent content: Question I have an Impact MK2 been sitting for a while with no bottle, When i screw on a bottle air is forced from the regulator vent hole. I have disassembled and reassembled and still same result. Everything looks clean and o rings are not damaged. I could see if they need replacing it would leak some but this amount of leak is a lot. Any ideas?
first, the guns are best stored with air in them. I had same issue when i degassed mine to add a hammer weight. I had a bad Oring located in the parts schematic C section #39 fx part number 19790 oring (mentioned in this video). I tried to fix it myself, and it was an absolute nightmare to remove a hardened oring in that location. After 2.5 hours i was able to take the old ring out in 2 pieces. After i replaced everything id lose 1 bar per hour on the tank side. So i must have scratched the oring seat, the replacement part is $270. So send it out man don't take a chance. Every other oring in this area is easily serviceable and if you want to try all the others first get some spares 1x19696 6x19731 1x19109 1x19225 in addition to an oring rebuild kit. Also FYI the Captain o ring kits are only durometer 70 so i wouldn't use them in this area of the gun. Good luck
Thanks for the O-ring diameters and part numbers! In the video you mention that the outer housing O ring is 90 durometer but in your description it's 70. Could you please verify that? Cheers!
My apologies for the confusion! The 7.5x2 (around rim of housing) is a NBR70. The o-ring that goes into the action that seals the base of the housing is a 10x1.5 NBR90. Hope that clarifies!
@@910AirgunTuningandRepairs Thank you! I also didn't know that they had schematics on the FX website. Thanks to your video i was able to reference the parts list there. Thank you!
Hello, I congratulate you on the material ... very good explanation. I need your help, I have an FX Impact X to which I install an internal (original) power plenum to take full advantage of this new great capacity ... should I update my regulator for any particular version? Any recommendations if I go for a replacement for an original FX or HUMA. Note; I use my rifle in .22, .25 and .30 caliber, 700 mm long. Can you guide me? a greeting
With the FX power plenum, you will not be able to use over 150 Bar regulates pressure, so the original regulator is fine. No need to change it if it is working now 👍
How do you remove the reg in the first place? Do degas remove bottle the take out the reg adjuster screw, then how do you remove the reg body? Sorry if it's obvious I just don't have the rifle with me at the moment to see cheers
Hi,.. i change all orings,... I have 2 incidents please ask for help, the first the tank loses a slight pressure from one day to the next,... the other is that in each shot the pressure of the regulator drops and it takes time to recover the pressure in the regulator that had been established, . What oring is the one that will be failing? I hope yoy feedback please,.. thnks since Monterrey Mexico
I am not sure which rifle you have, but I see your other comment that you found the leak on the regulator atmosphere hole. A leak here would also cause slow regeneration between shots
depends on the rifle is came out of. Typically no, it should be 11, but sometimes 10 very thick washers can simulate 11 washers. If you cannot reach desired regulator pressure, add a washer
Hi my piston es of 16mm, what orings have to use..?? Old style.?? Or that other one.??? I put all orings new on size that you say but it has a leak on one side, through the drain hole. which oring should I change to some other measure of where of which piece ? I appreciate your help
Which rifle is this for? If you replaced the o-rings with the correct sizes for your regulator, then it should not leak, unless there is other damage to the pieces.
Olá, você teria algum video para me indicar, de como retirar o vazamento pelo orificio lateral da Fx Crow ? Quando eu coloco ar pelo engate foster o ar vaza pelo orifício lateral, não enchendo o cilindro da Crow .
The atmosphere hole leak is caused by either the o-ring on the piston, the o-ring inside of the brass housing, or the o-ring that fits into the main block (seals around the brass housing). There is not a specific video show casing this exact repair, but there are videos showing the removal of the regulator from the Crown. Hope this helps!
The regulator will only lose pressure when 1) The tank pressure falls below regulator pressure, 2) the regulator is leaking, or 3) there is a leak after the regulator (somewhere in the valve assembly), but the regulator has not opened to accept more air. Let me know if this helps!
Adding a washer will make it to where you do not need to back out the adjustment screw as far to reach higher pressures. For example (fake scenario), if before, 1 full turn out gave you about 100bar on the regulator, when you add a washer 1 full turn would give you about 120 bar or so. There is no exact measurement on how much it adds, just a knowledge that it allows you to achieve a higher setting faster. You should never ever go over 150 bar on a first gen, unless planning on replacing the regulator within 1000 rounds.
910 Airgun Tuning and Repairs If i change my regulator for a Huma first generation regulator high performance 145-190...is that ok for a Impact first generation ?
@@GillesQuennevilleGQ you can change the regulator if you like, but to get higher velocities over 155bar regulator pressure, you will need an aftermarket hammer weight to properly open the valve. The FX regulator can do the same as the Huma, just won't last AS long as the Huma, but if you are running 160+Bar on that short piston set-up, parts are going to wear out faster than at normal pressures for either brand. You will see vast improvement from adding the hammer weight and 6.3mm titanium valveseat, the Huma will just last longer than the FX at the high pressures. Send me an email to 910airguntuner@gmail.com of you need help finding the aftermarket parts.
Today i have changed that o- ring which is very difficult to removr at the cave of regulator in my fx impact . When a started to fill it the air blown away from that tiny hole upside of grip . I opened it and change piston o ring and i tested it again . Same problem i got . Air blew from the same hole . I dont know the problem. Where A regulator screw was flash 😔
You may also need to change the oring inside of the brass housing. Either that, or one of the prings you installed was a bad oring unfortunately. Sorry for the bad news!
@@910AirgunTuningandRepairs i realized that the regulator piston is demaged . I decided to order a new huma regulator so it will come completely with its piston . And i will see after that. Thank you for your help reply.
Fx impact mkii pp ,do you help me , the three spring washers are 0.60 millimeters thick, and the remaining eight are 0.50 millimeters thick. I want to know how to install them correctly depending on the thickness? With regards 🌹
I need your help please . Now my fx impact regulator gauge is matching a bottle gauge . When pressure in the bottle is 200 and the regulator is 200 . So so which o ring should i change in the regulator . Sorry i'm a new airguner
The AMP regulator should be 10mm diameter washers, and only 12 stacked. In rare case of all thin washers, there are more on the stack. In any case, the AMP regulator should be stacked the same, like the following: ( ) ( ) ( ) ( ) ( ) ( ) If you have more washers, just continue the sequence. For instances, 15 would look like: ( ) ( ) ( ) ( ) ( ) ( ) ( ) (
Thanks for your response but would this setup allow me to adjust the power between 90 and 140 bar? as it is now, it only allows me to get 80 or 90 bar when the regulator screw is almost out.
@@mohammadsiameldin7745 was the rifle originally a 12FPE or a lower power gun, or was it always a full power gun? If it was not originally full power, I'm guessing the spring washers are thinner/weaker to match the gun. That's the only reason I can think you cant get over 90 Bar. Or you have a fault regulator gauge.
Where does the bigger 10x1.5 oring go ? I have never seen this before , I also have had 4 leaking dreamline bottle adapters , I get air coming out the vent hole , can any one help
The 10x1.5 goes into the threads of the bottle adapter, where the reg housing threads into. You may be able to see it if you shine a flashlight into the regulator bore, but you can certainly feel it if you run a cotton swab or dull toothpick up the reg bore threads, you will feel the o-ring about 1/4 of the way up.
910 Airgun Tuning and Repairs ah yea I found it , sneakily hiding lol, I’ve had 3 proper leaky bottle adapters from Fx recently, I have changed orings and still can’t get a seal , Johan is sending me out yet another bottle adapter that will be tested in factory before being sent 😅🙁
Gen 1 is produced before May 2017 (serial number will start with 15. 16, or 17). Gen 2 is May 2017 until serial number 183543 (has longer 16mm piston). Gen 3 is serial number 183543 until MK2. Gen 4 is MK2. Gen 5 is Power Plenum. The AMP regulator is in Gen 3, 4 and 5.
Thank for reply. I am order the wrong one. I’m so sad about that. I have order gen1 but my gun is gen2. If you reply faster than that maybe I’m not wrong. Can I use gen 1 for my gen 3?
@@jennysok I apologize, I try to respond as soon as possible. No. Regulators are not interchangeable, a gen 1 can only use the short piston. Gen 3 (AMP) can only use the AMP.
