Kral arms one pease alloy block.... thats the job less stripping less seals ...like the songs goes.... thats the way i like it 😁... helo from ireland...😉
Thanks for the info, would u say if an air arms s400 has a leak, a replacement of all seals (standard with a full service I assume?) would generally resolve the issue? mine had loss pressure down to nothing whilst in storage, initially couldn't get it to fill, but I can if I blast the air in quickly. But it loses pressure overnight now. You referenced the fill valve so I presume that can be something not covered in a service?
Hi Mark, thank you for your comments. A full service includes the stripdown and replacing of all seals, cleaning and polishing if component parts. Should any other parts need changing that will added to the service charge. If you want further information please email me at dvschesterfield@gmail.com
Hi mate, I'm just down the road from you at Huthwaite, what's the name of the site you've set up so I can follow you on there. I'm not on face book or Twitter so can't access you any other way. Thanks Dave
Do you have a video of changing all the seals? Iv got an s410 carbine and it looses air about ten bar in a night it hadn't done afore so am think new seal kit and fit it myself is there owt I have to worry about? Ps I am mecanicly minded. Don't want to take to bits and realise wtf have I done? Any help would great 👍👍👍😜🏴🦄🎣😁🤞✌️
You will need the tool to remove the fill end cap and know how to get the anti tamper caps out. Once your through that the rest is pretty easy . I have refrained from putting up a full strip guide as i service and repair a wide variety of rifles, if I show how it's done no one will need me lol
@@richdvs totaly get you chears for the info iv already changed the filling bit to new one with new fill adaptor had the one in your video but new one now wasn't to hard where in UK are you 👍👍👍😜🏴🦄🎣😁🤞✌️ Ps thanks for your help 👍✌️
Hi rich my s410 carbine is leaking from the fill valve, i have stripped it down and the domed valve and spring look ok is there not a o ring inside there? should there be or is it the outer rubber seal that seals it please? i know there is two O rings on the outer shaft that the fill connector seals against.. just looks strange just the domed valve spring assisted seating up to the alloy concave bit on the valve housing thanks again Jim
Hi Jim. Yes there should be a small o ring on the top of the none return valve, without it the air will just leak out. It's a small o ring, can be bought from" BiggO" Sheffield individually or as part of a full seal kit.
@@dvschesterfield8615 thanks there is a domed rubber seal on it i can see now maybe its worn? also doe's the alloy pressure Gauge housing use a standard O rings x3 they look to have a flat rebate in them or is it they just mould to this shape when tightened up? thanks again Richard
No, 5.5 relates to the calibre of the pellet, .22 is 5.5mm, .177 is 4.5mm. Speed is recorded in Feet Per Second or FPS and should be arround 550 .22 or 770 .177 as a reference
If you are dry firing your rifle you may get a little blowback from the breech seal into the mag well. The breech seal may need changing or the rifle servicing to make sure its all leak free. Drop me a message to dvschesterfield@gmail.com if you need it doing. Richard
@@richdvs chesterfield is a bit to far me to send for servicing but thank you for information rich ! I’ll try closer to home ( Sunderland) if I have any problem I’ll send it mate if that’s ok ?
Hey my friend. I have air leak in my air arms s510 at the air loading port. How to resolve this problem ? I want to show you on photo where exactly it is.
If its leaking from the filling adapter, make sure the rifle cylinder is totally empty, use an appropriate size spanner to remove the filling End(the silver T lock filling adapter). As you remove it make sure you dont loose the small spring from the none return valve. Remove the seal from none return valve and replace it. Its also advised that the seal between the filling adapter and the cylinder end cap is replaced.
I have an AA S410 Classic which has a major air leak through the barrel (it blows a balloon up placed on the end of the barrel in minutes). Which seal is leaking and what is involved in replacing it?
David Parnell That would be the exhaust valve, and it's located within the valve body. Essentially the whole rifle needs to be stripped to gain access to it. The air cylinder needs removing, the valve pot and spring, replace the valve and rebuild. If you don't have the experience or the tools please send me a email as I can do this for you. Richard Nash dvschesterfield@gmail.com
Sounds like your transfer port to me. Take the stock off and the 6 bolts under it to remove the barrel. The transfer port has a white washer that might be leaking. Replace it.
Because the air is blowing directly through the barrel it's got to be the firing valve, as it's the only way the air would constantly leak from the air cylinder. If it was the transfer port it would only leak when fired. The transfer port seal sits between the valve body and the breech unit, is a black N70s seal and will only show a leak when the rifle is fired.
Hi rich, can you help me please.. i was firing my s410 carbine and there was a rush of air from the rifle and obviously stopped firing, i tried to refill of my bottle and its just blowing air through barrel full pressure of the divers bottle going through the barrel, rifle worked fine before the Hiss of air escaping.. can you advise please what may be the problem many thanks jim
Hi Jim, thank you for your comment. Sounds like you ran the rifle below 60 bar as at this pressure the hammer will hold the firing valve open, causing the remaining air to dump. Refilling the rifle from empty: Cock the rifle ensuring the magazine is out and no pellet in in the breech. With the rifle cocked, start filling the rifle. You may find you need to give the rifle a blast of air to reseat the valve, then continue to fill slowly to 190 bar. Disconnect from the fill cylinder and discharge the rifle in a safe direction. Let me know how you get on. Richard.
Firstly thank you for your question. I have to ask why you feel the need to fit a regulator to your S510? The air arms S400/500 series are self regulating by means of a brass pot on tbe back of the valve body. You will also have to drill a breather hole in the air cylinder, probably have to drill the transfer port so, ask yourself this.....is it really worth fitting a aftermarket part to a perfect rifle. I am sorry to say I can not give advice on how to remove Anti tamper plugs/caps on any rifle but I can however remove them for you. Richard.
Big thank you for this video! I dicovered I have a leak on my exact same gun today and this has helped me out loads!!!
Another leak point is through the air pressure gauge, through the hole in the side of the gauge, if so, new gauge required.
How about putting a little bit of “spit” over the end of the barrel to check for any leaks from the firing valve?

Just under the mag indexer there is a very small grub screw when I dry fire there is a leak coming from it ! Is this normal ?

what is the easiest way in your opinion to remove the anti tamper to the power adjuster.
i'm fitting a reg to my s510 and need to open it.
cheers

i dont like the power curve' i like the way my galahad performs
hi rich if air is blowing through the barrel, which seal would be leaking? thanks!!
Ernie Amos it will be the actual firing valve that will be at fault. Requires a full strip down to change it
