Help needed please Kral Puncher S Marine 1.77


Hi all, I'm looking for help on this, I'm in the middle of fitting a regulator

to my Breaker but i have come to a snag

and i have come across this, not got a clue where the hell from

, no its not the bolt from the trigger arm

.



thanks for looking

Hope you fully degassed it. It would be a real bitch unscrewing it under pressure as well as very dangerous. Unless you have suicidal tendencies...

 

[syotos6]

yeah its all degassed, its just the bolt like brass thing.

Oh when i put the rifle back together i was filling it and air was coming from down the barrel

 

[Yo]

Cock it first. Fill from a tank. Or plug that breech with couple felt cleaning patches or pellets 2 maybe 3 if 2 aren't enough to hold that pressure at your own risk put it on safe point in a safe direction while pumping.

That brass ring looks like it came from the stock where you put the mounting screw into the gun.

Good morning 

The only way to get the valve loosened out of the tube is with a heat gun it is put in with thread lock make sure gun is degassed 

Have a great day

Bud you wouldn't happen to know where and what that brasslike nut is from

I've never seen that brass piece on a Puncher Breaker before and I've disassembled over 150 of them. Possible it was part of an anti tamper which we don't have in the US. As far as leaking from the barrel. That's coming from the valve stem seal (Poppet). Rifle will need to be cocked and a blast of air from a tank to seal it or it's possible gotten damaged or debris stuck in the seal. Good luck

I honestly do not remember seeing that brass piece in mine.

The only brass insert I know of is in stock for the front lower bolt on rail.

Have my huma reg set to 110 shooting jsb 10.34 at 890 get like 75 shots before coming off reg

Good luck great gun

Gents thanks for all your help on this one.

Troy you are a star, yes in the uk we do have tamper plugs and after relooking over both gun and this bolt like thingy, it was the tamper plate i had to drill at the start..



Many thanks to all

I've fought w removing that valve from the same gun before. Like before mentioned you must use a heat gun to gradually add heat in a round motion as evenly as you can for 2 inches or less of the tube that contains the threads obviously. I've found it isn't like a pop and it's loose like a jar it's more like a very slow spinning with much drag when you do get the lock tight in there warm enough to give. So use a good spanner on the flat part where the stem comes out and either a strap wrench or something similar to hold tube. Obviously don't hold tube where threads are and don't crush tube (its pretty sturdy and would be pretty hard to crush IMHO) and once it starts to spin just keep spinning slowly until it loosens all the way adding heat if needed as u go. If you have any more specific questions message me please. Good luck and always degas by loosening gauge or brass plug first. Also u will most likely need heat to reinstall it all the way tight if u don't get it all the way tight ur barrel band grub screws won't align w previous original marks and the print on bottom of tube won't be aligned at the 6 o clock position anymore either so make sure it's all the way tight when done because the first 2 or 3 times u swear it's all the way tight and can't get any tighter.... It still has to go tighter!
