I have been workin on my sons 1377. When you shoot it you can feel air that come from under the breech. I put in a new breech seal and a new bolt seal and still feel air!! Any ideas!!! ???
Make sure your barrel and valve is lined up with the breech seal also did you put the breech screw back in and is it tight. sometimes the barrel will twist and not line up right.

Mike is right. Check that the transfer tube is fitting into the barrel port. I ususally center the barrel port on the breech and lightly snug the barrel set screw. Just as I marry the breech to the pump tube, I will loosenn the set screw so I can wiggle the assembly together. Also, remember that the shorter part of the transfer tube fits into the valve exhaust port.
I have done all of that. I do'nt know what else to do. That's why I am beging 4 help.
which variant is it?
Does the valve build pressure and hold air?
It builds persure and holds air. iT JUST BLOWS AIR WHEN YOU SHOOT IT? I THINK IT IS MAYBE A PHASE 3 ???
What's the first four digits of serieal number?
Find an adjustable flame; disposable lighter. Unscrew the adjustable flame valve and remove the o-ring. Use this o-ring as a top seal on the transfer sleeve.

It's the o-ring on the left.
Thanks CMJ, that's a great thread.
Thanks , I will try that today :-* :-*

Imitated it myself and it does work :-*

Bics are too nice to destroy anyways. I'm buying one of the clear cheapies.
not when they are empty
the flint spring in a big is a lot better than the spring from a cheapo
Goodpoint. I just threw out a bic a few days ago too. >:(
Are the o-rings different in bics compared to cheapies?
same thing i want to know i have a spent bic gotta go to the dollar store and get a 7pack of cheapos
i should start selling o-ring top seals.at 15 cents a lighter $2 a top seal delivered should sell with a safetu spring included ;)

There ya go. :-*
Some Bics are adjustable and others aren't. I have only found O-rings in the adjustable lighters but most of the cheapo lighters I have found are adjustable.
Cheers,

Only the adjustable flame lighters have the o-ring.
Everytime I see thrown disposable lighters I pick them up take them apart for their innards. The cheapo ones are very cheap here at P5.00 / $0.11

This rubber thing looking like a screw is also from a disposable lighter..This simple mod has eliminated the slack on my 3 Crosmans so now they are a true single stage trigger..If you would notice while cocking the gun the trigger exhibits a nodding motion right? If you squeeze it slowly there is always this terrible sluggishness. Now this domehead rubber thingy being pliant creates just the right tautness and puts your trigger in a semi-tensioned state making it crisp..On my 1377 the thickness was just right but on my two 2400KTs I did a bit of fine-sanding (#1000 sandpaper) as the sears won't engage..I dunno if anyone has ever done this before but I tell you it really works
@Crosshairs
How do you secure it to the trigger tang (contact point) ?
Mr. Vet it's crossliner baby and not Mr. X'hairs aka AIRGUN HOARDER EXTRAORDINAIRE :D..It is glued on..Use the tip of a pointed stick as it needs an infinitesimal amount. The small disposable lighter o-rings work fine too and also that flathead rubber that has a tail..It is round but it has a tail that you need to cut off..I like this dome-shaped rubber though. Best regards.
Thanks CrossLINER :-*
What ever or when ever it works and is very hard to get it on the transfer port. But when you do it WORKS :-*
thats why i use a transfer port gasket split into two o-rings
there is a line that runs through the gasket in the center.i get a brand new razor blade drag it along the line presto two top seals

I love this idea, but one question for you:
I assume that after cutting it the "flat" side would face down and the rounded surface up? Or maybe it doesn't make a difference?

its usually flat on all sides, a stock crosman transfer port gasket is square-no round sides like a regular o-ring, once youre in the line take your time
if you do mess up and end up with a wavy cut put that side down the straight side will go into the barrel
Thank you sir. :-*
