    [Edit]  Heads up – Before you start reading / scrolling:

    After a few e-mails with Pyramid Air [Where my PB was ordered from]
    They'll be taking care of this issue via their [Air Venturi] 1-Year Warranty.  *Stoked*

    As my 'luck' would have it,  my favorite air rifle just s**t the bed..  *sigh*

    I was shooting, when a pull of the trigger cause what sounded like a fully automatic – wet fart..  🤣 
    That obviously caught me off guard,  so I re-cocked the gun, and tried to fire it again..
    Same deal..  I've heard the horror stories about broken valve-stems, so I assumed that was it.
    **There was no noise that would indicate a metal part failing/snapping though**
    That said,  I'm hoping for a better case scenario.. 

    Depressurizing was a breeze,  I just held down the trigger, and all the air rapidly escaped..
    After a few seconds, the air-tank was completely degassed, and the gauge read zero.

     

    With things safe to work on,  I figured I'd start tearing into the action to inspect things..
    Before I could even remove the internals,  I noticed that there was a small o-ring out of place..
    It appeared to be smushed against the retaining set-screw, and it didn't look very healthy. 
    [The o-ring ended up being chopped in 1/2,  so now it's just a rubber-U]

     

    I removed the set screw, marked / removed the rear adjuster, spring, and hammer cylinder..

    I stopped there,  since I haven't torn down this rifle before..
    At this point,  I'm questioning whether the o-ring could have been the issue?
    I'm clueless at this point, so I wanted to ask first..

    I have no idea where that o-ring came from, so hopefully someone does, and, 
    *fingers crossed* that Kral included a spare somewhere in the box..

    Also – If I do end up needing any new replacement/upgraded parts, 
    could someone direct me to a good source who'd respond asap and have them in stock?

    I'd Really like to repair this and get it back in action as soon as I can!

    Thanks in advance!

    Dont know the kral's, only time I've heard that brraapppp sound on an airgun was insane hammer bounce at minimum pressure dumping the tube, who knows.

     PA sells em now tho FEW parts listed, certainly would be my first try for parts.

    John,  

    Yeah, 'pressure dumping' is exactly what it did.. 
    Where normally, you pull the trigger, the valve is opened/closed quickly and a small burst or air is released..
    When I pulled the trigger,  it seemed that the valve would just stay opened, or open/close with extreme speed..
    As long as the trigger was pulled, the air would dump out of the gun [through the barrel]

    PA – Thank you for the suggestion!

    PA is where I ordered mine from on Dec 8, 2018

    I shot an e-mail their way describing the issue, and asking for their advise / info / etc
    They list a "1-year limited warranty",  but,  I'm not sure that this could be covered..  I asked about that also.

    Parts wise,  unfortunately,  they don't seem to stock very much.
    I was going to order a replacement cocking-lever when I ordered the rifle, but, they were pre-order only..
    A few other parts that they had listed are no longer available now either,  so yet again,  just my 'luck'..

    *Fingers Crossed*

    I think it may well be the o'ring from the valve stem. 

    Pyramyd Air stocks the entire valve stem/o'ring/poppet last time I looked.

    Nice neat organized work area you got setup, thats key imo…

    Just keep on taking it apart, you'll find whats wrong soon. Just keep going in a neat orderly fashion, being gentle, not forcing anything, just like you're doing so far. Take pics so reassembly won't be a problem.

    Or send it in as its probably still under warranty..?

    HeyU, 

    Thanks for the suggestion!

    I actually have a PDF and a hard-copy of the Kral Arms PB owners-manual [The same as what they have on their site]

    I've tried to contact Kral directly in the past [trying to purchase their other accessories] but unfortunately, they don't respond..
    2+ months and still waiting for a reply since the last e-mail I sent then.  haha

    **The diagram I've been using – Trying to figure out where that mystery-o'ring came from:

    Mike,  

    Thanks for the info!

    I contacted PA – To see what they'd say first..
    If there's no warranty for this,  I'll keep digging farther into it myself..

    Having that sort of o-ring / seal go bad could explain the sound[s] and issue..
    Like I mentioned before – I didn't hear any sort of loud or metal/metal sound..

    acs,  

    Thanks a bunch for your thoughts, advise, and video!

    Yeah, 90% of what I do is from being 'self-taught', and OCD er', I mean…  Organizational Skills is one important thing I learned along the way..
    I try my best to keep things in order, and yes . . . Lots of pics or video of things as they come apart.  That's a must for me, as I have a bad memory.

    I contacted Pyramid Air last night / this morning – I haven't slept yet..
    Just waiting to hear back from them, so I'll know how to proceed..

    It'd be Great if something like this falls under their [or Kral's] warranty, so *fingers crossed*

    =)

    Give Troy a call at Annihilator Airguns and Tuning. He specializes in Kral airguns but can be hard to get ahold of sometimes or see if JSairguns has anything available.

    DD     Crap ! is all I have to say & I'm  sorry for you to have to go thru this . I also bought a 22 cal. pb at Christmas time on sale $379 . How many rounds have you got thru that thing ? I just love mine & it's very accurate . The past couple days I have been looking for a diagram (a good one) the only one I found was on the kral site . Just wish they were like the ones crosman puts out . My intension was to buy some spare O-rings & parts for pre. maint.  Does anyone have a list of O-rings & sizes ? please list I'll give you a + for sure because I was just about to do this in a post ! As far as PA everything that is listed is OUT OF STOCK ! . what does that tell you . From what I recall JS airguns had a o-ring set . I'll keep doing research for ya because I also want some spare parts on hand . Keep us posted what you find out & I believe I seen somewhere it has a one year warn.  Best of luck Darell

    Imold, 

    Thanks for the suggestions and pic!

    I was actually on both sites, looking over options – both before I ordered my PB, and recently..
    Either people are unreachable, or, parts are listed as being out of stock,  I didn't have any luck.

    At least an o-ring "kit" is available..  That's cool..

    Darell,  

    Thanks a bunch!  I swear,  If I didn't have Bad 'luck',  I wouldn't have any 'luck' at all.
    Right on,  that's a great deal you got on your PB!  I absolutely love these rifles,  and of the handful I have, 
    even though it's one of the cheapest,  it is definitely my favorite!  Which is why this really bums me out!

    Rounds – Ohhh…  just a few…

    1 tin of JSB 15.89 gr / 500 count
    2 tins of JSB 18.13 gr / 250 count  [1,000]
    3 tins of Crosman Premiere 14.3 gr / 500 count  [1,500]

    And,  I started in on a tin of H&N 21.14 gr / 200 count 

    So,  the shot count is right up there with some of the other rifles that fell victim to failed internals..
    With my bad luck – That's what I was actually expecting.  So if this is just an o-ring issue,  that'd be Great!

    I usually keep checking sites – looking for replacement parts – just to be safe..
    That's why I'm a bit bummed that none of them seem to be easy to get in touch with, or, items out of stock..

    An o-ring diagram would be awesome!  I was also trying to figure that one out too..
    My auto accounts/suppliers used to have o-rings priced at like $0.02 cents to $0.10 cents a piece..
    That said,  a full o-ring kit 'should' be super cheap.

    It'll take someone with a set of calipers, a full kit, some time on their hands, etc. to put the info together..
    O-ring size / type – hard / soft.  Even sites like Fastenal / McMaster-Carr will carry them in bulk.

    Thank you very much for keeping an eye out also!  And I'll be doing the same!
    If/when I run across any helpful / related info,  I'll be sure to post it on here,  and,  probably PM you too.

    As for warranty – Yup,  PA lists a "1-year limited warranty",  but no clue what that entails – yet..
    They've been e-mailed,  I'm just waiting for a response.

    =)

    kkarmical,  

    Thanks for the vid!
    I watched a few of these before my rifle arrived – Just to know what was 'involved'..
    I'm going to have to try to spot the mini o-ring that I have here – which I keep missing in these vids..
    Still trying though!

    Darell,  Thank you for the heads up!

    Yeah, I think the ones that came on my fill probe were a bit sketchy too..
    I also have a Hatsan gladius, so I just use that fill probe for both..  It fits much nicer and tighter.
    Upgrading o-rings would probably help a Lot though.

    =)
