    s410 cylinder change..

    hi all,
    this week, if all goes well, i should be finally replacing my small t.d.r cylinder with a larger 410 one,
    a couple of questions,is there a better way to empty the cylinder than just firing the rifle until it dies ?
    and how easy ect should it all unscrew ?

    im just after any pointers that i should be aware of before i "go in",

    thanks,

    JASON..

    I have completely stripped and repaired the aa400, so the aa410 shouldn’t be much different apart from the multi-shot mag.

    The only way I can think of is dry firing the gun till empty.
    The cylinder should come off very easy, but on new guns they do tend to put a drop of thread lock on the thread to stop movement, so sometimes you may need to heat the back end of the cylinder with a hair dryer to release the thread lock.

    The cylinder just unscrews off anti clock wise.
    Very easy job to do.



    Regards

    As Reply says, dry fire it empty. You will need a strap wrench, either bought, or home made. It might be an idea to check the O-rings. The front filler valve block should come off if you put a spanner on the filler itself, but you will need to make up a pin spanner if you want to remove the filler from the block.

    It's easier if you remove the barrel and breech block first, just watch out for the little o-ring below the breech block

    Whilst you've got it stripped down, why not replace all seals for peace of mind?

    thanks guys,

    so is it prefarable to dry fire rather than using pellets ?

    although saying that, i can see that as it reaches low preasure there may not be much point to grouping

    thanks,i should be starting on wednesday evening after a quick visit to the range

    If you're at the range, just shoot out your last fill until the pellets start to drop, then dry fire 'til the gun empties itself when the hammer spring overcomes the valve spring. You will hear a "Hissss...!" then you know the cylinder is empty.
    When its all back together again, don't forget to cock it before the first fill.

    While you are in there and going to all this trouble, might be worth replacing the valve too. They only cost about 4 and apparently, the new one is supposed to be more efficient, giving a few more shots per fill.

    hi all,

    went to the range and shot 70 shots,until the gun was starting to string downwards with every shot,
    the guns valve seemed to be stuck on 50 bar ,
    back home,and i fired air through the gun about 8 times before a very feeble "wizz" of air came out,
    right,out with the mole grips and the scrap of leather belt i always use and within 10 mins .. it was all done
    the end filler part was slightly "harder" to unscrew,although it was quite easy to remove,
    i re-screwed the end filler valve part way back in while i used the grips to unscrew the cylinder,

    both cylinders and gun

    inner valve tube thing

    i had thoaght with the longer tube on that the tdr silencer wouldn't fit,id already got a "ukneil" adapter on standby
    but it still fits (which made my day )

    clearance of cylinder and silencer

    i grabbed the hills pump and filled her up to 180 bar and several hours later its still all in ,
    and it still all fits in the t.d.r bag/box
    i can feel its now slightly more front heavy,
    i think im going to like this gun better now
    il be back out on friday givin it a go,and poss a run through my cb625,

    cheers guys,

    Glad you're sorted, they really are simple guns to work on once you over come the fear of high pressure compressed air

    Is it possible to check and clean the inside of the cylinder once it is off?
    I use a Pump rather than a bottle and was wondering if it was time to check for corrosion or grease from the pump.

    Its quite easy to take the front filler block off, and have a look. if its started to rust, replace the cylinder. (And get a bottle..!

    i had a good look inside both,and there was no rust or anything on the surfaces,
    but removing the filler valve is a realy simple thing to do,

    im thinking about getting another bottle as im always cream crackered with the hills pump
