leaking regulator

[dyer]

hello all ,
After 3 years of not shooting I have decided to sell my regulated aa410 . It was empty when took it out to check over and when I filled it it started to leak at about 100 lbs .The air was coming from the hole drilled in the air reservoir so i am presuming it is the reg leaking.
So my question is can the reg be fixed (it is an airmaster 88 reg) or do I need a new reg ?
I would appreciate your thoughts
many thanks
Duncan
also what sort of price would reasonable for working aa 410 walnut stock in 177 ?

There'll probably be a tiny O ring under the reg internals that needs replacing.

Or the o-rings on the regulator body, the same happened on my BTAS regged s410.

Cheers for the swift replies .
another question if the o rings are replaced will the reg then need tweaking or will it be a straight swap ?

You can replace the external o-rings without any changes or resetting, I've never stripped a reg but would guess that you'd need to reset the working pressure if you changed the internal seal.

Same with mine a couple of months ago.

As said above, just pull the reg out (make sure the cylinder is empty first), change the o rings and re assemble. Will be good to go then...

Thanks for help chaps , do i just unscrew the air reservoir to get to the reg?

[andy coup]

You can do it that way, but every one I have seen done like this leaves scratches in the finish on the cylinder from rubbing on the breech. Best to remove the breech first.

This thread has demonstrated that you cant fix it so the sensible thing to do would be to contact Dave Welham at Airmasters and get him to sort it for you. It would also be a good selling point. That way if you sell the 410 it wont come back like an expensive boomerang.

hi just a thought ,can the reg be re-assembled wrong ? also take the breech block of turn it upside down and check the transfer port has'nt moved a little, you can see if the venture airway is ok also
