FX Panthera valve replacement

[woogie_man]

Need help guys....

Working a panthera for a fellow member. We found that the valve pin was bent so we bought a new pin and seat from Utah. We have everything installed.....and we are getting air escaping through the valve pin retainer. Seals are lubricated and good, and not seeing any other issues.

I know I am missing something and it is irritating us to no end. What is it that I am missing?

Panthera is a 25 cal with the air bottle at the front and blocking plate in the back for a stock.

Thanks for the help guys.

Are you talking about the threaded holder.

I've chucked up 2 different valves in my lathe and there bent from the get go to an extent. They can be a pain to get to seal I'd check the ring in the front that is something I ve seen often 3 different guns the valve caps were a little loose and not quite enough valve stem hanging threw blew the rings

If all the o-rings are kosher, its possible the cap/ holder got damaged when the valve got bent.

That bent valve went through it not squared.

You talking the seal number 2 or 8?

Have done quite a few of the fixes when the guns first came out. Never had to replace the seat itself.

None of the seals looked messed up or damaged. Did relube them to make sure things are good.

2. You said "air escaping through the valve pin retainer"

 

[Ta-Ta Toothie]

So, is air escaping from #1. The threaded cap

 

[woogie_man]

Makes sense...not sure why I didn't change that. Will try and find one and see if it fixes the issue.

 

[Ta-Ta Toothie]

I'm actually surprised o-rings 2 & 8 survived the ride.

 

[Airgunmann]

Mine were o ring number 2 I never checked 8 which would only leak when the valve open shortly if you think about it a lot of valves don't have a o ring in position 8

 

[Airgunmann]

I wonder about making a peak poppet to slide on I don't know why it opens pretty easy now

 

[Ta-Ta Toothie]

8 definitely gets beaten up. You will know that whan excessive air escapes through the hammer chamber vent holes. A loop always helps for how tiny these o-rings are.

Less resistance due to the o-rings beat up maybe.
