FX Impact Broken Regulator

[vladb]

Hey guys,

I have successfully destroyed regulator on my FX Impact rifle! It leaks air.
I am not really sure it is really my fault, since I really tried to turn it counter clockwise under the pressure only.
No clockwise attempts under pressue. How does it break if it is turned clockwise? Does it leak air? Or just doesn't hold pressure?

Thanks

"vladb"Hey guys,

I have successfully destroyed regulator on my FX Impact rifle!

You sound happy you broke your gun after multiple attempts to destroy it.

Well... it was just one attempt really. I was adjusting regulator couple times before with no issues.
It could be a developed problem that I had earlier when regulator was not holding pressure very well, it was raising up to 15 bars if I leave rifle for several hours.

You might not have damaged the regulator piston but just an oring. Have a good look at Ernest Rowes video on the subject. 
If you turn the regulator clockwise under pressure you force the the piston which is relatively soft material against a small brass nipple. This is basically the on/off valve between the high pressure side and regulated side. 
If you damage the piston it won't do its job and regulate like it should but shouldn't leak air.

Most likely the 9x1.5mm o-ring inside the regulator housing is broken. 
It used to be a 9x1.5mm nbr70 but it has eventually been repaced by FX for a nbr90 ring (which is a bit harder)
This is a known issue of the Impact, I've seen them gone south numerous times, including mine.

AOA has made a very good video about the regulator overhaul, but the o-ring is hard to see in black impacts, and it can be a struggle to get the new ring in.

Good luck,

Gijs

vladb, you can try first to cleanup then relube the regulator by following the instruction from AOA video below. It's easy without the orings replacement.

If that doesn't help then you have to replace ALL the orings in the regulator. The C39 oring is a pita to replace, especially if your Impact is back as you cannot see it at all.

Trouble is ... if he tries to fix it by himself and is unsuccessful at doing it right, then tries to send I to AoA to fix it ... he has just voided his warranty if it is still under warranty. That could be a pretty costly mistake.

Yes they made it clear that it will void your warranty in that video if you try it yourself. But for a second owners like me or longtime owners it worth a try. For a 2K price, i think FX should offer at least 2 years warranty.

Thank you guys! So, it was not me really. Which is good.
