Question Valve depth and spring length

Hi,

I have a really old phantom with a deep valve body. The spring is longer than the current CCI spring (but same diameter).
I would like to use a new spring in the valve, but it's too short for the pump to arm. The main spring pushes the valve open before the hammer latch onto the bolt.

I was thinking to machine a little spacer for the spring. I'm probably not the first to think of that.
So I was wondering if anyone have a good length for this spacer or if I need to experiment.

Thanks

I had to do the same thing in my nelson mutt. I ended up using a spacer about 3/8 to 1/4 of an inch.

If it were me (and it has been on multiple occasions - LOL), I'd just buy a new valve body ($19). Shims and spacers may work for a while, but inevitably fail, or end up causing additional band-aid fixes to compensate for minor tolerance inconsistencies. You end up with something that's just not reliable - which is the opposite of what a Phantom's all about. When I finally replaced all the internals on my original '92 Phantom, it made all the difference in the world - like shooting a brand new gun.

Thanks, it looks like a great start point.

I replaced so many parts on my old phantom I just rebuild it :P
That's why I got another valve (used) and it have the same specs. ..
Can anybody measure the valve depth from the opening to where the spring seat? Mine is right around 1.350"

As reference the old spring is 1.090" long and the new spring are 0.880" long

I finally had time to air it up, and it seems to shoot fine with no shim, but the hammer doesn't catch when it's not aired up ...

Now I need a chrono

That's good to know ...

My old phantom cock without air ... Always had ...
But new ones don't? So I thought something was wrong with my phantom when it might not have a problem at all? Always good to hear ��
