Well sh*t…
Okay, so many of you chipped in with advice when I posted about my inconsistent velocities, and I tried everything people suggested – cleanings, lubricants, new hammer and spring, the whole 9 yards. Nothing worked, so I decided to take the valve out of the tank. I started by sticking a 5/16 drill bit into the hole in the valve body, and trying to tap it loose. This did nothing but give the edge of the hole a slight oval shape, so I took out the burst disk retaining screwm and as per instructions I found on here, I threaded in a regular screw, and gave the screw a few taps. After a couple of shots, I SHEARED THE THREADS OUT OF THE HOLE IN THE VALVE BODY. That’s right, the threads are toast, and now the burst disk retaining screw will not go back into the valve body. Needless to say, I am pissed. So, here is my question – should I send the bottle and valve back to Airforce to have it repaired, or should I order a new valve body and send it to someone who could tune it while it is off? If you think I should go with the second option, who do you recommend?
Thanks again,
Chris

It was not necessary to remove the disk itself when ive taken mine out, only the retainer grub screw. I screwed the proper thread bolt in till it bottomed, secured the tank in my vice wrapped in a magazine, and a few taps with a mallet it broke loose, although it did bend the bolt. A spanner wrench of the right size would be another option. Make sure you drain the air first. 😀
As I look at the quick reference section about valve removal, it mentions removing the burst disk. Apparently my mistake was only removing the hex nut, and not the entire burst disk assembly. Dammit. Anyhow, I can’t seem to get the burst disk loose. I tried tapping the valve body against my workbench, and I have tried pulling it out using some wire, but it won’t budge. Any thoughts?
Thanks,
Chris
buy a valve body and follow the valve tuning tutorial in the quick reference section.
It is pretty easy to do.

I got mine out by taking a piece of copper pipe and cutting it so it would wrap on the valve assm. put it in a vise w/ magazines to protect the bottle and used a pipe wrench. drill a hole in the copper pipe to match the one on the valve. stick a bolt in so the copper pipe doesnt slip around. pain in the ass but it works without harming anything. think i found this idea in the quick reference section. good luck!
