Classic RT Issue

[jbtamu1011]

Well, having an issue I've never seen or literally heard before. When I aired it up, air came out the back of the valve where you would adjust the velocity with a hex. It was soooo loud and sounded like a jackhammer!! I replaced the orings but not sure if I missed something. Is there a exploded view of the classic RT valve? I've searched here and google with no luck.

they are the same internally as rt valves with the exception of the banjo bolt and maybe being milled for the 2nd on/off oring.

sounds like your reg piston is toast.

Is that hard to fix? I only have experience with oring replacement.

no, it is the brass piece under the velocity adjuster, just buy a new one and put it in.
