RT Classic Valve problem

[RehKal]

The threads the banjo bolt go into have been cross threaded. Can this be safely re-tapped or am I going to have to replace the entire valve assembly because of this?

Yikes, never heard of that happening, if you can't screw it back in i'm sorry to say but i think you might be screwed, but i could be wrong.

Screwing the banjo in isn't the problem :> It screws into the wrong threads though.

This poor mag has been through at least two paintjobs using brush on type paint. Metallic teal and a dark metallic violet. Then the rail and foregrip/sight rails were sanded down leaving all edges silver and the rest black. The original anno. Mismatched screws held the rails on and.. blah. Poor thing. Looks like it's time for a restore.

I'm loath to get rid or replace the valve itself because of it's serial number. RT00469 :/

Ouch, my RT is RT05319 so i can see what you're saying, because it was hard to find mine, but mine is also in immaculate condition (i got lucky, the guy treated this thing nicely, needed an oring rebuild and piston because of age, but other than that it was nice).

I don't know where you can get just an RT valve, as AGD never sold them, and i've never seen any for sale, and if it's cross threaded and you can't correct it i don't know what to tell you, look at the banjo, are the threads on it screwed up or are they on the valve?

The threads on the banjo are fine. I have no idea how but the previous owner managed to screw the banjo into the valve crooked and cut new threads into the valve itself. If I could find the correct tap I could probally fix it fairly easily. Because the oring should still be able to seal it.. the seal itself doesn't appear damaged.

jay over in the b/s/t section has classic RT valves. good luck!

Yikes, well since you've nothing to lose you can try finding the correct tap and tapping it out...

Does anyone happen to know what the correct tap is?

Monday I'll give agd a call and ask them personally for advice on what to do with it.

That's actually the best course of action, see if they know what the tap is, if they can fix it, etc. etc., or email them pictures of it. I feel sorry for that RT, almost feels like we should send it out to see on a boat that's burning at the melting point of steel.

It's had a hard, long life.

But it isn't ready to give up yet!

I put air into it to find the leak and just had to pull the trigger a bit. Thing fired so fast I couldn't believe it.. even with the leak!

[snoopay700]

Well i hope it all works out ok for you, i'd hate to hear about an RT having to give up it's valve.

Were you able to find out the correct tap size? I can measure it tonight if you haven't found out what it is yet.

[RehKal]

I haven't had time at work to make a call to AGD to find out the correct size. So, no I haven't been able to.

I would greatly appreciate if you could measure it fo rme.

[wetwrks]

Have you considered sending it in to AGD to let them try and work it over?

[SocialD]

You are in luck! The thread size is 5/16-24 which is a standard size that you should be able to buy at your local Ace Hardware. You also have the option to Helicoil it if it is completely messed up.

Good luck.
-D

BTW, you might want to get a bottom tap too so that you can chase the threads all the way to the bottom of the hole.
