RT Classic Help

[Poon985]

I just bought an RT Classic off of E-Bay and was told it has a small leak out of the back of the valve. I gassed it up to check it out and found a large leak out of the rail. After some digging I found a missing O-Ring on the frame gas through bolt, I have a rebuild kit on order but couldn't wait that long so I matched it at the hardware store. Gassed it up to find it leaking bad down the barrel, oiled everything I could find and it seemed to work. I tried to take the valve out and the rear gas through bolt seemed stuck, I took the rail off and the middle o-ring on the gas through bolt was half pushed through the rail, I switched them around so a stock o-ring was in it's place and the same thing. I have had a 68 classic, but the RT is new to me and don't really even know how it is supposed to act. Any advice would be great.

If the top O-ring on the banjo is sealing with enough clearance, you could try shimming up the banjo on the bottom. IDK with what. Maybe a grub screw in the frame? Or shim it from the top by putting something in the valve? Anyway, sounds like a rare problem. You're not over-tightening the banjo, are you? It's a spool seal, it doesn't need to be screwed in super tight to seal.

I am tightening it as much as I can by hand, like I would have with my 68 Classic, I am working this weekend, so I'll have to mess with it probably Sunday. It was shooting fine for awhile the way I had it then the o-ring started to push through and got a small leak, hopefully it is just dried out o-rings and the new ones will solve the problem.
