Need help for TM 1000......I have a leaker!!!! Again!!

Nation,

I thought it odd with the grease as well, I ended up tearing the whole thing apart, cleaned all the grease out of everywhere, and resealed it again. Same result. Took it apart again, and after having Martin on the phone for over 10 minutes, we came to the conclusion it was a valve oring problem. Put brand new ones in, still leaked. Went and put 1 slightly oversized o ring in diameter and thickness. Did the trick, but now, the regulator breathe hole was leaking. Changed all 3 o rings on the regulator, the old ones FELL OFF. They were like stone!!! Got it all back together, and.......SUCCESS!!!!! That was the problem. The o rings that I have in the older kits that I had seemed to be a touch undersized. Charged it up, found one small leak in the Foster fitting, when it leaks down I'll change it out.

Thanks to all that helped on this issue, it's well appreciated.

Yup, as a tuner working on guns near daily been there and done that experiencing some mighty frustrating head scratching moments myself.

Glad you got it figured out.

.... Beautiful finish, and when put air pressure behind it, it held without leaking…....

... came to the conclusion it was a valve oring problem....

Good to know that you fixed it finally. Definitely good learning for me.

I am just curious about the reason for the lack of leakage when you tested the valve externally. Was the under-sized O-ring in place when the test was done ?

Airgunfans,

The valve body and valve itself was tested for leakage, without any o rings. This test assured me that the sealing of the valve itself was proper. When installed with the original spec o rings, it leaked. This told me it was 100% an o ring sealing issue. When I removed the 2 o rings, and replaced them with the one thicker one, it sealed properly. This also confirms that the valve was actually sealing the way it should've.

Yup guys,

Kind of the same way. After I lapped the valve, I took the valve body hooked up to a shop compressor with nylon tubing just a little smaller than the valve diameter, so it was a really tight fit. I slipped the tubing over the valve poppet end, put a small clamp on it. Fired up the compressor to around 50 PSI, and dunked it in a cup of water to detect (or in my case not) any air getting past the valve and seat.

That's all there was to it
