The second in our videos trying to get this gun into some semblance of order. We put it over the Chronograph to see what, if any difference has been made by recent tinkering's
That was a brush that was put in the air cylinder to prevent pinging sound when firing. It shouldn't be to hard to clean to clean the valve housing and the cylinder should be fine again. No permanent damage done. Just check that the transfer port is not obstructed. The green on the valve housing means that it has been filled with moist air. Use silicone grease whenever you mount a part, it prevents parts from binding. Never use mineral oil based products in your PCP.
I’m an AT44 nut for ten years now and never have I seen plastic debris in a cylinder, very odd. Clean it out, and degrease the cylinder then reassemble, as long as the valve seat and stem orings aren’t damaged all should work well. I stop removing cylinder and filled on the rifle, which minimized leaks down the road. With a good regulator and pellet these rifle can be tack drivers.
Bryan thanks. we have it sorted now thank heavens. The debris was the remains of the brush like device in the cylinder that helps prevent that awful ringing noise when you fire. Our video entitled AT4410 Success! details the fix Many thanks for your comment.
