If the trigger on the T-bolt is anything like the Disc or the Wolverine, it is held in place with one smallbolt. After you pull the main T-bolt/striker from the breech, remove the stock. Take the bolt out that holds the timney trigger in place. What I do is go to the kitchen sink and get some hot water running. Put a few drops of some dish soap all over it and then hit it with the sink spray attachment driving the soap all through it and then rinsing it clean in the hot water. After that I take some brake cleaner, or carburetor cleaner (NAPA brand). Attach the straw to the cleaner that comes with it. Then OUTSIDE, start to shoot that cleaner into all the parts of the trigger you can reach and see (watch so that stuff does not get into your eyes). This will drive any gunk, dust, and most of all dry out any water that is in there.

After that I go to the air compressor and with a pressure attachment, blow forced air in and through the trigger assembly. This again is to insure that the trigger is clean and now very dry. After that a few drops of gun oil into the back side works (a little goes a long way). Wipe the outside off with the oil patch and put it back.
