Message-ID: Replaced the handle on the toggle valve. Because the split-pin is in an awkward location, I replaced it with a 2-56 x 1/2" allen head screw and a aircraft locking nut. This will make it easier to change next time .... and the diameter of the 2-56 is just about perfect in this application.
