Hello All, I have a Beogram 4002 that the "bearing needle' (the service manual description for part #37)  that attaches the hinge to the back of the dust cover keeps falling out. The "bearing needle" is the chrome cylinder pin you see when you look at the black metal back piece from the left or right sides. I have been polishing the dust cover and just about lost this piece. I know there is a small screw that is on the back piece that looks like it should tighten down to hold the bearing needle in place, but I cannot seem to make it any tighter than it already is. Any suggestions would be appreciated. John
