Pohoho 0 Posted May 14, 2013 (edited) This part (called the York I think) keeps popping up and refusing to stay in the groove of the castle gear where it's supposed to go. I have assembled / re-assembled several times but it just keeps popping when you start to move the stem. Anyone with a solution to this problem?

jerkstore 14 Posted May 15, 2013 I think that part is called the yoke. Although the 21J movements in the links below appear to be different, check them out: http://www.repgeek.com/showthread.php?t=37330 http://forums.watchuseek.com/f72/lesson-iv-romoving-date-module-actual-oiling-408354.html If all else fails, just buy a new one for $20.
