Checking rotating direction of shuttle race assy: Align needle with the right edge (B) of cut portion (A). SECTION 2 - 15 PAGE 4 Checking backlash of shuttle shaft gear and lower shaft gear: 1. Remove bobbin case, shuttle cover, and shuttle hook. 2. Turning hand wheel, rotate shuttle driver (1) and locate the point of minimum backlash. 3. Check if the backlash is approximately zero at this point.
