If you are attempting to service the bearing well on a Thorens in the14X or 16X line, and the drive platter will not lift out, you need to remove the bottom of the turntable (just four screws, one at each foot) and then find the clip next to the bearing well that is pictured above. Fully unscrew the screw which also holds a ground wire in place. Keep track of the screw. Next, gently pry the clip so it moves in the slots you see pictured at each side. That movement of the clip in the direction away from the bearing well, will release the platter so it can be serviced. Reverse the procedure when finished.
