Y50 dial replacement procedures.
…you have to loosen 2 screws on the bottom of the unit. You do not need to remove the screws.
Now, taking a flat head screwdriver pry the bezel, which is the ring around the dial. When removing the bezel, be sure not to bend the tab at the top.
Taking a pliers bend at least 3 of the tabs… …that are around the dial.
Remove the dial from the scale. Be sure to insert the lens with the printing on the outside.
Slide it into place where the old dial was. Now, bend the tabs back around the lens with your pliers.
To reinstall the bezel, make sure you do the top first. The tab should catch at the top and then you can slide the base of the bezel underneath the base around the screws.
Re-tighten both screws down. Your installation is now complete.
