Repairing Daydate Permanent link pin

[tothemoon]

One of the permanent links on my Rolex day-date (5-digit) gets stuck (doesn't rotate), unless I force it to move with my finger. See photo. I believe the pin inside got bent so it doesn't turn smoothly anymore. I assume the pin inside needs to be replaced.

Does anyone know how to get the inside pin out of the link? I hear you'd have to drill holes on the side of the links, get the pin out, and basically re-solder a new gold pin in place. Are drilling holes on the side required or is there a way to do this without drilling holes?
