Olympus PEN E-P1 disassembly and workaround for broken IBIS gears

Documenting the disassembly of an Olympus PEN E-P1 from 2010, and explaining a workaround for broken IBIS cogwheels resulting in a misaligned sensor. This doesn't fix the red flashing IS indicator, but gets the sensor centered to avoid vignetting. I hope this helps you understand if/why your PEN has that problem, and decide whether you want to tackle the repair yourself. This is my first time doing voiceover in a video, please excuse my somewhat rusty english. I'm generally not a great speaker. Inspired by    • Olympus E-PM2 Camera IBIS Repair   where Markus Koch fixed slipping cogwheels on an E-PM2.
