Amiga HD floppy drive repair - Chinon FB-357A

This is just a quick and simple repair of the Chinon FB-357A high density floppy disk drive. This drive was inside an Amiga 4000 that I was working on. It had intermittent problems with the 'disk in drive'-detection. I also cleaned the heads with a little bit of alcohol while I was at it, which is not included in the video.
