Quick take: Fixing an interesting Okidata GM-3315BU 5.25" floppy drive

I'm working on an old computer which uses two of these quarter height drives. (Or perhaps they are more like 2/3rd heigh drives.) They are 360k double sided Shugart interface floppy drives, compatible with the IBM PC and compatibles. (And many other machines that use this interface.) In this video I'll give you a quick demo of how these drives work and I'll revive one of them which wasn't working at all. The machine that had these drives was made in 1985, so this interesting design is at least that old. Also, in the future I'll make a video showing off the the interesting machine these came out of.
