![Apple 400k Floppy Drive Lube Repair [1984 Macintosh]](https://i.ytimg.com/vi/Se10T6gPl-c/hqdefault.jpg "Apple 400k Floppy Drive Lube Repair [1984 Macintosh]
Lubrication is the most common repair for the 400k floppy drive (OA-D34V) used in the Macintosh 128k and Lisa 2 in 1984, as well as the 512k and Macintosh XL in 1985. My video shows what you need to know.
☝️ If my video helped fix your 400k drive, I would appreciate your visiting my iFixit page to click the blue Give the author +30 points! button here: https://bit.ly/2FTBHiM

27:18 Closing Thoughts
📝 NOTE: This video does not cover all possible problems that could be wrong with your single-sided 400k floppy drive. The lubrication repair shown is usually sufficient to fix most 400k drives because hardened grease has prevents key mechanical parts from moving. Also note the later Macintosh 512Ke and Plus (1986) have 800k floppy drives which are not covered by this video guide (drive lubrication points are different).
