I went over how to repair jammed up drives in my mac repair seminar at VCFE, and repaired an 800K drive there - don't know if anyone videotaped it or not. I could definitely do it again at the next workshop, if anyone is interested. Can go over 400K and 800K drives. It boils down to knowing how to take the mechanism apart and remove the metal loading part. Then it's just straightforward dissolving of the old grease with your favorite solvent, and relubricating with something suitable, such as lithium grease or silicone lubricant. -Ian On Fri, Apr 29, 2016 at 12:01 PM, william degnan via vcf-midatlantic <vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:
Just an FYI, these two books : Dead Mac Scrolls ( http://www.amazon.com/Dead-Mac-Scrolls-MacIntosh-Thousands/dp/0940235250) and Mac Classic & Se: Repair and Upgrade Secrets ( http://www.amazon.com/Mac-Classic-Se-Upgrade-Secrets/dp/1566090229) Are extremely useful books for this type of repair. I use them both a lot on all of the unibody Macs that I'm fixing.
Details on what parts drive what in ways that are fairly simple to understand (I just need the guidance as to what part to replace as well... not an EE... I can solder well enough for any sort of repair on these :-) )
I've also got some things for stuck drives (and sources for the gear that can go as well).

Thank you very much. I am also interested in more information about repairing stuck drives.
