Do 3.5" drives benefit from recaping?

[Genjoke]

Hi folks.

I got my old Classic and a newly aquired Classic II up for restauration.

✔ Both motherboards are working fine after recaping
✔ One analog board is working after recaping (the other one needs more work)
✔ Internal blue scsi on both
✔ succesfully printed (after almost giving up twice) the eject gear for the floppy drives

I was very happy about the drives finally ejecting, after cleaning, lubing and swapping the desintegrated eject gears.

Nevertheless, I can't get them to read floppies!

I cleaned the head more than once and nothing.

The last step, that comes to my mind, would be recaping them…

Is it worth the trouble? Read/write errors may be caused by failing eletrolytic caps??

Thank you for any advice!

What are the symptoms when it tries to read?

You can look at the zero track alignment resource here: https://tinkerdifferent.com/resources/zero-track-alignment.37/

Also @JDW has a video on recapping a floppy drive:

It just sais the disk is unreadable and offers to format it, which fails. I’ve tested the disks on my g3 beige and they are ok. They are also readable on an USB floppy drive.

I will check those resources , thanx!

Thank you @eric , it was a little fiddly, but

did you follow the zero track alignment document and that fixed the issue ?

I have a few floppy drives that were made worse after i tried servicing them. Perhaps i just need to align the zero track.....

I tried fixing three drives. None would read a disk. I succeded on one of them and lost my patience with the latter two...
