Fix NEC FD1054 (360k) 5.25 Floppy Drive

This Floppy Drive, but probably also other models, suffer of a quite annoying problem.

The little box in aluminum placed over the head of the Floppy Drive comes off, this happens because the bioadhesive foam rubber that was used to fix the “box” on the head will dry.

This piece of aluminum that at first thing can seem absolutely useless, however it is not, because it is a balancer, without this little piece of aluminum the floppy drive head vibrates and consequently don’t read / write properly.

The replacement of the bioadhesive foam rubber is very simple.

  • Remove the top of the Floppy Drive (3 screws)
  • Look for the little box that are detached and wanders inside the Floppy Drive.
  • Thoroughly clean the remains of the bioadhesive foam rubber inside the box and on the upper side of the head (see photo). Don’t make much pressure on the head.
  • Use another piece of foam rubber with the same thickness (see photo). For this purpose you can use a thousand of way to fix this box, the important thing is that must remain raised and  don’t touch the Floppy Disk (see photo)
  • Fix the foam on both sides with a glue, i suggest a small amount of Bostik or Loctite – Super Attak.
  • Wait for it to dry.
  • Close everything.

    What’s the exact thickness of the new foam (or rather: the exact size of the foam)? Any idea?
