^^^ ^^^^^^^^^^^^^
Are you sure it was on the head assembly ?
If so this would mean that the internal areas of the drive were
being compromised from leaking bearings, true ?
Having had one of these older drives, I remember having to
twist the drive sharply to get it to spin again. And it ran
well for many months afterward, to my great surprise. ;-)
