Teac FD-55GFR 5.25" floppy drive - test-drb@ccmp.vtda.org

10 May 1999

Careful with that grease!  Vaseline is likely to make some plastic alloys
soft, as it contains solvents for some of them.  The clear grease most often
used in lubricating plastic gears, bushings, etc, is called "lithium grease"
and is available at most wholesale outlets which sell screws, nuts, bolts,
etc. by the box.

I have, by the way, found that a box of 100 of some of the more common
screws found in electronics is a really worthwhile investment and saves
money in the long run.  This is especially true of metric sizes.  Here in
Denver, it's the rule rather than the exception that hardware and car parts
stores sell both metric nuts and bolts, yet it's unusual to have bolts and
nuts of the same size as marked on the blister pack actually fit.  I don't
know why this is, but it's a real pain in the gluteus maximus!  I've never
had this result at Fasteners Inc.  I guess that's why I'd rather buy the
small stuff by the box there rather than the handful at the hardware store.

The C-clip should be a tight fit on the spindle. If it can move relative
to the spindle, then it's too loose. It might be worth taking it off and
either replacing it or squeezing it slightly.

I am strongly of the opinion that if something is assembled with glue
then it was designed incorrectly :-). And I would certainly never put
glue on something that I might want to take apart later.

  of use to someone in future?)
