Picked up this Teflon lube sample gratis at the National Association of Manufacturers show at
McCormick Place Convention Expo, Chicago. Medical-type syringe and needle may be helpful.
Did use Solder Seal Gunk brand L508 PTFE (generic Teflon) Lubricant in a spray can, available at
an unusually complete auto parts store (noticed that Solder Seal Gunk Liquid Wrench L512 dry
film PTFE Cerflon (Teflon) Lube is listed in their catalog, unevaluated). The lube is sprayed into
the cap and transferred with an end of a screwdriver tip or Q-tip. The DuPont / Finish Line
formulation is better by leaving a thin white coating of Teflon that seems to adhere to metal, yet not
leaving an oily residue that attracts dust.
Do NOT recommend using an oil (sewing machine, 3-in-1), synthetic grease lube (white), silicone
lube or spray, or penetrating solvents like WD-40.
3) Lighted work table with comfortable Herman-Miller Aeron chair, with 50 watt quartz halogen
high intensity lamp. Highly recommend a high intensity flashlight to see black hidden parts of
mechanism. Use a Makita ML902 flashlight 9.6v Ni-Cd with ratcheting right angle head, or
equivalent. Perhaps a Petzl Tikka forehead-strapped LED flashlight will work too.
4) Plastic (pink) antistatic foam pad, 1 ft x 18" x 1/2" thick, preferably grounded with 2 Meg-ohm
resistor.
5) Cheseborough-Ponds cotton Q-tips or TexWipe foam swabs and aqueous lens cleaner, isopropyl
alcohol or Everclear liquor 190 proof ethanol. Kimberly-Clark Chemwipe tissues.
6) Antistatic bag, 12" x 14" to hold circuit board
7) receptacles to conveniently organize and secure tiny screws, recommend a 6-pack of empty vials
(tubs) with intact foil covers. Suggest Kraft Crystal Light diet beverage powder concentrate empty
tubs, UPC 043000-950517, or equivalent. Don't drop screws on the floor as the tiny black ones will
be extremely hard-to-find (and extremely hard-to-buy to replace them).
8) About 2 hours of quality time, known-good test computer with NikonScan v3.1 application (or
equivalent) installed, data interface and data cable, AC power cord for Nikon and grounded power
strip.
9) 8 1/2" x 11" notepad and PaperMate Write Bros pen with cap
III. Disassembly and maintenance service procedure
(this example is for Nikon Coolscan III, model LS-30 which has two MD-50 pin SCSI jacks, 1999
vintage)
0) remove all AC power and signal cables.
