Thanks, guys.
I had totally forgotten about this long lost thread, which must have gone unnoticed by everyone else until now.
My Mk3 was NOS when I bought it; it's still in perfect cosmetic condition. I have done the Krebs mod, and I mounted the chassis in a lead and wood plinth of my own design that weighs a net of ~80-90 lbs. I mounted a 10.5-inch Reed 2A tonearm with an ZYX UNIverse cartridge, and I am very fond of the whole set-up. One of these days, I will have JP Jones install his upgraded chip and re-calibrate it, but right now I don't think it could be beaten, although other high end turntables may sound "different".
But funnily enough, I cannot recall whether I ever did anything about the bearing lubricant. I may have or may not have. The bearing itself could not possibly have had any wear on it, because of the NOS status. Five years is a long time.
