Oh, I wouldn't take out anything that would require precision realignment. (I would certainly carefully read the entire maintenance manual before attempting to lighten it by removing things.) But some could come out - e.g. if the spindle drive motor uses a drive belt (many do), that would therefore be safe to take out. And the power supplies - you might want them out anyway, to recondition the caps, and check them out. Etc, etc. Noel
