I am in the process of rebuilding yet another model A hub, but I have a curious question. Does the clutch/brake assembly need a thin oil? See the image of part I am referring to. I have rebuilt a number of these and have lubricated all the parts with grease except this one. The other day I saw someone on the net oiling the part pictured with thin oil. Not sure if I should add this to the “don’t believe everything on the internet” column or if I should start lubricating. Inquiring minds need to know.
