No one else has answered…I don’t own a C&P pilot, but I think the cores of Pilots have a tab or two pinched out that the trucks go over…there is a slot in the truck for them to fit into. Ideally the trucks do not rotate independently of the roller, they should roll with the roller. This one reason the trucks should be the same size as the roller. Thus the trucks should not be lubricated. Oil on the rails causes all sorts of inking/printing problems.
Where the roller cores fit into the roller hooks is a different matter. Those should be lubricated. 30 weight non-detergent motor oil seems to be the accepted product. It’s what I use on my presses.
