No need for any lubricant on the hitch plate with a Revolution. You can use a little oil/grease on the kingpin and wedge sides for ease of hookup if you like.
I take my Sidewinder apart once a year or so and grease all the bearing surfaces with Lucas Red-n-Tacky.
With your Revolution you just take off the castle nut on the bottom to lower the hitch and regrease the bearing/spindle. Take a look at maint doc on the Lippert site. Also some YouTube videos out there.
