If you are using Reese 16K hitch # RP30047 or 30866 then follow these instructions for lubricating the hitch:

Lubricate the skid plate surface of the hitch with automotive type chassis grease, 5th wheel trailer grease # L10321, or use a plastic lube plate to provide a lubricated surface. On # RP30047 use engine oil to lubricate pivot points of moving parts within the hitch.

For hitch # RP30047 or 30866, plastic lube plate # RP83002 can be used to avoid messy grease. The plastic lube plate must not exceed 3/16 of an inch in thickness to ensure the hitch will operate properly. Lube plates must be 10 inches in diameter or larger to properly distribute king pin weight.

For the Revolution pin box you should frequently lubricate the wedge surfaces, back side of the king pin, and the skid plate surface again with grease such as # L10321.

For the Revolution arm you can apply lithium grease, # L11350, to the bearing surfaces. I have included a picture that points out where to apply the grease.
