Yes. Loosen the large locknut and tighten or loosen the circular nut, the item with two slots, that it surrounds. I had a tool made out of flat stock with a nut welded to one edge which goes in the slots and is turned with a socket. Sure makes it easy. The thing to do is to remove the entire unit and clean it up on a wire wheel, coat it liberally in anti-sieze compound, then reassemble.
