I can add a pic from the instructions if need be, but I assume you have that. The deal is the 5mm screw, that is replaced with the large 6mm, screws into a specialized screw that is 6mm and way longer. You are removing that one and replacing it with just the one larger screw that is in your hand. In other words, the small screw in your hand is replaced by the large screw in your hand.
To remove the original large screw use a pair of channel lock pliers, there is no other tool for the job, the "head" of the bolt is a round cylinder that is drilled and tapped for the 5mm screw that is in your hand. You have to drop the skid plate in order for access to get the pliers on the original large bolt head.
I can't sleep right now, so I'll add a pic of the specialized screw you are to remove....
Edit: I was wrong, the specialized head has a provision for an allen wrench. You should be able to remove it without moving the skid plate. I guess if I had a bike lift instead of working on the bike laying down I would have seen that when I installed my water pump guard
