I do think you are correct that the center of the 17mm nut I tightened could be held with an allen key or a hexagonal socket, but I did it the way explained above.


I heald the part circled and pointed to with a 13mm wrench. It is a round piece with two flat sides which were easy to hold on to

While spinning this piece with a 17mm socket. Worked well until it was flush with the cover which has the 14 pronges. Definently didnt make it to the reccomended 40nm of torque
