Here are a few more details of this project.
The nut showing the internal threads. They are 0.25 mm pitch.
The pliers I made from a regular plier that would hold the cap at an angle. I never did see the JDeere tool. I just made it to look like what they described. The pliers were required to remove the old caps before machining. They worked like crap. A rubber sleeve might have improved them. A small vice grip worked better but mangled the caps.
