The few that I have done on other equipment, I used my flat end round steel punch set, finding on that just fits the hole. On some they will only go one way in and out and even trickier are the dual pin set up where there is one roll pin inside the other. For those you need to drive the inside pin out first.
Dennis is the expert on our tractor, so wait for him to give the correct answer.
PS get a few spares...well at least for me...I usually loose one when I hit my fingers on the re-install.
