Best thing to do is to soak it penetrant for a few days (if you're not in a hurry).
If you have 2 stout screwdrivers, put 1 on either side of the head; you might be able to pry it out.
I didnt have too good of luck on my D17sIV, so I made a split "collet" from a socket-head capscrew that fits over the head of the pin. A collar on the shank pushed the split halves back together, capturing the head of the pin.
Made up a not-so-heavy slide hammer that screwed onto the "collet" and with a few good yanks, pulled the pin out. Worked good.
If you want to borrow it, just cover the shipping and I can send it to you.
