I can tell you what has worked well for me IFFFFFFF you can get to it okay. We have used a vibrating air hammer with a big flat blunt punch end and they pushed n vibrated right outa there slicker n a whistle. In the days before that we heated the outer circle in hopes the heat would expand it away from the center pin and got em out that way eventually, but you have the nifty little puller, I use it and apply heat in the outer edges n torque it down a bit n heat more n torque again slowlyyyyyyy n heat n torque till she starts out. A new pin n bushing feels so nice n tight once its all rebuilt. How many of those old ones where you can move the handle like a foot either way lol.
