Take the pliers to it again, try it with the pliers parallel to the yoyo. Grip it, and gently rock the pliers right and left. Don’t just pull straight up. Rock right and left with a gentle pull up. You’ll feel it coming loose. Once it seems loose enough, then pull up.
I got it out by advice from a previous thread I found that had the same problem. I put it in the freezer for a few minutes and I was able to take the bearing out. One more question now, the KK bearing is inside now, but it kind of makes a dull noise. I can hear the bearing a bit. Any comments on that?
