Not sure if posting in these threads are bad or not but I am just tossing out 2 cents or half cent whichever and only to help. But I had a devil of a time getting that thing out. I noticed that the main issue I was having was that I couldn't get the downword pressure to sustain enough as I also pulled upwards. So I took my snap ring pliers over to the vise. Laid them gently on the edge of it. Just to where about a hair of the tip was hanging over. And gently taped on it with a hammer to put a slight bend on the tip of the pliers. And I mean just a hairs length at the end of the pliers. Gave me just enough that when I did apply the downward it had enough to wedge itself underneath giving me the leverage I needed to gently pull upwards.
Hope this helps someone!
