Howdy, haven't been on the site in a few years but I'm trying to replace my lift cylinder o-ring.... I removed the main cylinder (4-bolts to remove the lockout screw and main cylinder, but I can't get the inner cylinder to drop out (to get to the oring, as I understand it)... it won't move past a few inches. I was expecting a little force to get the inner piston to come out, but I can't get it to move more than a few inches either way - (with a softish hammer and punch) Should I use more force or what?

This is where it's at on the table... I'm confused.
