I got the rods and springs out of my Cento forks, by removing the bolt through the link, then removed the buffers, then, with a big screwdriver, levered the rod and spring up, just enough to remove the ball, then there will be no tension on the link, and it can be removed. Once the link is out, the spring and rod can be removed.
I have no idea how I'm going to get them back in though
