How do I replace this pivot point?

Hi,

VPI have sent me a replacement pivot point, and I can't figure how to do the replacement. I found a video on their YouTube channel that says to loosen the allen screw on the damping fluid cup, but mine doesn't have one. I tried gently turning the cup, figuring it might be screwed in, but I don't want to force it.

Any ideas?
