How do you take apart the lever part of a DA QR skewer? Duh, I'm not asking how to use a QR.

What I mean is, I'm comparing the more recent DA skewers (like from 7700/9 speed to current) with the older style QR levers from Campagnolo Record or others. With the older stuff, there was an acorn nut that threaded onto the cam part of the lever. (Sometimes a blasted circlip.) Unscrew the acorn nut, along with possibly a small lock washer, and the cam assembly would come out of the housing. You could then clean and grease the cam and reassemble. In fact, you almost had to eventually in order to get smooth high tension on the skewer itself.

With all the newer DA levers, it almost seems like this assembly is a permanent press fit. Is this the case?
