Advice needed to remove MB hood star

[Mervyn]

I just bought myself a hood star kit and was attempting to replace my current one when it occured to me that there must be something I do not know. I turned the cylindrical sleeve covering the spring, and managed to loosen the assembly, but it still would not come out. Should the sleeve turn outside the spring mount (that is, expanding), or should the sleeve be turned into the mount (constricting)?

Or am I on the wrong track altogether?

Any advice is greatly appreciated, thanks.
