I select the center element of the wheel en press ‘cursor to selected’ …but nothing happens…

I have tried to change pivot points and transformation orientation…but nothing changes…

Maybe i did something in wrong in edit mode…?

Im in 2.8 btw

Where is the origin of the part you selected? That’s where the 3D cursor tries to go. Try setting the origin (F3 -> set origin) and select origin to geometry and then move the 3D cursor to selected
