Thanks all for feedbacks il will try again tomorow if i cant undo it then i think il go for the cutting , il keep you all updated whit more pics to come =) , one qustion if i chose to cut , would the fastner still be stuck ? after i cut in the bearing hub ? 

No, cutting off that section of casting and part of the bolt should release it. If you cut along the face of the main hub casting too as you indicated in your pic, there will be no thread left gripping.
