is the position "05" a spring holding the bearing? position "08" must be O-ring ...
did you took the cylinder unit away from the headstock already?
I guess, there is nothing attached "to the upper side of the spindle". Cylinder is pushing the tool clamp rod through a special rotary unit as usual.

Thanks for the advises however we have figured it out that we have to move the tool clamp cylinder unit on the spindle a bit upwards to be able to lose the screws that are holding the shaft against remove...
and noticed that the rotary connection units bearing needs to be replaced...
the service guys told its not replaceable... i think ill just buy a new unit and when replaced ill check inside..
i wuld not be surprised if it wuld be a replaceable design, just becouse of my bad experiences of my official Hungaryan dealer.. ): i could say a lot of bad experiences in programming help and machine reparing aswell.
