Omega B – Clutch change -> Central pulley new? Yes or no?

Hello guys, I have to change the clutch again with the Omega. I now ask myself whether it is enough to change the back bearing (which is included in the clutch kit) or the complete hydraulic central exit. The back bearing is only plugged on. At the Vectra I only changed the bearing at that time. Since the central exit was usually the same as in the Omega (by the way is the same as in the Omega). The outfeed is expensive, costs alone more than the clutch kit of Lu K or Sachs. It’s clear that the needle bearing also has to be new, but what about the mover? I would, if necessary, then pick up the mover from Topran and put the bearing out of the kit on it, since I have not had any bad experiences with the parts of Topran lately. Especially with our city coach I have never had a failure with the parts of Topran… Greetings
