How to extract the live tool gear

Hi folks, nice to be here (not for this reason but you know what i mean), we have a linx 220lm, and like the title says, it has live tool and i cant remove the helicoidal gear that goes in the shaft in the middle of the tool changer. I attached a photo so you can understand me better, english is not my 1st language. Thanks in advance.
I guess i could try to extract it like a bearing, but i dont know if it has an opressor or something. Or maybe i just hace to unscrew the "nut" that its behind it? I dont wanna mess with anything, so i will wait.

You have taken it apart wrong.

Use the service manual for the rear mounted live tool drive of a Puma 240m, posted in the service manual thread on this forum.

I will look into that, but it makes totally sense, thank you so much.
