Ignition switch, Vento? Adapter sleeve?

I wanted to replace the electrical part of the ignition switch today.

I looked at the instructions, but I'm not quite clear about the adapter sleeve that I need to remove.
Where exactly is it?
I've already disassembled everything today... but how can I pull them forward?

I could have just used a puller, but I was too unsure whether it would fit properly.

I did it the way described in the post.

It took me a while to realize that using pliers to support the puller would be a good idea...

I'm familiar with the instructions, thank you.

There used to be a tutorial with pictures online, but I can't find it anymore.
