It’s not an imbus hole in the center. Just a hole, not possible to get the cap of. Tried unscrewing the bolt and hammering it out but it’s stuck… help me out!

Use a c clamp and a 10 mm socket.
In my experience, there’s a good chance you’ll have to drill out the cotter pins. It can be done with an electric hand drill but if you can get access to a drill press, it’ll be much, much easier. Use low RPMs, lots of oil, and a metal-specific drill bit.
Definitely don’t hammer the cotter pins. You need to press them. The damage may already be done, but hammering tends to make them bulge so they’re even more stuck!
You’ll need a baguette, a cigarette and an espresso.
