Thanks a lot for all the suggestions on the previous post!!
The weird thing is that I could push the pin from the D shape side but not from the right side.
I was looking for something to push from the end to align the handle, the plier and the two washers. Then I remember I had a stepper motor ( from an old ender 3) and the shaft was the exact size as the pin.
So I used the motor to align everything and push it out with the correct pin.
Well that was definitely a wild card that work perfectly.
