@@johnw391 correct, but thinking about it now you should be able to remove the index rod, remove the shell plate, undo the 2 screws holding the retainer plate at the bottom and the drive bolt should come out then.
I,m a 55 year old American who speaks native English, I'm able to understand you English pretty well and thank you for your informative videos. I don't consider myself the avg. Joe I'm world traveled and able to survive in just about any enviroment I'm inserted into. Tagalog was honestly the most difficulty for me because many words have no English equivalent and it's a bit strange sentence structure the common Filipino uses but even the not so good engrish (asian-english) speakers I could communicate with. Meh sour 🍇 keep sharing that knowledge.
