Alfa Romeo Group A center lock hub part 2 – Safety pin, Nut, Drive pins
This is the second part of the project, where I am showing you how three more parts are crated. First is the locking nut. It is one of the most important components here, it is used to mount and secure the wheel to the hub. Second is the safety pin. It’s role is to prevent the wheel nut of falling of, in case of it coming undone. Third and last is the drive pins. They are used to transmit the drive torque or the braking momentum to the wheels. They fit in corresponding bores in the center section of the wheel.
