On the inside part of the left frame, unhook this end of the large spring.

Back on the outer side of the left frame, bend this cotter pin and pull it out of its hole. Put it in bag 9. Don't worry if it breaks, because it is easily replaced.

Pull the entire lever assembly with shaft straight out. Pull it smoothly along the direction of the shaft, possibly using another hand to push the shaft collar off the other end.

Put the collar in bag 9, and set the lever/shaft assembly aside.
