I disassembled my lens to clean up however when I assemble back the lens is not cocking (manually cocking using screwdriver while unmounted), the shaft winds back to original position and the aperture blades bounce back to its original position. Not sure if I didn’t put the pinion and cam in the right position or something else is wrong. Need any expert advice. Thank you very much! I can send a video if needed.
