There is a more subtle issue of the effects of the washer (140) either missing or on the wrong side. This would not jump out on a visual inspection like missing locking means would.
Not discernible from the drawing but appears that the shoulder the washer sits on is probably just a bit larger than the hole in the hinge bracket (90).
did you magnify the photo?
If you haven't, please do. I see the arrangement in the photo as indicated in the drawing.
