O.k. , accessory housing off and oil pump= out. The picture is showing how the oil pump came out. Rest of the story.=
Found the missing pump rotor in a parts= box, and put the engine back together.
Now I am scared of myself.
 
Sometimes this is what we need not to get= too confident in ourselves.
 
FWIW.
