Oil pump intermediate shaft breaking

Look very closely at the rotors, there should be a witness mark, divot, or some blemish on the gears, where it swallowed a chunk., 2 broken shafts, 2 divots.
Take the used oil pick-up over to the bench, and bang it really hard on the bench, numerous times, pound it, shake it, listen for debris, anything at all come out?

That's what I would do, jmo.

Then buy a new pick-up .

Be aware, some outer pump rotors have one chamfer edge, and if installed upside-down, may bind and jam the rotors.
Make sure the pump turns before install.
You know how I know . That was one shaft .
