Next came cleaning up the pump itself. I drained the old oil out, which was black. The took it apart.
I got the rotor housing out. The case around it was full of brown sludge from dust and rust mixed in the old oil. So I cleaned that out and scrubbed everything.
Above you can see one of the actual rotors (it is a two-stage pump).
I put it all back together and need to get some more oil to add, then fire it up and see if it works.
