Case part number is L17373, but Case shows it not available anymore. It does say a pump with the number A139693, had the same flow, but in the description, it says something about the end, the nothing else... Case doesn't even show it, when I did part number search.
Could be a toughy to find, other than a bone yard. Even the rebuild kit doesn't some up anywhere on Google search.
Here is a link to a fellow that has lots of NOS Case parts. He says in his home page, if he doesn't have it, he may be able to find it.
