Ok. Wanted to get back to this. I have dug, and dug.... I have a hydraulic shop that I work with all the time. They are the best people I have ever found at what they do. They and I neither one can identify this pump. Nor the maker, but we are almost 100% certain that it is NOT an EATON pump. Now, it may be that the maker of the pump was bought out by EATON, but it wasn't made by them. If by a long shot it was, they and I neither one have ever seen an EATON pump like that. The numbers you are using on the housing are nothing more than casting numbers. They'll get you nowhere. There should be, somewhere, a number stamped, not cast, in the housing.
Now, we also aren't sure if this is an odd gear pump, or what. But my hydraulics guys and I agree that it looks like a vane pump.
As far as direction of rotation, put your hand over the suction port and turn the pump. When you feel it suck, that's the direction it turns. May have to put oil in it to seal the pump enough to suck turning it by hand.
If you want to know more about this pump, we recommend you take it apart. Not sure if this info helps, but it's all I can come up with without numbers and seeing the inside.
