Governor driven hydraulic pump

[grampsh1]

Is the pump used on a John Deere 70 the same as on a John Deere AR governor driven

I don't know about the AR pump, but I do know that they changed the oil line fit-up as the models progressed. The pump might bolt to the governor case, but the lines might not fit the pump. A search of parts numbers will tell the story.
