First hand experience with 2010 PS is limited as PS was still sort of a novelty option back then. Also most 2010's, in particular diesels have been scraped. There is likely some info in the factory service manual at 1-800-522-7448. Here is a link to the JD web page parts section where a look at the PS internals and part #'s can be had. The PS unit and hydraulic pump appear to have been used only on the 2010. Some equipment does share common pumps and PS with several tractors, combines, forage harvesters, industrial equipment etc.
