I have 2 case 446 rear ends being made into an articulating 4WD mini tractor. I would like to know the specs on the hydraulic motors that power the rear ends. They are made by TRW ROSS. The spec number on both are MAB24001. The Code numbers are 262 85 and 075 83. One is from an 83 model year 446 and the other from an 85 model year. I specifically need to know the max rated operating pressure, max rated rpms, and the amount of oil requires per one motor revolution in cu./revolution. Thanks for any help that I can receive.
