Here we go again. When standing in front of the tractor the engine turns clockwise. Hydraulic pump rotation is determined by having the shaft point up toward you if you are holding the pump in your hands. Now I think you are talking gear pumps, am I correct. Is the belley of the pump as it is known up ( above the drive shaft) or down below the drive shaft O. K. if it can be mounted either way, then is the suction port on the right side or left side of the tractor as you sit on the seat? If the suction port is on the right side, pump belley down you need a counterclockwise pump. If the belley is up and the suction port is on the right you need a clockwise rotation pump. Remember the oil goes around the outside of the gears as the pump runs. Post a U. S. mail address and I will send you some good information. Also remember all pumps are rated on theoretical pump output.If you do the math cubic inches per revolutions time revolutions divided by 231, they will not pump that much as no pump is 100% effecinet.
