What was found
(CAN) DURING INVESTIGATION OF HYDRAULIC FLUID LOSS THE MAIN RETURN LINE FOR THE HYDRAULIC RESERVOIR WAS FOUND TO BE LEAKING A BEND RADIUS. THE TSN FOR THE PART IS UNKNOWN AT THIS TIME BUT IT DOES HAVE A DATE OF MAUNFACTURE 09/26/03 MARKED ON IT. IT APPEARS THAT THE CAUSE OF THE CRACK MAY HAVE BEEN IMPROPER INSTALLATION AS IT IS VERY DIFFICULT TO REMOVE/INSTALL THE LINE.
