What was found
(CAN) WHILE REPLACING O-RINGS AND BACK-UP SEALS IN SOME HYDRAULIC ACTUATORS, FOUND SOME OF NEW BACK-UP SEALS DEFECTIVE. THE CHAMFERED EDGE OF THE SEAL IS TO SHORT WHICH IN TURN CAUSED THE EDGE TO DAMAGE THE O-RING. IT SEEMS TO ACT AS A KNIFE EDGE. ALL SEALS IN A BATCH WERE NOT FOUND LIKE THIS, ONLY A FEW. THAT IS WHY SOME OF OUR ACTUATORS HAVE BEEN LEAKING DUE TO THE BACK-UP SEAL CUTTING THE O-RING. WILL BE SENDING A REPORT AND PICTURES TO THE VENDOR.
