What was found

(CAN) HYDRAULIC BELT WAS STARTING TO DEBOND NEAR THE DIRECTION OF ROTATION ARROW NEAR THE BONDED JOINT. THE TTSN OF THE BELT BY THE MANUFACTURE IS 600 HOURS. WE HAVE FOUND THAT THE OCCURRENCE OF DEBONDING IS HAPPENING TOO OFTEN, SO OUR INSPECTION OF THE BELT IS MORE OFTEN SINCE WE DO NOT WANT A BELT FAILURE.
