The hazard

THE CLAMP PLATES BETWEEN THE DRIVE SHAFT AND CARRIER YOKE COULD CRACK. A BROKEN CLAMP PLATE WOULD RESULT IN THE YOKE FLYING OFF AT THE DETACHED POINT. THIS COULD CAUSE INJURY FROM FLYING FRAGMENTS TO PERSONS IN THE VICINITY. ALSO, THE DETACHED INNER SHAFT COULD INTERFERE WITH THE BRAKE SYSTEM AIR SUPPLY HOSES AND EVEN THE TRACTOR TIRES. THIS COULD CAUSE LOSS OF VEHICLE CONTROL AND A POSSIBLE CRASH. CORRECTION: NEW CLAMPING PLATES AND CAP SCREWS WILL BE INSTALLED AS REQUIRED. NOTE: NO VEHICLES IN CANADA.
