ON CERTAIN TRUCKS EQUIPPED WITH ASET AC MODEL ENGINES, THE ENGINE AS CONFIGURED WITH AN EXTERNAL EXHAUST GAS RECIRCULATION SYSTEM MAKES SERVICING THE FUEL INJECTION LINES DIFFICULT WHEN USING TRADITIONAL TOOLS. THEREFORE, IT IS POSSIBLE FOR FUEL LEAKS TO DEVELOP WHEN REMOVING AND INSTALLING THE FUEL INJECTION LINES.
ON CERTAIN TRUCKS, A LEAK IN THE ASET AC FUEL INJECTION LINE MAY SPRAY FUEL ON THE EXHAUST GAS RECIRCULATION PIPES THAT CARRY HOT EXHAUST GASES .
ON CERTAIN HEAVY DUTY CLASS 8 DIESEL TRUCKS EQUIPPED WITH ASET AC ENGINES, THE LOCATION OF THE FUEL INLET HOSE MAY RESULT IN OVERHEATING OR ABRASION OF THE HOSE, WHICH MAY LEAD TO A PREMATURE FAILURE.
ON CERTAIN TRUCK CHASSIS, THE STEERING GEAR MOUNTING BOLTS WERE MADE OF INCONSISTENT BOLT MATERIAL, WHICH HAS LED TO BOLT FAILURES. THIS INCONSISTENT BOLT MATERIAL CONDITION COULD RESULT IN A FAILURE OF A STEERING GEAR MOUNTING BOLTS. THE STEERING GEAR IS MOUNTED TO THE VEHICLE'S FRAME WITH THREE BOLTS.
ON CERTAIN CHASSIS BUILT WITH LNG ENGINES, THE NEXGEN LNG TANK'S PRIMARY AND SECONDARY RELIEF VALVES COULD FAIL TO OPEN AND RELIEVE TANK PRESSURE.
ON CERTAIN CHASSIS EQUIPPED WITH DANA STEERING AXLE ASSEMBLIES. THESE AXLES ARE BUILT WITH AN INTEGRAL KNUCKLE AND STEERING ARM. THE STEERING ARM COULD HAVE LONGITUDINAL CRACKS.
CERTAIN HEAVY DUTY VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS." IMPROPER SEATING OF THE CHECK VALVE RETAINER IN THE BRASS FITTING HOUSING HAS OCCURRED. IT IS POSSIBLE FOR THE AIR BRAKE SYSTEM PRESSURE TO PUSH THE CHECK VALVE INTERNAL PARTS INTO THE PRIMARY SYSTEM RESERVOIR AND A VEHICLE OPERATOR WOULD NOT KNOW THAT THIS HAS HAPPENED.
