VEHICLE DESCRIPTION: HEAVY DUTY CLASS 8 TRUCKS EQUIPPED WITH FONTAINE FIFTH WHEEL ASSEMBLIES. THE FIFTH WHEEL MOUNTING PLATES CAN CRACK. Remedy: DEALERS WILL INSPECT AND REPLACE THE MOUNTING PLATES THAT ARE CRACKED.
THE ENGINE COOLING FAN BLADES MAY BREAK DUE TO INADEQUATE BLADE STRENGTH AROUND THE RIVETS THAT ATTACH THE BLADES TO THE FAN SPIDER. Remedy: AN IMPROVED FAN WILL BE INSTALLED ON THESE VEHICLES.
FUEL INJECTION SYSTEM RECONFIGURATION TO COMPLY WITH ENGINE EMISSION STANDARDS CAUSE HIGHER ENGINE VIBRATION LEVELS WHICH LEAD TO EARLY WEAR AND COMPLETE FAILURE OF THE SECONDARY THROTTLE RETURN MECHANISM. Remedy: A NEW PRODUCTION SECONDARY THROTTLE RETURN SYSTEM CONFIGURATION WILL BE INSTALLED.
THE CARRIER YOKE BOLTS WERE MANUFACTURED WITH WORN ROLLING THREAD DIES, CAUSING STRESS CONCENTRATIONS WHICH CAUSED CRACKS DURING THE QUENCHING PROCESS. Remedy: REPLACE THE CARRIER YOKE BOLTS.
THE DRIVESHAFT CENTER BEARING SUPPORT BRACKET CAN CRACK AND BREAK. Remedy: DEALERS WILL REPLACE THE CENTER BEARING HANGER BRACKET.
AIR SYSTEM BLOCKAGE IN THE AIR DRYER OCCURS DEGRADING THE MOISTURE REMOVING CAPABILITIES OF THE DRYER WHEN THE VEHICLE IS OPERATED IN A COLD ENVIRONMENT AND MOISTURE ACCUMULATES AND FREEZES IN THE AIR DRYER OR IN THE LINE BETWEEN THE DRYER AND THE AIR SYSTEM RESERVOIR. THE AIR DRYER CAN BECOME OVERPRESSURIZED CAUSING THE AIR DRYER CARTRIDGE TO SEPARATE FROM THE MOUNTING BASE. Remedy: DEALERS WILL EQUIP AIR SYSTEMS WITH A PRESSURE RELIEF VALVE TO BE LOCATED BETWEEN THE COMPRESSOR AND THE AIR DRYER. THIS PRESSURE RELIEF VALVE IS INTENDED TO VENT IF EXCESSIVE PRESSURE DEVELOPS IN THE AIR DRYER.
