ON CERTAIN TRUCKS EQUIPPED WITH A SAF HOLLAND SIMPLEX FIFTH WHEEL, THE LEVER ARM PIVOT BOLT MAY HAVE BEEN OVER TIGHTENED. AN OVER TIGHTENED PIVOT BOLT CAN DISTORT THE PIVOT BOLT SPACER SLEEVE, WHICH MAY PREVENT THE FIFTH WHEEL LATCH JAW FROM CLOSING AND LATCHING SECURELY AROUND THE TRAILER KING PIN.
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 EQUIPPED WITH BENDIX SR-7 SPRING BRAKE MODULATING VALVES, THE INTERNAL RUBBER CHECK VALVE MAY LEAK CAUSING A DELAY IN THE APPLICATION OF THE SPRING BRAKES TO PARK THE VEHICLE AFTER THE OPERATOR PULLS THE DASH VALVE BUTTON.
ON CERTAIN TRUCKS EQUIPPED WITH PARKER SINGLE CHECK VALVES (SCV) PROVIDED BY BENDIX. THE DEFECT EXISTS IN THE PARKER SCV THAT CONNECTS WITH THE SUPPLY PORT OF THE SR-7 SPRING BRAKE MODULATING VALVE. AFTER PROLONGED USE OF THE PARKER SCV, THE VALVE BODY RETAINER MAY BECOME EXCESSIVELY WORN AND EVENTUALLY BREAK APART. PIECES OF THE PARKER SCV CAN BECOME LODGED INSIDE THE SR-7 SPRING BRAKE MODULATING VALVE, POTENTIALLY CAUSING EITHER LEAKAGE OUT OF THE SR-7 VALVE OR PREVENTING AIR FROM PROPERLY EXHAUSTING FROM THE SR-7 VALVE.
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 TRUCKS, THE FUEL LINE CROSSOVER BRACKET MAY PREMATURELY FAIL AND UNEXPECTEDLY FALL TO THE ROAD. THE LOCATION AND SIZE OF THE BRACKET DRAWS A CONCERN TO THE BRACKET BEING PICKED UP AND THROWN BY THE DRIVE AXLE WHEELS.
ON CERTAIN TRUCKS EQUIPPED WITH ARVINMERITOR SERIES 145 AND 160 REAR DRIVE AXLES. SOME OF THE SPINDLES WERE OVERHEATED DURING THE HEAT TREAT PROCESS WHICH COULD RESULT IN A FRACTURE OF THE SPINDLE.
ON CERTAIN VEHICLES, THE BRAKE CAM TUBES ON THE STEER AND DRIVE AXLES MAY NOT HAVE BEEN GREASED.
ON CERTAIN VEHICLES, THE BRAKE CAM TUBES ON THE STEER AXLE MAY NOT HAVE BEEN GREASED.
ON CERTAIN VEHICLES, THE BRAKE CAM TUBES ON THE STEER AND DRIVE AXLES MAY NOT HAVE BEEN GREASED.
ON CERTAIN VEHICLES. THE BRAKE CAM TUBES ON THE DRIVE AXLE MAY NOT HAVE BEEN GREASED.
ON CERTAIN HEAVY DUTY CLASS 8 TRUCKS EQUIPPED WITH FXL AXLES, THERE IS A POTENTIAL THAT THE DRAGLINK MAY CONTACT THE BRAKE SLACK ADJUSTER DURING FULL WHEEL CUT AND ARTICULATION OF THE CHASSIS.
ON CERTAIN HEAVY DUTY CLASS 8 TRUCKS EQUIPPED WITH ACCURIDE ALUMINUM WHEELS, THE WHEELS WERE NOT PROPERLY PRE-STRESSED. THIS ALLOWS CRACKS TO DEVELOP OVER TIME.
