FOUR COMPRESSION BACKPLATE RETAINING FASTENERS ON THE TURBO-CHARGER WERE TORQUED ONLY HAND TIGHT. THIS ALLOWS THE FASTENERS TO LOOSEN, AND CAUSES OIL TO LEAK INTO THE COMPRESSOR AIR SIDE OF THE TURBO-CHARGER WHICH, WHEN COUPLED WITH THE HEAT PRECIPITATED BY THE COMPRESSOR AND THE MIXING ACTION OF THE COMPRESSOR WHEEL, CAN RESULT IN AN AIR/OIL MIXTURE THAT FUELS THE ENGINE.

Consequence: WHEN THIS OCCURS, ENGINE RUN-ON AND SUBSEQUENT LOSS OF OPERATOR CONTROL VIA THE NORMAL THROTTLE MECHANISM CAN OCCUR, WHICH COULD RESULT IN A VEHICLE ACCIDENT.

Remedy: REPLACE THE SUSPECT TURBO-CHARGER WITH A NEW TURBO-CHARGER.

THE BASE OF THE ELECTRONIC ACCELERATOR PEDAL IS MADE OF DIE CAST ALUMINUM. THE BASE MOUNTS DIRECTLY TO THE CAB FIREWALL. THE CAB FIREWALL IS NOT RIGID ENOUGH OR FLAT ENOUGH AT THE MOUNTING SURFACE, CAUSING STRESS ON THE ACCELERATOR BASE THAT WILL CAUSE THE MOUNTING PADS ON THE BASE OF THE PEDAL ASSEMBLY TO FAIL AND TOTALLY SEPARATE FROM THE FIREWALL.

Consequence: THIS CAN CAUSE LOSS OF SPEED CONTROL, DRIVER DISTRACTION, AND RESULT IN AN ACCIDENT.

Remedy: DEALERS WILL INSPECT THE ACCELERATOR PEDAL ASSEMBLY AND INSTALL A PLATE BETWEEN THE ACCELERATOR MOUNTING BASE AND THE FIREWALL ON THOSE UNITS WHERE THE BASE IS NOT BROKEN AND HAS NO VISIBLE SIGNS OF A CRACK. IF THE BASE IS BROKEN OR CRACKED, THE ACCELERATOR ASSEMBLY WILL BE REPLACED WITH A NEW REDESIGNED ACCELERATOR PEDAL ASSEMBLY.

THE DRIVE AXLE HOUSINGS CONSIST OF A PLATE STEEL CENTER SECTION AND TWO FORGED SPINDLES, ONE OF WHICH IS WELDED TO EACH END OF THE CENTER SECTION. EACH SPINDLE CONTAINS A KEYWAY SLOT IN WHICH THE LOCKING TAB FOR THE WHEEL BEARING NUT LOCKING MECHANISM IS INSERTED. THE LENGTH OF THE KEYWAY SLOT MAY NOT BE LONG ENOUGH TO ACCOMMODATE THE TAB CAUSING THE TAB TO BE DEFORMED OR DAMAGED DURING INSTALLATION.

ON CERTAIN MEDIUM AND HEAVY DUTY TRUCKS, A BRASS FITTING CONNECTS THE DOUBLE CHECK VALVE TO THE BRAKE RELAY VALVE. WITH CERTAIN INPUTS TO THE VEHICLE, THE WEIGHT OF THE CHECK VALVE ON THE FITTING CAN CAUSE THE ASSEMBLY TO RESONATE. THE SUBJECT VIBRATION CAN CAUSE EXCESSIVE STRAIN LEVELS IN THE FITTING, WHICH COULD EVENTUALLY FATIGUE AND FAIL.

Consequence: IF THE FITTING BREAKS, THE REAR SERVICE BRAKES WILL CEASE TO OPERATE WITHOUT WARNING, RESULTING IN AN EXTENDED STOPPING DISTANCE, INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL INSTALL A KIT TO REMOUNT THE DOUBLE CHECK VALVE WITH A FLEXIBLE HOSE ON THE MAJORITY OF VEHICLES. ON A SMALL NUMBER OF UNITS WITH CLEARANCE ISSUES OR TRACTION CONTROL, A KIT WITH A NEW RELAY VALVE THAT HAS A BUILT-IN DOUBLE CHECK VALVE WILL BE INSTALLED.
