THE AIR LINE PLUMBING OF THE AIR BRAKE FOOT VALVE WAS CONNECTED TO THE SUPPLY RESERVOIR INSTEAD OF THE PRIMARY RESERVOIR. THIS REMOVES THE PRIMARY BRAKE SYSTEM AS A BACK-UP IN THE EVENT OF A SECONDARY BRAKE SYSTEM FAILURE.

Consequence: IN THE EVENT OF A SECONDARY SYSTEM FAILURE, THERE WOULDBE NO AIR TO THE FOOT VALVE AND THE VEHICLE WOULD BE WITHOUT SERVICE BRAKESCAUSING LOSS OF BRAKING CONTROL WHICH COULD RESULT IN AN ACCIDENT.

Remedy: REROUTE THE FOOT VALVE AIRLINES TO THE PRIMARY AIR TANK.

Reported: 1994-08-02 (August 2, 1994) · Model years: 1994, 1995

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.

Reported: 1994-10-07 (October 7, 1994) · Model years: 1994, 1995

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.

Reported: 1995-08-02 (August 2, 1995) · Model years: 1995, 1996

THESE VEHICLES WERE BUILT WITH AN IMPROPERLY PLUMBED BRAKE SYSTEM WHICH AFFECTS THE BRAKING ON THE REAR AXLE WHEN RUNNING EITHER BOBTAIL OR PULLING A TRAILER.

Consequence: THIS CONDITION CAN AFFECT THE STOPPING ABILITY OF THE VEHICLE BECAUSE THE FRONT STEER AXLE BRAKES AND TRAILER'S BRAKES WOULD BE DOING MOST OF THE BRAKING. INCREASED STOPPING DISTANCES WOULD BE REQUIRED CAUSING ACCELERATED WEAR ON THE STEER AXLE AND THE TRAILER BRAKES.

Remedy: NAVISTAR DEALERS WILL INSPECT VEHICLES AND REPAIR BY INSTALLING BRAKE LINES AND FITTINGS AS REQUIRED.

Reported: 2001-02-01 (February 1, 2001) · Model years: 1996, 1997, 1998, 1999, 2000, 2001

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH AIR BRAKE HALDEX AUTOMATIC SLACK ADJUSTERS, LONG STROKE BRAKE CHAMBERS, AND DANA BRAKES. THE AUTOMATIC SLACK ADJUSTER ANCHOR BRACKETS CAN FAIL DUE TO FATIGUE FRACTURE AND COMPLETELY SEPARATE, CAUSING THE SLACK ADJUSTERS TO FUNCTION AS MANUAL SLACK ADJUSTERS.

Consequence: IF THE SUPPORT BRACKET FOR AN AUTOMATIC SLACK ADJUSTER FAILS, THE BRAKES AT THAT WHEEL END WILL NOT AUTOMATICALLY ADJUST. AS THE BRAKE LININGS WEAR, THE VEHICLE WILL HAVE REDUCED BRAKING CAPACITY, INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL INSTALL A NEW BRACKET ON EACH SUSPECT SLACK ADJUSTER. OWNER NOTIFICATION BEGAN FEBRUARY 22, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT INTERNATIONAL AT 1-800-448-7825.

Reported: 1996-11-22 (November 22, 1996) · Model years: 1997

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.

Consequence: THIS LOCKING TAB PREVENTS THE WHEEL BEARING NUT FROM LOOSENING DURING VEHICLE OPERATION. IF THIS TAB IS DEFORMED, THE NUT CAN LOOSEN ALLOWING THE WHEEL TO SEPARATE FROM THE AXLE INCREASING THE RISK OF A VEHICLE ACCIDENT.

Remedy: DEALERS WILL REPLACE THE DRIVE AXLE HOUSING NUTS WITH A CONVENTIONAL WHEEL NUT HARDWARE SYSTEM.

Reported: 1996-11-27 (November 27, 1996) · Model years: 1997

VEHICLE DESCRIPTION: SCHOOL BUSES AND HEAVY DUTY TRUCKS EQUIPPED WITH REAR AXLE ASSEMBLIES PRODUCED BY DANA SPICER. CERTAIN REAR AXLE ASSEMBLIES WERE IMPROPERLY HEAT TREATED WHICH COULD ALLOW PINION BREAKAGE AT THE PINION THREADS.

Consequence: CRACKS CAN INITIATE AND RESULT IN SEPARATION OF THE THREADED END OF THE PINION RESULTING IN SEPARATION OF THE YOKE AND DRIVE LINE FROM THE REAR AXLE INCREASING THE RISK OF A VEHICLE ACCIDENT.

Remedy: DEALERS WILL REPLACE THE REAR AXLE CARRIER/PINION ASSEMBLY.
