Navistar 9100 recalls by model year

Reported: 1998-03-25 (March 25, 1998) · Model years: 1997, 1998

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH CATERPILLAR C-10 OR C-12 ENGINES. A BRACKET OR P-CLAMP AT THE REAR OF THE ENGINE THAT SUPPORTS THE COMPRESSOR DISCHARGE LINE WAS OMITTED.

Consequence: IF THE COMPRESSOR DISCHARGE LINE FAILS, THE AIR SYSTEM COULD BE DEPLETED AND CAUSE THE PARKING BRAKES TO APPLY. THIS CONDITION CAN CAUSE THE VEHICLE TO SLOW DOWN OR STOP UNEXPECTEDLY, CAUSING A VEHICLE CRASH WHICH COULD RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.

Remedy: DEALERS WILL INSTALL P-CLAMPS AND A BRACKET AT THE REAR OF THE ENGINE.

Reported: 1998-11-09 (November 9, 1998) · Model years: 1997, 1998, 1999

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH SPICER SPL170 55MM CENTER BERING PACKAGE. THE END YOKE RETAINING NUT CAN LOOSEN.

Consequence: IF THIS CONDITION OCCURS, THE DRIVE LINE CAN VIBRATE AND SEPARATE FROM THE VEHICLE, CAUSING VEHICULAR DAMAGE, OR PERSONAL INJURY, OR BOTH.

Remedy: DEALERS WILL REMOVE THE 55MM CENTER BEARING PACKAGE AND COUPLER SHAFT, AND REPLACE IT WITH A NEW COUPLER SHAFT AND A 60MM CENTER BEARING PACKAGE. AN INTERIM REMEDY CAN BE IMPLEMENTED BY PLACING A SPOT WELD ON THE COUPLING SHAFT THREADS UNTIL PARTS ARE AVAILABLE.

Reported: 2000-01-24 (January 24, 2000) · Model years: 1999

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS. THE ANTILOCK TRACTION RELAY VALVES WERE INCORRECTLY ASSEMBLED BY THE SUPPLIER. AN EXTRA CHECK VALVE WAS INSTALLED WHICH WILL NOT ALLOW THE TRACTION CONTROL SYSTEM TO FUNCTION PROPERLY.

Consequence: THE REAR BRAKES CAN BE APPLIED AUTOMATICALLY DURING A TRACTION EVENT AND NOT RELEASE UNTIL THE AIR SYSTEM PRESSURE IS DEPLETED.

Remedy: DEALERS WILL INSPECT THESE VEHICLES AND ALL ANTILOCK TRACTION RELAY VALVES FOUND DEFECTIVE WILL BE REPLACED.

Reported: 1999-03-16 (March 16, 1999) · Model years: 1999

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS, TRANSIT AND SCHOOL BUSES, EQUIPPED WITH MERITOR AIR BRAKE AUTOMATIC SLACK ADJUSTERS. SOME OF THE AUTOMATIC SLACK ADJUSTERS HAD INSUFFICIENT TORQUE APPLIED TO THE GUIDE PAWL CAP SCREW.

Consequence: WITHOUT SUFFICIENT TORQUE ON THE GUIDE PAWL CAP SCREW, THE BRAKES COULD GRADUALLY LOSE ADJUSTMENT, INCREASING THE VEHICLE STOPPING DISTANCE.

Remedy: DEALERS WILL CHECK THE TORQUE ON THE AUTOMATIC SLACK ADJUSTER GUIDE PAWL. IF THERE IS NO TORQUE, THE BRAKES WILL BE ADJUSTED AND THE GUIDE PAWL WILL BE TIGHTENED TO 15-20 FT. LBS.

Reported: 1999-05-04 (May 4, 1999) · Model years: 1999

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH DANA/SPRAGUE WINDSHIELD WIPER ASSEMBLIES. THE KNURLED PIVOT SHAFT (WHICH OPERATES THE WINDSHIELD WIPER ARM) IS WELDED TO A LEVER, WHICH CONNECTS TO LINKAGE FROM THE WIPER MOTOR. THE WELD AT THE PIVOT SHAFT TO LEVER CAN FAIL.

Consequence: SHOULD A FAILURE OCCUR DURING INCLEMENT WEATHER ON THE DRIVER'S SIDE WHILE THE VEHICLE IS IN MOTION, THE OPERATOR'S VISION WOULD BE PARTIALLY OBSCURED.

Remedy: DEALERS WILL INSPECT THE WIPER SYSTEM, CONDUCTING A "STALL" TEST TO VALIDATE THE INTEGRITY OF THE WELD. ALL WIPER ASSEMBLIES FAILING THIS TEST WILL BE REPLACED.
