DEFECT #1 - EXTERIOR LIGHTING:TURN SIGNAL:SWITCH
Posted on: 1996-11-14
Description
These buses have a turn signal lever that will not operate consistently in the lane change mode if the lever is not moved to the position where resistance to movement is felt.
Consequence
Should the rear signal lamps not flash when a lane change was being made, it could result in a vehicle following the bus to collide with the bus increasing the risk of personal injury and/or property damage.
Corrective Action
Operators will be mailed information concerning the proper method of using turn signals. A decal will also be provided to be placed on the instrument panel of each bus.
Notes
Owner notification:information and decals will be mailed to owner beginning december 10, 1996.note:owners not receiving this information free of charge within a reasonable time should contact navistar at 1-800-448-7825.also contact the national highway traffic safety administration's auto safety hotline at 1-800-424-9393.
DEFECT #2 - SERVICE BRAKES, HYDRAULIC:ANTILOCK
Posted on: 1996-09-25
Description
The wiring from the electronic control unit was connected to the wrong wheel sensor or to the wrong brake modulator valve. It is possible that either or both wiring may have occurred at either the front or rear axle or both axles.
Consequence
Should the anti-lock braking system (abs) wiring be crossed, it would result in a significant degradation in vehicle stopping distance. A signal would be sent to the wrong brake chamber when a brake imbalance is detected. This condition increases the risk of a vehicle accident.
Corrective Action
Dealers will inspect the abs wiring and, if necessary, properly connect.
Notes
Owner notification:owner notification is expected to begin october 8, 1996.note: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 navistar at 1-800-448-7825.also contact the national highway traffic safety administration's auto safety hotline at 1-800-424-9393.
DEFECT #3 - FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS
Posted on: 1995-09-25
Description
The fuel hose to the fuel filter is routed too close to the alternator belt causing the alternator belt to rub the fuel hose. This can cause a fuel leak.
Consequence
Fuel leakage can result in a vehicle fire if an ignition source is present.
Corrective Action
Dealers will strap the fuel hose to the chassis frame to insure a minimum of 2 1/2 clearance between the fuel hose and the alternator belt.
Notes
System: fuel; fuel lines; hoses; non-metallic.vehicle description: school and transit buses equipped with a 7.3 liter international diesel engine (engine codes 12nab, 12nac, and 12nad).note: 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 navistar international at 1-800-448-7825. Also contact the national highway traffic safety administration's auto safety hotline at 1-800-424-9393.
DEFECT #4 - SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:HOSES, LINES/PIPING, AND FITTINGS
Posted on: 1993-11-29
Description
The hydraulic steel brake lines from the master cylinder to the frame fittings are experiencing vertical flexing which causes fatigue cracks at the frame end of the assembly, resulting in brake fluid leakage. This can occur in one or both of the steel brake lines. In either case, the brake warning light will come on and the low pressure buzzer will activate.
Consequence
Should a crack and leakage develop in one of the lines,half of the braking system capability could be lost, impairing the stoppingability of the vehicle. If both brake lines fail, the entire service brakingsystem will become inoperative. In either case, an accident could result,causing damage to the vehicle and personal injury.
Corrective Action
Navistar dealers will install a new, redesigned primary and secondary brake line from the master cylinder to the frame rail fittings.
Notes
System: brakes; hydraulic; lines; metallic.vehicle description: school buses equipped with hydraulic brakes.note: if your vehicle is presented to an authorized dealer on an agreed uponservice date and the remedy is not provided within a reasonable time and freeof charge or the remedy does not correct the defect or noncompliance, you canobtain assistance by following the procedure described in the owner assistanceguide of your owner's manual. Also, contact the national highway trafficsafety administration's auto safety hotline at 1-800-424-9393.
DEFECT #5 - SUSPENSION:REAR:SPRINGS:AIR SUSPENSION SYSTEM
Posted on: 1993-05-27
Description
The pressure relief valve was omitted in the air tank. The air tank is the reservoir for the air suspension and is not brake related. Without the pressure relief valve, there is no back-up system to limit air pressure in the air suspension system.
Consequence
Lack of a back-up system to limit air pressure build upcan cause excessive pressure in the air tank and can cause the tank to rupture.this can result in personal injury to anyone in the vicinity.
Corrective Action
Install a pressure relief valve in the air tank.
Notes
System: suspension.vehicle description: school buses: models 4700 and 4900; heavy trucks: models3600, 3700, 3800, and 3900fg; incomplete chassis: model 1652sc.
DEFECT #6 - FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY:MOUNTING
Posted on: 1993-07-12
Description
The fuel tank cage assembly bolts mounting the vertical straps to the horizontal angle were assembled with the threaded end of the bolts facing the fuel tank.
Consequence
If the fuel tank cage is struck with sufficient force itis possible for the bolts to pierce the fuel tank and cause fuel leakage.fuel leakage exposed to a source of ignition can result in a fire.
Corrective Action
The fuel tank cage mounting bolts will be removed and reinstalled with the bolt head toward the tank.
Notes
System: fuel system; fuel tank assembly; fmvss 301.vehicle description: school bus chassis.
DEFECT #7 - VEHICLE SPEED CONTROL:LINKAGES
Posted on: 1993-02-26
Description
The bracket that supports and positions the hand throttle cable at the accelerator rod can be bent or misaligned during body assembly to the chassis.
Consequence
Bent or misaligned throttle cables can cause theaccelerator to stick in partial to full throttle position, resulting a unwantedvehicle speed and a possible vehicle accident.
Corrective Action
Replace the current throttle cable bracket with a new bracket; install at a different location.
Notes
System: fuel system.vehicle description: buses equipped with hand throttles.
DEFECT #8 - FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY
Posted on: 1992-07-31
Description
The fuel system failed the crash barrier test.
Consequence
The fuel tank was punctured, resulting in fluid lossgreater than allowed by fmvss 301, fuel system integrity. Fuel spills ina collision could lead to a vehicle fire if exposed to a source of ignition.
Corrective Action
Modify the fuel tank cage to comply with fmvss 301.
Notes
System: fuel tank assembly; fmvss 301.vehicle description: school buses with 35 gallon or 65 gallon fuel tanks andfuel tank cage systems.note: it is important that all affected buses be remedied. However, the recallshould not cause parents or school officials to be unduly alarmed. Nhtsa isunaware of any actual crashes in which the fuel system of a navistar chassisruptured. Many of the school buses involved in the recall have been in servicefor more than 12 years, and there has not been a single recorded fatalitybecause of a fire.
