International Harvester 3600 recalls

What is wrong

On certain school and transit buses built with bosch zero offset pin slide (zops) hydraulic disc brakes, the zops hydraulic disc brakes may experience calipers sticking in the applied position, which can result in excessive or abnormal heat generation at one or more of the brakes.

Risk

The combination of the following factors may collectively result in an unreasonable risk to motor vehicle safety: potential fire at a wheel end, high incident rates of stuck calipers, and evacuation and containment concerns relating to multiple passengers.

Remedy

International will notify its customers and repair the buses free of charge. The recall began october 29, 2004.

Recall number 03V062000 · Recall details

What is wrong

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.

Risk

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.

Remedy

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.

Recall number 96V192000 · Recall details

What is wrong

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.

Risk

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.

Remedy

Dealers will inspect the ABS wiring and, if necessary, properly connect.

Recall number 96V174000 · Recall details

What is wrong

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.

Risk

Fuel leakage can result in a vehicle fire if an ignition source is present.

Remedy

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.

Recall number 95V179000 · Recall details

What is wrong

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.

Risk

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.

Recall number 94V196000 · Recall details

What is wrong

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.

Risk

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.

Recall number 94V144000 · Recall details

What is wrong

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.

Risk

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.

Remedy

Navistar dealers will install a new, redesigned primary and secondary brake line from the master cylinder to the frame rail fittings.

Recall number 93V188000 · Recall details

What is wrong

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.

Risk

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.

Remedy

The fuel tank cage mounting bolts will be removed and reinstalled with the bolt head toward the tank.

Recall number 93V112000 · Recall details

What is wrong

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.

Risk

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.

Remedy

Install a pressure relief valve in the air tank.

Recall number 93V092000 · Recall details

What is wrong

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.

Risk

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.

Remedy

Replace the current throttle cable bracket with a new bracket; install at a different location.

Recall number 93V025000 · Recall details

What is wrong

The fuel system failed the crash barrier test.

Risk

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.

Remedy

Modify the fuel tank cage to comply with fmvss 301.
