1991 INTERNATIONAL HARVESTER 3800 Recalls (5)
- Campaign:
- 92V102000 on 07/30/1992
- Component:
- Fuel system, gasoline:storage:tank assembly
- Manufactured:
- 08/31/1978 - 06/30/1992
- Affected:
- 185,000
- Defect:
- 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.
- Correction:
- 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.
- Campaign:
- 93V092000 on 05/26/1993
- Component:
- Suspension:rear:springs:air suspension system
- Manufactured:
- 12/31/1989 - 02/28/1993
- Affected:
- 193
- Defect:
- 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.
- Correction:
- 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.
- Campaign:
- 93V112000 on 07/11/1993
- Component:
- Fuel system, gasoline:storage:tank assembly:mounting
- Manufactured:
- 02/28/1991 - 09/30/1991
- Affected:
- 10,629
- Defect:
- 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.
- Correction:
- 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.
- Campaign:
- 95V127000 on 06/27/1995
- Component:
- Vehicle speed control:cables
- Manufactured:
- 05/31/1988 - 02/28/1991
- Affected:
- 21,742
- Defect:
- The wire end of the hand throttle cable passes through a split plastic grommet in the accelerator rod. this wire can work through the slot in the grommet and become lodged between the grommet and the edge of the hole in the accelerator rod.
- Consequence:
- If the throttle wire becomes lodged, the accelerator can stick and not return to idle position potentially affecting the operator's ability to control the vehicle and increasing the potential for an accident.
- Correction:
- Dealers will repair buses by installing a new cable grommet without a slot; install a new cable stop; and readjust the throttle cable.
- Notes:
- System: fuel; throttle linkages; accelerator; flexible.vehicle description: school buses.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.
- Campaign:
- 96V192000 on 11/13/1996
- Component:
- Exterior lighting:turn signal:switch
- Manufactured:
- 12/31/1980 - 07/31/1994
- Affected:
- 171,638
- Defect:
- 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.
- Correction:
- 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.
