1975 INTERNATIONAL HARVESTER LOADSTAR SERIES Recalls (11)

Campaign:
76V103000 on 10/11/1979
Component:
Service brakes, air:antilock:wheel speed sensor
Affected:
5,509
Notes:
School bus chassis.possibility that false cycling of anti-lock systemsnormally occuring below 15 mph causes the brakes to release momentarily withoutwarning extending the stopping distance beyond the control of the driver.thiscondition can cause vehicle to crash without prior warning.(correctivemeasures to be submitted at a later date).bus-school.
Campaign:
78V145000 on 10/11/1979
Component:
Engine and engine cooling:exhaust system:emission control
Manufactured:
12/31/1972 - 09/30/1977
Affected:
2,500
Defect:
The vapor separator in the fuel tank evaporative omission system lacks the capacity to prohibit liquid gasoline from passing to the canister under certain fuel expansion conditions. gasoline would be discharged from the bottom of the canister onto the rear of engine, creating a fire hazard.
Correction:
Dealer will install an additional fuel separator to enlarge capacity, and add a discharge hose to the bottom of the fuel canister.
Notes:
Vehicle description: medium trucks.system: fuel; fuel tank.consequences of defect: in the event of a vehicle fire, serious personal injuryand property damage could result.note: the conditions which may promote the problem are: hot weather, use offuel with a high reid vapor pressure, and operating vehicle in frequentstop-start service.
Campaign:
77V020000 on 10/11/1979
Component:
Power train:axle assembly:axle shaft
Affected:
650
Defect:
The stub ends of the axle housing may not have been properly manufactured to specifications. these stubs would be of inadequate strength and could fracture. complete fracture would cause the front wheel, hub, and brake assembly to detach from the axle.
Correction:
The dealer will inspect and, if necessary, install the correct axle housing stubs.
Notes:
Vehicle description: heavy trucks.system: suspension; front axles.consequences of defect: this could result in loss of vehicle control and anaccident.
Campaign:
75V191000 on 10/11/1979
Component:
Service brakes, air:supply:hoses, lines/piping, and fittings
Affected:
8,500
Notes:
Ihc campaign no 75513.loadstar, cargostar trucks.possibility that duringextreme upward movement of the rear axle, a brake hose fitting connected to avalve mounted on a bracket located on the top front side of the rear axlehousing can come into contact with structure or components mounted on thevehicle frame.this contact could result in a fracture of the hose end fittingor valve body.fractures can result in a sudden loss of air pressure whichholds the spring brakes (parking) in release position and sudden application ofthe spring brakes will occur.(correct by inspecting and revising to hoserouting or valve mounting).
Campaign:
75V047000 on 10/11/1979
Component:
Service brakes, air:drum
Affected:
400
Notes:
International harvester campaign no 75503.transtar co,transtar conv.,paystar,loadstar,cargostar,fleetstar.possibility that the cam brake anchorpins were improperly processed (hardened).if cam brake are assembled usingimproperly processed anchor pins, a fracture of pin could occur during brakeapplication, causing loss of proper tension of the brake shoes and reduction inthe effectiveness of the brakes.(correct by inspecting and replacing anchorpins with properly hardened anchor pins).
Campaign:
76V039000 on 10/11/1979
Component:
Steering:linkages
Affected:
7,207
Notes:
Ihc campaign no 76502.medium duty trucks with rockwell international 16.000and 18.000 front axles.possibility that due to a forging flaw the right orleft steering arm could break.faliure of the steering arm could result indetachment of the steering arm from the wheel spindle and lead to loss ofinspecting and replacing steering arm where necessary).
Campaign:
77V180000 on 10/11/1979
Component:
Wheels:multi piece
Affected:
21,980
Defect:
The deficiency exists in the front axle forged aluminum hubs. the deficiency which is in the barrel section between the inner and outer bearing, may result in cracks which could lead to hub failure. when hub failure occurs, the separated hub is retained on the axle spindle by the wheel bearing and adjusting nut.
Correction:
The dealer will replace the forged aluminum hubs with steel hubs, at no charge.
Notes:
Vehicle description: medium and heavy trucks.system: suspension; wheels, front axle hubs.consequences of defect: continued vehicle operation could allow the separatedhub with the wheel and tire to become disengaged from the vehicle. thiscondition could result in loss of vehicle control and an accident.note: advance failure warning will occur in the form of wheel bearing lubeleaks on the wheel rim or tire. in the event hub failure occurs during vehicleoperation, warnings to the operator will occur in the form of an audible sound,wheel vibration and the steering feel of a severely underinflated tire.
Campaign:
75V089000 on 10/11/1979
Component:
Power train:automatic transmission
Affected:
3,000
Notes:
International harvester campaign no 75506.fleetstar,fleetstar,paystar,cargostar,f8500m equipped with detroit allisonmt-650 transmission.trucks.possibility that vehicles equipped with mt-650automatic transmission may contain nylon particle contaminant within thegovernor assembly.a nylon particle could block an orifice in the governorvalve and result in unintentional transmission down shift with the possibilityof transmission disintergration.(correct by inspecting and replacing governorassembly where necessary).
Campaign:
75V117000 on 10/11/1979
Component:
Service brakes, air:antilock:control unit/module
Affected:
8,500
Notes:
International campaign no 77509.trucks loadstar, fleetstar, cargostar,tramstar, paystar, conco, 1971 thru 1975 to date.possibility that variousmalfunctions of the anti-lock computers module system can range fromillumination of the anti-lock failure warning light with no apparent effect onthe vehicle braking system to a momentary loss of brake effectiveness on one ormore axles.(correct by inspecting and replacing computer module).
Campaign:
79V211000 on 12/11/1979
Component:
Service brakes, air:drum
Manufactured:
02/28/1975 - 03/31/1979
Affected:
25,000
Defect:
As a result of severe shock and vibrations, the brake spiders on the involved vehicles may develop cracks near the camshaft mounting boss. the crack propagates across the spider until the camshaft boss is completely severed from the remainder of the spider. when the camshaft boss has completely severed, the s-cam, s-cam bracket, air chamber and slack adjuster can fall away from the brake spider resulting in a "no brake" condition on the wheel.
Correction:
The dealer will replace the front brake spiders on all affected vehicles used in snow plow dump and refuse hauling applications. this will be done at no charge.
Notes:
Vehicle description: medium and heavy trucks equipped with eaton 16-1/2 by 5inch s-cam.system: service brakes: brake spiders.consequences of defect: partial loss of front braking capability and imbalancescan affect vehicle stability during sudden stops. this can contribute to avehicle accident.
Campaign:
79V212000 on 12/11/1979
Component:
Engine and engine cooling:exhaust system:emission control
Manufactured:
12/31/1972 - 08/31/1978
Affected:
2,950
Defect:
The fuel separators on the involved vehicles may have thin walls due to a material thickness problem. the separators in these walls may crack and may allow fuel vapors or liquid fuel to leak into the engine under high pressure conditions.
Correction:
The dealer will install improved separators and relocate both the separator and fuel canister without charge.
Notes:
Vehicle description: buses equipped with fuel tank evaporative emissionsystems.system: fuel; fuel tank.consequences of defect: leaking fuel in the presence of a source of ignitioncould lead to a vehicle fire and injury to vehicle passengers.
