Affected:
531
Notes:
Kt450 and kta600 engines.engine gear driven fan.possibility that the geardriven fan hub assembly which incorporates a rubber isolater between twomembers.this rubber material may be of insufficient quality.under normalengine operation, the isolator may deteriotate resulting in separation of theinner and outer fan hub members.if this occurs while engine is running, fanwill come loose and be driven into the radiator, metal fragments could beejected and possibly cause serious injury to vehicle occupants or persons inthe vicinity.(correct by inspecting and improved designed materials).materials)%ct b
Campaign:
82E002000 on 01/31/1982
Component:
Engine and engine cooling:engine
Manufactured:
10/31/1981 - 10/31/1981
Affected:
936
Defect:
It is possible that the flywheels in some of the involved engines have cracks located within the pilot bore area. these cracks may progress under operational stresses and lead to fragmentation of the flywheel.
Correction:
The manufacturer will inspect and, if necessary, replace the engine flywheel without charge to owner.
Notes:
Vehicle category: trucks.system: engine; flywheel.consequences of defect: a broken flywheel would cause the engine to stopfunctioning. a disabled vehicle could cause an accident on the road.
Campaign:
82E007000 on 04/04/1982
Component:
Engine and engine cooling:engine
Manufactured:
12/31/1977 - 04/30/1981
Affected:
69
Defect:
It is possible that the wall thickness of the engine mounting pad is outside of design specifications. if this condition exists, failure of the mounting pad in a bus application could cause the engine to fall to the roadway.
Correction:
All suspect cylinder blocks found to contain the defect will be modified as good engineering dictates, until new cylinder blocks can be installed.
Notes:
Vehicle category: buses equipped with cummins engines.system: engine; cylinder block mounts, part no. 188980.consequences of defect: if the engine falls, the fuel, lube oil, coolant andpower steering lines will be severed. this could cause loss of vehicle controland an accident. the engine, lying in the roadway, could also cause an accidentinvolving other vehicles.
Campaign:
83E014000 on 11/07/1983
Component:
Vehicle speed control
Manufactured:
06/30/1983 - 07/31/1983
Affected:
2,250
Defect:
The throttle may have a protrusion which can be impeded by the fuel pump cover and cause loss of accelerator control. the interference occurs between the throttle lever stop pin and a rivet securing a side plate on the fuel pump housing.
Correction:
The throttle lever stop pin will be ground flush to the throttle lever on the fuel pump side.
Notes:
Vehicle category: trucks equipped with cummins engines, models nh and k.system: fuel; throttle levers.consequences of defect: a jammed throttle can result in loss of vehicle controlpossibly leading to an accident. serious engine damage or personal injury canalso occur.note: units containing the suspect engines should not be driven until inspectedand corrected.
Campaign:
85E016000 on 04/16/1985
Component:
Vehicle speed control
Manufactured:
12/31/1983 - 03/31/1985
Affected:
219,000
Defect:
The stop pin which is swaged into the throttle lever, so as to allow the throttle lever to absorb excessive throttle linkage travel and maintaining the ability to control the engines speed. this stop pin could be a mismatch and could loosen causing the lever stop pin assembly to fall apart. consequence of defect: this condition, causes the tensioning spring attached to the throttle lever assembly to separate from the lever causing the throttle lever to either move to full throttle position, to the idle position, or remain in the position the lever was in at the moment of failure. this could cause the vehicle to be uncontrolable and result in an accident and personal injury.
Correction:
All throttle lever assemblies will be replaced with new modified type to eliminate the potential defect.
Notes:
Vehicle description: trucks equipped with cummins engines.system: throttle linkage.
Campaign:
86E002000 on 01/27/1986
Component:
Vehicle speed control:cables
Affected:
406
Defect:
Accelerator control system failed to meet requirements of fmvss 124, which requires that when the throttle linkage fails, the engine speed returns to idle. the secondary throttle lever return spring and mounting bracket were omitted during engine to chassis assembly. consequence of defect: should the main throttle spring break during operation the throttle could remain open resulting in a runaway engine with possible crash.
Correction:
Install secondary spring and bracket on all suspected engines.
Notes:
System: accelerator.vehicle category: trucks equipped with b series, 4bt 3.9 liter engines.
Campaign:
86E003000 on 01/27/1986
Component:
Engine and engine cooling:engine
Manufactured:
12/31/1984 - 12/31/1985
Affected:
15
Defect:
Due to inadequate bonding, the crankshaft vibration damper assembly could separate. consequence of defect: the crankshaft vibration damper assembly could separate upon failure of the bonding agent and become a projectile. the engine compartment may contain the projectile. however, if the hood is open, the projectile may seriously injury anyone near the truck.
Correction:
Replace with new crankshaft vibration damper.
Notes:
System: engine/crankshaft.vehicle category: trucks equipped with this 8.3 liter, c series engine.
Campaign:
87E007000 on 03/12/1987
Component:
Vehicle speed control:linkages
Affected:
850
Consequence:
If the throttle sticks in an open position the vehiclecould become uncontrolable and result in vehicle crash.
Correction:
Install a throttle linkage kit to meet the requirements of fmvss 124.
Notes:
System: accelerator control fmvss 124.vehicle category: trucks.descript ion of defect: during truck body assembly the throttle linkage wasinstalled in such a way it could cause it to hang up on the dog house.failsto meet requirement of fmvss 124.
Campaign:
88E006000 on 02/15/1988
Component:
Fuel system, gasoline:storage
Affected:
43
Defect:
The electronic fuel control bypass valve on the fuel pump may malfunction when in the bypass mode.
Consequence:
If the above condition exists, the engine couldaccelerate to full throttle unexpectedly if cruise control or power take offfunction is activated.
Correction:
The electronic fuel control bypass valve has been redesigned to prevent loss of throttle control with the pace sysems when operating in cruise control.
Notes:
System: electronic fuel control system.(pace)vehicle category: heavy duty trucks.
Campaign:
88E010000 on 04/21/1988
Component:
Power train:clutch assembly:pedal/linkage
Manufactured:
12/31/1976 - 12/31/1987
Affected:
260
Defect:
The clutch mounting holes were not drilled deep enough to secure the clutch to the flywheel.
Consequence:
This inadequate depth of mounting holes allows theattaching capscrews to bottom out and not compress the lockwasher or secure theclutch to the flywheel. this could result in the clutch separating from theflywheel while the engine is operating.
Correction:
Retap attaching holes to proper depth to adequately secure the clutch to the flywheel.
Notes:
Vehicle category: heavy duty trucks and buses.
Campaign:
88E015000 on 06/08/1988
Component:
Engine and engine cooling:engine
Manufactured:
11/30/1987 - 02/29/1988
Affected:
16,500
Defect:
The engine oil cooler gasket may fail and allow oil to leak into the engine compartment.
Consequence:
During high temperature engine operation, loss oflubricant may occur rapidly and lead to engine damage or fire resulting from thelubricating oil sprayed from the gasket rupture onto the hot exhaust system.
Correction:
Installation of a new type gasket with a steel core.
Notes:
System: lubrication/engine.vehicle category: heavy trucks.
