Jun 06, 1988 – THE ENGINE OIL COOLER GASKET MAY FAIL AND ALLOW OIL TO LEAK INTO THE ENGINE COMPARTMENT.

Apr 13, 1988 – THE CLUTCH MOUNTING HOLES WERE NOT DRILLED DEEP ENOUGH TO SECURE THE CLUTCH TO THE FLYWHEEL.

Jan 04, 1988 – THE ELECTRONIC FUEL CONTROL BYPASS VALVE ON THE FUEL PUMP MAY MALFUNCTION WHEN IN THE BYPASS MODE.

Jan 22, 1986 – 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.

Jan 22, 1986 – 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.

Apr 12, 1985 – 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.

Sep 27, 1983 – 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.
