The issue
SUBJECT ENGINES MAY EXPERIENCE A LOSS OF THE GOVERNOR SERVO PIN. THIS WOULD RESULT IN THE ENGINE AND VEHICLE CONTINUING AT THEIR RESPECTIVE SPEEDS UNTIL A CHANGE IN LOAD OCCURS (I.E. TERRAIN, BRAKES OR CLUTCH) AND ENGINE BRAKING COULD BE REDUCED WITH A SUBSEQUENT INCREASE IN STOPPING DISTANCE AND THE RISK OF A CRASH. CORRECTION: THE GOVERNOR RACK SERVO CYLINDER ASSEMBLY WILL BE REPLACED ON AFFECTED ENGINES.
Description (français)
La goupille d'asservissement du régulateur des véhicules dotés des moteurs 3306B et 3406B peut tomber. Le véhicule conserve alors la même vitesse jusqu'à ce qu'il y ait changement de la charge (c.-à-d. dénivellation du terrain, freinage ou embrayage) et peut causer une diminution de la capacité de freinage, ce qui entraîne une augmentation de la distance de freinage et des risques de collision.
