Peterbilt Truck: Engine
Affects Peterbilt Truck · 1987–1988 — about 57 vehicles.
The hazard
VEHICLES EQUIPPED WITH CATERPILLAR 3306B OR 3406B ENGINES MAY EXPERIENCE A LOSS OF THE GOVERNOR SERVO PIN. THIS WOULD RESULT IN THE ENGINE AND VEHICLE CONTINUING AT THEIR SAME RESPECTIVE SPEEDS UNTIL A CHANGE IN LOAD OCCURS (I.E. TERRAIN, BRAKES OR CLUTCH) AND COULD REDUCE ENGINE BRAKING WITH A SUBSEQUENT INCREASE IN STOPPING DISTANCES AND THE RISK OF A CRASH. CORRECTION: THE RACK SERVO CYLINDER ASSEMBLY WILL BE REPLACED ON AFFECTED ENGINES.
