Recall campaigns

VEHICLE SPEED CONTROL 94V032000 1994-02-15 39,777 affected

Defect

FUEL INJECTION SYSTEM RECONFIGURATION TO COMPLY WITH ENGINE EMISSION STANDARDS CAUSE HIGHER ENGINE VIBRATION LEVELS WHICH LEAD TO EARLY WEAR AND COMPLETE FAILURE OF THE SECONDARY THROTTLE RETURN MECHANISM.

Consequence

IN THE EVENT THE PRIMARY THROTTLE RETURN FAILS, FAILURE OF THE SECONDARY THROTTLE RETURN SYSTEM WOULD NOT PROVIDE PROTECTION AGAINST LOSS OF THROTTLE CONTROL.

Remedy

A NEW PRODUCTION SECONDARY THROTTLE RETURN SYSTEM CONFIGURATION WILL BE INSTALLED.

POWER TRAIN 93V176000 1993-11-01 130 affected

Defect

THE DRIVESHAFT TO THE FRONT DRIVING AXLE IS SECURED TO A BRACKET USING TWO PILLOW BLOCKS. THESE BLOCKS ARE OF INSUFFICIENT STRENGTH TO SUPPORT THE DRIVESHAFT AND COULD FAIL.

Consequence

PILLOW BLOCK FAILURE ALLOWS THE DRIVELINE (JACKSHAFT)TO DROP DOWN ONTO THE ROADWAY AND CREATE A SAFETY HAZARD TO OTHER VEHICLES.

Remedy

MACK WILL INSTALL THICKER PILLOW BLOCKS AND SUPPORT U-BOLTS.
