Date: 2007-10-23. Systems: TRAILER HITCHES.
Defect: ON CERTAIN TRUCKS EQUIPPED WITH A SAF HOLLAND SIMPLEX FIFTH WHEEL, THE LEVER ARM PIVOT BOLT MAY HAVE BEEN OVER TIGHTENED. AN OVER TIGHTENED PIVOT BOLT CAN DISTORT THE PIVOT BOLT SPACER SLEEVE, WHICH MAY PREVENT THE FIFTH WHEEL LATCH JAW FROM CLOSING AND LATCHING SECURELY AROUND THE TRAILER KING PIN.
Consequence: THERE IS A POSSIBILITY THAT THE PIVOT BOLT CAN BECOME LOOSE WITHOUT THE DRIVER'S KNOWLEDGE. WHEN THIS OCCURS, THE DRIVER COULD DRIVE AWAY AND THE TRAILER COULD BECOME DISENGAGED, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE PIVOT BOLT AND SLEEVE WITH A HEX HEAD SHOULDER BOLT AND WASHER FREE OF CHARGE. THE RECALL BEGAN ON JANUARY 28, 2008. OWNERS MAY CONTACT MACK TRUCKS AT 1-800-528-6586.

Date: 2007-09-05. Systems: FUEL SYSTEM, DIESEL.
Defect: ON CERTAIN TRUCKS EQUIPPED WITH ASET AC MODEL ENGINES, THE ENGINE AS CONFIGURED WITH AN EXTERNAL EXHAUST GAS RECIRCULATION SYSTEM MAKES SERVICING THE FUEL INJECTION LINES DIFFICULT WHEN USING TRADITIONAL TOOLS. THEREFORE, IT IS POSSIBLE FOR FUEL LEAKS TO DEVELOP WHEN REMOVING AND INSTALLING THE FUEL INJECTION LINES.
Consequence: A LEAK IN THE FUEL INJECTION LINE MAY SPRAY FUEL ON THE HOT SURFACES OF THE EXHAUST GAS RECIRCULATION SYSTEM, WHICH COULD RESULT IN AN ENGINE FIRE.
Remedy: DEALERS WILL REPLACE THE FUEL INJECTION LINES FREE OF CHARGE. NOTE: THIS RECALL SUPERSEDES A PREVIOUS CAMPAIGN CONDUCTED IN 2006 (PLEASE SEE 06V392). THE RECALL BEGAN ON SEPTEMBER 11, 2007, WITH SUBSEQUENT MAILINGS EVERY SIX WEEKS UNTIL APRIL 2008. OWNERS MAY CONTACT MACK AT 800-528-6586.

Defect: ON CERTAIN TRUCKS EQUIPPED WITH PARKER SINGLE CHECK VALVES (SCV) PROVIDED BY BENDIX. THE DEFECT EXISTS IN THE PARKER SCV THAT CONNECTS WITH THE SUPPLY PORT OF THE SR-7 SPRING BRAKE MODULATING VALVE. AFTER PROLONGED USE OF THE PARKER SCV, THE VALVE BODY RETAINER MAY BECOME EXCESSIVELY WORN AND EVENTUALLY BREAK APART. PIECES OF THE PARKER SCV CAN BECOME LODGED INSIDE THE SR-7 SPRING BRAKE MODULA (excerpt)
Consequence: THIS CONDITION CAN CAUSE A DELAY IN THE APPLICATION OF THE SPRING BRAKES TO PARK THE VEHICLE AFTER THE OPERATOR PULLS THE DASH VALVE BUTTON. THESE CONDITIONS CAN OCCUR WITHOUT WARNING, LEADING TO UNINTENDED VEHICLE ROLLAWAY, BRAKE DRAG, OR IN THE CASE OF LOSS OF PRIMARY CIRCUIT, INABILITY TO MODULATE THE SPRING BRAKES. (excerpt)
Remedy: MACK IS WORKING WITH BENDIX TO REPLACE THE PARKER SINGLE CHECK VALVE. THE RECALL BEGAN ON JANUARY 9, 2008. OWNERS MAY CONTACT BENDIX AT 1-440-329-9000 OR MACK AT 1-800-528-6586. (excerpt)
