2005 Mack Chn Recalls

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.

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.

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.

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.

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…

ON CERTAIN TRUCKS, A LEAK IN THE ASET AC FUEL INJECTION LINE MAY SPRAY FUEL ON THE EXHAUST GAS RECIRCULATION PIPES THAT CARRY HOT EXHAUST GASES .

THIS COULD POTENTIALLY RESULT IN AN ENGINE FIRE.

(PLEASE SEE NHTSA NO. 07V159/MACK RECALL NO. SCO323 FOR VEHICLES THAT HAVE HAD THIS REPAIR ALREADY PERFORMED.) THIS…

ON CERTAIN TRUCKS, THE FUEL LINE CROSSOVER BRACKET MAY PREMATURELY FAIL AND UNEXPECTEDLY FALL TO THE ROAD. THE LOCATION AND SIZE OF THE BRACKET DRAWS A CONCERN TO THE BRACKET BEING PICKED UP AND THROWN BY THE DRIVE AXLE WHEELS.

ON CERTAIN HEAVY DUTY CLASS 8 TRUCKS EQUIPPED WITH FXL AXLES, THERE IS A POTENTIAL THAT THE DRAGLINK MAY CONTACT THE BRAKE SLACK ADJUSTER DURING FULL WHEEL CUT AND ARTICULATION OF THE CHASSIS.

IF THIS OCCURS, THE SLACK ADJUSTER MAY BE DAMAGED TO A POINT WHERE BRAKE PERFORMANCE IS COMPROMISED, WHICH MAY RESULT IN A VEHICLE CRASH.

ON CERTAIN TRUCKS EQUIPPED WITH THE FXL AXLE AND MERITOR 16.5 X 5 BRAKES WITH DUST SHIELDS, THERE MAY BE INTERFERENCE BETWEEN THE DUST SHIELD MOUNTING BOLT AND THE KNUCKLE ON THE FRONT AXLE. AS A RESULT OF THE INTERFERENCE, THE BOLT JOINT BETWEEN THE WHEEL END AND THE KNUCKLE MAY NOT MEET THE TORQUE REQUIREMENTS.
