SERVICE BRAKES, AIR:SUPPLY:HOSES, LINES/PIPING, AND FITTINGS

Issued by DAIMLER TRUCKS NORTH AMERICA · Reported May 16, 2011 · 94 vehicles affected

What's wrong

DTNA IS RECALLING CERTAIN MODEL YEAR 2011-2012 WESTERN STAR 4900 VEHICLES MANUFACTURED FROM APRIL 1, 2010, THROUGH MAY 13, 2011, WITH STANDARD CAB HEIGHT AND A DD13 ENGINE. THE SUPPLY AND DELIVERY AIRLINES FOR THE FOOT VALVE MAY CONTACT THE AIR INTAKE ON THE ENGINE. RELATIVE MOTION BETWEEN THE CAB AND THE ENGINE MAY ALLOW THE DELIVERY AIRLINES TO CHAFE ON THE AIR INTAKE.

Consequence

A HOLE IN THE DELIVERY AIR LINE MAY DEVELOP, EVENTUALLY LEADING TO REDUCED BRAKING CAPACITY TO THE FRONT OR REAR BRAKES, INCREASING THE RISK OF A CRASH.

Remedy

DEALERS WILL INSPECT THE AIR LINES AND REROUTE IF NECESSARY TO PROVIDE ADDITIONAL CLEARANCE TO THE ENGINE AIR INTAKE. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON DECEMBER 21, 2011. OWNERS MAY CONTACT DTNA AT 1-800-547-0712.
