07V320000BrakesJuly 2, 2007 · 1,755 units

Defect

ON CERTAIN TRUCKS EQUIPPED WITH BENDIX SR-7 SPRING BRAKE MODULATING VALVES, THE INTERNAL RUBBER CHECK VALVE MAY LEAK CAUSING A DELAY IN THE APPLICATION OF THE SPRING BRAKES TO PARK THE VEHICLE AFTER THE OPERATOR PULLS THE DASH VALVE BUTTON.

Consequence

THIS COULD DELAY OR FAILURE IN APPLYING THE PARKING BRAKES WHICH COULD RESULT IN A VEHICLE ROLL AWAY, INCREASING THE RISK OF A CRASH.

Remedy

OSHKOSH IS WORKING WITH BENDIX TO REPAIR THESE VEHICLES (PLEASE SEE 07E-037). BENDIX WILL INSTALL A CHECK VALVE REPAIR KIT FOR THE AFFECTED SR-7 SPRING BRAKE MODULATING VALVE FREE OF CHARGE. THE RECALL BEGAN ON OCTOBER 19, 2007. OWNERS MAY CONTACT BENDIX AT 440-329-9000 AND OSHKOSH AT 1-920-235-9151.

06V390000TransmissionOctober 12, 2006 · 380 units

Defect

ON CERTAIN TRUCKS EQUIPPED WITH ARVINMERITOR AXLE ASSEMBLIES, THE TORQUE ROD TOWER HAS A NONCONFORMING LOCATION AND WELD. THE WELD CAN CRACK, LEADING TO THE TANDEM AXLE LOSING ITS ANCHOR POINT, CAUSING THE DRIVELINE TO BEND TO AN ANGLE OUTSIDE ITS OPERATING PERIMETERS.

Consequence

IN TURN, THIS CAN RESULT IN THE DRIVELINE BREAKING OR FORCING THE ENGINE TO STOP. IT IS ALSO POSSIBLE FOR THE TANDEM AXLE TO DROP TO THE GROUND AND TURN UNDER THE VEHICLE CREATING A CONDITION THAT MIGHT INCLUDE LOSS OF VEHICLE CONTROL, WHICH COULD RESULT IN A CRASH.

Remedy

DEALERS WILL INSPECT THE TORQUE TOWERS ON THE REAR TANDEM AND, IF CRACKS ARE FOUND, THE TORQUE TOWER WILL BE REWELDED ACCORDING TO INSTRUCTIONS. OSHKOSH HAS TELEPHONED ALL OWNERS IN SEPTEMBER 2006, ADVISING THEM THAT UNTIL THE TORQUE TOWER IS REWELDED, OWNERS SHOULD INSPECT FOR CRACKS AT THE BASE OF THE TORQUE TOWERS ON THE REAR TANDEM ON A WEEKLY BASIS. THE RECALL BEGAN ON JANUARY 15, 2007. OWNERS MAY CONTACT OSHKOSH AT 1-920-233-9427.
