Apr 01, 2015 – Oshkosh Corporation (Oshkosh) is recalling certain model year 2014-2015 S-Series Front Discharge Concrete Mixer vehicles manufactured September 24, 2013, to November 12, 2014. The affected vehicles have air tanks that hold less than the required 12 times the combined volume of the service brake chambers. As a result, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."

Apr 07, 2014 – Oshkosh Corporation (Oshkosh) is recalling certain model year 2012-2014 S-Series Ready Mixed Concrete trucks manufactured February 29, 2012, through January 27, 2014, and equipped with certain Cummins Westport Model ISL G engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.

Dec 30, 2013 – Oshkosh Corporation is recalling certain model year 2013 S-Series ready mixed concrete trucks manufactured May 1, 2013, through November 27, 2013. In the affected vehicles, the brake pedal bracket may loosen due to missing lock washers.

May 05, 2009 – OSHKOSH IS RECALLING 302 MY 2008 T-SERIES, TX, STA, H, P, S AND H-TRACTOR, AIRPORT RESCUE, FIREFIGHTING, COMMERCIAL, CONCRETE MIXER AND MILITARY TRUCKS AND HIGHWAY VEHICLES EQUIPPED WITH HALDEX AIR BRAKE SYSTEM CONTROL VALVE. THE RUBBER DIAPHRAGM USED INSIDE THE QUICK RELEASE VALVE (QRV) MAY DELAMINATE AND MAY CAUSE LEAKAGE LEVELS PAST AND/OR THROUGH THE DIAPHRAGM IN EXCESS OF PERMISSIBLE SPECIFICATIONS, OR COULD CAUSE A RESTRICTION IN THE AIR FLOW, THEREBY EFFECTING PRESSURE DELIVERY TO THE SERVICE BRAKES AND NOT ALLOW THE SERVICE BRAKES TO RELEASE.

Jul 02, 2007 – 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.

Oct 12, 2006 – 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.

Nov 06, 2001 – VEHICLE DESCRIPTION: FRONT DISCHARGE CONCRETE CARRIERS WITH 6- OR 8-WHEEL DRIVE DESIGNED TO OPERATE OFF-ROAD IN DIFFICULT SOILS AND TERRAIN THAT ARE BEYOND THE CAPABILITY OF CONVENTIONAL REAR DISCHARGE CONCRETE TRUCKS. THE FRAME RAIL FLANGE IMPINGED ON THE HEAD OF ONE OR MORE LOCKBOLTS WHICH ATTACH THE ANGLE IRON REAR PEDESTAL SUPPORT BRACKET TO THE FRAME.

Jul 11, 2001 – VEHICLE DESCRIPTION: AIRPORT SUPPORT, SNOW REMOVAL, CONCRETE CARRIER, AND MILITARY VEHICLES EQUIPPED WITH DRAG LINK ASSEMBLIES CONTAINING 24-DL MODEL BALL SOCKETS AND MANUFACTURED BY TRW. CERTAIN OF THE TIE ROD BALL-SOCKET BEARINGS HAVE A BELOW-SPECIFICATION CASE DEPTH AND/OR HARDNESS, WHICH CAN LEAD TO PREMATURE WEAR OF THE SOCKET.

Aug 01, 1995 – AIR SYSTEM BLOCKAGE IN THE AIR DRYER OCCURS DEGRADING THE MOISTURE REMOVING CAPABILITIES OF THE DRYER WHEN THE VEHICLE IS OPERATED IN A COLD ENVIRONMENT AND MOISTURE ACCUMULATES AND FREEZES IN THE AIR DRYER OR IN THE LINE BETWEEN THE DRYER AND THE AIR SYSTEM RESERVOIR. THE AIR DRYER CAN BECOME OVERPRESSURIZED CAUSING THE AIR DRYER CARTRIDGE TO SEPARATE FROM THE MOUNTING BASE.

Mar 11, 1994 – THE ELECTRICAL WIRING HARNESS DOES NOT ALWAYS INSURE A POSITIVE GROUND BETWEEN THE SELF-GROUNDING SEVEN WAY RECEPTACLE AND THE REAR LIGHT ASSEMBLIES THROUGH THE SLIDING RUNNING GEAR FRAME. VIBRATION FROM VEHICLE OPERATION CAUSES INTERMITTENT LOSS OF AN ELECTRICAL GROUND TO THE REAR FRAME.
