    Engine and Engine Cooling / Engine

    Defect, in the NHTSA record
    Oshkosh Corporation (Oshkosh) is recalling certain model year 2012-2014 S-Series Front Discharge Concrete Mixer vehicles manufactured February 29, 2012, to November 13, 2013, and equipped with certain Cummins Westport ISL G engines. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.
    Consequence, in the NHTSA record
    If engine oil comes into contact with a hot surface, there is an increased risk of a fire.
    Remedy, in the NHTSA record
    Cummins will notify owners on behalf of Oshkosh, and dealers will secure the ends of the 90-degree elbow. In addition, the electronic control module (ECM) will be reprogrammed with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact Oshkosh customer service at 1-888-686-7278 or Cummins customer service at 1-800-343-7357.

    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.
    Consequence, in the NHTSA record
    The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.
    Remedy, in the NHTSA record
    Cummins Inc. and Cummins Wesport Inc. will notify owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge.
