Summary derived from NHTSA notice
Reason for Recall
As stated by NHTSA
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.
Reported concern (NHTSA)
If engine oil comes into contact with a hot surface, there is an increased risk of a fire.
Recommended Action
Per NHTSA guidance
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.
