NHTSA Campaign 15V330000

ENGINE AND ENGINE COOLING:ENGINE

Issued by Oshkosh Corporation · Reported Jun 1, 2015 · 44 vehicles affected

What's wrong

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

If engine oil comes into contact with a hot surface, there is an increased risk of a fire.

Remedy

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.
