As NHTSA's recall record states it for campaign 14V491000.
Defect description
All Wheel Drive Equipment Mfg., Inc. (All Wheel) is recalling certain 2011-2012 Ford F-550 Super Duty chassis with a 6.8L gasoline engine, modified by All Wheel and equipped with certain Muncie Power Products PTO Assemblies. In the affected vehicles, oil may leak from the PTO pressure switch onto a thermal blanket covering the exhaust.
Safety consequence
The leaking oil may soak into the thermal blanket covering the exhaust, which when combined with heat from exhaust, may result in an increased risk of fire.
Manufacturer remedy
All Wheel has notified the affected owners, and dealers will install a new pressure switch kit that moves the switch away from the exhaust system, free of charge. Owners were notified on June 10, 2014 by certified mail. Owners may contact All Wheel customer service at 1-800-311-4778.
