The defect
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.
The risk
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.
