Defect
Dual-Tech, Inc. (Dual-Tech) is recalling certain model year 2009-2014 Ford F-550 Super Duty trucks modified by Dual-Tech, 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 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.
Remedy
Dual-Tech will notify owners, and dealers will install a new pressure switch kit that moves the switch away from the exhaust system, free of charge. The recall began June 20, 2014. Owners may contact Dual-Tech customer service at 1-800-852-0345.
