What's wrong?
The PTO assembly on the 2012-2013 Super Duty F-550 is equipment that lets the truck use engine power to run an added work function, such as a body or accessory installed after the base truck was built. The pressure switch is part of that equipment, and it monitors pressure inside the power takeoff system while oil circulates through it.
On affected trucks equipped with certain Muncie Power Products PTO assemblies, the pressure switch is the leak point. Oil from that switch can drip onto a thermal blanket that covers the exhaust. That blanket is meant to manage exhaust heat, not absorb oil, so contamination puts oil directly on material wrapped around hot exhaust parts.
There is no warning sign before failure. Owners should not count on a dashboard light, noise, or visible leak before the oil reaches the exhaust blanket.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Leaking oil can soak into the thermal blanket over the exhaust. With exhaust heat, that oil raises the risk of fire. Schedule the recall repair soon, and call the dealer before another trip if you suspect an oil leak. Repair will be free at any franchised Super Duty dealer once available.
What should I do?
- Check your VIN to confirm your 2012-2013 Super Duty F-550 is included in this recall.
- Contact Super Duty customer service at 1-877-465-5832 to confirm current repair timing before scheduling service.
- Ask a franchised Super Duty dealer about the free PTO pressure-switch-kit repair that stops oil from leaking onto the exhaust thermal blanket.
- Bring the recall notice if you have it. If not, reference recall number 14V479 when you call.
- Park away from structures if you see oil leaking near the PTO pressure switch or smell burning oil, then ask the dealer about towing.
What happens at the repair
At the dealer, a Super Duty technician replaces the old PTO assembly with a new pressure switch kit. The repair addresses the PTO pressure switch area, where oil can leak onto the thermal blanket near the exhaust. The remedy text says the recall began during September 2014 and that the work is free of charge. Because the remedy status is not marked available here, confirm parts and scheduling with the dealer before bringing in the truck. Parts and labor are covered under the recall once the dealer can perform the repair.
