FEL-PRO Engine Crankshaft Seal Kit P/N:BS 40796
FEL PRO GASKETS BS 40743 rear crankshaft seal kit for the 2011-2020 Ford F-250 Super Duty V8 6.7L and other vehicles seals the crankshaft where it leaves the engine. The seal body stays still while the crankshaft turns inside it.
Oil seepage or wetness at the rear of the engine can mean the seal is leaking. Before you replace the engine crankshaft seal kit, rule out other oil leaks nearby, since oil from higher up can run down and look like a bad crankshaft seal.
This kit is listed for a wide range of Ford Super Duty models, including the 2011-2020 Ford F-350 Super Duty V8 6.7L and the 2011-2020 Ford F-450 Super Duty V8 6.7L, and each takes one kit. It meets or exceeds all original equipment specifications. If your truck is not named here, look up its year and engine in the "Vehicles it fits" section.
