Auto Parts Crankshaft seal Iveco Daily Fiat Ducato 1994-2006 2.5/2.8 front A

The crank seal is an important part of your engine. It is usually made of metal and rubber. Its purpose is to seal the end of the crankshaft. The crank seal keeps the oil in, while keeping dirt and debris out. The experienced Field Service Engineers at Lycoming indicate that a leaking crankshaft oil seal is frequently caused by a restricted breather or an oil-slinger clearance that is too tight. The leak might also be caused by a propeller defect which places an abnormal side load on the crankshaft oil seal.
