The Crankshaft Seal is among the key parts of Ford Ranger vehicles and it is situated at the front of the motor vehicle engine. Cranks and Seals are used variously in mechanical systems, for instance there is such a thing as a Crankshaft Seal in Ford Ranger vehicles which is located at the front of the vehicle engine and provides a barrier to prevent oil leakage from the crankcase. Made of a mixture of metal and rubber, this round seal is an important component when it comes to providing the necessary lubrication to the engine or decreasing friction and consequently wear of the engine's parts. In various years, 7 different types of Crankshaft Seal have been used on the Ford Ranger, mostly varying by material and in one case, design to improve the parts durability and potential performance. A Crankshaft Seal can become worn or damaged and high mileage vehicles are likely to develop oil leakage, hence the need for replacing the to enhance the efficiency of the engine. It is therefore clear that it is very important to perform a routine check up of the Crankshaft Seal of the Ford Ranger to ensure that it is in good working condition to aid the functioning of the Engine.
