How to install the rear crankshaft seal in a four-cylinder engine on Ford Fusion?

The one-piece rear Crankshaft Seal is pressed into the rear Crankshaft Seal carrier mounted at the rear of the block. Begin by removing the transaxle and the flywheel/driveplate, followed by the oil pan. Unbolt the Crankshaft Seal and carrier, then clean the mating surface for the Crankshaft Seal carrier on the cylinder block and the crankshaft, ensuring to carefully remove and polish any burrs or raised edges on the crankshaft that may have caused the seal to fail. Lightly coat the inside lip of the new seal with clean engine oil and use a thin, durable two-inch wide plastic strip or a cut two-liter plastic beverage bottle around the inside circumference of the seal to act as a liner for installation. With the plastic seal liner or tool in place, carefully move the new carrier (with seal factory-installed) into position by sliding it onto the contact surface of the crankshaft. Install the Crankshaft Seal carrier bolts and finger tighten them while holding the carrier in place, ensuring the bottom of the seal carrier aligns precisely with the bottom edge of the engine block for a flush surface before tightening the carrier mounting bolts. Carefully remove the plastic liner or tool to allow the new seal to contact the crankshaft mating surface correctly, then tighten the Crankshaft Seal carrier to the specified torque using the proper sequence. The remainder of the installation follows the reverse order of removal.

Ford Fusion Crankshaft Seal

Crankshaft Seal is an object in Ford Fusion car located at front end of the engine to obstruct the leakage of the engine oil from the crank case. Made from metal and rubber, this round seal is usually cylindrical in shape and its function is to retain oil for parts that are critical to the engine, so as to reduce the amount of wear due to friction. In the course of years, number of designs of Crankshaft Seal may have been installed in the various types of Ford Fusion Models but the fundamental uses will remain the same. Damaged or worn Crankshaft Seal can cause noticeable signs especially in cases where the kilometers on the car are high thus showing that it is high time to replace this component if efficiency of the engine is to be improved. The Ford Fusion has a Crankshaft Seal which needs to be checked and replacing every time you change your oil so as to avoid continuous oil leaks and non-functioning of the automobile's engine.

Q: How to install the rear crankshaft seal in a four-cylinder engine on Ford Fusion?
A:
The one-piece rear Crankshaft Seal is pressed into the rear Crankshaft Seal carrier mounted at the rear of the block. Begin by removing the transaxle and the Flywheel/driveplate, followed by the Oil Pan. Unbolt the Crankshaft Seal and carrier, then clean the mating surface for the Crankshaft Seal carrier on the cylinder block and the crankshaft, ensuring to carefully remove and polish any burrs or raised edges on the crankshaft that may have caused the seal to fail. Lightly coat the inside lip of the new seal with clean engine oil and use a thin, durable two-inch wide plastic strip or a cut two-liter plastic beverage bottle around the inside circumference of the seal to act as a liner for installation. With the plastic seal liner or tool in place, carefully move the new carrier (with seal factory-installed) into position by sliding it onto the contact surface of the crankshaft. Install the Crankshaft Seal carrier bolts and finger tighten them while holding the carrier in place, ensuring the bottom of the seal carrier aligns precisely with the bottom edge of the engine block for a flush surface before tightening the carrier mounting bolts. Carefully remove the plastic liner or tool to allow the new seal to contact the crankshaft mating surface correctly, then tighten the Crankshaft Seal carrier to the specified torque using the proper sequence. The remainder of the installation follows the reverse order of removal.
