Take out the Crankshaft rear main oil seal with great care to avoid scratching the sealing surface of the Crankshaft. Pulling out a new style seal with the lip facing in, place a flat-bladed or a similar tool between the sealing lip of the seal and the outer casing at an angle and gently pry the seal out toward the center of the Crankshaft. To remove an old style seal with the lip inserted make sure to insert the tool at the area outside the outer seal casing but inside the engine block casting pressing down and out to remove the seal.

Lastly, ensure that the seal is well seated and eliminated using a flat-bladed screwdriver to remove the left-handed and right-handed screws present in securing the mandrel with the Crankshaft hub, take off the mandrel from the Crankshaft hub.
