Remove the crankshaft pulley. First, delicately extract the threaded part of the timing chain cover using a screwdriver or seal removing tool;. Second, you should remove the lip on the crankshaft seal. If using an ordinary metallic screwdriver, it is wise to cover the tip of the screwdriver to avoid inexperienced scratching of such housing bore or hasty harming of the crankshaft which may lead to leakage with the new seal that has been fixed. Clean the bore in the timing chain cover, applying engine oil or multi-purpose grease, to the lip and outer edges of a new seal. Using a seal driver or placing a socket having a diameter slightly less than the diameter of the seal into it, gently force the new seal into its seat with a hammer taking care to see that the seal is placed squarely and flush with the surface of of the timing chain cover. Do this and you will be sure that your seal is in the right position and the spring installed as well. Replace the crankshaft pulley and fasten the bolt tightening it to the standard torque. Last but not the least, start the engine and look for the oil traces at the front seal.
