Remove the crankshaft pulley and note the installation depth and orientation of the seal, ensuring the new one is installed the same way. Carefully pry the oil seal out of the cover using a seal puller or a large screwdriver, wrapping electrician's tape around the screwdriver tip to prevent damage to the crankshaft. Cut the lip of the seal with a utility knife to facilitate removal, taking care not to distort the cover or scratch the crankshaft. Apply clean engine oil or multi-purpose grease to the outer edge of the new seal, then install it in the cover with the lip facing inward. Drive the seal into place using a seal driver or a large socket and hammer, ensuring it enters the bore squarely and stops at the correct depth. Check the surface on the pulley hub where the oil seal makes contact; if it is grooved, a press-on sleeve may be available to renew the sealing surface, which can be pressed into place with a hammer and a block of wood. Lubricate the pulley hub with clean chassis grease and reinstall the crankshaft pulley. Install the crankshaft pulley retaining bolt and tighten it to the specified torque, with the remainder of the installation being the reverse of removal.
