Remove the crankshaft pulley. Pry the old oil seal out with a seal removal tool or a screwdriver. Be very careful not to nick or otherwise damage the crankshaft in the process. Wrap the screwdriver tip with vinyl tape to protect the crankshaft. Apply a thin coat of ATV-type sealant to the outer edge of the new seal. Lubricate the seal lip with moly-base grease or clean engine oil. Place the seal squarely in position in the bore and drive it into place. If you don't have the special, carefully tap the seal into place with a large socket or piece of pipe and a hammer. The outer diameter of the socket or pipe should be the same size as the seal outer diameter. Make sure the seal is seated completely in the bore. Install the crankshaft pulley. Reinstall the remaining parts in the reverse order of removal. Start the engine and check for oil leaks at the seal.
