Mopar 4273275 Oil Seal

Do not rotate the camshaft(s) or crankshaft when the timing belt is removed or damage to the engine may occur. Begin by removing the timing belt. Next, detach the crankshaft timing belt sprocket from the crankshaft using a bolt-type gear puller, and remove the Woodruff key from the crankshaft keyway. From below the right inner fender, carefully pry the seal out of its bore, taking care to avoid damaging the oil pump assembly, the crankshaft, and the seal bore. Clean and inspect the seal bore and sealing surface on the crankshaft; minor imperfections can be removed with emery cloth, but if a groove is worn in the sealing surface, a new seal may not stop the leak. Lubricate the new seal with engine oil and use a hammer and the appropriate size socket to drive the seal into the bore until it is flush with the oil pump housing. Install the Woodruff key and the crankshaft timing belt sprocket with the word FRONT facing out on the crankshaft. The crankshaft timing sprocket must be installed with special tool 6792 to ensure correct timing belt tracking; incorrect installation may lead to timing belt damage. Finally, reinstall the remaining components in reverse order of removal and tighten the crankshaft pulley bolt to the specified torque. Start the engine and check for oil leaks.
