Chrysler 4777086 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. Rotate the crankshaft counterclockwise until the crankshaft sprocket is three notches BTDC to prevent engine damage if the camshaft sprocket rotates during sprocket bolt removal. Hold the camshaft sprocket and remove the camshaft sprocket bolt; using a strap-type pulley holder tool is recommended for this task. If unavailable, two large screwdrivers can be used to pry the sprocket off the camshaft, or the valve cover can be removed to access the camshaft wrenching flats. Next, remove the idler pulley and the bolts holding the rear cover to the engine block and cylinder head, then take off the rear cover. Pry out the camshaft oil seal carefully to avoid scratching the bore or damaging the camshaft, as damage will cause the new seal to leak. Clean the bore and coat the outer edge of the new seal with engine oil or multi-purpose grease, lubricating the seal lip. Use a socket with an outside diameter slightly smaller than the seal and a hammer to gently tap the new seal into place with the spring side facing inward, ensuring it is flush with the face of the cylinder head. If a socket isn't available, a short section of pipe can be used instead. If space is limited, fabricate a seal installation tool from a piece of pipe, a bolt, and a large washer to press the seal into place. Afterward, install the rear timing belt cover and idler pulley. Install the camshaft sprocket, ensuring the pin in the camshaft aligns with the hole in the sprocket, then hold the camshaft sprocket and tighten the sprocket bolt to the specified torque. Finally, reinstall the timing belt and run the engine to check for oil leaks at the camshaft seal.
