Subaru 806733030 Oil Seal

Disconnect the cable from the negative terminal of the battery. Remove the timing belt and crankshaft sprocket. Carefully pry the seal out of the cover with a seal puller or a large screwdriver. An alternative method is to drill two 1/8-inch holes in the seal, being careful not to hit the seal housing or crankshaft. Screw two self-tapping screws into the holes and pull on them, alternating side to side, with a slide hammer or self-locking pliers on the screws. Clean the bore to remove any old seal material and corrosion. Position the new seal in the bore with the seal lip (usually the side with the spring) facing IN (toward the engine). A small amount of oil applied to the outer edge of the new seal will make installation easier - but don't overdo it! Drive the seal into the bore with a large socket and hammer until it's completely seated. Select a socket that's the same outside diameter as the seal and make sure the new seal is pressed into place until it bottoms against the cover flange, to the same depth as the original seal. Install the sprocket and timing belt. The remainder of installation is the reverse of removal.
