Subaru 806733030 Oil Seal

Remove the flywheel or drive plate. Pry the rear Crankshaft Seal from the back of the block with a seal-removal tool, taking care not to nick the crankshaft seal surface. Clean the seal bore and ensure the seal mounting surface is free of burrs. Lubricate the new seal's inner lip with multi-purpose grease and the outer diameter with clean engine oil. Drive the new seal in place squarely using a seal driver, large socket, or a section of pipe that matches the outer diameter of the seal, ensuring it is driven to the original depth. Install the flywheel or drive plate, clutch assembly if equipped, and trans axle.

Remove the transaxle and, on manual transaxle models, the clutch assembly. Remove the flywheel/driveplate. Note the installation depth of the seal and then pry the rear Crankshaft Seal from the back of the block with a seal removal tool. Be very careful not to nick the crankshaft seal surface with the tool. Clean the seal bore and make sure the seal mounting surface is free of burrs. Lubricate the new seal's inner lip with multi-purpose grease, and the outer diameter with clean engine oil. Drive the new seal in place squarely with a seal driver, large socket, or section of pipe that's the same diameter as the outer diameter of the seal. Drive the seal to the original depth as noted during removal. Install the flywheel/driveplate, clutch assembly (if equipped) and transaxle.

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.

Next, unfasten the cable amongst the negative terminal of the battery. Further, the timing belt and crankshaft sprocket must be taken off. Gently loosen the seal from the cover using any of the following tools: seal puller or large screw driver, while trying to base it on some specific rules of bearing mind that if the area where the seal fits is scratched, gouged, or distorted it will lead to formation of an oil leak. Another way is to drill two 1/8-inch holes in the seal, taking the utmost care not to harm the seal housing or the crankshaft; then to screw two self-tapping screws into the holes and pull them with a slide hammer or self-locking pliers, going from side to side. Reduce the inner diameter of the bore to remove the old seal material and oxidation and place the new seal before the side with the lip faces the engine. It is recommended to coat this new seal with a small amount of oil at the outer radius to help installation, although it should not be too much oil. Using again a large socket and hammer, drive the seal into the bore of the shaft until it is seated correctly, that is from the outer face of the seal to the inner face until the seal comes into contact with the cover flange just as the previous seal. The rest of the process corresponds to the cleanness step by step and in the opposite order to the removal procedure.
