Nissan 12279-4Z001 Seal-Oil,CRANKSHAFT Rear

Remove the transaxle and then take out the flywheel/driveplate. Use a screwdriver wrapped with tape to pry the Crankshaft Seal out, being careful not to gouge or nick the housing. Lubricate the crankshaft seal journal and the lip of the new Crankshaft Seal with multi-purpose grease. Install the Crankshaft Seal with the seal lip toward the engine and the dust seal toward the transmission. Tap the Crankshaft Seal into place using a seal driver to ensure it doesn't become tilted. Install the Crankshaft Seal so that its rear edge is flush with the face of the engine block or up to 0.020 inch recessed. The remaining steps are the reverse of removal. Reconnect the battery and perform the necessary re-learn procedures.

The transmission must be removed from the vehicle for this procedure. Carefully pry out the old Crankshaft Seal out of the retainer with a seal removal tool or screwdriver. Pry the seal out very carefully with a seal removal tool or screwdriver - if the crankshaft is damaged the new seal will leak! Apply multi-purpose grease to the crankshaft seal journal and the lip of the new Crankshaft Seal. Preferably, a seal installation tool should be used to press the new seal into place. If the proper seal installation tool is unavailable, use a large socket, section of pipe or a blunt tool and carefully drive the new Crankshaft Seal into place. If you don't have a seal installation tool, use a blunt tool (such as a brass punch) to carefully work the edge of the seal evenly into the bore and around the crankshaft. The lip is stiff so carefully work it onto the seal journal of the crankshaft. Don't rush it or you may damage the seal. Install the seal squarely and only until flush with the back of the seal plate, no further. The remaining steps are the reverse of removal.

Remove the transmission. Remove the flywheel/driveplate. Remove the rear Crankshaft Seal retainer from the block by unbolting the rear Crankshaft Seal retainer from the engine block and oil pan. Scrape any sealant or gasket material from the retainer, oil pan and the block. Position the seal and retainer assembly between two wood blocks, to evenly support the aluminum housing, and drive the old seal out with a hammer and punch. A screwdriver can also be used to pry the seal out, being careful not to gouge or nick the housing during seal removal. Place the new seal squarely on the retainer and drive it into the retainer with a wood block or a section of pipe slightly smaller in diameter than the outside diameter of the seal. Lubricate the crankshaft seal journal and the lip of the new seal with multi-purpose grease. Apply a continuous 1/8-inch bead of RTV sealant around the perimeter of the seal retainer. Also apply sealant to the bottom of the retainer (oil pan mating surface). Slowly and carefully push the seal onto the crankshaft. The seal lip is stiff, so work it onto the crankshaft with a smooth object such as the end of a socket extension as you push the retainer against the block. Install and tighten the retainer bolts securely. The remaining steps are the reverse of removal.

For this procedure the transaxle has to be unbolted from the car and supporting from above is the engine hoist or the three bar support when you will be working under the car with the transaxle out. First, using seal removal tool or screw driver gently try to remove the old Crankshaft Seal from the retainer touching the crankshaft it's that sensitive maybe maybe because of that the new seal will develop a leakage. Next, spread multi-purpose grease to the crankshaft seal journal and the sides of the new seal lip. It is preferred to employ a seal installation tool to achieve the installation of the new seal; in the absence of this implement, a large socket, pipe segment or, a blunt object must be used to gently tap the new seal into place. Make sure that lip is guided on to the seal journal of the crankshaft in a gentle and slow fashion, since this is likely to disrupt the seal. Screw the installed seal right into place but no deeper than so that the flange of the seal is in line with the back of the seal plate. The last few steps are basically those of the reversibility of the removal process outlined above.

The transmission must be removed from the vehicle for this procedure. Carefully pry the old Crankshaft Seal out with a seal removal tool or screwdriver, ensuring not to damage the crankshaft, as any damage may cause the new seal to leak. Apply multi-purpose grease to the crankshaft seal journal and the lip of the new Crankshaft Seal. It is preferable to use a seal installation tool to press the new seal into place, taking care to work the stiff lip onto the seal journal of the crankshaft without rushing, as this may damage the seal. Install the seal squarely and only until it is flush with the back of the seal retainer, no further. The remaining steps involve reversing the removal process.

Remove the transaxle and the flywheel/driveplate. Use a screwdriver wrapped with tape to pry out the Crankshaft Seal, being careful not to gouge or nick the housing. Lubricate the crankshaft seal journal and the lip of the new Crankshaft Seal with multi-purpose grease. Install the Crankshaft Seal with the seal lip toward the engine and the dust seal toward the transaxle. Tap the Crankshaft Seal into place using a seal driver to ensure it doesn't become tilted. Install the Crankshaft Seal so that its rear edge is flush with the face of the engine block, or up to 0.019 inch recessed. The remainder of installation is the reverse of removal. Reconnect the battery and perform the necessary re-learn procedures.

Apply a bead of RTV sealant to the sealing surface of the new retainer and lightly lubricate the oil seal lip with clean engine oil.

Remove the crankshaft pulley and carefully pry the seal out of the cover using a seal removal tool or a large screwdriver, taking care not to scratch, gouge, or distort the area where the seal fits to prevent oil leaks.

Using a seal driver or a socket slightly smaller than the seal's outside diameter, carefully drive the new seal into place, ensuring it is installed squarely and to the same depth as the original, while checking that the garter spring remains in place.

Complete the installation by reversing the removal steps, then run the engine and check for any oil leaks.

Prior to reinstalling the crankshaft pulley, lubricate the seal lips with engine oil.

The old seal can be removed using a hammer and punch by driving it out from the back side.

Next, take out the right inner wheel well and the drivebelts.

Before installation, apply a thin coat of multi-purpose grease to the inside of the seal. Fabricate a seal installation tool with a short length of pipe of equal or slightly smaller outside diameter than the seal itself. File the end of the pipe that will bear down on the seal until it's free of sharp edges. You'll also need a long bolt of the same thread pitch as the crankshaft pulley bolt and a large washer, slightly larger in diameter than the pipe, on which the bolt head can seat.
