The crankshaft pulley bolt has to be loosened and the pulley can then be slid off the engine. Gradually remove the seal from the cover using a seal removing tool or a large screwdriver being keen not to scratch the seal bore or the cranks shaft. It is also prohibited to scratch or gouge the area of the sealing component or to distort it in any way since that would lead to an oil leak. Remove the debris of the old seal and corrosion from the bore before placing the new seal in the bore with the inward facing side being on the side that has the spring. A small quantity of oil can be put at the outer ring of the new seal for easy fitting but should not be excessive. Screw the seal into the bore using a seal driver or a large socket and hammer to the extent that the selected socket diameter is equal to the outside diameter of the seal and the new seal is pressed into the cover flange. Grease the seal lips with the engine oil and replace the crankshaft pulley. The other steps of installation are the reverse of those of removal. After the installation has been done the engine should be turned on to see if there is any sign of oil leakage.

The first step is to remove the crankshaft pulley from the engine.

Use a punch and hammer to drive the old seal out of the housing, ensuring not to damage the seal bore by wrapping the tip of the punch with tape.

Support the cover on two blocks of wood and drive the seal out from the backside using a hammer and punch, ensuring not to scratch or distort the area where the seal fits to prevent leaks.

An alternative method involves drilling small holes on each side of the seal and inserting self-tapping screws, which can then be used with pliers to pull the seal out without prying.

The first step is to remove the crankshaft pulley and the timing belt.

Install the crankshaft balancer, with the remainder of the installation being the reverse of the removal process.

The outlined procedure should be followed while using the appropriate bolt torque value.

Replacing the rear main oil seal requires the removal of the transaxle and driveplate.

It is advisable to place cardboard between the radiator and the vibration damper for protection during removal and installation.

While pressing the oil seal housing evenly, tighten the oil seal housing retainer bolts to the specified torque, ensuring the housing is flush with the oil pan mating surface of the engine to prevent oil leaks.

A 1/4-inch bead of RTV sealant should be applied where the lower corners of the seal retainer meet the oil pan.

A hammer and punch are used to tap the dowel pin out of the crankshaft, driving it into the hollow, threaded area of the crankshaft snout for extraction with a small magnet.

Lubricate the seal lips with engine oil and reinstall the crankshaft pulley.

Begin by removing the transmission and the oil pan, followed by the driveplate.

Install the seal in the cover with the lip facing inward, using a large socket and hammer to drive it into place squarely, stopping when the front face is at the proper depth. A piece of pipe can be used if a large socket is unavailable.

Use a seal driver to tap the seal into place to ensure it doesn't become tilted.

It is important to read the procedure carefully before starting.

The rear main seal and housing are serviced as one complete assembly.

Use a screwdriver wrapped with tape to pry out the seal, being careful not to gouge or nick the housing.

After that, unbolt the seal retainer from the engine block and slide the retainer and seal off the end of the crankshaft.

The rear main seal housing can be removed to change the seal, but this requires the removal of the oil pan. If the housing is removed, it should be placed on two blocks of wood, and a small punch can be used to drive out the old seal.

The new seal should be pressed squarely into the housing bore. If a press is unavailable, you can sandwich the housing and seal between two smooth pieces of wood and use a large vise, or lay the housing on a workbench and drive the seal in with a block of wood and hammer.

Install the driveplate or flywheel and clutch, then install the transaxle.

Install the new seal in the cover with the lip facing inward, driving it into place with a seal driver or a large socket and hammer, ensuring it enters squarely and is at the proper depth.

Place the retainer in a bench vise and pry out the old seal using a screwdriver.

Use a large deep socket and gently tap it with a hammer; if a large socket isn't available, a piece of pipe of the proper diameter will also work.

Drive the new seal in using a seal driver or a large deep socket and a hammer, ensuring it is installed to the same depth as the old one.

Apply a 1/4-inch bead of RTV sealant where the lower corners of the seal retainer meet the oil pan.

Install the cover and all of the bolts. Hand tighten a couple of the bolts to secure it in position. The seal alignment tool must be in place. Tighten the bolts evenly to the specified torque. Make sure that the seal alignment tool is correctly located while this is done, then remove the tool. The remainder of installation is the reverse of removal.

Clean the bore and position the new seal with the seal lip facing inward. Drive the seal into the bore with a seal driver or a large socket and hammer until it's completely seated.

The new seal should be driven squarely into the seal bore and flush with the rear of the engine block.

To remove the rear seal, carefully drill a few holes through the seal without touching the crankshaft. Then, insert sheet metal or wood screws into the holes and use a slide hammer, pry bar, or claw hammer to pull the seal out.

Carefully pry the oil seal out with a screwdriver or seal removal tool, taking care not to scratch the crankshaft.

Drive the seal into the bore with a seal driver or a large socket and hammer until it's completely seated.

Before installing a new seal, it is important to apply clean engine oil or multi-purpose grease to the outer edge of the seal. This will help with proper lubrication.
