Take off the belt guard and then the crankshaft pulley from the engine. Prepare the back of the seal and lift the cover while still flexible by using a seal removal tool or a screw driver but ensure you do not harm the seat bore or the crankshaft. One must not scratch, cut or deform in any manner the part where the seal dove into as this could lead to oil leakage. Scrape out the bore to remove any of the material of the old seal together with the corrosion and position the new seal in the bore with the lip turned inwards towards the engine. Before installing, it is recommendable to apply a small amount of oil on the outer fringes and inner rim of the new seal. Install the seal into the bore utilizing a seal driver or a large socket and hammer until such time that the seal is fully seated in the cover flange of the motor. Check the area of the damper that comes into contact with the oil seal ; if the contact surface now has grooves testify to long-term contact, it may be possible to take a press-on sleeve to restore the sealing. This sleeve can be hammered into place with a hammer and a wooden block and is usually available across auto parts stores. Apply engine oil to the seal lips and fit the crankshaft pulley back into place, fasten the bolt and torque it to the right amount. Reverse the removal process to complete the installation; after that, start the engine and inspect for leakages of oil.

The remaining steps involve reversing the removal process.
