7. Make sure again that the timing marks are aligned and remove the timing belt as described above.
8. Lock the camshaft sprocket and unscrew the mounting bolt. Remove the sprocket and pull out the key with nippers.
9. If you are using a special puller, place it on the seal, grab the seal and use the puller to unscrew the fastening bolt. Without using a puller, you can screw a self-tapping screw into the seal and pull it out with pliers, a screwdriver or other suitable tool.
10. Check whether the sealing lip fits tightly to the working surface of the camshaft. If not, push the oil seal 1.5 mm deeper so that the sealing lip is installed on the new working surface.
11. Lubricate the outside of the new seal with engine oil and push it on using a puller. It can remain on the outside of the seal while the bolt is screwed into the camshaft (see illustration).
