Crankshaft front oil seal — replacement
1. Remove the crankshaft pulley (see Crankshaft pulley/vibration damper — removal and installation).
2. Note how the seal is installed — the new one must be installed to the same depth and facing the same way. Carefully pry the oil seal out of the cover with a seal puller or a large screwdriver (see illustration). Be very careful not to distort the cover or scratch the crankshaft!
12.2 Carefully pry the old seal out of the timing chain cover don’t damage the crankshaft in the process
3. Apply clean engine oil or multi-purpose grease to the outer edge of the new seal, then install it in the cover with the lip (spring side) facing IN. Drive the seal into place with a seal driver or a large socket and a hammer (see illustration). Make sure the seal enters the bore squarely and stop when the front face is at the proper depth.
12.3 Drive the new seal into place with a large socket and hammer
4. Check the surface on the pulley hub that the oil seal rides on. If the surface has been grooved from long-time contact with the seal, the pulley should be replaced.
5. Lubricate the pulley hub with clean engine oil and reinstall the crankshaft pulley (see Crankshaft pulley/vibration damper — removal and installation).
6. Install the crankshaft pulley retaining bolt and tighten it to the torque listed in this Chapter’s Specifications.
7. The remainder of installation is the reverse of removal.
