Crankshaft front oil seal – replacement
1. Remove the crankshaft pulley (Crankshaft pulley – removal and installation).
2. Use a screwdriver or hook tool to carefully pry out the seal (see illustration).
7.2 Use a hook tool to pry the seal from the timing chain cover
Note: Be careful not to damage the oil pump cover bore where the seal is seated, or the nose and sealing surface of the crankshaft.
3. Another method for removing the seal is to drill a small hole on each side of the seal and place a self-tapping screw in each hole (see illustration). Use these screws as a means of pulling the seal out without having to pry on it.
7.3 Another way of removing an old oil seal is to screw a self- tapping screw partially into the seal, then use pliers as a lever to pull it from the engine
4. If the seal is being replaced when the timing chain cover is removed, support the cover on top of two blocks of wood and drive the seal out from the backside with a hammer and punch.
Caution: Be careful not to scratch, gouge or distort the area that the seal fits into or a leak will develop.
5. 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, then stop when the front face is at the proper depth.
7.5 Drive the seal squarely into the cover using a socket and hammerr
6. 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 will have to be replaced.
7. Lubricate the pulley hub with clean engine oil, then install it (Crankshaft pulley – removal and installation).
