2. Remove the crankshaft pulley.
3. Remove the timing belt (see Audio system).
4a. Remove the outer crankshaft belt guide.
4b. Remove the crankshaft gear.
4c. On models not equipped with a crankshaft vibration sensor, remove the inner belt guide (see accompanying illustration).
Note. If the engine is equipped with a crankshaft vibration sensor, the inner guide will be built into the gear wheel.
5. Gently prying with a special tool or a large screwdriver, remove the old oil seal from its socket (see accompanying illustration). Try not to leave scratches and scuffs on the surface of the shaft pin or oil pump housing - the presence of such defects will lead to a quick failure of the new oil seal. 6. Clean the inside surfaces of the gland seat. Lubricate the outer edge of the new oil seal with clean engine oil or multipurpose grease. Using a socket head of the appropriate size as a mandrel, or a piece of pipe of a suitable diameter, plant a new oil seal in its socket. The mandrel should rest only on the hard outer edge of the end face of the stuffing box. After seating the oil seal, make sure that the spacer spring does not pop out of its groove.
7. Install the inner timing belt guide, crankshaft sprocket, then the outer guide. Install the timing belt next (see Audio system).
8. Lubricate the crankshaft pulley hub with engine oil or multipurpose grease, then fit the pulley onto the crankshaft journal. Further installation is carried out in the reverse order to the dismantling of the components.
9. Start the engine and check for signs of oil leaks.
