Crankshaft pulley and front oil seal — replacement
1. Disconnect the cable from the negativebattery terminal (see Engine electrical systems). Loosen the right front wheel lug nuts. Raise the vehicle and support it securely on jack stands. Remove the wheel and the splash shield from below the engine compartment.
2. Remove the drivebelt (see Tune-up and routine maintenance).
3. nscrew the crankshaft pulley bolt. Aspecial tool that engages with the recessed hex in the pulley opening is available to prevent the crankshaft from turning while unscrewing the bolt. If you can’t obtain one of these tools, remove the flywheel/drive plate inspection cover and wedge a screwdriver into the starter ring gear teeth. Slip the pulley off the crankshaft.
Note: The crankshaft pulley bolt can be incredibly tight; it may be necessary to use animpact tool if the pulley holding tools are not used.
4. Carefully pry the seal out of the housingwith a seal removal tool or a screwdriver (see illustration). Don’t scratch the seal bore or damage thecrankshaft in the process (if the crankshaft is damaged, the new seal will end up leaking).
i.4 Carefully pry the oil seal out with a removal tool or a screwdriver — don’t nick or scratch the crankshaft or oil pump housing or the new seal will leak
5. Clean the bore in the seal housing andcoat the outer edge of the new seal with engine oil or multi-purpose grease. Using a seal driver or a socket with an outside diameter slightly smaller than the outside diameter of the seal, carefully drive the seal into place with a hammer until the inner edge of the seal is 7/32 to 15/64-inch (5.55 to 5.95 mm) deep. If a socket is not available, a short section of a large diameter pipe will work. Check the seal after installation to be sure the spring did not pop out.
6. Lubricate the lip of the seal with a thinfilm of engine oil or multi-purpose grease, then lubricate the crankshaft bolt with oil between the head of the bolt and the washer and the first few threads of the oil ONLY and install the crankshaft pulley.
Note: The crankshaft pulley has flats on the sleeve that must be aligned with the inner oil pump gear.
7. The remainder of installation is thereverse of removal.
8. Run the engine and check for leaks.
