6. Remove timing case cover, front seal and gasket.
7. Cut off oil pan side gasket end tabs and front seal tabs until they are flush with front face of cylinder block.
8. Clean timing case cover, oil pan and cylinder block sealing surfaces, then remove front crankshaft seal from timing cover.
9. Apply sealing compound to both sides of timing case cover gasket, then position gasket onto cylinder block.
10. Cut off end tabs from replacement oil pan side gaskets, then cement tabs to corresponding points on oil pan.

Fig.11 Timing Case Cover Alignment Tool:

13. Install timing case cover alignment tool No. J-22248, or equivalent, into opening in timing case cover as shown, Fig.11
14. Install cover-to-cylinder block retaining bolts and oil pan-to-cover retaining bolts, noting the following:
a. Torque cover to block bolts to 5 ft. lbs.
b. Torque oil pan to cover 1/4 inch bolts to 9.5 ft. lbs. and 5/16 inch bolts to 13 ft. lbs.

15. Remove alignment tool, then position a new crankshaft seal onto tool. Ensure lip on seal faces outward. Apply a light coat of sealing compound to outside diameter of crankshaft seal, then coat crankshaft snout with engine oil.

Fig.12 Front Seal Installation:

16. Position alignment tool and seal over crankshaft snout, then insert installation tool J-9163-2 or equivalent into alignment tool as shown, Fig.12. Tighten nut on installation tool until alignment tool contacts timing cover. Remove tool.
17. Install vibration damper and pulley. Tighten vibration damper retaining nut to specifications. If engine is equipped with a serpentine drive belt, the pulley is integral with the vibration damper.
18. Install A/C compressor (if equipped) and alternator bracket assembly, then the cooling fan, hub, and fan shroud.
19. Install drive belts, then reconnect battery ground cable.
