13. Check the chain case oil seal for damage. If the oil seal is damaged, replace the chain case oil seal (see CHAIN CASE OIL SEAL INSTALLATION  ).
14. Remove all of the old liquid gasket from the chain case mating surfaces, bolts, and bolt holes.
15. Clean and dry the chain case mating surfaces.
16. Apply liquid gasket, P/N 08717-0004,08718-0001, 08718-0003, or 08718-0009, evenly to the engine block mating surface of the chain case.

    Install the component within 5 minutes of applying the liquid gasket.

    NOTE:

    • If you apply liquid gasket P/N 08718-0012, the component must be installed within 4 minutes.
    • If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply new liquid gasket.

17. Apply liquid gasket to the engine block upper surface contact areas (A) on the chain case and lower block upper surface contact areas (B) on the chain case.
18. Apply liquid gasket, P/N 08717-0004,08718-0001, 08717-0003, or 08718-0009, evenly to the oil pan mating surface of the chain case.

    Install the component within 5 minutes of applying the liquid gasket.

    NOTE:

    • If you apply liquid gasket P/N 08718-0012, the component must be installed within 4 minutes.
    • If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply new liquid gasket.

19. Install the new O-ring (A) on the chain case. Set the edge of the chain case (B) to the edge of the oil pan (C), then install the chain case on the engine block (D). Wipe off all of the excess liquid gasket on the oil pan and chain case mating surface.
    NOTE:

    • When installing the chain case, do not slide the bottom surface on the oil pan mounting surface.
    • Wait at least 30 minutes before filling the engine with oil.
    • Do not run the engine within 3 hours after installing the chain case.
