  8.  
  9. Apply new engine oil to the threads of the cam chain tensioner mounting bolt. Tighten the bolt to 16 ft. lbs. (22 Nm).
  10.  
  11. Install the cam chain tensioner and cam chain guide. Tighten the mounting bolts to 9 ft. lbs. (12 Nm).
  12.  
  13. Install the cam chain tensioner slider, and tighten the bolt loosely.
  14.  
  15. Apply new engine oil to the sliding surface of the cam chain tensioner slider.
  16.  
  17. Rotate the cam chain tensioner slider clockwise to compress the cam chain tensioner, and install the remaining bolt, then tighten the bolts to 9 ft. lbs. (12 Nm).
  18.  
  19. Check the chain case oil seal for damage If the oil seal is damaged, replace the chain case oil seal.
  20.  
  21. Remove the old liquid gasket from the chain case mating surfaces, the bolts, and the bolt holes.
  22.  
  23. Clean and dry the chain case mating surfaces.
  24.  
  25. Install the CKP pulse plate on the crankshaft.
  26.  
  27. Apply liquid gasket evenly to the engine block mating surface of the chain case.
  28.  
  29. Install the component within 5 minutes of applying the liquid gasket.
    1. Apply a 1.5 mm wide bead of liquid gasket along the broken lines.
    2.  
    3. Apply a 3.0 mm wide bead of liquid gasket to the engine block upper surface contact areas on the chain case.
    4.  

  30.
