Camshaft Removal
• Remove:
   Cylinder Head Cover (see Cylinder Head Cover Re-
     moval)
     Crankshaft Sensor Cover (see Crankshaft Sensor Re-
     moval in the Electrical System chapter)
•   Using a wrench on the timing rotor bolt [A], turn the crank-
    shaft clockwise until the line [B] (TDC mark for #1, 4 pis-
    tons) on the timing rotor is aligned with the mating surface
    [C] of the crankcase.

• Remove   the camshaft chain tensioner (see Camshaft
  Chain Tensioner Removal).
• Loosen  the upper camshaft chain guide bolts and
  camshaft cap bolts gradually and evenly as shown se-
    quence [1 ∼ 20], and remove them.
•   Remove:
      Upper Camshaft Chain Guide [A]
      Camshaft Caps [B]
      Camshafts [C]

                            NOTICE
    The crankshaft may be turned while the camshafts
    are removed. Always pull the chain taut while turn-
    ing the crankshaft. This avoids kinking the chain
    on the lower (crankshaft) sprocket. A kinked chain
    could damage both the chain and the sprocket.
