Removal and Installation: Installation

• Install them in the same position from which they were removed.

• The distinction between the intake and exhaust camshafts is in a difference of shapes of the back end:

  Intake (B): Signal plate for the camshaft position sensor (PHASE)

  Exhaust (A): Cone end shape

• Install them by lining up the mating marks on each camshaft sprocket with the ones painted on the timing chain during removal.
• Before installation of chain tensioner, it is possible to re-match the marks on timing chain with the ones on each sprocket.
  CAUTION:

  • Aligned mating marks could slip. Therefore, after matching them, hold the timing chain in place by hand.
  • Before and after installing chain tensioner, check again to make sure that mating marks have not slipped.
