  - : At cylinder head upper face side in each bank.
  Camshaft dowel pin (exhaust side)
  - : At cylinder head upper face side in each bank.
  Crankshaft key
  - : At cylinder head side of right bank.
CAUTION: Hole on small dia. side must be used for intake side dowel pin hole. Do not misidentify (ignore big dia. side).
Install timing chains (secondary) and camshaft sprockets as follows:
CAUTION: Mating marks between timing chain and sprockets slip easily. Confirm all mating mark positions repeatedly during the installation process.

2. Install timing chains (secondary) and camshaft sprockets.
  - Align the mating marks on timing chain (secondary) (gold link) with the ones on intake and exhaust camshaft sprockets (punched), and install them.
    NOTE:
    Mating marks for intake camshaft sprocket are on the back side of camshaft sprocket (secondary).
    
    There are two types of mating marks, circle and oval types. They should be used for the right and left banks, respectively.
    Right bank: Use circle type.
    
    Left bank: Use oval type.
  - Align dowel pin and pin hole on camshafts with the groove and dowel pin on sprockets, and install them.
  - On the intake side, align pin hole on the small diameter side of the camshaft front end with dowel pin on the back side of camshaft sprocket, and install them.
    
    Fig 9: Installing Timing Chains (Secondary) & Camshaft Sprockets

  - On the exhaust side, align dowel pin on camshaft front end with pin groove on camshaft sprocket, and install them.
  - In case that positions of each mating mark and each dowel pin are not fit on mating parts, make fine adjustment to the position holding the hexagonal portion on camshaft with wrench or equivalent.
  - Mounting bolts for camshaft sprockets must be tightened in the next step. Tightening them by hand is enough to prevent the dislocation of dowel pins.
  - It may be difficult to visually check the dislocation of mating marks during and after installation. To make the matching easier, make a mating mark on the top of sprocket teeth and its extended line in advance with paint.

2. Install timing chain (primary).
  - Install timing chain (primary) so the mating mark (punched) on camshaft sprocket is aligned with the yellow link on timing chain, while the mating mark (notched) on crankshaft sprocket is aligned with the orange one on timing chain, as shown in the figure.
  - When it is difficult to align mating marks of timing chain (primary) with each sprocket, gradually turn camshaft using wrench on the hexagonal portion to align it with the mating marks.
  - During alignment, be careful to prevent dislocation of mating mark alignments of timing chains (secondary).
