    Timing chain tension guide bolts : 21.6 N.m (2.2 kg-m, 16 ft-lb) 

  11. Position the crankshaft so No. 1 piston is set at TDC on the compression stroke.
    • Make sure that the dowel pin hole, dowel pin and crankshaft key are located as shown. Camshaft dowel pin hole (intake side): 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 RH bank.

      CAUTION: Hole on small diameter side must be used for intake camshaft sprocket dowel pin. Do not misidentify (ignore big diameter side).
  12. Install the secondary timing chains and camshaft sprockets.
    CAUTION: Matching marks between the timing chain and sprockets slip easily. Confirm all matching mark positions repeatedly during the installation process.
    • Push the sleeve of the secondary chain tensioner and keep it pressed in with a stopper pin.
      Fig 11: Installing Secondary Timing Chains
      G00572436Courtesy of NISSAN MOTOR CO., U.S.A.
    1. Align the matching marks on the secondary timing chain (gold link) with the ones on the intake and exhaust sprockets (stamped), and install them.
      • Matching marks for the intake sprocket are on the back side of the secondary sprocket.
      • There are two types of matching marks, round and oval types. They should be used for the RH and LH banks, respectively. RH bank: use round type. LH bank: use oval type.
        • Fig 12: Aligning Matching Marks On The Secondary Timing Chain
        G00572437Courtesy of NISSAN MOTOR CO., U.S.A.
    2. Align The Dowel Pin And Pin Hole On The Camshaft With The Groove And Dowel Pin On The Sprocket, And Install Them.
      • On The Intake Side, Align The Pin Hole On The Small Diameter Side Of The Camshaft Front End With The Dowel Pin On The Back Side Of The Camshaft Sprocket, And Install Them.
      • On The Exhaust Side, Align The Dowel Pin On The Camshaft Front End With The Pin Groove On The Camshaft Sprocket, And Install Them.
      • Camshaft Sprocket Bolts Must Be Tightened In The Next Step. Tightening Them By Hand Is Enough To Prevent The Dislocation Of The 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 Sprocket Teeth In Advance With Paint.
