NOTE:
  • This illustration shows the relationship between the mating mark on each timing chain and on the corresponding sprocket with the components installed.
  • The mating mark (circle) and mating mark (oblong) for the timing chain (secondary) are located on the rear of the camshaft sprocket (INT) and camshaft sprocket (EXH).
  1. Install timing chain tensioners (secondary) with a new O-ring and the stopper pin attached.
    CAUTION: Do not reuse O-ring.
  2. Check that dowel pin (A) and crankshaft key (1) are located as shown, below. (No. 1 cylinder at compression TDC)

  3. Install timing chain (secondary) and camshaft sprockets (INT and EXH) as follows:
    CAUTION: Mating marks between timing chain and sprockets slip easily. Confirm all mating mark positions repeatedly during the installation process.
    1. Push plunger of timing chain tensioner (secondary) and keep it pressed in with stopper pin (A).

      NOTE: Bank 1 and Bank 2 shown (rear view).
      • Align the mating marks on timing chain [secondary (pink link)] with the mating marks on camshaft sprockets (INT and EXH), and install them.
      • Align dowel pin on camshafts with the groove on sprockets, and install them.
      • Tighten the bolts for the camshaft sprockets by hand enough to prevent the dowel pins from falling out of the grooves.
      • 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 (A) on the top of sprocket teeth and its extended line with paint.

    • Secure the camshaft using a suitable tool at the hexagonal portion to tighten the bolts.
  5. Remove stopper pins from timing chain tensioners [secondary (1)].

    NOTE: Install the chamfered side (A) of the oil pump drive chain sprocket (2) first.
  8. Rotate oil pump drive chain tensioner (1) counterclockwise with a suitable tool and install oil pump drive chain (2) onto oil pump gear.

    • Make sure the mating marks on the crankshaft sprocket face the front of the engine.
  11. Install the timing chain (primary).
    GNSAWBIA3372Z-372Courtesy of NISSAN NORTH AMERICA, INC.
    • Install timing chain (primary) so the mating mark (B) on camshaft sprocket (1) is aligned with the blue link (A) on the timing chain, while the mating mark (C) on the crankshaft sprocket (2) is aligned with the pink link (D) on the timing chain, as shown, above.
    • When it is difficult to align mating marks of the timing chain (primary) with each sprocket, gradually turn the camshaft using a suitable tool on the hexagonal portion to align it with the mating marks.
    • During alignment, be careful to prevent dislocation of mating mark alignments of the secondary timing chains.

  13. Install the timing chain tensioner (primary) with the following procedure:
    1. Pull plunger stopper tab (A) up (or turn lever downward) so as to remove plunger stopper tab from the ratchet of plunger (D).
      GNSJPBIA0118Z-118Courtesy of NISSAN NORTH AMERICA, INC.
      NOTE: Plunger stopper tab and lever (C) are synchronized.
    2. Push plunger into the inside of tensioner body.
    3. Hold plunger in the fully compressed position by engaging plunger stopper tab with the tip of ratchet.
    4. To secure lever, insert stopper pin (E) through hole of lever into tensioner body hole (B).
      • The lever parts and the tab are synchronized. Therefore, the plunger will be secured under this condition.
      NOTE: Illustration shows the example of 1.2 mm (0.047 in) diameter thin screwdriver being used as the stopper pin.
    5. Install timing chain tensioner (primary) (1).
      GNSJPBIA0119Z-119Courtesy of NISSAN NORTH AMERICA, INC.
      • Remove any dirt and foreign materials completely from the back and the mount surfaces of timing chain tensioner (primary).
    6. Pull out stopper pin (A) after installing, and then release plunger.
  14. Reconfirm that the matching marks on the sprockets and the timing chain have not slipped out of alignment.
  15. Install the front timing chain case. Refer to Removal and Installation .
  16. Install the spark plugs. Refer to Exploded View .
  17. Install the intake manifold collector. Refer to Removal and Installation .
