NOTE: This illustration shows the relationship between the mating mark on each timing chain and on the corresponding sprocket with the components installed.
  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)

    NOTE: Though camshaft does not stop at the position as shown above, for the placement of cam nose, it is generally accepted camshaft is placed in the same direction.

    : At cylinder head side of bank 1
  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 (orange link)] with the ones on camshaft sprockets [INT and EXH (punched)], and install them.
      • Mating marks for camshaft sprocket (INT) are on the back side of camshaft sprocket (secondary).
      • There are two types of mating mark, circle and oblong types. They should be used for the bank 1 and bank 2, respectively.

        Bank 1

        : Use circle type.

        Bank 2

        : Use oblong type.
      • Align dowel pin on camshafts with the groove or hole on sprockets, and install them.
      • On the intake side, align dowel pin on the camshaft front end with dowel pin hole on the back side of camshaft sprocket, and install them.
      • On the exhaust side, align dowel pin on camshaft front end with dowel 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 (A) on the top of sprocket teeth and its extended line in advance with paint.

  4. After confirming the mating marks are aligned, tighten the camshaft sprocket bolts using suitable tool (B).

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

  6. Install the crankshaft sprocket (C) on the crankshaft.

    • Make sure the mating marks (D) on the crankshaft sprocket (C) face the front of the engine (B).
    • The flat side of the crankshaft sprocket (C) is on the crankshaft side (A).
  7. Install the timing chain (primary).
    GNSAWBIA3388Z-388Courtesy of NISSAN NORTH AMERICA, INC.
    • Install timing chain (primary) so the mating mark [punched (B)] on camshaft sprocket (1) is aligned with the green link (A) on the timing chain, while the mating mark [notched (C)] on the crankshaft sprocket (2) is aligned with the orange 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 wrench 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.

    CAUTION: Do not over tighten slack guide mounting bolt (2). It is normal for a gap (A) to exist under the bolt seat when bolt is tightened to specification.

  9. 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 mounting surfaces of timing chain tensioner (primary).
    6. Pull out stopper pin (A) after installing, and then release plunger.
  10. Reconfirm that the matching marks on the sprockets and the timing chain have not slipped out of alignment.
  11. Install the spark plugs. Refer to Removal and Installation .
  12. Install the intake manifold collector. Refer to Removal and Installation .
  13. Install the front timing chain case. Refer to Removal and Installation .
