Removal and Installation: Installation

WARNING: This page is about a different car, the 2006 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:
  • The above figure shows the relationship between the mating mark on each timing chain and that of the corresponding sprocket, with the components installed.
  • To install the timing chain and associated parts, start with those on the RH bank. The procedure for installing parts on the LH bank is omitted because it is the same as that for installation on the RH bank.
  1. Make sure the crankshaft key and RH bank camshaft dowel pin and LH bank camshaft dowel pin are facing in the direction shown.

  2. Install the camshaft sprockets.
    • Install the intake camshaft sprocket and exhaust camshaft sprockets by selectively using the groove of the dowel pin according to the bank. (Common part used for both banks.)
    • Lock the hexagonal part of the camshaft in the same way as for removal, and tighten the bolts.
    • A = I: Intake
    • B = E: Exhaust

  3. Install the crankshaft sprockets for both banks.
    • Install LH bank crankshaft sprocket (B) and RH bank crankshaft sprocket (C) so that their flange side (A) (the larger diameter side without teeth) faces in the direction shown.
      NOTE: The same parts are used but facing directions are different.

  4. Install the timing chains and associated parts.
    • Align the alignment mark on each sprocket and the timing chain for installation.
      CAUTION:
      • Before installing timing chain tensioner, it is possible to change the position of alignment mark on timing chain and each sprocket. After the alignment marks are aligned, keep them aligned by holding them by hand.
    • Install the slack guides and tension guides onto the correct side by checking the identification mark on the surface.
    • Install the timing chain tensioner with the plunger locked in with the stopper pin.
      CAUTION:
      • Before and after the installation of the timing chain tensioner, make sure that the alignment mark on the timing chain is not out of alignment.
      • After installing the timing chain tensioner, remove the stopper pin to release the tensioner. Make sure the tensioner is released.
      • To avoid chain-link skipping of the timing chain, do not move crankshaft or camshafts until the front cover is installed.
  5. In the same way as for the RH bank, install the timing chain and associated parts on the LH bank.
  6. Install the oil pump.
  7. Install the oil pump drive spacer as follows:
    • Install so that the front mark on the front edge of the oil pump drive spacer faces the front of the engine.
    • Insert the oil pump drive spacer according to the directions of the crankshaft key and the two flat surfaces of the oil pump inner rotor.

    • If the positional relationship does not allow the insertion, rotate the oil pump inner rotor to allow the oil pump drive spacer to be inserted.
  8. Install the front oil seal using suitable tool.
    CAUTION: Do not scratch or make burrs on the circumference of the oil seal.

  9. Install the chain tensioner cover.
    • Apply liquid gasket as shown.

      Use Genuine RTV Silicone Sealant or equivalent. Refer to  "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ".

  10. Install the front cover as follows:
    1. Install a new O-ring on the cylinder block.

    2. Apply liquid gasket as shown.

      Use Genuine RTV Silicone Sealant or equivalent. Refer to  "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ".

    3. Check again that the timing alignment marks on the timing chain and on each sprocket are aligned. Then install the front cover.
    4. Install the bolts in the numerical order shown.

      M6 x 50 mm (1.97 in): No. 1, 20, 25, 26, 27 

      M6 x 80 mm (3.15 in): No. 4, 5, 7 

      M6 x 20 mm (0.79 in): Except the above 

    5. After tightening, re-tighten to the specified torque.
      CAUTION: Be sure to wipe off any excessive liquid gasket leaking onto surface mating with oil pan.
  11. Install the timing chain case cover RH bank (A) and timing chain case cover LH bank (B) as follows:
    • *: Cross mark (c) that can not be seen after assembly

      D: 2.6 - 3.6 mm (0.102 - 0.142 in) dia.

    1. Apply liquid gasket (a) as shown.

      Use Genuine RTV Silicone Sealant or equivalent. Refer to  "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ".

      CAUTION: The start and end of the application of the liquid gasket should be crossed at a position that cannot be seen after attaching the chain case cover.
    2. Install the bolts in the numerical order shown.

  12. Install the crankshaft pulley.
    • Install the key of the crankshaft.
    • Insert the pulley by lightly tapping it.
      CAUTION: Do not tap pulley on the side surface where the belt is installed (outer circumference).
  13. Tighten the crankshaft pulley bolt.
    • Lock the crankshaft using suitable tool, then tighten the bolt.
    • Perform the following steps for angular tightening:
      1. Apply engine oil onto the threaded parts of the bolt and seating area.
      2. Select the one most visible notch of the four on the bolt flange.

        Corresponding to the selected notch, put a alignment mark (such as paint) on the crankshaft pulley.

        Crankshaft pulley bolt torque 

        Step 1: 93.1 N.m (9.5 kg-m, 69 ft-lb) 

        Step 2: additional 90° (angle tightening) 

  14. Rotate the crankshaft pulley in normal direction (clockwise when viewed from engine front) to check for parts interference.
  15. Installation of the remaining components is in the reverse of order of removal.
