Removal And Installation: Installation

WARNING: This page is about a different car, the 2004 Infiniti FX45 and 2003 Infiniti FX45. 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 on the corresponding sprocket, with the components installed.
  • Parts with an identification mark (R or L) should be installed on the corresponding bank according to the mark.

Parts with an identification mark:

  • Camshaft sprocket (INT)
  • Dowel pin groove of camshaft sprocket (EXH) (camshaft sprocket is same part both banks)
  • Chain tension guide
  • Chain slack guide
  • Because of parallel manufacture, there are two types of mark (link colors) for timing chain.
  • To install timing chain and related parts, start with those on right bank. The procedure for installing parts on left bank is omitted because it is the same as that for installation on right bank.
  1. Make sure that crankshaft key and dowel pin of each camshaft are located as shown in the figure. (No. 1 cylinder at compression TDC)
    NOTE: Though camshaft does not stop at the position as shown in the figure, for the placement of cam nose, it is generally accepted camshaft is placed for the same direction of the figure.

    1. Camshaft dowel pin: 
      1. At cylinder head upper face side in each bank 
    2. Crankshaft key: 
      1. At cylinder head side of left bank 
  2. Install camshaft sprockets.
    • Install onto correct side by checking with identification mark on surface.
    • Install camshaft sprocket (EXH) by selectively using the groove of dowel pin according to the bank. (Common part used for both banks.)
    • Lock the hexagonal part of camshaft in the same procedure as for removal, and tighten mounting bolts.

  3. Install crankshaft sprockets for both banks.
    • Install each crankshaft sprocket so that its flange side (the larger diameter side without teeth) faces in the direction shown in the figure.

    NOTE: The same parts are used but facing directions are different.
  4. Install timing chains and related parts.

    • Align the mating mark on each sprocket and timing chain for installation.
      CAUTION: For the above reason, after the mating marks are aligned, keep them aligned by holding them with a hand.
      NOTE: Before installing chain tensioner, it is possible to change the position of mating mark on timing chain for that on each sprocket for alignment.
    • Install slack guides and tension guides onto correct side by checking with identification mark on surface.
    • Install chain tensioner with plunger fixed as described in its removal.
    CAUTION:
    • Before and after the installation of chain tensioner, make sure that the mating mark on timing chain is not out of alignment.
    • After installing chain tensioner, remove stopper pin to release tensioner. Make sure tensioner is released.
    • To avoid chain-link skipping of timing chain, do not move crankshaft or camshafts until front cover is installed.
  5. Perform the same procedure as for right bank, install timing chain and related parts on left side.
  6. Install oil pump. Refer to OIL PUMP .
  7. Install oil pump drive spacer as follows:
    Fig 6: Installing Oil Pump Drive Spacer

    1. Insert oil pump drive spacer according to the directions of crankshaft key and the two flat surfaces of oil pump inner rotor.
      • If the positional relationship does not allow the insertion, rotate oil pump inner rotor with a finger to allow spacer.
    2. After confirming that the position of each part is in correct condition to allow for spacer, force fit spacer by lightly tapping with plastic hammer until it contacts and does not go further.
  8. Install front oil seal on front cover.
    • Apply new engine oil to both oil seal lip and dust seal lip.
    • Install it so that each seal lip is oriented as shown in the figure.

      CAUTION: Be careful not to scratch or make burrs on circumference of oil seal.
    • Using suitable drift, press fit until the height of front oil seal is level with the mounting surface.

      Suitable drift 

      1. Outer diameter : 56 mm (2.20 in) 
      2. Inner diameter : 49 mm (1.93 in) 

    • Make sure the garter spring is in position and seal lips not inverted.

  9. Install chain tensioner cover to front cover.
    • Apply a continuous bead of liquid gasket with tube presser [SST: WS39930000 ( - )] to front cover as shown in the figure.

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

  10. Install front cover as follows:
    1. Install new O-rings onto cylinder heads (right and left bank) and cylinder block.

      CAUTION: Be sure to wipe off any excessive liquid gasket leaking onto surface mating with oil pan.
  11. Install intake valve timing control cover as follows:
    1. At the back of intake valve timing control cover, install new seal rings (three for each bank) to the area to be inserted into camshaft sprocket (INT).
      CAUTION: Do not spread seal ring excessively to avoid breaks and deformation.
    2. Install new O-rings on front cover.

  12. Install intake valve timing control position sensor, intake valve timing control solenoid valve and camshaft position sensor (PHASE) to intake valve timing control cover and front cover if removed.
    • Be sure to tighten bolts with flanges completely seated.
  13. Install oil pan and oil strainer. Refer to OIL PAN AND OIL STRAINER .
  14. Install crankshaft pulley as follows:
    1. Fix crankshaft with ring gear stopper [SST: J-45476].
    2. Install crankshaft pulley, taking care not to damage front oil seal.
      • Install according to dowel pin of oil pump drive spacer.
      • Lightly tapping its center with plastic hammer, insert pulley.
        CAUTION: Do not tap pulley on the side surface where belt is installed (outer circumference).
    3. Apply engine oil onto threaded parts of crankshaft pulley bolt and seating area.
    4. Tighten crankshaft pulley bolt.
      1. 93.1 N.m (9.5 kg-m, 69 ft-lb) 
    5. Put a paint mark on crankshaft pulley aligning with angle mark on crankshaft pulley bolt.
    6. Further tighten by 90 degrees. (Angle tightening)
      • Check the tightening angle by referencing the notches. The angle between two notches is 90 degrees.

  15. Rotate crankshaft pulley in normal direction (clockwise when viewed from engine front) to confirm it turns smoothly.
  16. Install in the reverse order of removal after this step.
    NOTE: If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may generate a pounding noise during and just after engine start. However, this does not indicate an unusualness. Noise will stop after hydraulic pressure rises.
