Removal and Installation: Installation

WARNING: This page is about a different car, the 2005 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 timing chain and associated 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.

Make sure the crankshaft key and dowel pin of each camshaft are facing in the direction as shown.

Install camshaft sprockets.
- Install intake and exhaust camshaft sprocket 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 way as for removal, and tighten bolts.

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 as shown.
  NOTE: The same parts are used but facing directions are different.

Install the timing chains and associated parts.
- Align the mating mark on each sprocket and the timing chain for installation.
  CAUTION:
  - Before installing chain tensioner, it is possible to change the position of mating mark on timing chain and each sprocket. After the mating 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 chain tensioner with the plunger locked in with the stopper pin.
  CAUTION:
  - Before and after the installation of the chain tensioner, make sure that the mating mark on the timing chain is not out of alignment.
  - After installing the 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.
In the same way as for right bank, install timing chain and associated parts on left side.
Install oil pump.
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.

Install the front oil seal using suitable tool.
CAUTION: Do not scratch or make burrs on the circumference of the oil seal.

Install chain tensioner cover.
- Apply liquid gasket as shown.
  Use Genuine RTV Silicone Sealant or equivalent. Refer to " RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS " .

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 mating mark on timing chain and that on each sprocket are aligned. Then install front cover.
4. Install bolts in the numerical order shown.
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.
  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
Install chain case cover (right bank and left bank) as follows:
1. Apply liquid gasket 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.

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).
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 mating 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)

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