Removal And Installation: Installation

WARNING: This page is about a different car, the 2004 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 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 slack guides and tension guides onto correct side by checking with identification mark on surface.
- Install chain tensioner with plunger locked in with stopper pin.
  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 the stopper pin to release tensioner. Make sure tensioner is released.
  - To avoid chain-link skipping of timing chain, never move crankshaft or camshafts until 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 oil pump drive spacer as follows:
- Install so that front mark on front edge of oil pump drive spacer faces the front of engine.
- 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 the oil pump drive spacer.

Using a suitable tool, install front oil seal.
CAUTION: Be careful not to scratch or make burrs on the circumference of the oil seal.

- Apply liquid gasket as shown in the figure. Use Genuine RTV Silicone Sealant or equivalent. Use Genuine RTV Silicone Sealant or equivalent. See RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS in GENERAL INFORMATION - TITAN article in GENERAL INFORMATION.
- Check again that the timing mating mark on timing chain and that on each sprocket are aligned. Then, install front cover.

- Install bolts in the numerical order shown in the figure.
- 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.
  1. M6 X 50 mm (1.97 in) :No. 1, 20, 25, 26, 27
  2. M6 X 80 mm (3.15 in) :No. 4, 5, 7
  3. M6 X 20 mm (0.79 in) :Except the above

Install chain case cover (right bank) and (left bank) as follows:
- Apply liquid gasket as shown in the figure. Use Genuine RTV Silicone Sealant or equivalent. See RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS in GENERAL INFORMATION - TITAN article in GENERAL INFORMATION.
  CAUTION: Both the start and end of application of liquid gasket should be crossed at an invisible position after attaching the chain case cover.

Install crankshaft pulley.
- Install key of crankshaft.
- Lightly tapping its center with plastic hammer, insert pulley.
  CAUTION: Do not tap pulley on the side surface where belt is installed (outer circumference).
Tighten crankshaft pulley bolt.
- Lock crankshaft with a hammer handle or similar tool to tighten bolt.
- Perform the following steps for angular tightening:
- Apply engine oil onto threaded parts of bolt and seating area.
- Select one most visible notch of the four on bolt flange. Corresponding to the selected notch, put a mating mark (such as paint) on crankshaft pulley.
  Crankshaft pulley bolt torque
  1. Step 1 : 93.1 N.m (9.5 kg-m, 69 ft-lb)
  2. 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.
