Removal and Installation: Installation

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

Hammer dowel pins (right and left) into front timing chain case up to a point close to taper in order to shorten protrusion length.

Install new front oil seal on the front timing chain case.
- Apply new engine oil to both oil seal lip and dust seal lip.
- Install it so that each seal lip is oriented as shown below.

Install water pump cover and chain tensioner cover to front timing chain case, if removed.
- Apply a continuous bead of liquid gasket using Tool to front timing chain case as shown below.
  Tool number: WS39930000 (-)
  
  Use Genuine RTV Silicone Sealant or equivalent. Refer to "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ".

  2. Since front timing chain case is offset for difference of bolt holes, tighten bolts temporarily while holding front timing chain case from front and top as shown below.
  3. Same as the previous step, insert dowel pin while holding front timing chain case from front and top completely.

4. Tighten bolts to the specified torque in numerical order as shown below.
  - There are four type of bolts. Refer to the following for locating bolts.
    Bolt position Bolt diameter
    
    1 - 5: 10 mm (0.39 in)
    
    6 - 25: 6 mm (0.24 in)
    
    Bolt position Tightening specification
    
    1 - 5: 55.0 N.m (5.6 kg-m, 41 ft-lb)
    
    6 - 25: 12.7 N.m (1.3 kg-m, 9 ft-lb)

5. After all bolts tightened, retighten them to the specified torque in numerical order as shown below.
Install two bolts in front of oil pan (upper) in numerical order as shown below.
Front oil pan bolt torque: 22.0 N.m (2.2 kg-m, 16 ft-lb)

Install right and left intake valve timing control covers as follows:
1. Install new seal rings in shaft grooves.
2. Apply a continuous bead of liquid gasket using Tool to intake valve timing control covers as shown below.
  Tool number: WS39930000 (-)
  
  Use Genuine RTV Silicone Sealant or equivalent. Refer to "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ".

Install crankshaft pulley as follows:
1. Install crankshaft pulley, taking care not to damage front oil seal.
  - When press-fitting crankshaft pulley with plastic hammer, tap on its center portion (not circumference).
2. Tighten crankshaft pulley bolt.
  Crankshaft bolt torque: 44.1 N.m (4.5 kg-m, 33 ft-lb)
3. Put a paint mark on crankshaft pulley aligning with angle mark on crankshaft pulley bolt. Then, further retighten bolt by 60 degrees (equivalent to one graduation).

Rotate crankshaft pulley in normal direction (clockwise when viewed from front) to confirm it turns smoothly.
Installation of the remaining components is in the reverse order of removal after this step.
