Rear Timing Chain Case: Assembly

WARNING: This page is about a different car, the 2008 Infiniti EX35. However, it is still accessible from the selected car via links, so may be relevant.

Install timing chain tensioners (secondary) to cylinder head as follows if removed. Refer to EXPLODED VIEW .
1. Install timing chain tensioners (secondary) with a stopper pin attached and new O-rings.
2. Install camshaft brackets (No. 1). Refer to EXPLODED VIEW .
3. Measure difference in levels between front end faces of camshaft bracket (No. 1) and cylinder head.
  Standard: -0.14 to 0.14 mm (-0.0055 to 0.0055 in)
  - Measure two positions (both intake and exhaust side) for a single bank.
  - If the measured value is out of the standard, re-install camshaft bracket (No. 1).

2. Apply liquid gasket with the tube presser (commercial service tool) to rear timing chain case back side as shown in the figure.
  Use Genuine RTV Silicone Sealant or equivalent. Refer to RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS .
  CAUTION:
  - For (A) in the figure, completely wipe out liquid gasket extended on a portion touching at engine coolant.
  - Apply liquid gasket on installation position of water pump and cylinder head very completely.

3. Align rear timing chain case with dowel pins (bank 1 and bank 2) on cylinder block and install rear timing chain case.
  - Check O-rings stay in place during installation to cylinder block and cylinder head.
4. Tighten mounting bolts in numerical order as shown in the figure.
  - There are two types of mounting bolts. Refer to the following for locating bolts.
    Bolt length: Bolt position
    
    20 mm (0.79 in): 1, 2, 3, 6, 7, 8, 9, 10
    
    16 mm (0.63 in): 4, 5, 11, 12, 13
    
    Specified Torque: 12.7 N.m (1.3 kg-m, 9 ft-lb)

    Bolt length: Bolt position
    
    16 mm (0.63 in): Except the above
    
    Specified Torque: 15.0 N.m (1.5 kg-m, 11 ft-lb)
5. After all bolts are tightened, retighten them to the specified torque in numerical order shown in the figure.
  - If liquid gasket protrudes, wipe it off immediately.
6. After installing rear timing chain case, check the surface height difference between the following parts on the oil pan (upper) mounting surface.

  Standard
  
  Rear timing chain case to lower cylinder block:
  
  -0.24 to 0.14 mm (-0.0094 to 0.0055 in)
  - If not within the standard, repeat the installation procedure.
Install water pump with new O-rings. Refer to EXPLODED VIEW .
Check that dowel pin (A) and crankshaft key (1) 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.

Camshaft dowel pin

: At cylinder head upper face side in each bank.

Crankshaft key

: At cylinder head side of bank 1.

Install timing chains (secondary) and camshaft sprockets as follows:
CAUTION: Matching marks between timing chain and sprockets slip easily. Confirm all matching mark positions repeatedly during the installation process.
1. Push plunger of timing chain tensioner (secondary) and keep it pressed in with a stopper pin (A).
