Removal and Installation: Installation

• Apply new engine oil to both oil seal lip and dust seal lip.
• Install it so that each seal lip is oriented as shown.
  Fig 2: Identifying Oil And Dust Seal Lips

  
• Press-fit oil seal until it becomes flush with front timing chain case end face using suitable drift [outer diameter: 60 mm (2.36 in)].
• Make sure the garter spring is in position and seal lip is not inverted.
  CAUTION:

  • Be careful not to damage front timing chain case and crankshaft.
  • Press-fit straight and avoid causing burrs or tilting oil seal.
    Fig 3: Pressing Oil Seal

    

• Apply a continuous bead of liquid gasket using Tool to front timing chain case as shown.

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

2. Install new O-rings on rear timing chain case.
3. Assemble front timing chain case as follows:
   Fig 6: Identifying O-Rings Of Rear Timing Chain Case

   
   1. Fit lower end of front timing chain case tightly onto top face of oil pan (upper). From the fitting point, make entire front timing chain case contact rear timing chain case completely.
      Fig 7: Identifying Front Timing Chain Case, Cylinder Block And Oil Pan (Upper)

      
   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.
   3. Same as the previous step, insert dowel pin while holding front timing chain case from front and top completely.
      Fig 8: Holding Front Timing Chain Case

      
4. Tighten bolts to the specified torque in numerical order as shown.
5. After all bolts are tightened, retighten them to the specified torque in numerical order as shown.
   • There are two type of 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) 

Front oil pan bolt : 22.0 N.m (2.2 kg-m, 16 ft-lb)

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.

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

   Tool number : WS39930000 (-)

3. Install new collared O-rings in front timing chain case oil hole (left and right sides).
   Fig 12: Identifying O-Rings Of Front Timing Chain Case Oil Hole

   
4. Being careful not to move seal ring from the installation groove, align dowel pins on front timing chain case with the holes to install intake valve timing control covers.
5. Tighten bolts in numerical order as shown.

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 in two steps.

   Step 1 : 44.1 N.m (4.5 kg-m, 33 ft-lb) 

   Step 2 : 84° - 90° degrees clockwise 

3. Remove Tool to release the ring gear and install the rear cover plate. Refer to "EXPLODED VIEW ".
