INSTALLATION SERVICE POINTS
 
 
>>A<< TIMING CHAIN CASE INSTALLATION
1.
cautionFollow the steps below to degrease the sealant application surface.
  • Before degreasing, make sure that the sealant application surface is free of dust, oil, or foreign materials.
  • Wipe the sealant application surface with a dry paper towel.
  • By using detergent for aluminum, degrease the sealant application surface by spray cleaning.
  • Wipe detergent thoroughly with a dry paper towel. Do not touch the sealant application surface with your fingers, as the fingerprints adhering to the sealant surface affect the sealing.
Completely remove sealant adhering to the timing chain case, cylinder block and cylinder head.
2. Degrease the surface where the sealant is applied and the contact surface between the cylinder block and the cylinder head.
3.
Apply sealant of 2.5 ± 0.5 mm(0.10 ± 0.02 inch) in thickness to the timing chain case. For the place "D" shown in the illustration, however, apply the sealant whose diameter is 4.5 ± 0.5 mm (0.18 ± 0.02 inch) or pile up the sealant of 2.5 ± 0.5 mm(0.10 ± 0.02 inch) as shown in the illustration.
Specified sealant: ThreeBond 1217G or equivalent
noteInstall the timing chain case assembly immediately after applying sealant.
4. The engine oil staying at the cylinder gasket oozes to the 3-plane contact surface described in Step 2 and 3. Swiftly apply the sealant to this area after degreasing.
Specified sealant: ThreeBond 1217G or equivalent
5.
cautionAfter the installation, until a sufficient period of time (one hour or more) elapses, do not apply the oil or water to the sealant application area or start the engine.
Tighten timing chain case mounting bolts to the specified torque.
Tightening torque
  • A: 24 ± 4 N·m (18 ± 2 ft-lb)
  • B: 10 ± 2 N·m (89 ± 17 in-lb)
  • C: 10 ± 2 N·m (89 ± 17 in-lb)
  • D: 12 ± 1 N·m (106 ± 8 in-lb)
 

 
 
>>B<< FRONT OIL SEAL INSTALLATION
1. Apply a small amount of engine oil to the entire inner diameter of the front oil seal lip.
2.
cautionThe front oil seal must not be a strong press fit. The strong press fit can possibly cause the oil leakage, damaging the front oil seal.
Use special tool MB991448 in order to press-fit the front oil seal into the timing chain case as shown in the illustration.
 

 
 
>>C<< OIL PAN INSTALLATION
1.
cautionFollow the steps below to degrease the sealant application surface.
  • Before degreasing, make sure that the sealant application surface is free of dust, oil, or foreign materials.
  • Wipe the sealant application surface with a dry paper towel.
  • By using detergent for aluminum, degrease the sealant application surface by spray cleaning.
  • Wipe detergent thoroughly with a dry paper towel. Do not touch the sealant application surface with your fingers, as the fingerprints adhering to the sealant surface affect the sealing.
Remove all the traces of sealant adhering to the oil pan and cylinder block assembly using a remover or others. Then, degrease them.
2. Apply sealant of Φ2.5 ± 0.5 mm (0.10 ± 0.02 inch) of thickness in diameter to the illustrated area of the oil pan.
Specified sealant: ThreeBond 1217G or equivalent
noteInstall the oil pan immediately after applying sealant.
3.
cautionAfter the installation, until a sufficient period of time (one hour or more) elapses, do not apply the oil or water to the sealant application area or start the engine.
Tighten the oil pan to the specified torque.
Tightening torque:
M6: 10 ± 2 N·m (89 ± 17 in-lb)
M8: 31 ± 2 N·m (23 ± 1 ft-lb)
 

 
 
>>D<< CYLINDER HEAD COVER INSTALLATION
1.
cautionFollow the steps below to degrease the sealant application surface.
  • Before degreasing, make sure that the sealant application surface is free of dust, oil, or foreign materials.
  • Wipe the sealant application surface with a dry paper towel.
  • By using detergent for aluminum, degrease the sealant application surface by spray cleaning.
  • Wipe detergent thoroughly with a dry paper towel. Do not touch the sealant application surface with your fingers, as the fingerprints adhering to the sealant surface affect the sealing.
Completely remove sealant adhering to the cylinder head cover, timing chain case and cylinder head.
2. Degrease the surface where the sealant is applied and the contact.
3. Appropriately use a minimum amount of sealant. Besides, be careful not to allow sealant to squeeze out from the application area.
Apply sealant of 4 mm (0.2 inch) of thickness in diameter.
Specified sealant: ThreeBond 1217G or equivalent
noteInstall the cylinder head cover immediately after applying sealant.
4. Tighten the cylinder head cover to the tightening torque in the order shown in the illustration.
Tightening torque: 3.0 ± 1.0 N·m (27 ± 8 in-lb)
5.
cautionAfter the installation, until a sufficient period of time (one hour or more) elapses, do not apply the oil or water to the sealant application area or start the engine.
Then, tighten it to the specified torque in the same order.
Tightening torque: 5.5 ± 0.5 N·m (49 ± 4 in-lb)
 

 
 
>>E<< OIL FILTER INSTALLATION
1. Clean the oil filter installing surface on the cylinder block side.
2. Apply a small amount of engine oil to the O-ring of the new oil filter.

3. Tighten the oil filter until the O-ring contacts with the installation surface.
4. In the same manner as removal, use special tool MB991396 or commercially-available tool to tighten the oil filter to the specified torque.
Tightening torque: Approximately one turn [14 ± 2 N·m (124 ± 17 in-lb)]
