REMOVAL SERVICE POINTS



<<A>> OIL FILTER REMOVAL



1.Use special tool Oil filter wrench (MB991396) to remove the oil filter.

<<B>> OIL PAN REMOVAL


1.Remove oil pan tightening bolts.

2.
caution Lightly tap the oil pan FIPG cutter to drive in, taking care not to damage the ladder frame and oil pan sealed area.
Lightly tap special tool Oil pan FIPG cutter (MD998727) to drive in the illustrated groove of the oil pan and ladder frame.

3.Lightly tap and slide special tool Oil pan FIPG cutter (MD998727) to remove the oil pan.

<<C>> TIMING CHAIN CASE REMOVAL



If the timing chain case is difficult to remove, insert a hammer handle as shown in the illustration and lightly pry it.

INSTALLATION SERVICE POINTS



>>A<< TIMING CHAIN CASE INSTALLATION


1.
caution
  • Completely remove all the old liquid gasket, which might be remaining in the installation hole, the O-ring groove or among the components such as the cylinder head gasket.
  • Sufficiently check that there is no residual oil on the place where degreasing is performed. If fingerprints are left, do not touch it with bare hands after the degreasing, since the oils from your fingers will harm the seal ability.
Completely remove liquid gasket adhering to the timing chain case, cylinder block and cylinder head.
2.Degrease the surface where the liquid gasket is applied and the contact surface between the cylinder block and the cylinder head.
3.

caution Install the timing chain case within three minutes after applying the liquid gasket.
Apply liquid gasket of 2.5 ± 0.5 mm in thickness to the timing chain case. For the place "D" shown in the illustration, however, apply the liquid gasket whose diameter is 4.5 ± 0.5 mm or pile up the liquid gasket of 2.5 ± 0.5 mm as shown in the illustration.
Specified sealant:
    ThreeBond 1217G or equivalent

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 liquid gasket to this area after degreasing.
Specified sealant:
    ThreeBond 1217G or equivalent

5.Tighten timing chain case mounting bolts to the specified torque.
Tightening torque
    A: 24 ± 4 N·m
    B: 10 ± 2 N·m
    C: 10 ± 2 N·m
    D: 13 ± 1 N·m

>>B<< FRONT OIL SEAL INSTALLATION


1.Apply a small amount of engine oil to the entire inner diameter of the front oil seal lip.

caution The 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.
2.Use special tool Bush remover and installer base (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.Completely remove liquid gasket adhering to the cylinder block and oil pan.

caution Install the oil pan within three minutes after liquid gasket is applied.
2.Apply liquid gasket of Φ2.5 ± 0.5 mm of thickness in diameter to the illustrated area of the oil pan.
Specified sealant:
    ThreeBond 1217G or equivalent
3.Tighten the oil pan to the specified torque of 10 ± 2 N·m (M6) and 29 ± 2 N·m (M8).

>>D<< CYLINDER HEAD COVER INSTALLATION


1.Completely remove liquid gasket adhering to the cylinder head cover, timing chain case and cylinder head.
2.Degrease the surface where the liquid gasket is applied and the contact.

caution Install the cylinder head cover immediately after liquid gasket is applied.
3.Appropriately use a minimum amount of sealant. Besides, be careful not to allow sealant to squeeze out from the application area.
Apply liquid gasket of 4 mm of thickness in diameter.
Specified sealant:
    ThreeBond 1217G or equivalent

4.5.Tighten the cylinder head cover to the tightening torque of 3.0 ± 1.0 N·m in the order shown in the illustration.
6.Then, tighten it to the specified torque of 5.5 ± 0.5 N·m in the same order.

>>E<< OIL FILTER INSTALLATION


1.Clean the oil filter mounting surface of the ladder frame.

2.Apply engine oil to the O-ring of the oil filter.

caution Use special tool Filter wrench (MB991396) to install the oil filter. Tightening it by hand causes oil leakage due to lack of torque.
3.Screw in the oil filter. When the O-ring contacts the mounting surface, use a filter wrench to tighten it 1 turns (14 ± 2 N·m).
