REMOVAL SERVICE POINTS

[[A]] OIL FILTER REMOVAL





1. Use special tool MB991396 to remove the oil filter.

[[B]] OIL PAN REMOVAL

1. Remove oil pan tightening bolts.

CAUTION:
Lightly tap the oil pan FIPG cutter to drive in, taking care not to damage the ladder frame and oil pan sealed area.





2. Lightly tap special tool MD998727 to drive in the illustrated groove of the oil pan and ladder frame.





3. Lightly tap and slide special tool 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 the liquid gasket adhering to the timing chain case, the cylinder block and the cylinder head.

2. Completely remove the sealant remaining on the 3-plane contact surface among the cylinder head, the cylinder block and the gasket.Carry out the digressing

3.





CAUTION:
Install the timing chain case within three minutes after applying the liquid gasket.

Apply liquid gasket (Three bond 1217G or exact equivalent) of 2.5 ± 0.5 mm (0.10 ± 0.02 inch) in thickness to the timing chain case. For illustrated A locations, however, apply liquid gasket of 4.5 ± 0.5 mm (0.18 ± 0.02 inch) in diameter or liquid gasket of 2.5 ± 0.5 mm (0.10 ± 0.02 inch) by putting one on top of another as shown in the illustration.





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:

Three bond 1217G or exact equivalent






5. Tighten timing chain case mounting bolts to the specified tightening torque.
Tightening torque

A: 24 ± 4 Nm (18 ± 2 ft-lb)
B: 10 ± 2 Nm (89 ± 17 in-lb)
C: 10 ± 2 Nm (89 ± 17 in-lb)
D: 13 ± 1 Nm (115 ± 8 in-lb)


]]B[[ FRONT OIL SEAL INSTALLATION

1. Apply engine oil to the internal circumference of the oil seal.





2. Use special tool MB991448 to install the front oil seal on the timing chain case.

]]C[[ OIL PAN INSTALLATION

1. Completely remove liquid gasket adhering to the cylinder block and oil pan.

2. Degrease the cylinder block and oil pan.

CAUTION:
Install the oil pan within three minutes after liquid gasket is applied.





3. Apply liquid gasket of dia.2.5 ± 0.5 mm (0.10 ± 0.02 inch) of thickness in diameter to the illustrated area of the oil pan.
Specified sealant:

Three bond 1217G or exact equivalent
4. Tighten the oil pan to the specified tightening torque.
Tightening torque:
M6:10 ± 2 Nm (89 ± 17 in-lb)
M8: 29 ± 2 Nm (21 ± 1 ft-lb)


]]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 cylinder head cover, timing chain case and cylinder head.

CAUTION:
Install the cylinder head cover immediately after liquid gasket is applied.





3. Appropriately use a minimum amount of sealant. Be careful not to allow sealant to squeeze out from the application area.
Apply liquid gasket of 4 mm (0.15 inch) of thickness in diameter.
Specified sealant:

Three bond 1217G or exact equivalent






4. 5. Tighten the cylinder head cover to the tightening torque in the order shown in the illustration.
Tightening torque: 3.0 ± 1.0 Nm (27 ± 8 in-lb)
6. Then, tighten it to the specified tightening torque in the same order.
Tightening torque: 5.5 ± 0.5 Nm (49 ± 4 in-lb)


]]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 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
Specified torque: 3/4 turn (14 ± 2 Nm [124 ± 17 in-lb]).
