Oil Pan and Timing Chain Case

OIL PAN AND TIMING CHAIN CASE

REMOVAL AND INSTALLATION

Removal Steps 1-16:

REMOVAL SERVICE POINTS

[[A]] OIL FILTER REMOVAL





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

CAUTION
^ Be sure to remove the liquid gasket entering the mounting holes, the O-ring grooves and the cylinder gasket clearance.
^ Sufficiently check whether there is no residual oil on the place where degreasing is performed using white gasoline, such as the surface where the FIPG is applied and stays, or the chamfered area.
^ Do not touch the area where degreasing must be performed since the oils from your fingers will harm the seal ability.

1. Use white gasoline to 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. Using white gasoline, carry out the degreasing





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

3. Apply liquid gasket (Three bond 1217G or 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 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. Using white gasoline and so on, degrease the cylinder block and oil pan.

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





3. Apply liquid gasket (Three bond 1217G or equivalent) of [diameter]2.5±0.5 mm (0.10±0.02 inch) of thickness in diameter to the illustrated area of the oil pan.
4. Tighten the oil pan to the specified torque.
Specified torque
M6: 10±1 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. Using white gasoline and so on, 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 (Three bond 1217G or equivalent) of 4 mm of thickness in diameter.





4. Tighten the cylinder head cover to the tightening torque of 3.0±1.0 Nm (27±8 in-lb) in the order shown in the illustration.
5. Then, tighten it to the specified torque in the same order.
Specified 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]).
