Removal and Installation

REMOVAL

1. Remove oil pan (lower). Refer to EM-99, "Exploded View".

2. Remove oil filter. Refer to LU-11, "Removal and Installation".

3. Remove front cover, timing chain, oil pump drive chain, and other related parts. Refer to EM-67, "Exploded View".

4. Remove oil level gauge and oil level gauge guide.

5. Remove oil pump. Refer to LU-15, "Exploded View".

NOTE

:
The oil pan (upper) can be removed and installed without removing the oil pump.

6. Remove oil pan (upper) with the following procedure: a. Loosen bolts in reverse order as shown in the figure.

: Engine front

b. Insert a screwdriver shown by the arrow ( ) in the figure and open up a crack between oil pan (upper) and cylinder block.

: Engine front

CAUTION:
A more adhesive liquid gasket is applied compared to previous types when shipped, so it should not be forced off the position not specified.

c. Insert seal cutter [SST: KV10111100 (J-37228)] between oil pan (upper) and cylinder block, and slide it by tapping on the side of the tool with a hammer.

CAUTION:
Be careful not to damage the mating surface.

7. Remove O-ring between cylinder block and oil pan (upper).

INSTALLATION

1. Install oil pan (upper) with the following procedure:

A. Use a scraper (a) to remove old liquid gasket from mating surfaces.

• Remove the old liquid gasket from mating surface of cylinder block.

• Remove old liquid gasket from the bolt holes and threads.

Caution:
never scratch or damage the mating surfaces when cleaning off old liquid gasket.

B. Apply a continuous bead of liquid gasket (d) with a tube presser (commercial service tool) as shown in the figure.

1 : Oil pan (upper)
a : 2 mm (0.08 In) protruded to outside b : 2 mm (0.08 In) protruded to rear oil seal mounting side c : 5.5 - 7.5 Mm (0.217 - 0.295 In) e : 4.0 - 5.0 Mm (0.157 - 0.197 In) : engine front
: engine outside

Use genuine liquid gasket or equivalent.

• Attaching should be done within 5 minutes after liquid gasket application.

c. Install new O-ring at cylinder block side.

CAUTION:C. Install new o-ring at cylinder block side.

Install avoiding misalignment of O-ring.

d. Tighten bolts in numerical order as shown in the figure.

: Engine front

2. Install rear oil seal with the following procedure.

Caution:
• the installation of rear oil seal should be completed within 5 minutes after installing oil pan (upper).

• Always replace rear oil seal with new one.

• Never touch oil seal lip.

A. Wipe off liquid gasket protruding to the rear oil seal mounting part of oil pan (upper) and cylinder block using a scraper.

B. Apply engine oil to entire outside area of rear oil seal.

C. Press-fit the rear oil seal using a suitable drift (a) with outer diameter 115 mm (4.53 In) and inner diameter 90 mm (3.54 In).

• Press-fit to the specified dimensions as shown in the figure.

1 : Rear oil seal
A : Cylinder block rear end surface

CAUTION:
• Never touch the grease applied to the oil seal lip.

• Be careful not to damage the rear oil seal mounting part of oil pan (upper) and cylinder block or the crankshaft.

• Press-fit straight, checking that rear oil seal does not curl or tilt.

NOTE:

The standard surface of the dimension is the rear end surface of cylinder block.

3. Install in the reverse order of removal, for the rest of parts.
