NOTE

:
The oil strainer and oil pump are included in the oil pan (upper). Individual disassembly is prohibited.

REMOVAL

1. Remove the oil pan (lower). Refer to EM-169, "Exploded View".

3. Remove oil pan (upper) with the following procedure.

a. Loosen oil pan (upper) mounting bolts in the reverse of the order as shown in the figure.

: Engine front

b. Insert a flat-bladed offset screwdriver into the arrow (
) in the figure and open up a crack between the oil pan (upper) cylinder block.

: Engine front

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

CAUTION:
• Be careful not to damage the mating surface.

• A more adhesive liquid gasket is applied compared to previous types when shipped, so it should not be forced off using a screwdriver, etc. outside the indicated location.

• Never remove oil pump and oil strainer from oil pan (upper).

4. Remove rear oil seal from crankshaft.

INSTALLATION

1. Install the oil pan (upper) in the following procedure: a. Use scraper to remove old liquid gasket from mating surfaces.

• Also 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. Install O-ring to the cylinder block.

c. Apply a continuous bead of liquid gasket (C) with the tube presser (commercial service tool) to areas as shown in the figure.

Use Genuine Liquid Gasket or equivalent.

A : 2 mm (0.07 in) protruded to outside B : 2 mm (0.07 in) protruded to rear oil seal mounting side d : 5.5 - 7.5 mm (0.217 - 0.295 in) e : φ4.0 - 5.0 mm (0.157 - 0.197 in) : Engine front side
: Engine out side
A : Excess of 2 mm or more outward B : Excess of 2 mm or more in the rear oil seal mounting direction

CAUTION:
Attaching should be done within 5 minutes after coating.

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

: Engine front

CAUTION:
Install avoiding misalignment of both oil pan gasket and Oring.

• The bolts are different according to the installation position.

Refer to the numbers as shown in the figure.

M8×180 mm (7.09 in) : No. 9, 10 M8×25 mm (0.98 in) : No. 3, 4, 7, 8 M8×90 mm (3.54 in) : No. 1, 2, 5, 6

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).

• Never touch oil seal lip.

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

b. Apply the liquid gasket lightly to entire outside area of new rear oil seal.

Use Genuine Liquid Gasket or equivalent.

c. Press-fit the rear oil seal using a drift with outer diameter 113 mm (4.45 in) and inner diameter 90 mm (3.54 in) (commercial service tool) (A).

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

1 : Rear oil seal
A : Rear end surface of cylinder block b : 0 - 0.5 mm (0 - 0.020 in)

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 check that oil seal does not curl or tilt.

d. After press-fitting the rear oil seal, completely wipe off any liquid gasket protruding to rear end surface side.

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

Inspection

INSPECTION AFTER INSTALLATION

1. Check engine oil level and adjust engine oil. Refer to LU-25, "Inspection".

2. Check for leakage of engine oil when engine is warmed.
