a. Loosen and remove bolts in several steps in the reverse order of

the numerical order shown in the figure.

• Measure crankshaft side clearance before loosening main

bearing cap bolts.  Refer to 

EM-294, "Inspection"

.

• Use a TORX socket (size: E14).

• Never place crankshaft onto the floor or another flat sur-

face. Use a block of wood for maintaining a clearance and

preventing signal plate from interfering with the floor.

• Never remove the signal plate unless necessary.

NOTE:

Use a TORX bit (size: T30) for removal of the signal plate.

11. Pull the rear oil seal out from the rear end of crankshaft.
12. Remove the main bearings and the thrust bearings from the cyl-

inder block and the main bearing caps.

CAUTION:

Check the installation position of each part. Store the removed parts to prevent them from being

mixed up.

ASSEMBLY

1. Thoroughly clean engine coolant and oil passages in cylinder block, as well as inside of crankcase and

cylinder bores, with compressed air.

CAUTION:

Be sure to wear protective goggles for protection from flying substances.

2. Refer to the figure and install each plug into the cylinder block.

3. Install main bearing and thrust bearing according to the following procedure.
a. Clean bearing mounting surfaces on cylinder block and main bearing cap to remove any foreign material,

dust, and oil.

b. Install thrust bearings on both sides (B) of cylinder block No. 3

housing.

• Install thrust bearing with its oil groove (A) facing crankshaft

arm side (outer side).

c. Install the main bearing.

• Before installing bearing, lubricate bearing surface (inside) with new engine oil.

• Do not apply engine oil to reverse side of main bearing, but thoroughly clean it.

• Install main bearing to the center position between cylinder block and main bearing cap.
