3. Install main bearings and thrust bearings with the following procedure:
a. Remove dust, dirt, and engine oil on the bearing mating surfaces of cylinder block and main bearing cap.
b. Install thrust bearings to the both sides of the No. 3 journal hous-

ing (B) on cylinder block.

• Install thrust bearings with the oil groove (A) facing crankshaft

arm (outside). 

c.

Install the main bearings paying attention to the direction.

• Before installing main bearings, apply new engine oil to the bearing surface (inside). Do not apply new

engine oil to the back surface, but thoroughly clean it.

• When installing, align main bearing to the center position of cylinder block and main bearing cap.

• The difference (A) between main bearing (upper) (1) and main

bearing (lower) (3) should be 0.85 mm (0.0335 in) or less

when installing.

• Ensure the oil holes on cylinder block and oil holes (A) on the

main bearings (1) are aligned.

4. Install signal plate to crankshaft if removed.
a. Set the signal plate with the flange facing toward the counter weight side (engine front side) to the crank-

shaft rear surface.

b. Apply new engine oil to threads and seat surfaces of mounting bolts.

c. Position crankshaft (2) and signal plate (1) using a dowel pin

(service part), and tighten mounting bolts in numerical order as

shown in the figure using TORX socket.

NOTE:

Dowel pin of crankshaft and signal plate is provided as a set for

each.

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

again.

e. Remove dowel pin. (service parts)

CAUTION:

Be sure to remove dowel pin.

5. Install crankshaft to cylinder block.

• While turning crankshaft by hand, check that it turns smoothly. 

6. Install main bearing caps with the following procedure:
a. Install main bearing caps referring to the journal No. stamp (A)

and front mark (B) as shown in the figure. 

NOTE:

Main bearing cap cannot be replaced as a single part, because it

is machined together with cylinder block.

b. Tighten main bearing cap bolts in numerical order as shown in

the figure with the following procedure:

i.

Apply new engine oil to threads and seat surfaces of mounting

bolts.

ii.

Tighten main bearing cap bolts.

iii. Turn main bearing cap bolts 70 degrees clockwise (angle tightening) in order from No. 1 to 10 in the fig-

ure.

CAUTION:

Confirm the tightening angle by using an angle wrench

[SST: KV10112100 (BT8653-A)] (A) or protractor. Never

judge by visual inspection without the tool. 

• After installing mounting bolts, check that crankshaft can be rotated smoothly by hand.

• Check crankshaft end play. Refer to 

EM-123, "Inspection"

.

7. Install piston to connecting rod with the following procedure:

a. Using snap ring pliers, install new snap ring to the groove of the piston rear side. 

• Insert it fully into groove to install. 

b. Assemble piston to connecting rod.

• Using an industrial use drier or similar tool, heat the piston until the piston pin can be pushed in by hand

without excess force [approximately 60 to 70

°C (140 to 158°F)]. From the front to the rear, insert piston

pin into piston and connecting rod.

• Assemble so that the front mark (A) on the piston head and

the oil hole (B) and the cylinder number (D) on connecting rod

are positioned as shown in the figure.

c.

Install new snap ring to the groove of the piston front side. 

• Insert it fully into groove to install. 

• After installing, check that connecting rod moves smoothly.

8. Using a piston ring expander (commercial service tool), install

piston rings. 

CAUTION:

• Never damage piston.

• Never damage piston rings by expanding them excessively.

• Position each ring with the gap as shown in the figure referring

to the piston front mark.

CAUTION:

Never contact the rail end gap under the oil ring with the

oil drain cast groove of piston.

• Install second ring with the stamped surface facing upward.

9. Install connecting rod bearing upper (2) and lower (3) to con-

necting rod (1) and connecting rod cap (4).

• Install the connecting rod in the dimension shown in the figure. 

• Check that connecting rod bearing oil hole (A) is completely in

the inside of connecting rod oil hole chamfered area (B).

• When installing connecting rod bearings, apply new engine oil

to the bearing surface (inside). Do not apply new engine oil to

the back surface, but thoroughly clean it. 

NOTE:

• There is no positioning tab.

• Install the connecting rod bearings in the center of connect-

ing rod and connecting rod cap as shown in the figure. For

service operation, the center position can be checked, visu-

ally.

10. Install piston and connecting rod assembly to crankshaft. 

• Position crankshaft pin corresponding to connecting rod to be installed onto the bottom dead center. 

• Apply new engine oil sufficiently to the cylinder bore, piston and crankshaft pin. 

• Match the cylinder position with the cylinder number (D) on

connecting rod to install. 

• Install so that front mark (A) on the piston head faces the front

of engine.

• Using a piston ring compressor [SST: EM03470000 (J-8037)]

(A) or suitable tool, install piston with the front mark on the pis-

ton head facing the front of the engine. 

CAUTION:

Be careful not to damage the cylinder wall and crankshaft

pin, resulting from an interference of the connecting rod

big end.

11. Install connecting rod cap. 

• Match the stamped cylinder number marks (D) on connecting

rod with those on connecting rod cap to install.   

12. Tighten connecting rod cap bolt with the following procedure:

CAUTION:

• Check that there is no gap in the thrust surface (A) of the

joint between connecting rod (1) and connecting rod cap

(2) and that these parts are in the correct position. And

then, tighten the connecting rod cap bolts.

• If the connecting rod cap bolts are reused, measure the

outer diameter. Refer to 

EM-123, "Inspection"

.

a. Apply new engine oil to the threads and seats of connecting rod

cap bolts. 

b. Tighten connecting rod cap bolts.
