NOTE:

• There is no positioning pawl.

• For service operation, the center position can be checked visually.

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

bearing (lower) (3) should be 0.85 mm or less when installing.

• Check that the oil hole in cylinder block and the oil hole (A) in

main bearing (1) are aligned.

4. Install the signal plate to the crankshaft according to the following procedure.
a. Set the signal plate with the flange facing toward the counterweight side (engine front side) to the crank-

shaft rear surface.

b. Lubricate threads and seat surface of each bolt with new engine oil.
c.

After positioning crankshaft (2) and signal plate (1) with position-

ing dowel pin (service parts), tighten bolts in the numerical order

shown in the figure.

NOTE:

• Dowel pin is included with crankshaft and signal plate respec-

tively.

• Use a TORX bit (size: T30) when installing the signal plate.

d. Tighten bolts again in the numerical order shown in the figure.
e. Remove dowel pin.

CAUTION:

Be sure to remove dowel pin.

5. Install the crankshaft to the cylinder block.

• Clean the journal to remove any foreign material, dust, and oil.

• Check that the crankshaft rotates smoothly by hand.

6. Install the main bearing cap.

• Install the main bearing cap, while referring to the front mark

(B) and the journal No. stamp (A).

NOTE:

Main bearing cap is machined together with cylinder block and

cannot be replaced by itself.

7. Tighten main bearing cap bolts in the numerical order shown in

the figure with the following steps.

CAUTION:

If the main bearing cap bolt is reused, check the outer diam-

eter in advance. Refer to 

EM-294, "Inspection"

.

• Use a TORX socket (size: E14).

a. Lubricate threads and seat surface of each bolt with new engine

oil.

b. Tighten the mounting bolts.

c. Tighten an additional 70

° (angle tightening).

• Use an angle wrench [SST: KV10112100 (BT8653-A)] (A) to

check tightening angle.

• If angle wrench is not available, put a matching mark on main

bearing cap bolts before turning them, and check turning angle

with a protractor.

CAUTION:

Check tightening angle using an angle wrench or a pro-

tractor. Never estimate tightening angle visually.

• After tightening main bearing cap bolts, rotate crankshaft by

hand and check that it turns smoothly.

• Check crankshaft side clearance. Refer to 

EM-294, "Inspec-

tion"

.

8. Install the piston to the connecting rod.
a. Use snap ring pliers (commercial service tool) to install snap ring in snap ring installation groove on rear

side of piston.

CAUTION:

Check that snap ring is securely seated in the groove.

b. Install the piston to the connecting rod.

• Using an industrial drier, heat piston to 60 – 70

°C so that piston pin can be easily inserted by hand.

Insert piston pin into piston and connecting rod from front side of piston.

• Assemble so that piston head front mark (A), connecting rod

oil hole (B), and connecting rod cylinder No. stamp (D) on are

positioned as shown in the figure.

NOTE:

• The symbol of connecting rod is one example.

• The symbols without notes are for management

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

CAUTION:

Check that snap ring is securely seated in the groove.

• Check that the connecting rod moves smoothly.

9. Install piston rings using a piston ring expander (commercial service tool).

CAUTION:

• Never damage piston.

• Be careful that the piston ring does not spread out too much and break.

• Position end gaps of each piston ring as shown in the figure.

CAUTION:

Never allow the rail end gap under the oil ring to contact

the oil drain cast groove of piston.

• Install top ring and second ring with stamp mark sides facing

up.

10. Install connecting rod bearing to connecting rod (1) and connect-

ing rod cap (4).

• Apply engine oil to the bearing surface (sliding surface). Do

not apply engine oil to the reverse side of the bearing, but thor-

oughly clean it.

• Install the connecting rod in the dimension as shown in the fig-

ure.

NOTE:

• There is no positioning pawl.

• When it is installed at the position as shown in the figure, the

connecting rod bearing is at the center. For service opera-

tion, the center position can be checked visually.

• Check that the bearing oil hole is in the inside of the connecting rod oil hole chamfered area completely.

• Temporarily install the connecting rod cap with the bearing to the connecting rod, and then check that

the connecting rod bearings (upper) and (lower) are in the correct positions.

11. Install the piston and connecting rod assembly to the crankshaft.

• Set crankshaft pin at the installation position to BDC on compression stroke.

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

• Match the cylinder position and the connecting rod cylinder

No. (D), and install.

• Install so that the front mark on the piston head faces engine

front.

vice tool) (A) so that front mark on piston head faces toward

engine front.

CAUTION:

• Never damage mating surface with connecting rod cap.

• The symbols without notes are for management purposes.

13. Tighten connecting rod bolts according to the following procedure.
