3. Install oil jets.
4. Install main bearings and thrust bearings:
a. Remove dust, dirt, and engine oil on the bearing mating surfaces of cylinder block.
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

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.

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

main bearings (1) are aligned.

NOTE:

For assembly, the center position can be visually identified.

• To install the main bearing, obtain a proper fit. Do not allow the

main bearing to lie off the cylinder block chamfer.

• To install the main bearing, obtain a proper fit. Do not allow the

main bearing to lie off bearing cap chamfer.

5. Install signal plate to crankshaft if removed.
a. Set the signal plate (1) with the flange facing toward the counter-

weight side (engine front side) to the crankshaft rear surface.

b. After positioning crankshaft and signal plate with positioning

dowel pin, tighten bolt.

NOTE:

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

each.

c.

Remove dowel pin.

CAUTION:

Be sure to remove dowel pin.

6. Install crankshaft to cylinder block.

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

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

(B) and the journal number stamp (A).

NOTE:

Main bearing cap cannot be replaced as a single part,

because it is machined together with cylinder block.

8. Tighten main bearing cap bolts in numerical order as shown with

the following steps:

a. Apply new engine oil to threads and seat surfaces of the bolts.
b. Tighten main bearing cap bolts in numerical order.

c. Turn main bearing cap bolts 60 degrees clockwise (angle tight-

ening) in numerical order as shown.

CAUTION:

Check and confirm the tightening angle by using the Tool

(A) or protractor. Do not judge by visual inspection without

the tool. 

• After installing the main bearing cap bolts, check that crankshaft can be rotated smoothly by hand.

• Check crankshaft end play. Refer to 

EM-101, "Inspection"

.

9. Install piston to connecting rod with the following procedure: 
a. Using a heat gun, 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 con-

necting rod.

b. Set so that the front mark (A) on the piston head and the cylin-

der number (C) are in the position as shown.

NOTE:

The symbols without notes are for manufacturing.

CAUTION:

Press-fit the piston so as not to damage it.

NOTE:

The joint between the connecting rod and the piston pin is a

press fit.

• Press-fit the piston pin (2) from piston surface (A) to the depth

of 2.35 mm (0.092 in) (b).

• After finishing work, check that the piston (3) moves freely.

10. Using suitable tool (A), install piston rings. 

CAUTION:

• Do not damage piston.

• Do not damage piston rings by expanding them exces-

sively.

• Position each ring with the gap as shown referring to the pis-

ton front mark (B).

• Install second ring with the stamped mark (E) facing upward.

11. Install connecting rod bearings to connecting rod and connecting rod cap.

• When installing connecting rod bearings, apply new engine oil to the bearing surface (inside). Do not

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

• Install the bearing in the center position.

NOTE:

There is no stopper tab.

• Check that the oil holes on connecting rod and connecting rod bearing are aligned.

• Install the connecting rod in the dimension (A) as shown.

NOTE:

Install the connecting rod bearing in the center position with

the dimension as shown. For service operation, the center

position can be checked visually.

12. 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 on connecting rod to install. 

• Using Tool (A) or suitable tool, install piston with the front mark

on the piston head facing the front of the engine. 

CAUTION:

• Do not damage mating surface with connecting rod cap.

• Do not damage the cylinder wall or crankshaft pin.

CAUTION:

Check and confirm the tightening angle by using the Tool (A) or protractor. Avoid judgement by

visual inspection without the Tool.

• After tightening connecting rod bolt, check that crankshaft rotates smoothly. 

• Check the connecting rod side clearance. Refer to
