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 
and front mark 

 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.

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 60 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] 

 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-231, "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 

 on the piston head and the

oil hole 

 and the cylinder number 

 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:

• Be careful not to damage piston.
• Be careful not to 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 

 and lower 

 to connect-

ing rod 

 and connecting rod cap 

.

• Install the connecting rod in the dimension shown in the figure. 
• Check that connecting rod bearing oil hole 

 is completely in

the inside of connecting rod oil hole chamfered area 

.

• 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 connecting rod and connecting rod cap as shown in

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

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 

 on

connecting rod to install. 

• Install so that front mark 

 on the piston head faces the front

of engine.

• Using a piston ring compressor [SST: EM03470000] 

 or suit-

able tool, install piston with the front mark on the piston 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 

 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 

 of the

joint between connecting rod 

 and connecting rod cap

 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-231, "Inspection"

.

a.

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

b.

Tighten connecting rod cap bolts.

c.

Completely loosen connecting rod cap bolts.

Then turn all connecting rod cap bolts 60 degrees clockwise (angle tightening).

CAUTION:

Check and confirm the tightening angle by using an angle
wrench [SST: KV10112100] 

 or protractor. Never judge by

visual inspection without the tool.

• After tightening connecting rod cap bolt, check that crankshaft rotates smoothly. 
• Check the connecting rod side clearance. Refer to
