9. Restart tightening of lower cylinder block bolts with the following
procedure.
NOTE:
Step “a ”and “b” have been completed before installation of rear
oil seal (step 7).
a. Step “a” has been completed before installation of rear oil seal.
b. Step “b” has been completed before installation of rear oil seal.
c. Tighten M10 (0.39 in) bolts to 60 to 65° (target: 60°) in order
from No. 1 to 10.
d. Tighten M8 (0.31 in) bolts to 19.6 to 24.5 N·m (2.0 to 2.5 kg-m,
15 to 18 ft-lb) in order from No. 11 to 22.
CAUTION:
In step “c”, use an angle wrench (special service tool) or
protractor to check tightening angle. Do not make judgment
by visual inspection.
●After installing mounting bolts, make sure that crankshaft can
be rotated smoothly by hand.
●Wipe off completely any protruding liquid gasket on front side
of engine.
●Check crankshaft side clearance. Refer to EM-88, "CRANK-
SHAFT END PLAY" .
10. Install the piston to the connecting rod.
a. Using a snap ring pliers, install the snap ring to the grooves of
the piston rear side.
●Insert it fully into groove to install.
b. Install the piston to the connecting rod.
●Using an industrial drier or similar tool, heat the piston until the piston pin can be pushed in by hand
without excess force [approx. 60 to 70 °C (140 to 158 °F)]. From the front to the rear, insert the piston
pin into the piston and the connecting rod.
●Assemble so that the front mark on the piston crown and the
oil holes and the cylinder No. on the connecting rod are posi-
tioned as shown in the figure.
c. Install the snap rings to the front of the piston.
● After installing, check that the connecting rod moves
smoothly.
11. Using a piston ring expander, install the piston rings.
CAUTION:
Be careful not to damage the piston.
●Position each ring with the gap as shown in the figure refer-
ring to the piston front mark.
●Install the top ring and the second ring with the stamped sur-
face facing upward.

12. Install the connecting rod bearings to the connecting rod and the
connecting rod cap.
●When installing the connecting rod bearings, apply engine oil
to the bearing surface (inside). Do not apply engine oil to the
back surface, but thoroughly clean it.
●When installing, align the connecting rod bearing stopper pro-
trusion with the notch of the connecting rod to install.
●Check the oil holes on the connecting rod and those on the
corresponding bearing are aligned.
13. Install the piston and connecting rod assembly to the crankshaft.
●Position the crankshaft pin corresponding to the connecting
rod to be installed onto the bottom dead center.
●Apply engine oil sufficiently to the cylinder bore, piston and
crankshaft pin.
●Match the cylinder position with the cylinder No. on the con-
necting rod to install.
●Using a piston ring compressor, install the piston with the front
mark on the piston crown 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.
14. Install the connecting rod cap.
●Match the stamped cylinder number marks on the connecting
rod with those on the cap to install.
15. Tighten the connecting rod bolt as follows.
a. Apply engine oil to the threads and seats of the connecting rod
bolts.
b. Tighten bolts to 18.6 to 20.6 N·m (1.9 to 2.1 kg-m, 14 to 15 ft-lb).
c. Put mating (with paint) on each bolt and connecting rod cap, all
in the same direction (when using a protractor).
d. Then tighten all bolts 90 to 95 degrees clockwise (target: 90
degrees) (Angle tightening).
CAUTION:
Always use either an angle wrench or protractor. Avoid
tightening based on visual check alone.
●After tightening the bolt, make sure that the crankshaft rotates smoothly.
●Check the connecting rod side clearance. Refer to EM-89, "CONNECTING ROD SIDE CLEARANCE" .

●Using drift of 33 mm (1.30 in) in diameter, push pilot converter
into the end of crankshaft (A/T model).
17. Install knock sensor.
●Make sure that there is no foreign material on the cylinder
block mating surface and the back surface of the knock sen-
sor.
●Install sensor with connector facing lower left by 45° as
shown.
●D o n o t t i g h t e n t h e m o u n t i n g b o l t s w h i l e h o l d i n g t h e c o n n e c t o r.

parts.
CAUTION:
If any impact by dropping is applied to the knock sensor,
replace it with new one.
18. Install crankshaft position (POS) sensor.
19. Install followings in reverse order of removal.
How to Select Piston and Bearing EBS00KNV
DESCRIPTION
*For the service parts, the grade for fitting cannot be selected between a piston pin and a connecting rod.
(Only 0 grade is available.) The information at the shipment from the plant is described as a reference.
●The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
●For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the
measurement with the values of each selection table.
●For details of the measurement method of each part, the reuse standards and the selection method of the
selective fitting parts, refer to the text.
