●

When installing, align connecting rod bearing stopper protru-
sion with cutout of connecting rod and connecting rod cap to
install.

●

Ensure the oil hole on connecting rod and that on the corre-
sponding bearing are aligned.

14. Install piston and connecting rod assembly to crankshaft.

●

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

●

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

●

Match the cylinder position with the cylinder number on connecting rod to install.

●

Be sure that front mark on piston head is facing front of engine.

●

Using piston ring compressor (SST) or suitable tool, install
piston with the front mark on the piston head facing the front
of engine.

CAUTION:

Be careful not to damage the cylinder wall and crankshaft
pin, resulting from an interference of the connecting rod big
end.

15. Install connecting rod cap.

●

Match the stamped cylinder number marks on connecting rod
with those on connecting rod cap to install.

●

Be sure that front mark on connecting rod cap is facing front
of engine.

16. Inspect outer diameter of connecting rod bolt. (A/T models) Refer to

EM-164, "CONNECTING ROD BOLT

OUTER DIAMETER (A/T MODELS)"

CAUTION:

Do not reuse connecting rod bolt for M/T models. Replace it with a new one.

17. Tighten connecting rod bolt as follows:

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

Tighten bolts.

Then tighten all bolts 90 to 95 degrees clockwise [target: 90
degrees (Angle tightening)].

CAUTION:

Always use angle wrench [SST: KV10112100 (BT8653-A)].
Avoid tightening based on visual check alone.

●

After tightening bolt, make sure that crankshaft rotates
smoothly.

●

Check the connecting rod side clearance. Refer to

EM-156,

"CONNECTING ROD SIDE CLEARANCE"

18. Install baffle plate to main bearing beam.

●

Install the part shown by the arrow with it facing front of engine.

19. Install new rear oil seal retainer to cylinder block.

●

Apply new engine oil to the oil and dust seal lips.

●

Apply liquid gasket to rear oil seal retainer using tube presser
[SST: WS39930000 (

—

)] as shown in the figure.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

CAUTION:

●

Replace with new parts.

●

Attaching should be done within 5 minutes after coating.

●

Make sure the garter spring is in position and seal lips
not inverted.

NOTE:
Rear oil seal and retainer from a single part are handled as assembly.

20. Install pilot bushing (M/T models) or pilot converter (A/T mod-

els).

●

With drift of the following outer diameter, press-fit as far as it
will go.

●

Press-fit pilot bushing as the dimension in the figure. (M/T
models)

●

Press-fit pilot converter with its chamfer facing crankshaft as
shown in the figure. (A/T models)

21. Install knock sensor.

●

Install knock sensor so that connector faces front of engine.

●

After installing knock sensor, connect harness connector, and
lay it out to rear of engine.

CAUTION:

●

Do not tighten mounting bolts while holding connector.

●

If any impact by dropping is applied to knock sensor,
replace it with new one.

NOTE:

●

Make sure that there is no foreign material on the cylinder
block mating surface and the back surface of knock sensor.

●

Make sure that knock sensor does not interfere with other parts.

22. Note the following, and assemble in the reverse order of disassembly after this step.

Flywheel (M/T models)

●

Ensure the dowel pin is installed in the crankshaft.

●

When installing flywheel to crankshaft, be sure to correctly
align crankshaft side dowel pin and flywheel side dowel pin
hole.

CAUTION:

If these are not aligned correctly, engine runs roughly
and “MIL” turns on.

●

There is a mating mark on the clutch cover side of flywheel.
Refer it during installation.

●

Holding ring gear with ring gear stopper (SST), tighten secur-
ing bolts with TORX socket (size: T55, commercial service
tool).

●

Tighten mounting bolts crosswise over several times.

Drive plate (A/T models)

●

When installing drive plate to crankshaft, be sure to correctly align crankshaft side dowel pin and drive
plate side dowel pin hole.

CAUTION:

If these are not aligned correctly, engine runs roughly and “MIL” turns on.

●

Install drive plate and reinforcement plate as shown in the fig-
ure.

●

Holding ring gear with ring gear stopper [SST: KV10117700
(J44716)].

●

Tighten mounting bolts crosswise over several times.

How to Select Piston and Bearing

NBS002V7

DESCRIPTION

*: For the service parts, the grade for fitting cannot be selected between piston pin and 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.
