Assemble so that the front mark on the piston head and the oil
holes and the cylinder number on connecting rod are posi-
tioned 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, make sure that connecting rod moves
smoothly.
9. Using 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 refer-
ring to the piston front mark.

Install second ring with the stamped surface facing upward.
NOTE:
If there is no stamped mark on piston ring, no specific orienta-
tion is required for installation.
10. Inspect outer diameter of connecting rod bolts. Refer to EM-107, "
CONNECTING ROD BOLT OUTER
DIAMETER" .
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 new engine oil to the back surface, but thoroughly clean it.

When installing, align the connecting rod bearing stopper pro-
trusion with the 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.
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 journal.

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

Install drive plate, reinforcement plate and pilot converter as
shown in the figure.

Using drift of 33 mm (1.30 in) in diameter, press-fit pilot con-
verter into the end of crankshaft until it stops.
16. Install knock sensor.

Install knock sensor with connector facing lower left by 45
degrees as shown in the figure.
CAUTION:

Do not tighten mounting bolt while holding the connec-
tor.

If any impact by dropping is applied to knock sensor,
replace it with a 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.
17. Install crankshaft position sensor (POS).
18. Assemble in the reverse order of disassembly after this step.
How to Select Piston and Bearing BBS0059H
DESCRIPTION
*For the service parts, the grade for fitting cannot be selected between piston pin and connecting rod. (Only grade “0” 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.

HOW TO SELECT PISTON
When New Cylinder Block is Used

Check the cylinder bore grade on rear left side of cylinder block,
and select piston of the same grade.

If there is a corrected stamp mark on the cylinder block, use it as
a correct reference.
When Cylinder Block is Reused
1. Measure the cylinder bore inner diameter. Refer to EM-103, "Cylinder Bore Inner Diameter" .
2. Determine the bore grade by comparing the measurement with the values under the cylinder bore inner
diameter of the “Piston Selection Table”.
3. Select piston of the same grade.
Piston Selection Table
Unit: mm (in)
NOTE:

There is no piston grade “1”.

Piston is available together with piston pin as an assembly.

The piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts,
no grades can be selected. (Only grade “0” is available.)
HOW TO SELECT CONNECTING ROD BEARING
When New Connecting Rod and Crankshaft are Used
1. Apply connecting rod big end diameter grade stamped on con-
necting rod side face to the row in the “Connecting Rod Bearing
Selection Table”.

CAUTION:
In grinding crankshaft pin to use undersize bearings, keep the

HOW TO SELECT MAIN BEARING
When New Cylinder Block and Crankshaft are Used
1. “Main Bearing Selection Table” rows correspond to main bearing
housing grade on rear left side of cylinder block.

If there is a corrected stamp mark on cylinder block, use it as
a correct reference.
2. Apply main journal diameter grade stamped on crankshaft front
side to column in the “Main Bearing Selection Table”.
3. Read the symbol at the cross point of selected row and column in the “Main Bearing Selection Table”.
CAUTION:
There are two main bearing selection tables. One is for odd-numbered journals (No. 1, 3 and 5) and
the other is for even-numbered journals (No. 2 and 4). Make certain to use the appropriate table.
This is due to differences in the specified clearances.
4. Apply the symbol obtained to the “Main Bearing Grade Table” to select main bearing.
NOTE:
Service part is available as a set of both upper and lower.
When Cylinder Block and Crankshaft are Reused
1. Measure the dimensions of the cylinder block main bearing housing inner diameter and crankshaft main
journal diameter individually. Refer to EM-103, "
MAIN BEARING HOUSING INNER DIAMETER" and
EM-104, "
CRANKSHAFT MAIN JOURNAL DIAMETER" .
2. Apply the measured dimension to the “Main Bearing Selection Table”.

When replacing piston and piston pin assembly, refer to EM-92, "HOW TO SELECT PISTON" .
NOTE:

Piston is available together with piston pin as an assembly.

The piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service
parts, no grades can be selected. (Only grade “0” is available.)
PISTON RING SIDE CLEARANCE

Measure the side clearance of piston ring and piston ring groove
with feeler gauge.

If the measured valve exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
replace piston also.
PISTON RING END GAP

Make sure that cylinder bore inner diameter is within specifica-
tion. Refer to EM-103, "
Cylinder Bore Inner Diameter" .

Lubricate with new engine oil to piston and piston ring, and then
insert piston ring until middle of cylinder with piston, and mea-
sure piston ring end gap with feeler gauge.

If the measured valve exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
re-bore cylinder inner wall and use oversized piston and piston rings.Standard:
Top ring : 0.045 - 0.080 mm (0.0018 - 0.0031 in)

Piston Pin Outer Diameter
Measure the outer diameter of piston pin with micrometer.
Connecting Rod Bushing Oil Clearance
(Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) – (Piston pin outer diame-
ter)

If the measured value is out of the standard, replace connecting rod assembly and/or piston and piston pin
assembly.

If replacing piston and piston pin assembly, refer to EM-92, "HOW TO SELECT PISTON" .

If replacing connecting rod assembly, refer to EM-105, "CON-
NECTING ROD BEARING OIL CLEARANCE" to select con-
necting rod bearing.
