7. Install main bearing caps.

Identify main bearing caps by the punched mark. Install cor-
rectly matching the journal No. on the bearing cap and the
journal with the front mark facing forward.

Main bearing caps are commonly processed with the cylinder
block. Therefore, caps and cylinder block should be replaced
as a set.
8. Check the main bearing cap bolts for deformation. Refer to EM-254, "
MAIN BEARING CAP BOLT
DEFORMATION" .
9. With the TORX socket (size: E14, commercial service tool),
tighten the main bearing cap bolts according to the following
procedure:
a. Apply engine oil to the threaded part and seat surface of each
bolt.
b. Tighten all bolts in numerical order shown in the figure.
c. Put alignment marks (with paint) on each bolt and the main
bearing cap, all in the same direction. (When using a protractor)
d. Then, tighten 90 degrees. (angle tightening)
CAUTION:
Always use either the angle wrench (special service tool) or
protractor during angle tightening. Avoid tightening based
on visual checks alone.

After tightening bolts to specified torque, make sure that
crankshaft rotates smoothly.

Check crankshaft end play. Refer to EM-245, "CRANKSHAFT
END PLAY" .
10. Check the outer diameter of connecting rod bolts. Refer to EM-
254, "CONNECTING ROD BOLT DEFORMATION" .
11. Install piston to connecting rod.

Fit snap ring correctly into grooves.
b. Install pistons to connecting rods.

Using the industrial use dryer, heat pistons up to approx. 60 to
70°C (140 to 158°F) until piston pin can be pressed down by
finger touch. Then insert piston pin into piston and connecting
rod from front side of piston toward rear.

Assemble piston and connecting rod with front mark of piston
head and cylinder No. stamped on connecting rod being posi-
tioned as shown in the figure.
c. Install snap ring to front side of piston.

Refer to above step a for precaution on snap ring installation.

After installation, check connecting rods for smooth move-
ment.
12. Use the piston ring expander (commercial service tool) to install piston rings.
CAUTION:
When installing, prevent piston from being damaged.

Install top ring and second ring with punched mark surfaces
facing upward.

Install rings so that three closed gap position 120 degrees
apart one another.

Closed gaps do not need to face in a specific directions, as
long as each are positioned 120 degrees apart.
13. Install connecting rod bearing to connecting rod and cap.

While installing connecting rod bearing, apply engine oil to
bearing surfaces (inside). Do not apply engine oil to rear sur-
faces, but clean them completely.

Align protrusions on connecting rod bearings with connecting
rod cut-outs to install connecting rod bearings.
14. Install piston and connecting rod assembly to crankshaft.

Move crankshaft pin to be assembled to BDC.

Align cylinder position with cylinder No. on connecting rod to
install piston and connecting rod assembly.

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

Using the piston ring compressor (special service tool) or suit-
able tool, install piston and connecting rod assembly with front
mark on piston head facing toward the front side of engine.
CAUTION:

When removing piston and connecting rod assembly,
prevent the big end of connecting rod from interfering with oil jet.

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 caps and mounting nuts.

Align cylinder No. stamped on connecting rod with that on cap
to install connecting rod cap.

Make sure that the front mark on connecting rod cap faces
towards the front of the engine.
16. Tighten connecting rod nuts according to the following procedure:
a. Apply engine oil on bolt threads and seat surface of nuts.
b. Tighten bolts.
c. Loosen completely.
d. Tighten bolts.
e. Tighten 120 degrees. (angle tightening)

Always use either the angle wrench (special service tool)
or protractor during angle tightening. Avoid tightening
based on visual checks alone.

After tightening nuts, make sure that crankshaft rotates
smoothly.

Check connecting rod side clearance. Refer to EM-246,
"CONNECTING ROD SIDE CLEARANCE" .
17. Press fit rear oil seal into rear oil seal retainer.

Using the drift [105 mm (4.13 in) dia.], press fit so that the
dimension is as specified in the figure.

Avoid inclined fitting. Force fit perpendicularly.

PISTON RING SIDE CLEARANCE

Using feeler gauge, measure the side clearance between piston
ring and piston ring groove.
Unit: mm (in)

Align top ring and external surface of piston. Measure lower side
clearance of top ring with top ring pressed onto upper side of
ring groove.

If side clearance exceeds the limit, replace piston ring.

Check clearance again. If side clearance still exceeds the limit,
replace piston.
PISTON RING END GAP

Make sure that cylinder bore diameter is within the specifica-
tions. Refer to EM-250, "
PISTON TO CYLINDER BORE
CLEARANCE" .

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.
Unit: mm (in)

If out of the limit, replace piston ring. If gap still exceeds the limit even with a new ring, re-bore cylinder
and use oversized piston and piston ring. Refer to EM-250, "
PISTON TO CYLINDER BORE CLEAR-
ANCE" .

CONNECTING ROD BIG END INNER DIAMETER

Install connecting rod caps without connecting rod bearings and
tighten connecting rod nuts to the specified torque. Refer to EM-
235, "ASSEMBLY" .

Using inside micrometer, measure connecting rod big end inner
diameter.

Piston Pin Outer Diameter
Use micrometer to measure piston pin outer diameter.
Calculation of Connecting Rod Bushing Clearance
(Connecting rod bushing clearance) = (Connecting rod bushing inner diameter) − (Piston pin outer diameter)

If it exceeds the limit, replace connecting rod and/or piston and piston pin assembly. Refer to EM-242,
"HOW TO SELECT CONNECTING ROD BEARING" and/or EM-242, "HOW TO SELECT PISTON" .
CYLINDER BLOCK TOP SURFACE DISTORTION

Using scraper, remove gasket installed onto cylinder block sur-
face. Remove contamination such as engine oil, scale, and car-
bon.
CAUTION:
Keep broken pieces of gasket clear of engine oil and engine
coolant passages.

Use straightedge and feeler gauge to check block upper surface
for six distortion.

If it exceeds the limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER

Without installing main bearings, install main bearing caps, and
tighten bolts to the specified torque. Refer to EM-235, "
ASSEM-
BLY" .

Measure the inner diameter of main bearing housing with a bore
gauge.

If the measurement is out of the standard, replace cylinder block
and main bearing caps.
