12. Install connecting rod bearings to connecting rods and caps.
●While installing connecting rod bearings, apply engine oil to
bearing surfaces (inside). Do not apply engine oil to rear sur-
faces, but clean them completely.
●Align stoppers on connecting rod bearings with connecting
rod stopper notches to install connecting rod bearings.
13. 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.
●Using piston ring compressor, install piston and connecting
rod assembly with front mark on piston crown facing toward
the front side of engine.
CAUTION:
When installing piston and connecting rod assembly, pre-
vent the big end of connecting rod from interfering with
oil jet.
14. 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.
15. Tighten connecting rod nuts according to the following proce-
dure:
a. Apply engine oil on bolt threads and seat surface of nuts.
b. Tighten to 29 to 30 N·m (2.9 to 3.1 kg-m, 21 to 22 ft-lb).
c. Loosen completely to 0 N·m (0 kg-m, 0 in-lb).
d. Tighten to 19 to 20 N·m (1.9 to 2.1 kg-m, 14 to 15 ft-lb).
e. Tighten 120° to 125° [target: 120°]. (angular tightening)
●Always use either an angle wrench (SST) or protractor
during angular tightening. Avoid tightening based on
visual checks alone.
●After tightening nuts, check that crankshaft rotates smoothly.
●Check connecting rod side clearance. Refer to EM-210,
"CONNECTING ROD SIDE CLEARANCE" .
16. Press fit rear oil seal into rear oil seal retainer.
●Using a 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.

17. Install rear oil seal and retainer assembly.
●Apply a continuous bead of liquid gasket to rear oil seal and
retainer assembly as shown in the figure.
18. Press fit pilot bushing into flywheel.
●Using drift with outer diameter of 19 mm (0.75 in), press fit
pilot bushing until it stops.
19. Install fuel supply pump bracket.
●Align the bracket with the dowel pins on the block to install.
●The two bolts used for dowel pins have a longer shanks than
the other two.
20. Install parts to the engine in the reverse order of disassembly.
21. Remove engine from engine stand in the reverse order of
assembly.
22. Install flywheel.
●When installing flywheel to crankshaft, be sure to correctly
align crankshaft side dowel pin and flywheel side dowel pin-
hole.

Piston Pin Outer Diameter
Use micrometer to measure piston pin outer diameter.
Calculation of Connecting Rod Bushing Clearance
(Connecting rod small end bushing clearance) = (Connecting rod small end inner diameter) − (Piston pin outer
diameter)
●If out of specifications, replace connecting rod and/or piston and piston pin assembly. Refer to EM-207,
"HOW TO SELECT CONNECTING ROD BEARING" .
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 distortion.
MAIN BEARING HOUSING INNER DIAMETER
●Without installing main bearings, install main bearing caps, and
tighten bolts to the specified torque.
●Measure the inner diameter of main bearing housing with a bore
gauge.
●If the measurement is out of the specified range, replace cylin-
der block and main bearing caps.Standard : 27.994 - 28.000 mm (1.1021 - 1.1024 in)

CRANKSHAFT RUNOUT
●Place V-block onto surface plate to support journals at both ends
of crankshaft.
●Position dial indicator vertically onto No. 3 journal.
●Rotate crankshaft to read needle movement on dial indicator.
(Total indicator reading)
CONNECTING ROD BEARING OIL CLEARANCE
Method by Measurement
●Install connecting rod bearings to connecting rod and cap, and
tighten connecting nuts to the specified torque. Use inside
micrometer to measure connecting rod bearing inner diameter.
(Bearing clearance) = (Connecting rod bearing inner diameter) −
(Crankshaft pin outer diameter)
●If out of specifications, check connecting rod big end inner diam-
eter and crankshaft pin outer diameter, and select appropriate
connecting rod bearing to adjust clearance to specifications.
Refer to EM-207, "
HOW TO SELECT CONNECTING ROD
BEARING" .
Method Using Plastigage
●Remove contamination such as engine oil, dust completely from
crankshaft pins and each bearing surface.
●Cut plastigage slightly shorter than bearing width, place it in
crankshaft direction, avoiding oil holes.
●Install connecting rod bearings to caps, and tighten connecting
rod nuts to the specified torque.
CAUTION:
Never rotate crankshaft.
●Remove connecting rod caps and bearings, and measure plasti-
gage width using scale on plastigage bag.
CAUTION:
If out of specification, take same action mentioned in “Method by Measurement”.
MAIN BEARING OIL CLEARANCE
Method by Measurement
●Install main bearings to the cylinder block and bearing cap, and tighten the bolts to the specified torque.
Then, measure the inner diameter of the main bearings.
(Bearing clearance) = (Bearing inner diameter) − (Crankshaft journal outer diameter)
●If out of specification, check main bearing housing inner diameter and crankshaft journal outer diameter,
and select appropriate main bearing to adjust clearance to specifications. Refer to EM-208, "

Method Using Plastigage
●Remove contamination such as engine oil and dust completely
from crankshaft journals and each bearing surface.
●Cut plastigage slightly shorter than bearing width. Place it in
crankshaft turning direction, avoiding oil holes.
●Install main bearings and bearing cap and tighten to the speci-
fied torque.
CAUTION:
Never rotate crankshaft.
●Remove main bearings and bearing caps, and measure plasti-
gage width using scale on plastigage bag.
CAUTION:
If out of specification, take same action mentioned in “Method by Measurement”.
MAIN BEARING CRUSH HEIGHT
●When the bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bear-
ing must protrude.
●If out of specification, replace main bearings.
MAIN BEARING CAP BOLT DEFORMATION
●Measure the outer diameter of threaded area, d1 and d2, at the
points specified in the figure.
●When the necked point is identified at a point other than where
specified, measure at the point as d2.
●Calculate the difference between d1 and d2.
CONNECTING ROD BOLT DEFORMATION
●Install nuts to connecting rod bolts. Check that the nut can be
screwed smoothly on bolt threads by hand to the last thread on
the bolt.
●If the nut does not screw in smoothly, measure the outer diame-
ter of the bolt thread at the point specified in the figure.
●If a necked point is identified, measure at that point.
●If the measurement exceeds the limit, replace connecting rod
bolts and nuts.
