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.

Piston Pin Outer Diameter
Using micrometer, measure piston pin outer diameter.
Calculation of Piston to Piston Pin Clearance
(Piston pin clearance) = (Piston pin hole inner diameter) − (Piston pin outer diameter)
●If clearance is exceeds specification, replace either or both piston/piston pin assembly.
PISTON RING SIDE CLEARANCE
●Using feeler gauge, measure 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
●Check that cylinder bore diameter is within specifications. Refer
to EM-214, "

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
