3. Install crankshaft and main bearing caps and tighten bolts to
the specified torque.
+Apply new engine oil to the bolt thread and seat surface.
+Prior to tightening bearing cap bolts, shift crankshaft back
and forth to properly seat the bearing caps.
+Tighten bearing cap bolts gradually in two or three stages.
Start with center bearing and move outward as shown in
figure.
+After securing bearing cap bolts, make sure crankshaft
turns smoothly by hand.

4. Measure crankshaft end play.
Crankshaft end play:
Standard
0.060 - 0.220 mm (0.0024 - 0.0087 in)
Limit
0.3 mm (0.012 in)
If beyond the limit, replace thrust bearing with new ones.

5. Install connecting rod bearings in connecting rods and con-
necting rod caps.
+Confirm that correct bearings are used. Refer to EM-60.
+Install bearings so that oil hole in connecting rod aligns
with oil hole of bearing.
+Apply new engine oil to bolt threads and bearing surfaces.
SEM942F
6. Install pistons with connecting rods.
a. Install them into corresponding cylinders with Tool.
+Make sure connecting rod does not scratch cylinder wall.
+Make sure connecting rod bolts do not scratch crankshaft
pin journals.
+Arrange so that front mark on piston head faces engine.
+Apply new engine oil to piston rings and sliding surface
of piston.
SEM943F
b. Install connecting rod caps.
Apply new engine oil to bolt threads and nut seating surfaces.
Tighten connecting rod cap nuts in the following procedure:
+Tighten to 13.72 to 15.68 N´m (1.399 to 1.599 kg-m, 10.120
to 11.566 ft-lb).
+Turn nuts to 35É to 40É degrees clockwise with an angle
wrench. If an angle wrench is not available, tighten nuts to
23 to 28 N´m (2.3 to 2.9 kg-m, 17 to 21 ft-lb).

7. Measure connecting rod side clearance.
Connecting rod side clearance:
Standard
0.200 - 0.470 mm (0.0079 - 0.0185 in)
Limit
0.5 mm (0.020 in)
If beyond the limit, replace connecting rod and/or crank-
shaft.

8. Install rear oil seal retainer.
a. Before installing rear oil seal retainer, remove old liquid gasket
from cylinder block and retainer.
b. Apply a continuous bead of liquid gasket to rear oil seal
retainer.
+Use Genuine Liquid Gasket or equivalent.
+Apply around inner side of bolt holes.
9. Install crankshaft positon sensor (POS).

Parts Requiring Angular TighteningNJEM0047+Use an angle wrench for the final tightening of the following
engine parts:
a) Cylinder head bolts
b) Main bearing cap bolts
c) Connecting rod cap nuts
d) Crankshaft pulley bolt
+Do not use a torque value for final tightening.
+The torque value for these parts are for a preliminary step.
+Ensure thread and seat surfaces are clean and coated with
engine oil.
SEM164F
Liquid Gasket Application ProcedureNJEM00481.Use a scraper to remove all traces of old liquid gasket
from mating surfaces and grooves. Also, completely clean
any oil from these areas.
2.Apply a continuous bead of liquid gasket to mating sur-
faces. (Use Genuine Liquid Gasket or equivalent.)
+Be sure liquid gasket diameter is as specified.
AEM080
3.Apply liquid gasket around the inner side of bolt holes
(unless otherwise specified).
4.Assembly should be done within 5 minutes after coating.
5.Wait at least 30 minutes before refilling engine oil and
engine coolant.
