IAlign piston rings so that end gaps are positioned as
shown.
CRANKSHAFTNCEM0027S021. Install signal plate to crankshaft.
2. Set main bearings in their proper positions on cylinder block
and main bearing cap.
IConfirm that correct main bearings are selected by using
Method A or Method B. Refer to EM-57.
IApply new engine oil to bearing surfaces.
3. Install crankshaft and main bearing caps and tighten bolts to
the specified torque.
IApply new engine oil to the bolt thread and seat surface.
IPrior to tightening bearing cap bolts, shift crankshaft back
and forth to properly seat the bearing caps.
ITighten bearing cap bolts gradually in two or three stages.
Start with center bearing and move outward as shown in
figure.
IAfter securing bearing cap bolts, make sure crankshaft
turns smoothly by hand.

4. Measure crankshaft end play.
Crankshaft end play:
Standard
0.060 - 0.260 mm (0.0024 - 0.0102 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.
IConfirm that correct bearings are used. Refer to EM-58.
IInstall bearings so that oil hole in connecting rod aligns
with oil hole of bearing.
IApply new engine oil to bolt threads and bearing surfaces.
6. Install pistons with connecting rods.
a. Install them into corresponding cylinders with Tool.
IMake sure connecting rod does not scratch cylinder wall.
IMake sure connecting rod bolts do not scratch crankshaft
pin journals.
IArrange so that front mark on piston head faces engine.
IApply new engine oil to piston rings and sliding surface
of piston.
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:
ITighten to 13.72 to 15.68 N×m (1.399 to 1.599 kg-m, 10.120
- 11.566 ft-lb).
ITurn 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 (0.0205 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.
IUse Genuine Liquid Gasket or equivalent.
IApply around inner side of bolt holes.
9. Install crankshaft positon sensor (POS).
10. Install knock sensor.
