Nissan Primera P11. Manual — part 415
2.
Install crankshaft and main bearing caps and tighten bolts to
the specified torque and in numerical order as shown in the
figure.
I
Apply new engine oil to thread of bearing cap bolts.
I
Prior to tightening bearing cap bolts, shift crankshaft back
and forth to properly seat the bearing cap.
I
Tightening procedure
a.
Tighten all bolts to 32 to 38 N·m (3.3 to 3.9 kg-m, 24 to
28 ft-lb).
b.
Turn all bolts 30 to 35 degrees clockwise with Tool or
suitable angle wrench.
I
If an angle wrench is not available, mark all bearing cap
bolts on the side facing engine rear. Then, turn each bolt
specified degrees clockwise. Confirm angle of degrees
with a graduator, not by eye-measurement.
I
After securing bearing cap bolts, make sure crankshaft
turns smoothly by hand.
3.
Measure crankshaft end play.
Crankshaft end play:
Standard
0.10 - 0.26 mm (0.0039 - 0.0102 in)
Limit
0.30 mm (0.0118 in)
If beyond the limit, replace thrust bearings with new ones.
4.
Install connecting rod bearings in connecting rods and con-
necting rod caps.
I
Confirm that correct bearings are used. Refer to “Inspec-
tion”.
I
Install bearings so that oil hole in connecting rod aligns
with oil hole of bearing.
I
Apply new engine oil to bolt threads and bearing surfaces.
5.
Install pistons with connecting rods.
a.
Install them into corresponding cylinders with Tool.
I
Be careful not to scratch cylinder wall by connecting rod.
I
Arrange so that front mark on piston head faces toward
front of engine.
I
Apply new engine oil to piston rings and sliding surface
of piston.

b.
Install connecting rod caps.
Tighten connecting rod cap nuts to the specified torque.
Tightening procedure:
1) Tighten nuts to 14 to 16 N·m (1.4 to 1.6 kg-m, 10
to 12 ft-lb).
2) Turn nuts 60 to 65 degrees clockwise with
angle wrench. If angle wrench is not available,
tighten nuts to 38 to 44 N·m (3.9 to 4.5 kg-m, 28
to 33 ft-lb).
6.
Measure connecting rod side clearance.
Connecting rod side clearance:
Standard
0.20 - 0.35 mm (0.0079 - 0.0138 in)
Limit
0.50 mm (0.0197 in)
If beyond the limit, replace connecting rod and/or crankshaft.
7.
Install rear oil seal retainer.
a.
Before installing rear oil seal retainer, remove all traces of liq-
uid gasket from mating surface using a scraper.
●
Also remove traces of liquid gasket from mating surface of
cylinder block.
b.
Apply a continuous bead of liquid gasket to mating surface of
rear oil seal retainer.
●
Use Genuine Liquid Gasket or equivalent.
