c. Be sure to install main bearings in the correct direction.
+Make sure those with oil holes or oil grooves are mounted on
the cylinder block side, and those without oil holes or oil
grooves are on the main cap side.
+Before installing, apply engine oil on the front (inner) surfaces
of bearings. Do not apply oil to the back surfaces, but thor-
oughly clean them.
+Align stopper notches on bearings and install.
+Check the oil holes on cylinder block and those on bearings
are aligned.

5. Install crankshaft to cylinder block.
+Make sure crankshaft rotates smoothly by hand.
6. Install main bearing caps.
+Identify main bearing caps by the punched mark. Install
correctly, matching the journal No. on the bearing cap and the
journal, with the front mark facing forward.
+Main bearing caps are commonly processed with the cylinder
block. Therefore, caps and cylinder block should be replaced
as a set.

7. Check the main bearing cap bolts for deformation.
Refer to EM-153, ªMAIN BEARING CAP BOLT DEFORMA-
TIONº.
8. Tighten the main bearing cap bolts according to the following
procedure:

bearing cap, all in the same direction. (when using a protrac-
tor)
d. Then, tighten 90É to 95É [target: 90É].
+Always use either an angle wrench (SST) or protractor
during angular tightening. Avoid tightening based on
visual checks alone.

+Install insulator according to the shape of the block, and secure
by placing the bracket against the insulator. (Not installed on
some models)
+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.
+Check the protruding distance of the dowel pin for fuel injec-
tion pump.
Standard: 13.0 - 15.0 mm (0.512 - 0.591 in)
19. Install parts to the engine in the reverse order of disassembly.
+Tighten bolts securing brackets of auxiliary components (A/C
compressor, alternator) to the specified torque.
: 57 - 65 N´m (5.8 - 6.7 kg-m, 42 - 48 ft-lb)
20. Remove engine from engine stand in the reverse order of
assembly.
21. Install flywheel.
+Holding ring gear with ring stopper (SST), tighten securing
bolts with TORX-socket (size: Q8 E20, Commercial Service
Tool).
+Tighten bolts uniformly in a crisscross manner.

Checking Fuel LinesNJFE0009Inspect fuel lines and tank for improper attachment, leaks, cracks,
damage, loose connections, chafing or deterioration.
If necessary, repair or replace faulty parts.
MMA104A
CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end is
3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.
Removal and InstallationNJFE0004WARNING:
When replacing fuel line parts, be sure to observe the following.
+Put a ªCAUTION: FLAMMABLEº sign in workshop.
+Be sure to furnish workshop with a CO
2fire extinguisher.
+Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
CAUTION:
+Before removing fuel line parts, carry out the following procedures:
a) Put drained fuel in an explosion-proof container and put the lid on securely.
b) Release fuel pressure from fuel line. Refer to EC-40, ªFuel Pressure Releaseº.
c) Disconnect battery ground cable.
+Always replace O-ring and clamps with new ones.
+Do not kink or twist tubes when they are being installed.
+Do not tighten hose clamps excessively to avoid damaging hoses.
+After installing tubes, run engine and check for fuel leaks at connections.

Checking Exhaust SystemNJFE0010Check exhaust pipes, muffler and mounting for improper
attachment, leaks, cracks, damage, chafing or deterioration.
Removal and InstallationNJFE0005CAUTION:
+Always replace exhaust gaskets with new ones when
reassembling.
+With engine running, check all tube connections for
exhaust gas leaks, and entire system for unusual noises.
+Check to ensure that mounting brackets and mounting
insulators are installed properly and free from undue
stress. Improper installation could result in excessive
noise or vibration.
+Discard any heated oxygen sensor which has been
dropped from a height of more than 0.5 m (19.7 in) onto a
hard surface such as a concrete floor; use a new one.
+Before installing a new oxygen sensor, clean exhaust sys-
tem threads using oxygen sensor thread cleaner tool and
apply anti-seize lubricant.
+Do not overtorque the oxygen sensor. Doing so may
cause damage to the oxygen sensor, resuiting in the MIL
coming on.
+Be sure to use genuine exhaust system parts which are
designed especially for heat resistance, corrosion
resistance, and shape.
+Perform the operation with the exhaust system fully
cooled down because the system will be heated just after
the engine stops.
+Be careful not to cut your hand on the insulator edge.

Removal and InstallationNJFE0013CAUTION:
+Do not disassemble the accelerator pedal assembly. Do not remove the sensors and the switches
from the assembly.
+Avoid impact from dropping etc. during handling.
+Be careful to keep the assembly away from water.
+Do not adjust the adjusting screw (painted white) of the accelerator work unit.
+When the connector of the accelerator sensor is disconnected, reconnect the connector, and touch
ªCLEARº in ªOFF ACCEL PO SIGº of the active test using the CONSULT-II. Or, warm up the engine,
then leave it idling for approximately 10 minutes.

InspectionNJFE0020+Check that the accelerator pedal moves smoothly within the
whole operation range.
+Check that the accelerator pedal securely returns to the origi-
nal position.
+Check that the drum of the accelerator work unit can be fully
opened.
+Refer to EC-641, ªBasic Inspectionº for the inspection of the
accelerator work unit and the accelerator pedal switch.
