15. Tighten the connecting rod nuts as follows:
a. Apply engine oil to the threads and seats of connecting rod bolts
and nuts.
b. Tighten nuts.
c. Then tighten all nuts 60 degrees clockwise. (Angle tightening)
CAUTION:
Use angle wrench (SST) to check tightening angle. Do not
make judgment by visual inspection.

After tightening nuts, make sure that the crankshaft rotates
smoothly.

Check the connecting rod side clearance. Refer to EM-256, "CONNECTING ROD SIDE CLEARANCE"
.
16. Install knock sensor.

Install it with its connector facing the rear of engine.

Install the sub-harness with its shorter branch line to the right
bank.
CAUTION:

Do not tighten mounting bolts while holding connector.

If any impact by dropping is applied to knock sensor,
replace it with new one.
NOTE:

Make sure that there is no foreign material on the cylinder
block mating surface and the back surface of the knock sen-
sor.

Make sure that the knock sensor does not interfere with other parts.
17. Install in the reverse order of removal after this step.
18. Remove engine assembly from engine stand.
19. Install drive plate.

Align guide pin of crankshaft rear end with pin holes of each
parts to install.

Install drive plate, reinforcement plate and pilot converter (if
not installed in step 4) as shown in the figure.

Face chamfered or rounded edge side to crankshaft.

Holding ring gear with ring gear stopper [SST: J-45476].

Tighten mounting bolts crosswise over several times.

When install pilot converter, using drift [outer diameter:
approx. 35 mm (1.38 in)]. Press-fit as far as it will go. : 14.7 N·m (1.5 kg-m, 11 ft-lb)

Checking Exhaust SystemABS005Z5
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage or deterioration.

If anything is found, repair or replace damaged parts.
Removal and InstallationABS005Z6
CAUTION:

Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.

Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.

Be careful not to cut your hand on the heat insulator edge.

Tighten main muffler mounting bracket bolts in numerical order
as shown in the figure.
CAUTION:

Always replace exhaust tube gaskets with new ones when reassembling.

If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat
insulator, remove them.

When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.

Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gas leakage.

Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehi-
cle side. Check each part for unusual interference, and then tighten them to the specified torque.

When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.
INSPECTION AFTER INSTALLATION

Make sure clearance between tail tube and bumper is even.

With engine running, check exhaust tube joints for gas leakage and unusual noises.

Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.

Checking Fuel LinesABS005YX
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionsABS005YY
WARNING:
When replacing fuel line parts, be sure to observe the following.

Put a “CAUTION: INFLAMMABLE” sign in the workshop.

Be sure to work in a well ventilated area and furnish workshop with a CO2 fire extinguisher.

Do not smoke while servicing fuel system. Keep open flames and sparks away from the work area.
CAUTION:

Before removing fuel line parts, carry out the following procedures:
–Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
–Release fuel pressure from the fuel lines. Refer to EC-51, "FUEL PRESSURE RELEASE" (VQ35DE)
or EC-700, "
FUEL PRESSURE RELEASE" (VK45DE).
–Disconnect negative battery terminal.

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 connecting fuel tube quick connectors, make sure
quick connectors are secure.
Ensure that connector and resin tube do not contact any
adjacent parts.

After installing tubes, make sure there is no fuel leakage at
connections in the following steps.
–Apply fuel pressure to fuel lines with turning ignition switch
“ON” (with engine stopped). Then check for fuel leaks at
connections.
–Start engine and rev it up and check for fuel leaks at con-
nections.

Use only a genuine NISSAN fuel filler cap as a replacement.
If an incorrect fuel filler cap is used, the “MIL” may come
on.

For servicing “Evaporative Emission System” parts, refer to
EC-643, "
EVAPORATIVE EMISSION SYSTEM" (VQ35DE) or
EC-1320, "
EVAPORATIVE EMISSION SYSTEM" (VK45DE).

For servicing“On Board Refueling Vapor Recovery (ORVR)”
parts, refer to EC-650, "
ON BOARD REFUELING VAPOR
RECOVERY (ORVR)" (VQ35DE) or EC-1327, "ON BOARD
REFUELING VAPOR RECOVERY (ORVR)" (VK45DE).
