TIMING CHAIN
4. Install timing chains and related parts.
 Align the mating mark on each sprocket and timing chain for installation.NOTE:
Before installing chain tensioner, it is possible to change the position of mating mark on timing chain for
that on each sprocket for alignment.
CAUTION:
For the above reason, after the mating marks ar e aligned, keep them aligned by holding them
with a hand.
 Install slack guides and tension guides onto correct si de by checking with identification mark on surface.
 Install chain tensioner with plunger fixed as described in its removal.
CAUTION:
 Before and after the installation of chain tens ioner, make sure that the mating mark on timing
chain is not out of alignment.
 After installing chain tensioner, remove stoppe r pin to release tensioner. Make sure tensioner
is released.
 To avoid chain-link skipping of timing chain, do not move crankshaft or camshafts until front
cover is installed.
5. Perform the same procedure as for right bank, install timing chain and related parts on left side.
6. Install oil pump. Refer to LU-29
.
7. Install oil pump drive spacer as follows:
a. Insert oil pump drive spacer according to the directions of crank- shaft key and the two flat surfaces of oil pump inner rotor.
 If the positional relationship does not allow the insertion, rotate
oil pump inner rotor with a finger to allow spacer.
b. After confirming that the position of each part is in correct condi- tion to allow for spacer, force fit spacer by lightly tapping with
plastic hammer until it contacts and does not go further.
8. Install front oil seal on front cover.  Apply new engine oil to both oil seal lip and dust seal lip.

 Lightly tapping its center with plastic hammer, insert pulley.CAUTION:
Do not tap pulley on the side surface where belt is installed (outer circumference).
c. Apply engine oil onto threaded parts of crankshaft pulley bolt and seating area.
d. Tighten crankshaft pulley bolt.
e. Put a paint mark on crankshaft pulley aligning with angle mark on crankshaft pulley bolt.
f. Further tighten by 90 degrees. (Angle tightening)  Check the tightening angle by referencing to the notches. Theangle between two notches is 90 degrees.
15. Rotate crankshaft pulley in normal direction (clockwise when viewed from engine front) to confirm it turns smoothly.
16. Install in the reverse order of removal after this step. NOTE:

5. Install crankshaft to cylinder block.
 While turning crankshaft by hand, make sure it turns smoothly.
6. Install main bearing caps.  Align the identification number to the journal position to install.
 Install the upper side of the identification number facing thefront of engine. (The number shall be read correctly from the
rear of engine.)
 Using plastic hammer or similar tool, tap them lightly to seat them on the installation position.
NOTE:
Main bearing cap cannot be replaced as a single parts, because
it is machined together with cylinder block.
7. Install each main bearing cap bolt as follows:
a. Apply new engine oil to threads and seating surface of main bearing cap bolts, and tighten all bolts temporarily.
b. Tighten main bearing cap bolt (M12) in order of 1 to 10.

< SERVICE INFORMATION >
SERVICE INFORMATION FOR ELECTRICAL INCIDENT
 Cold or hot start up
Get a thorough description of the incident from the customer. It is important for simulating the conditions of the
problem.
Vehicle Vibration
The problem may occur or become worse while drivi ng on a rough road or when engine is vibrating (idle with
A/C on). In such a case, you will want to check for a vi bration related condition. Refer to the following illustra-
tion.
CONNECTORS & HARNESS
Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently
shake each connector and harness while monitoring the sy stem for the incident you are trying to duplicate.
This test may indicate a loose or poor electrical connection.
HINT
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector termi-
nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs inter-
mittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the
terminals on related connectors in the system.
SENSORS & RELAYS
Gently apply a slight vibration to sensors and relays in the system you are inspecting.
This test may indicate a loose or poorly mounted sensor or relay.
ENGINE COMPARTMENT
There are several reasons a vehicle or engine vibration could cause an e\
lectrical complaint. Some of the
things to check for are:
 Connectors not fully seated.
 Wiring harness not long enough and is being stressed due to engine vibrations or rocking.
 Wires laying across brackets or moving components.
 Loose, dirty or corroded ground wires.
 Wires routed too close to hot components.
To inspect components under the hood, start by verifyi ng the integrity of ground connections. (Refer to Ground
Inspection described later.) First check that the system is properly grounded. Then check for loose connection
by gently shaking the wiring or components as previous ly explained. Using the wiring diagrams inspect the
wiring for continuity.
BEHIND THE INSTRUMENT PANEL
An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehi-
cle vibration can aggravate a harness which is routed along a bracket or near a screw.
UNDER SEATING AREAS
An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides)
during vehicle vibration. If the wiring runs under s eating areas, inspect wire routing for possible damage or
pinching.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
If the noise can be duplicated easily during the test drive, to helpidentify the source of the noise, try to dupli-
cate the noise with the vehiclestopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears tobe coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle “twist”.
5) At idle, apply engine load (electrical load, half-cl utch on M/T models, drive position on A/T models).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.
 Drive the vehicle and attempt to duplicate the conditi ons thecustomer states exist when the noise occurs.
 If it is difficult to duplicate the noise, drive the v ehicle slowlyon an undulating or rough road to stress the vehi-
cle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technica lService Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, fo llow the procedure to repair thenoise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1. Narrow down the noise to a general area. To help pi npoint the source of the noise, use a listening tool
(Chassis Ear: J39570, Engine Ear and mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the causeof the noise by:
 removing the components in the area that you suspect the noiseis coming from. Do not use too much force when removing clips and fasteners, otherwiseclips and fastener can be broken or
lost during the repair, resulting in thecreation of new noise.
 tapping or pushing/pulling the component t hat you suspect is causingthe noise.
Do not tap or push/pull the component with excessive force, otherwisethe noise will be eliminated only tem-
porarily.
 feeling for a vibration with your hand by touching t he component(s)that you suspect is (are) causing the
noise.
 placing a piece of paper between components that you suspect arecausing the noise.
 looking for loose components and contact marks. Refer to GW-7, "
Generic Squeak and Rattle Troubleshooting".
REPAIR THE CAUSE
 If the cause is a loose component, tighten the component securely.
 If the cause is insufficient clearance between components:
- separate components by repositioning or l oosening and retighteningthe component, if possible.
- insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane
tape. A Nissan Squeak and Rattle Kit (J43980) is av ailable through your authorized Nissan Parts Depart-
ment.
CAUTION:
Do not use excessive force as many components are constructed of plasticand may be damaged.
NOTE:
Always check with the Parts Departm ent for the latest parts information.
