VALVE LIFTER BORE DIAMETER
Measure the bore diameter of the cylinder head valve lifter with an
inside micrometer.
Standard: 34.495 - 34.515 mm (1.3581 - 1.3589 in) dia.
VALVE LIFTER CLEARANCE CALCULATIONS
Clearance = Valve lifter bore diameter þ Valve lifter outer diameter
Standard: 0.030 - 0.065 mm (0.0012 - 0.0026 in)
If it exceeds the standard value, refer to the outer diameter and
bore diameter standard values and replace valve lifter and/or cyl-
inder head.
Installation
1. Install the valve lifter and adjusting shim.
IMake sure that these are installed in the same position as
before the removal process.
2. Install the camshaft.
IFollow the distinguishing marks that were placed on in the
removal process.
IFace the key in the direction shown in the figure.
3. Install the camshaft bracket.
IRefer to the camshaft bracket upper side journal No. and install.
ILooking from the exhaust manifold side (left side of engine),
install in the direction that the journal number can be read cor-
rectly.
IPlace baffle plate onto upper face of No. 1 camshaft bracket,
and tighten together.
4. Tighten the installation bolts in numerical order in the figure.
1) Tighten to 10 to 14 N×m (1.0 to 1.5 kg-m, 8 to 10 ft-lb).
IMake sure that the thrust portion of the camshaft is fitted prop-
erly in the head installation side.
2) Tighten to 20 to 23 N×m (2.0 to 2.4 kg-m, 15 to 17 ft-lb).

GEAR TRAIN
Camshaft drive gear, injection pump drive gear, oil pump gear,
idler gear, crankshaft gear and vacuum pump gear.
1. If gear tooth and key have scratches or are excessively worn,
replace gear and key.
2. Check gear train backlash before disassembling and after
assembling.
Method A (Using dial gauge)
Method B (Using fuse wire)
If beyond the limit, replace gear.
Backlash:
Standard
0.07 - 0.11 mm (0.0028 - 0.0043 in)
Limit
0.20 mm (0.0079 in)
IDLER GEAR BUSHING CLEARANCE
1. Measure idler gear shaft outer diameter.
2. Measure idler gear bushing inner diameter.
3. Calculate idler gear bushing clearance.
Bushing oil clearance:
Standard
0.025 - 0.061 mm (0.0010 - 0.0024 in)
Limit
0.20 mm (0.0079 in)
IDLER GEAR END PLAY
Measure idler gear end play between gear plate and gear.
Idler gear end play:
Standard
0.03 - 0.14 mm (0.0012 - 0.0055 in)
Limit
Less than 0.3 mm (0.012 in)

6. Before servicing the vehicle, protect fenders, upholstery and
carpeting with appropriate covers.
Take caution that keys, buckles or buttons on your person do
not scratch the paint.
7. Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
8. Replace oil seals, gaskets, packings, O-rings, locking washers,
cotter pins, self-locking nuts, etc. with new ones.
9. Replace inner and outer races of tapered roller bearings and
needle bearings as a set.
10. Arrange the disassembled parts in accordance with their
assembled locations and sequence.
11. Do not touch the terminals of electrical components which use
microcomputers (such as electronic control units).
Static electricity may damage internal electronic components.
12. After disconnecting vacuum or air hoses, attach a tag to indi-
cate the proper connection.
13. Use only the lubricants specified in MA section.
14. Use approved bonding agent, sealants or their equivalents
when required.
15. Use tools and recommended special tools where specified for
safe and efficient service repairs.
16. When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.
17. Dispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.
Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
(Dual Air Bag System)
The Supplemental Restraint System ªAir Bagº and ªSeat Belt Pre-
tensionerº, used along with a seat belt, help to reduce the risk or
severity of injury to the driver and front passenger in a frontal col-
lision. The Supplemental Restraint System consists of air bag mod-
ules (located in the center of the steering wheel and on the instru-
ment panel on the passenger side), seat belt pre-tensioners, a
diagnosis sensor unit, warning lamp, wiring harness and spiral
cable.
WARNING:
ITo avoid rendering the SRS inoperative, which could
increase the risk of personal injury or death (in the event
of a collision which would result in air bag inflation), all
maintenance must be performed by an authorized NISSAN
dealer.
IImproper maintenance, including incorrect removal and
installation of the SRS, can lead to personal injury caused
by unintentional activation of the system.
IDo not use electrical test equipment on any circuit related
to the SRS unless instructed to do so in this Service
Manual. SRS wiring harnesses are covered with yellow

insulation (either just before the harness connectors or for
the complete harness), for easy identification.
Precautions for NATS
NATS (Nissan Anti-Theft System)
NATS will immobilize the engine if someone tries to start it without
the registered key of NATS.
Both of the originally supplied ignition key IDs have been NATS
registered.
The NATS security indicator is located on the instrument panel. The
indicator blinks when the ignition switch is in ªOFFº or ªACCº posi-
tion. Therefore, NATS warns outsiders that the vehicle is equipped
with the anti-theft system.
IWhen NATS detects trouble, the malfunction indicator lamp
(MIL) blinks.
This blinking indicates that the anti-theft is not functioning, so
prompt service is required.
IIf the malfunction indicator lamp comes on while the engine is
running, return the vehicle to the workshop before turning the
ignition switch ªOFFº.
Once the ignition switch is turned ªOFFº, the engine can not be
started.
IWhen servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs) CON-
SULT-II hardware and CONSULT-II NATS software is neces-
sary.
Regarding the procedures of NATS initialization and NATS igni-
tion key ID registration, refer to CONSULT-II operation manual,
NATS.
Therefore, CONSULT-II NATS software (program card and
operation manual) must be kept strictly confidential to main-
tain the integrity of the anti-theft function.
IWhen servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs), it
may be necessary to re-register original key identification.
Therefore, be sure to receive all keys from vehicle owner.
A maximum of five key IDs can be registered into NATS.
IWhen failing to start the engine first-time using the key of
NATS, starts as follows:
(1) Turn ignition key to ªOFFº.
(2) Wait approx. 5 seconds.
(3) Turn ignition key to ªSTARTº again while keeping the key
apart from any others on key-chain.

Work Flow
STEP DESCRIPTION
STEP 1 Get detailed information about the conditions and the environment when the incident occurred.
The following are key pieces of information required to make a good analysis:
WHATVehicle Model, Engine, Transmission and the System (i.e. Radio).
WHENDate, Time of Day, Weather Conditions, Frequency.
WHERERoad Conditions, Altitude and Traffic Situation.
HOWSystem Symptoms, Operating Conditions (Other Components Interaction).
Service History and if any After Market Accessories have been installed.
STEP 2 Operate the system, road test if necessary.
Verify the parameter of the incident.
If the problem cannot be duplicated, refer to ªIncident Simulation Testsº next page.
STEP 3 Get the proper diagnosis materials together including:
POWER SUPPLY ROUTING
System Operation Descriptions
Applicable Service Manual Sections
Check for any Service Bulletin.
Identify where to begin diagnosis based upon your knowledge of the system operation and the customer comments.
STEP 4 Inspect the system for mechanical binding, loose connectors or wiring damage.
Determine which circuits and components are involved and diagnose using the Power Supply Routing and Harness
Layouts.
STEP 5 Repair or replace the incident circuit or component.
STEP 6 Operate the system in all modes. Verify the system works properly under all conditions. Make sure you have not inad-
vertently created a new incident during your diagnosis or repair steps.
