OUTPUT RODLENGTH CHECK

1. Supply brakebooster withvacuum of-66.7 kPa(-667 mbar,
-500 mmHg, -19.69inHg)usingahand vacuum pump.
2. Check output rodlength.
Specified length:
M195, S205orC205
10.275 -10.525 mm(0.4045 -0.4144 in)
Installation
CAUTION: • Becareful nottodeform orbend brake pipesduring instal-
lation ofbooster.
• Replace clevispinifdamaged.
• Refill withnewbrake fluid"DOT 3"or"DOT 4".
• Never reusedrained brakefluid.
• Donol mix different typesofbrake fluids(DOT3,DOT 4).
• Due tothe angle ofinstallation, threadcanbedamaged by
the dash panel.
1. Before fittingbooster, temporarily adjustclevistodimen-
sion shown. (Doesnotapply tovehicles fittedwithABS.)
2. Fitbooster, thensecure mounting nuts(brake pedalbracket
to booster) lightly.
3. Connect brakepedalandbooster inputrodwith clevis pin.
4. Secure mounting nuts.

RUNOUT
1: Secure rotortowheel hubwith atleast twonuts (M12 x
1.25).
2. Check runout usingadial indicator.

Make surethatwheel bearing axialendplay iswithin thespec-
ifications beforemeasuring. RefertoFA section ("FrontWheel
Bearing", "ON-VEHICLE SERVICE").
Maximum runout:
SBR936A 0.07mm(0.0028 in)

3.
If
the runout isout ofspecification, findminimum runout
position asfollows:
a. Remove nutsandrotor fromwheel hub.
b. Shift therotor onehole andsecure rotortowheel hub
with nuts.
c. Measure runout.
d. Repeat stepsa.to c.so that minimum runoutposition can
be found.
4. Ifthe runout isstill outofspecification, turnrotor withon-car
brake lathe("MAD, DL-8700", "AMMCO700and 705" or•••
equivalent).

Precautions forECCS Trouble Diagnosis of
Engine

CAUTION:
• Besure toturn theignition switch"OFF" anddisconnect thenegative batteryterminal beforeany
repair orinspection work.Theopen/short circuitofrelated switches, sensors,solenoidvalves,etc.
will cause malfunction.
• Besure toconnect andlock theconnectors securelyafterwork. Aloose (unlocked) connectorwill
cause malfunction duetothe open circuit. (Besure theconnector isfree from water, grease, dirt,
bent terminals, etc.)
• Besure toroute andclamp theharnesses properlyafterwork. Theinterference ofthe harness with
a bracket, etc.may cause malfunction duetothe short circuit.
• Besure toconnect rubbertubesproperly afterwork. Amisconnected ordisconnected rubbertube•
may cause malfunction.
• Besure toerase theunnecessary malfunctioninformation(repairscompleted) inthe ECM before
returning thevehicle tothe customer.

Precautions

• Before connecting ordisconnecting theECM harness
connector, turnignition switchOFFanddisconnect negative
battery terminal. Failuretodo somay damage theECM
because batteryvoltage isapplied toECM even ifignition
switch isturned off.

SEF289H
•When connecting ECMharness connector, tightensecuring
bolt until redprojection isin line with connector face.

SEF725H
•When connecting ordisconnecting pinconnectors intoor
from ECM, takecare nottodamage pinterminals (bendor
break). Make surethatthere arenotany bends orbreaks onECM
pin terminal, whenconnecting pinconnectors.

Install crankshaft andmain bearing capsandtighten bolts
to the specified torque.

• Apply newengine oiltobolt threads andseat surface.
• Prior totightening bearingcapbolts, placebearing capin
its proper position byshifting crankshaft inthe axial direc-
tion.
• Tighten bearing capbolts gradually intwo orthree stages.
Start withcenter bearing andmove outward sequentially.
• After securing bearingcapbolts, makesurecrankshaft
turns smoothly byhand.

3. Measure crankshaft endplay.

Crankshaft endplay:
Standard:
0.060 -0.180 mm(0.0024 -0.0071 in)
Limit: 0.3 mm (0.012 in)
If beyond thelimit, replace thrustbearing witha

new one.

4. Install connecting rodbearings inconnecting rodsandcon-
necting rodcaps.

• Confirm thatcorrect bearings areused. Referto
"Inspection" (EM-52).
• Install bearings sothat oilhole inconnecting rodaligns with
oil hole ofbearing.
• Apply engine oiltobolt threads andbearing surfaces.

5. Install pistons withconnecting rods.
a. Install themintocorresponding cylinderswithTool.

• Becareful nottoscratch cylinder wallbyconnecting rod.
• Arrange sothat front mark onpiston headfaces toward

Precautions forNATS V2.0(ForGasoline Engine
Model)
NATS (Nissan Anti-Theft System)

NATS V2.0willimmobilize theengine ifsomeone triestostart
it without theregistered keyofNATS V2.0.
Both ofthe originally suppliedignitionkeyIDshave been NATS
registered.
The NATS security indicator islocated onthe instrument panel.
The indicator blinkswhentheignition switchisin "OFF" or
"ACC" position. Therefore, NATSwarns outsiders thatthevehi-
cle isequipped withtheanti-theft system.
• When NATSdetects trouble, themalfunction indicatorlamp
(MIL) blinks.
This blinking indicates thattheanti-theft isnot functioning,
so prompt service isrequired.
• When servicing NATS(trouble diagnoses, systeminitialisa-
tion andadditional registration ofother NATS ignition key
IDs), CONSULT hardwareandCONSULT NATSsoftware is
necessary.
Regarding theprocedures ofNATS initialisation andNATS
ignition key
10
registration, refertoCONSULT operation
manual, NATSV2.0.

Therefore, CONSULTNATSsoftware (program cardandoper-
ation manual) mustbekept strictly confidential tomaintain the
integrity ofthe anti-theft function.

• When servicing NATSV2.0(trouble diagnoses, systemini-
tial isation andadditional registration ofother NATS ignition
key IDs),
it
may benecessary tore-register originalkey
identification. Therefore,besure toreceive allkeys from
vehicle owner.
A maximum offour keyIDscan beregistered intoNATS.
• When failing tostart theengine first-time usingthekey of
NATS V2.0,startasfollows.
(1) Turn ignition keyto"OFF".
(2) Wait approx. 5seconds.
(3) Turn ignition keyto"START" againwhilekeeping the
key apart fromanyothers onkey-chain.

SGI285 General
Precautions

• Donot operate theengine foranextended periodoftime
without properexhaust ventilation.
Keep thework areawellventilated andfree ofany flamma-
ble materials. Specialcareshould betaken whenhandling
any flammable orpoisonous materials,suchasgasoline,
refrigerant gas,etc.When working inapit orother enclosed
area, besure toproperly ventilate thearea before working
with hazardous materials.
Do not smoke whileworking onthe vehicle.
