8. Use a depth gauge to measure the distance between the mount-
ing surface of the cylinder head spring seat and the valve stem
end. If the distance is shorter than specified, repeat step 5
above to adjust it. If it is longer, replace the valve seat with a
new one.

boot to shaft. Be careful not to damage boot.
CAUTION:
Discard the old boot band and boot: replace with new ones.
2. Remove protective tape wound around serrated part of shaft.
3. Line up alignment marks which were made when spider assem-
bly was removed. Install spider assembly, with serration chamfer
facing drive shaft.
4. Secure spider assembly with snap ring.
CAUTION:
Discard the old snap ring: replace with new ones.
5. Apply Nissan genuine grease or equivalent to spider assembly
and sliding surface.
6. Install sliding joint housing to spider assembly. Add remaining
grease up to the amount listed below.
7. Install boot securely into grooves (indicated by * marks) shown
in the figure.
CAUTION:
If there is grease on boot mounting surfaces (indicated by *
marks) of joint, boot may come off. Remove all grease from
surfaces.
8. Check that boot installation length “L” is the length indicated
below. Insert a screwdriver or similar tool into smaller side of
boot. Remove air from boot to prevent boot deformation.
CAUTION:
lBoot may break if boot installation length is less than
standard value.
lBe careful that screwdriver tip does not contact inside
surface of boot.

PRECAUTIONS
Precautions for Multiport Fuel Injection System or Engine Control System
EAS000FT
lBefore connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
lBefore disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
lBe careful not to jar components such as ECM and mass air
flow sensor.
Precautions for Turbocharger (If Equipped)EAS000FU
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean sup-
ply of oil flowing through the turbocharger and to follow all required
maintenance instructions and operating procedures.
lAlways use the recommended oil. Follow the instructions for
proper time to change the oil and proper oil level.
lAvoid accelerating engine to a high rpm immediately after start-
ing.
lIf engine had been operating at high rpm for an extended period
of time, let it idle for a few minutes prior to shutting if off.
Precautions for HosesEAS000FV
HOSE REMOVAL AND INSTALLATION
lTo prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.
lTo reinstall the rubber hose securely, make sure that hose inser-
tion length and orientation is correct. (If tube is equipped with
hose stopper, insert rubber hose into tube until it butts up
against hose stopper.)
