2. Check diameter of valve lifter and valve lifter guide bore.
Valve lifter outer diameter:
29.960 - 29.975 mm (1.1795 - 1.1801 in)
SEM867E
Lifter guide bore diameter:
30.000 - 30.021 mm (1.1811 - 1.1819 in)

AssemblyNJEM00661. Install valve oil seal.
+Using valve oil seal drift (SST), install so that the dimension
shown in the figure is obtained. The dimension in the figure
shows the dimension before the valve spring seat is installed.
+Different parts should be used depending on the valve oil seal
location. Identify by the rubber color.
For intake: Black
For exhaust: Brown
+Always use new valve oil seal.
+Before installing valve oil seal, install valve spring seat.
2. Install other valve component parts. Refer to ªDisassemblyº,
EM-121.
+For uneven pitch type models only, install valve spring
with its narrow pitch side toward cylinder head side (paint
mark).
+After installing valve collets, tap valve stem tip with plastic
hammer to assure a proper fit.
InstallationNJEM0067+Before installation, remove old liquid gasket from mating
surface of all liquid gasket applied parts.

+Do not use gasoline, kerosine, diesel fuel, gas oil, thinners or
solvents for cleaning skin.
+If skin disorders develop, obtain medical advice without delay.
+Where practicable, degrease components prior to handling.
+Where there is a risk of eye contact, eye protection should be
worn, for example, chemical goggles or face shields; in addi-
tion an eye wash facility should be provided.
Environmental Protection PrecautionsNJGI0001S0702Burning used engine oil in small space heaters or boilers can be
recommended only for units of approved design. The heating sys-
tem must meet the requirements of HM Inspectorate of Pollution for
small burners of less than 0.4 MW. If in doubt, check with the
appropriate local authority and/or manufacturer of the approved
appliance.
Dispose of used oil and used oil filters through authorized waste
disposal contractors to licensed waste disposal sites, or to the
waste oil reclamation trade. If in doubt, contact the local authority
for advice on disposal facilities.
It is illegal to pour used oil on to the ground, down sewers or drains,
or into water courses.
The regulations concerning the pollution vary between
regions.
PRECAUTIONS FOR FUELNJGI0001S08Gasoline EngineNJGI0001S0803Models with three way catalyst
Unleaded premium gasoline of at least 95 octane (RON)
If premium gasoline is not available, unleaded regular gaso-
line with an octane rating of 91 (RON) may be temporarily
used, but only under the following precautions:
+Have the fuel tank filled only partially with unleaded regu-
lar gasoline, and fill up with premium unleaded gasoline
as soon as possible.
+Avoid full throttle driving and abrupt acceleration.
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will dam-
age the three way catalyst.
Diesel Engine*:NJGI0001S0804Diesel fuel of at least 50 cetane
* If two types of diesel fuel are available, use summer or winter
fuel properly according to the following temperature conditions.
+Above þ7ÉC (20ÉF) ... Summer type diesel fuel.
+Below þ7ÉC (20ÉF) ... Winter type diesel fuel.
CAUTION:
+Do not use home heating oil, gasoline, or other alternate
fuels in your diesel engine. The use of those can cause
engine damage.
+Do not use summer fuel at temperatures below þ7ÉC
(20ÉF). The cold temperatures will cause wax to form in the
fuel. As a result, it may prevent the engine from running
smoothly.
+Do not add gasoline or other alternate fuels to diesel fuel.
PRECAUTIONS FOR AIR CONDITIONINGNJGI0001S09Use an approved refrigerant recovery unit any time the air condi-
tioning system must be discharged. Refer to HA-78, ªHFC-134a
(R-134a) Service Procedureº for specific instructions.
PRECAUTIONS
Precautions (Cont'd)
GI-8

+Do not store or heat refrigerant containers above 52ÉC (125ÉF).
+Do not heat a refrigerant container with an open flame; if container warming is required, place the
bottom of the container in a warm pail of water.
+Do not intentionally drop, puncture, or incinerate refrigerant containers.
+Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.
+Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent
suffocation.
+Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condi-
tioning systems with compressed air during repair. Some mixtures of air and R-134a have been
shown to be combustible at elevated pressures. These mixtures, if ignited, may cause injury or
property damage. Additional health and safety information may be obtained from refrigerant manu-
facturers.
Precautions for Refrigerant ConnectionNJHA0115A new type refrigerant connection has been introduced to all refrigerant lines except the following portion.
+Expansion valve to cooling unit
FEATURES OF NEW TYPE REFRIGERANT CONNECTIONNJHA0115S01+The O-ring has been relocated. It has also been provided with a groove for proper installation. This elimi-
nates the chance of the O-ring being caught in, or damaged by, the mating part. The sealing direction of
the O-ring is now set vertically in relation to the contacting surface of the mating part to improve sealing
characteristics.
+The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby
facilitating piping connections.

General Refrigerant Precautions (Cont'd)
HA-3

+When installing an air conditioner in the vehicle, connect the pipes as the final stage of the opera-
tion. Do not remove the seal caps of pipes and other components until just before required for
connection.
+Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
+Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
+Always replace used O-rings.
+When connecting tube, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.
Lubricant name: Nissan A/C System Oil Type R for DKV-11G compressor
Part number: KLH00-PAGR0
Lubricant name: Nissan A/C System Oil Type S for CSV613 compressor
Part number: KLH00-PAGS0
+O-ring must be closely attached to dented portion of tube.
+When replacing the O-ring, be careful not to damage O-ring and tube.
+Connect tube until you hear it click, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.
+After connecting line, conduct leak test and make sure that there is no leakage from connections.
When the gas leaking point is found, disconnect that line and replace the O-ring. Then tighten
connections of seal seat to the specified torque.
RHA861F
Precautions for Servicing CompressorNJHA0116+Plug all openings to prevent moisture and foreign matter from entering.
+When the compressor is removed, store it in the same position as it is when mounted on the car.
+When replacing or repairing compressor, follow ªMaintenance of Lubricant Quantity in Compres-
sorº exactly. Refer to HA-80.
+Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with
lubricant, wipe it off by using a clean waste cloth moistened with thinner.
+After compressor service operation, turn the compressor shaft by hand more than five turns in
both directions. This will equally distribute lubricant inside the compressor. After the compressor
is installed, let the engine idle and operate the compressor for one hour.
+After replacing the compressor magnet clutch, apply voltage to the new one and check for normal
operation.

Maintenance of Lubricant Quantity in
Compressor
NJHA0160The lubricant in the compressor circulates through the system with
the refrigerant. Add lubricant to compressor when replacing any
component or after a large gas leakage occurred. It is important to
maintain the specified amount.
If lubricant quantity is not maintained properly, the following mal-
functions may result:
+Lack of lubricant: May lead to a seized compressor
+Excessive lubricant: Inadequate cooling (thermal exchange
interference)
