EM-105

SEM085D
+Always use new valve oil seal.
Refer to EM-105.
+Before installing valve oil seal, install valve spring seat.
+Install valve spring (uneven pitch type) with its narrow
pitched side (paint mark) toward cylinder head side.
+After installing valve components, use plastic hammer to
lightly tap valve stem tip to assure a proper fit.

2. Check hydraulic lash adjusters.
a. Push on the rocker arm above the hydraulic lash adjuster. If it
moves 1 mm (0.04 in) or more, there is air in the high pressure
chamber of hydraulic lash adjuster.
Noise will be emitted from hydraulic lash adjuster if engine is
started without bleeding air.
AEM117
b. Remove hydraulic lash adjuster and dip in a container filled
with new engine oil. While pushing plunger as shown in figure,
lightly push check ball using a thin rod. Air is completely bled
when plunger no longer moves.
Air cannot be bled from this type of lash adjuster by running
engine.

Trouble Diagnosis of Turbocharger=NLEM0104S0206Preliminary check:
+Check that the engine oil level is between MIN and MAX of the
dipstick. (When the engine oil amount is more than MAX, the
oil flows into the inlet duct through the blow-by gas passage,
and the turbocharger is misjudged failure.)
+Ask the customer if he/she always runs the vehicle in idle
engine speed to cool the oil down after driving.
+Replace the turbocharger assembly when any malfunction is
found after unit inspections specified in the table below.
+If no malfunction is found after the unit inspections, judge that
the turbocharger body has no failure. Check the other parts
again.

Precautions for Service EquipmentNLHA0117RECOVERY/RECYCLING EQUIPMENTNLHA0117S01Follow the manufacturer’s instructions for machine operation and
machine maintenance. Never introduce any refrigerant other than
that specified into the machine.
ELECTRONIC LEAK DETECTORNLHA0117S02Follow the manufacture’s instructions for tester operation and
tester maintenance.
RHA270D
VACUUM PUMPNLHA0117S03The lubricant contained inside the vacuum pump is not compatible
with the specified lubricant for HFC-134a (R-134a) A/C systems.
The vent side of the vacuum pump is exposed to atmospheric
pressure. So the vacuum pump lubricant may migrate out of the
pump into the service hose. This is possible when the pump is
switched off after evacuation (vacuuming) and hose is connected
to it.
To prevent this migration, use a manual valve situated near the
hose-to-pump connection, as follows.
+Usually vacuum pumps have a manual isolator valve as part
of the pump. Close this valve to isolate the service hose from
the pump.
+For pumps without an isolator, use a hose equipped with a
manual shut-off valve near the pump end. Close the valve to
isolate the hose from the pump.
+If the hose has an automatic shut off valve, disconnect the
hose from the pump: as long as the hose is connected, the
valve is open and lubricating oil may migrate.
Some one-way valves open when vacuum is applied and close
under a no vacuum condition. Such valves may restrict the pump’s
ability to pull a deep vacuum and are not recommended.
SHA533D
MANIFOLD GAUGE SETNLHA0117S04Be certain that the gauge face indicates R-134a or 134a. Make
sure the gauge set has 1/2″-16 ACME threaded connections for
service hoses. Confirm the set has been used only with refrigerant
HFC-134a (R-134a) along with specified lubricant.
RHA272D
SERVICE HOSESNLHA0117S05Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive
shut off devices (either manual or automatic) near the end of the
hoses opposite the manifold gauge.
