Refrigeration System
REFRIGERATION CYCLENLHA0121Refrigerant FlowNLHA0121S01The refrigerant flows in the standard pattern, that is, through the compressor, the condenser, the liquid tank,
through the evaporator, and back to the compressor. The refrigerant evaporation through the evaporator coil
is controlled by an externally equalized expansion valve, located inside the heater & cooling unit.
Freeze ProtectionNLHA0121S02The compressor cycles go on and off to maintain the evaporator temperature within a specified range. When
the evaporator coil temperature falls below a specified point, the thermo control amplifier interrupts the com-
pressor operation. When the evaporator coil temperature rises above the specification, the thermo control
amplifier allows compressor operation.
Refrigerant System ProtectionNLHA0121S03Refrigerant Pressure SensorNLHA0121S0303The refrigerant system is protected against excessively high or low pressures by the refrigerant pressure
sensor, located on the liquid tank. If the system pressure rises above, or falls below the specifications, the
refrigerant pressure sensor detects the pressure inside the refrigerant line and sends the voltage signal to the
ECM. ECM makes the A/C relay go OFF and stops the compressor when pressure on the high pressure side
detected by refrigerant pressure sensor is over about 2,746 kPa (27.5 bar, 28 kg/cm
2, 398 psi) or below about
137 kPa (1.37 bar, 1.4 kg/cm2, 20 psi).
Dual-pressure Switch
NLHA0121S0304The refrigerant system is protected against excessively high or low pressures by the dual-pressure switch,
located on the liquid tank. If the pressure falls out of specifications, the switch opens to interrupt compressor
operation.
Pressure Relief Valve
NLHA0121S0302The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compres-
sor. When the pressure of refrigerant in the system increases to an abnormal level [more than 3,727 kPa (37.3
bar, 38 kg/cm
2, 540 psi)], the release port on the pressure relief valve automatically opens and releases
refrigerant into the atmosphere.

Precautions
LIQUID GASKET APPLICATION PROCEDURENLLC00011. Use a scraper to remove all traces of old liquid gasket from
mating surfaces and grooves. Also, completely clean any oil
from these areas.
2. Apply a continuous bead of liquid gasket to mating surfaces.
(Use Genuine Liquid Gasket or equivalent.)
+For oil pan, be sure liquid gasket diameter is 3.5 to 4.5 mm
(0.138 to 0.177 in).
+For areas except oil pan, be sure liquid gasket diameter is 2.0
to 3.0 mm (0.079 to 0.118 in).
3. Apply liquid gasket around the inner side of bolt holes (unless
otherwise specified).
4. Assembly should be done within 5 minutes after coating.
5. Wait at least 30 minutes before refilling engine oil and engine
coolant.

Oil Pressure CheckNLLC0004WARNING:
+Be careful not to burn yourself, as the engine and oil may
be hot.
+For M/T models, put gearshift lever in Neutral ªNº posi-
tion.
1. Check oil level.
2. Remove oil pressure switch.
SLC926-A
3. Install pressure gauge.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load.
Engine speed
rpmApproximate discharge pressure
kPa (bar, kg/cm2, psi)
600 More than 98 (0.98, 1.0, 14)
2,000 More than 294 (2.94, 3.0, 43)
6,000 More than 392 (3.92, 4.0, 57)
+If difference is extreme, check oil passage and oil pump
for oil leaks.
6. Install oil pressure switch with sealant.

REMOVAL AND INSTALLATIONNLLC0005+Make sure that O-ring is fitted properly.
1. Drain engine oil.
2. Remove drive belts.
3. Remove oil pan. Refer to EM-20, ªOIL PANº.
4. Remove oil strainer.
5. Remove front cover. Refer to EM-22, ªTIMING CHAINº.

INSPECTIONNLLC0007Using a feeler gauge, check the following clearances.
Standard clearance:
Unit: mm (in)
Body to outer rotor radial clearance10.250 - 0.325 (0.0098 - 0.0128)
Inner rotor to outer rotor tip clearance
2Below 0.18 (0.0071)
Body to inner rotor clearance30.030 - 0.085 (0.0012 - 0.0033)
Body to outer rotor axial clearance40.030 - 0.090 (0.0012 - 0.0035)
Inner rotor to brazed portion of hous-
ing clearance50.045 - 0.091 (0.0018 - 0.0036)

+If the tip clearance (2) exceeds the limit, replace rotor set.
+If body to rotor clearances (1, 3, 4, 5) exceed the limit,
replace front cover assembly.

REGULATOR VALVE INSPECTIONNLLC00081. Visually inspect components for wear and damage.
2. Check oil pressure regulator valve sliding surface and valve
spring.
3. Coat regulator valve with engine oil.
Check that it falls smoothly into the valve hole by its own
weight.
If damaged, replace regulator valve set or front cover assem-
bly.
