Oil Pressure Check
NHLC0004
WARNING:
I
Be careful not to burn yourself, as the engine and oil may
be hot.
I
Oil pressure check should be done in “Parking position”.

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.

OIL PUMP INSPECTION
NHLC0007
Using a feeler gauge, straightedge and micrometers, check the
following clearances:
Unit: mm (in)
Body to outer rotor radial clearance 1
0.114 - 0.200 (0.0045 - 0.0079)
Inner rotor to outer rotor tip clearance
2
Below 0.18 (0.0071)
Body to inner rotor axial clearance 3
0.030 - 0.070 (0.0012 - 0.0028)
Body to outer rotor axial clearance 4
0.050 - 0.110 (0.0020 - 0.0043)
Inner rotor to brazed portion of hous-
ing clearance 5
0.045 - 0.091 (0.0018 - 0.0036)
I
If the tip clearance (2) exceeds the limit, replace rotor set.
I
If body to rotor clearances (1, 3, 4, 5) exceed the limit,
replace oil pump body assembly.

REGULATOR VALVE INSPECTION
NHLC0008
1.
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 oil pump body.
SLC935AA
4.
Check regulator valve to oil pump body clearance.
Clearance:
6 : 0.040 - 0.097 mm (0.0016 - 0.0038 in)
If it exceeds the limit, replace oil pump body.
SLC035B
OIL FILTER
NHLC0009
The oil filter is a small, full-flow cartridge type and is provided with
a relief valve.
I
Use Tool specified in MA-18 for changing oil filter.

Precautions
LIQUID GASKET APPLICATION PROCEDURE
NHLC0013
1.
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 RTV silicone sealant Part No. 999MP-A7007
or equivalent.)
I
For areas except oil pan, be sure liquid gasket diameter is 2.3
to 3.3 mm (0.091 to 0.130 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.
