OIL PUMP INSPECTIONNJLC0045+Install the inner rotor and outer rotor with the punched
marks on the pump cover side.
Using a feeler gauge, straightedge and micrometers, check the
following clearances:
Unit: mm (in)
Body to outer rotor radial clearance10.114 - 0.260 (0.0045 - 0.0102)
Inner rotor to outer rotor tip clearance
2Below 0.18 (0.0071)
Body to inner rotor axial clearance30.050 - 0.090 (0.0020 - 0.0035)
Body to outer rotor axial clearance40.030 - 0.190 (0.0012 - 0.0075)
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 oil pump body assembly.

REGULATOR VALVE INSPECTIONNJLC00461. 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.

Changing Engine OilNJLC0074WARNING:
+Be careful not to burn yourself, as the engine oil is hot.
+Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com-
ponents.
2. Stop engine and wait more than 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain oil and refill with new engine oil.
Oil Specification and Viscosity:
+API grade CF-4
Refer to MA-16, ªRECOMMENDED FLUIDS AND LUBRI-
CANTSº.

CAUTION:
+Be sure to clean drain plug and install with new washer.
Drain plug:
: 29 - 39 N´m (3.0 - 4.0 kg-m, 22 - 29 ft-lb)
+The refill capacity depends on the oil temperature and
drain time. Use these specifications for reference only.
Always use the dipstick to determine when the proper
amount of oil is in the engine.
5. Check oil level.
6. Start engine and check area around drain plug and oil filter for
oil leakage.
7. Run engine for a few minutes, then turn it off. After several
minutes, check oil level.

2. Drain the oil after matching the ªDRAINº arrow mark at the
bottom of the filter body to the protrusion on the oil filter
bracket.
+Catch the oil with a pan or cloth.
CAUTION:
+The drained oil flows over the right surface of the filter
body.
+Completely wipe clean any engine oil remaining on the
filter body or vehicle.
3. Remove the filter body, then remove the oil filter element.
JLC292B
4. Remove the O-ring from the filter body.
+Push the O-ring in one direction, lift the slack part using
fingers, and remove the O-ring from the filter body.
CAUTION:
Do not use wires or flat-bladed screwdrivers etc. as they may
cause damage to the filter body.
INSTALLATIONNJLC0076S021. Completely remove all foreign objects adhering to the inside of
the filter body or O-ring mounting area (body side and bracket
side).
2. Install the oil filter element and O-ring to the filter body.
+Push the oil filter element into the filter body completely.
3. Install the filter body to the oil filter bracket.
: 20 - 24 N´m (2.0 - 2.5 kg-m, 15 - 18 ft-lb)
4. After warming up the engine, check for engine oil leakage.

Precautions
LIQUID GASKET APPLICATION PROCEDURENJLC00511. 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.)
+For oil pan, be sure liquid gasket diameter is 4.0 to 5.0 mm
(0.157 to 0.197 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.
