Removal and InstallationEBS011TI
REMOVAL
1. Open oil filter installation/removal cover on RH undercover.
2. Using an oil filter wrench (special service tool), remove oil filter.
CAUTION:

Oil filter is provided with relief valve. Use Genuine NIS-
SAN Oil Filter or equivalent.

Be careful not to get burned when engine and engine oil
may be hot.

engine oil leakage or spillage.

Do not allow engine oil to adhere to drive belt.

Completely wipe off any engine oil that adheres to engine
and vehicle.
INSTALLATION
1. Remove foreign materials adhering to the oil filter installation surface.
2. Apply new engine oil to the oil seal contact surface of new oil fil-
ter.
3. Screw oil filter manually until it touches the installation surface,
then tighten it by 2/3 turn. Or tighten to specification.
INSPECTION AFTER INSTALLATION
1. Start engine, and make sure there is no leaks of engine oil.
2. Stop engine and wait for 10 minutes.
3. Check the engine oil level and adjust engine oil. Refer to LU-7, "
ENGINE OIL" .

WARNING:
Be careful not to get burned when engine and engine oil may be hot.
CAUTION:

When removing oil cooler and oil cooler bracket, prepare a shop cloth to absorb any engine oil
leakage or spillage.

Completely wipe off any engine oil that adhere to engine and vehicle.
REMOVAL
1. Remove RH front road wheel and tyre and RH undercover.
2. Drain engine coolant by removing water drain plug on cylinder block and radiator drain plug. Refer to EM-
89, "CYLINDER BLOCK" and CO-9, "Changing Engine Coolant" .
3. Disconnect water hoses from oil cooler.
4. Remove oil cooler and oil cooler bracket.
NOTE:
For reference when installing, put a mating mark on oil cooler and oil cooler bracket.
INSPECTION AFTER REMOVAL
Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing through engine coolant inlet. If necessary,
replace oil cooler assembly.
Relief Valve
Inspect relief valve for movement, cracks and breaks by pushing the ball. If replacement is necessary, remove
valve by prying it out with a suitable tool. Install a new valve in place by tapping it.
INSTALLATION
Installation is the reverse order of removal.
INSPECTION AFTER INSTALLATION
1. Check the engine oil level and the engine coolant level, and adjust engine oil and engine coolant. Refer to
LU-7, "
ENGINE OIL" and CO-9, "ENGINE COOLANT" .

INSPECTION AFTER DISASSEMBLY
Clearance of Oil Pump Parts

Measure the clearance with feeler gauge.
–Clearance between outer rotor and front cover (Position “1”)
–If out of the standard, replace oil pump assembly.
–Tip clearance between inner rotor and outer rotor (Position “2”)
–If out of the standard, replace inner rotor and outer rotor.

Measure the clearance with feeler gauge and straightedge.
–Side clearance between inner rotor and front cover (Position “3”)
–If out of the standard, replace oil pump assembly.
–Side clearance between outer rotor and front cover (Position “4”)
–If out of the standard, replace oil pump assembly.

Calculate the clearance between inner rotor and front cover with
the following procedure:
–Measure the outer diameter of protruded portion of inner rotor
with micrometer. (Position “5”)
–Measure the inner diameter of front cover with inside microme-
ter. (Position “6”)
–(Clearance) = (Inner diameter of front cover) – (Outer diameter of inner rotor)
–If out of the standard, replace oil pump assembly.Standard : 0.114 - 0.179 mm (0.0045 - 0.0070 in)

Make sure that it falls smoothly into valve hole by its own
weight.
ASSEMBLY
Note the following, and assemble in the reverse order of disassembly.

Precautions for Liquid GasketEBS011SZ
LIQUID GASKET APPLICATION PROCEDURE
1. Remove the old liquid gasket adhering to the gasket application surface and the mating surface.

Remove the liquid gasket completely from the gasket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to the tube presser (special service
tool).
Use Genuine Liquid Gasket or equivalent.

Within five minutes of gasket application, install the mating com-
ponent.

If the liquid gasket protrudes, wipe it off immediately.

Do not retighten mounting bolts and nuts after the installation.

Wait 30 minutes or more after installation before filling the
engine with engine oil and engine coolant.
