●Measure clearance with feeler gauge and straightedge.
Side clearance between inner rotor and oil pump body (position
3).
Side clearance between outer rotor and oil pump body (position
4).
●Calculate the clearance between inner rotor and oil pump body
as follows.
1. Measure the outer diameter of protruded portion of inner rotor
(Position 5).
2. Measure the inner diameter of oil pump body with inside
micrometer (Position 6).
(Clearance) = (Inner diameter of oil pump body) – (Outer diame-
ter of inner rotor)
Regulator Valve Clearance
(Clearance) = D1 (Valve hole diameter) – D2 (Outer diameter of
valve)
CAUTION:
●Coat regulator valve with engine oil.
●Check that it falls smoothly into the valve hole by its own
weight.Standard: 0.030 - 0.070 mm (0.0012 - 0.0028 in)

WARNING:
Be careful not to get burned when the engine and engine oil are hot.
CAUTION:
●When removing oil cooler, prepare a shop cloth to absorb any engine oil leakage or spillage.
●Completely wipe off any engine oil that adhere to the engine and the vehicle.
REMOVAL
1. Remove front RH wheel and engine room right side cover.
2. Drain engine coolant by removing cylinder block drain plug and radiator drain cock. Refer to CO-9,
"Changing Engine Coolant" .
3. Paint a mating mark at the oil cooler and oil cooler bracket.
INSPECTION
Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing through engine coolant inlet. If necessary,
replace oil cooler assembly.
Oil Pressure Relief Valve
Inspect oil pressure relief valve for movement, cracks and breaks by pushing the ball. If replacement is neces-
sary, remove valve by prying it out with a suitable tool. Install a new valve in place by tapping it.
INSTALLATION
Installation is in the reverse order of removal.
●After warming up the engine, check for engine oil and engine coolant leakage and for engine oil level.
Refer to LU-7, "
ENGINE OIL" .

ENGINE OIL LEVEL AND MUDDINESS
●Before starting the engine, put vehicle horizontally then check
the engine oil level. If the engine is already started, stop it and
allow 10 minutes before checking.
●Check that the engine oil level is within the range shown in the
figure.
●If it is out of range, adjust it.
●Check the engine oil for white turbidity or remarkable contamina-
tion.
●If the engine oil becomes turbid and white, it is highly probable
that it is contaminated with engine coolant. Find the cause and
repair.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following area.
●Oil pan
●Oil pan drain plug
●Oil pressure switch
●Oil filter bracket
●Oil cooler.
●Oil pump housing
●Vacuum pump
●Cylinder head rear cover assembly
●Chain case
●Mating surface between cylinder block and cylinder head
●Mating surface between cylinder head and rocker cover
●Crankshaft oil seal. Refer to LU-18, "ENGINE OIL LEVEL AND MUDDINESS" .
ENGINE OIL PRESSURE CHECK
WARNING:
●Be careful not to burn yourself, as the engine oil is hot.
●Oil pressure check should be done in “ Neutral position”.
1. Check the engine oil level. Refer to LU-18, "
ENGINE OIL LEVEL
AND MUDDINESS" .
2. Remove the undercover.
3. Remove the oil pressure switch to connect the oil pressure
gauge.
4. After warming up the engine, check that oil pressure corre-
sponding to the engine speed is produced.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
5. After checking, install the oil pressure switch as follows.
a. Remove old sealant adhering to the switch and engine.
b. Apply thread sealant.
Use Genuine Liquid Gasket or equivalent.

WARNING:
●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 engine oil. If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as possible.
1. Warm up engine, put vehicle horizontally and check for engine
oil leakage from engine components.
2. Stop engine and wait for 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain engine oil.
●Install drain plug and refill with new engine oil.
Engine oil specification and viscosity:
●API grade CF-4.
●ACEA B1, B3, B4, B5
●Refer to MA-16, "RECOMMENDED FLUIDS AND LUBRI-
CANTS" .
Engine oil capacity (Approximate):
●The refill capacity depends on the engine oil temperature and drain time. Use these specifications for
reference only.
Always use the dipstick to the determine when the proper amount of engine oil is in the engine.
CAUTION:
●Be sure to clean drain plug and install with new washer.
●The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.
Always use the dipstick to the determine when the proper amount of engine oil is in the
engine.
5. Warm up engine and check area around drain plug and oil filter for engine oil leakage.
6. Stop engine and wait for 10 minutes.
7. Check engine oil level. Refer to LU-18, "
ENGINE OIL LEVEL AND MUDDINESS" . Oil pressure switch:
