REMOVAL
CAUTION:
lBe careful not to get burned when the engine and engine oil
are hot.
lWhen removing, prepare a shop cloth to absorb any oil
leakage or spillage.
lDo not allow engine oil to adhere to the drive belts.
lCompletely wipe off any oil that adhere to the engine and
the vehicle.
1. Using a socket wrench [plane-to-plane width: 17 mm (0.67 in)],
loosen the filter body approximately four turns.
2. Drain the oil after matching the "DRAIN" arrow mark at the bot-
tom of the filter body to the protrusion on the oil filter bracket.
lCatch the oil with a pan or cloth.
CAUTION:
lThe drained oil flows over the right surface of the filter
body.
lCompletely wipe clean any engine oil remaining on the
filter body or vehicle.
3. Remove the filter body, then remove the oil filter element.

4. Remove the O-ring from the filter body.
lPush the O-ring in one direction, lift the slack part using fin-
gers, 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.
INSTALLATION
1. 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.
lPush the oil filter element into the filter body completely.
3. Install the filter body to the oil filter bracket.
4. After warming up the engine, check for engine oil leakage.
5. Check oil level and add engine oil. Refer toLU-7, "
ENGINE OIL"

lRemove front cover. Refer to Primary Timing ChainEM-163, "PRIMARY TIMING CHAIN".
Disassembly and AssemblyEBS00B07
CAUTION:
Before installation, apply new engine oil to the parts as instructed in the figure.
DISASSEMBLY
1. Remove oil pump cover.
2. Remove inner rotor and outer rotor from oil pump housing.
3. After removing regulator plug, remove regulator spring and regulator valve.
INSPECTION AFTER DISASSEMBLY
Clearance of Oil Pump Parts
lMeasure clearance with feeler gauge.
Clearance between outer rotor and oil pump housing (position 1)
Tip clearance between inner rotor and outer rotor (position 2)
lMeasure clearance with feeler gauge and straightedge.
Side clearance between inner rotor and oil pump housing (posi-
tion 3)
Side clearance between outer rotor and oil pump housing (posi-
tion 4)

OIL PUMP
lCalculate the clearance between inner rotor and oil pump hous-
ing as follows.
1. Measure the outer diameter of protruded portion of inner rotor
(Position 5)
2. Measure the inner diameter of oil pump housing with inside
micrometer (Position 6)
(Clearance) = (Inner diameter of oil pump housing) – (Outer
diameter of inner rotor)
Regulator Valve
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 housing.
4. Check regulator valve to oil pump housing clearance.
CAUTION:
Coat regulator valve with engine oil.
Check that it falls smoothly into the valve hole by its own
weight.
ASSEMBLY
lAssemble in the reverse order of disassembly.
lInstall the inner rotor and outer rotor with the punched marks on
the oil pump cover side.
lThe refill capacity depends on the oil temperature and drain
time. Use these specifications for reference only.
Always use the dipstick to the determine when the proper
amount of oil is in the engine.
