INSPECTION
1. INSPECT RELIEF VALVE
Coat the valve with engine oil and check that it falls smoothly
into the valve hole by its own weight.
If it does not, replace the relief valve. If necessary, replace the
oil pump assembly.
2. INSPECT ROTOR BODY CLEARANCE
Using a thickness gauge, measure the clearance between the
driven rotor and body.
Standard body clearance:
0.100 − 0.175 mm (0.0039 − 0.0069 in.)
Maximum body clearance:
0.30 mm (0.0118 in.)
If the body clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
3. INSPECT ROTOR SIDE CLEARANCE
Using a thickness gauge and precision straight edge, measure
the clearance between the rotors and precision straight edge.
Standard side clearance:
0.030 − 0.090 mm (0.0012 − 0.0035 in.)
Maximum side clearance:
0.15 mm (0.0059 in.)
If the side clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
4. INSPECT ROTOR TIP CLEARANCE
Using a thickness gauge, measure the clearance between the
drive and driven rotor tips.
Standard tip clearance:
0.110 − 0.240 mm (0.0043 − 0.0094 in.)
Maximum tip clearance:
0.25 mm (0.0098 in.)
If the tip clearance is greater than maximum, replace the rotors
as a set.

OIL AND FILTER
INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If oil quality is visibly poor, replace it.
Oil grade:
API grade SH Energy−Conserving II or ILSAC multi-
grade engine oil.
SAE 5W−30 is the bset choise for your vehicle, for
good fuel economy, and good starting in cold
weather.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ”L” and ”F” marks on the dip-
stick.
3. CHECK OIL LEVEL
The oil level should be between the ”L” and ”F” marks on the lev-
el gauge. If low, check for leakage and add oil up to the ”F” mark.
If low, check for leakage and add oil up to the ”F” mark.
When inserting the oil dipstick, insert the curved tip of the
dipstick facing the same direction as the curve of the
guide.If the dipstick gets caught while inserting it, do not
force it in. Reconfirm the direction of the dipstick.
4. REMOVE OIL PRESSURE SWITCH
Using SST, remove the oil pressure switch.
SST 09816−30010
5. INSTALL OIL PRESSURE GAUGE
6. START ENGINE
Start the engine and warm it up to normal operating tempera-
ture.
7. CHECK OIL PRESSURE
Oil pressure:
At idle speed
29 kPa (0.3 kgf/cm
2, 4.3 psi) or more
At 3,000 rpm
245 − 520 kPa (2.5 − 5.3 kgf/cm
2, 36 − 75 psi)

REPLACEMENT
CAUTION:
Prolonged and repeated contact with mineral oil will result
in the removal of natural fats from the skin, leading to dry-
ness, irritation and dermatitis.In addition, used engine oil
contains potentially harmful contaminants which may
cause skin cancer.
Adequate means of skin protection and washing facilities
should be provided.Care should be taken, therefore, when
changing engine oil, to minimize the frequency and length
of time your skin is exposed to used engine oil.
Protective clothing and gloves, that cannot be penetrated
by oil, should be worn. The skin should be thoroughly
washed with soap and water, or use water−less hand clean-
er, to remove any used engine oil. Do not use gasoline, thin-
ners, or solvents.In order to preserve the environment,
used oil and used oil filters must be disposed of only at
designated disposal sites.
1. DRAIN ENGINE OIL
(a) Remove the oil filler cap.
(b) Remove the oil dipstick.
(c) Remove the oil drain plug and gasket, and drain the oil
into a container.
2. REPLACE OIL FILTER
(a) Using SST, remove the oil filter (located on left side of the
cylinder block).
SST 09228−07501
(b) Clean the filter contact surface on the filter mounting.
(c) Apply clean engine oil to the gasket of a new oil filter.
(d) Lightly screw the oil filter into place, and tighten it until the
gasket contacts the seat.
(e) Using SST, tighten it an additional 3/4 turn.
