INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SL Energy±Conserving or ILSAC multi-
grade engine oil.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ºLº and ºFº marks on the dip-
stick.
If low, check for leakage and add oil up to the ºFº mark.
NOTICE:
Do not fill with engine oil above the ºFº mark.
3. REMOVE ENGINE UNDER COVER

REPLACEMENT
CAUTION:

Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addi-
tion, used engine oil contains potentially harmful
contaminants which may cause skin cancer.

Care should be taken, therefore, when changing en-
gine 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
cleaner, to remove any used engine oil. Do not use
gasoline, thinners, or solvents.

In order to preserve the environment, used oil and
used oil filters must be disposed of only at desig-
nated disposal sites.
1. w/ Oil filter change:
REMOVE ENGINE UNDER COVER
2. DRAIN ENGINE OIL
(a) Remove the oil filler cap.
(b) Remove the oil drain plug and gasket, and drain the oil
into a container.
3. REPLACE OIL FILTER
(a) Using SST, remove the oil filter.
SST 09228±07501
(b) Clean the oil filter contact surface on the oil filter mount-
ing.
(c) Lubricate the filter rubber gasket with clean engine oil.

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 doesn't, replace the relief valve. If necessary, replace the oil
pump assembly.
2. INSPECT DRIVE AND DRIVEN ROTORS
(a) Place the drive and driven rotors into the oil pump body.
(see page LU±14)
(b) Inspect the rotors for the body clearance.
Using a feeler gauge, measure the clearance between
the drive and driven rotor tips.
Standard tip clearance:
0.060 to 0.180 mm (0.0024 to 0.0071 in.)
Maximum tip clearance: 0.18 mm (0.0071 in.)
If the tip clearance is greater than maximum, replace the rotors
as a set.
(c) Inspect the rotors for the side clearance.
Using a feeler gauge and precision straight edge, mea-
sure the clearance between the rotors and precision
straight edge.
Side clearance:
0.030 to 0.090 mm (0.0012 to 0.0035 in.)
Maximum body clearance: 0.09 mm (0.0035 in.)
If the side clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
(d) Inspect the rotor for the body clearance.
Using a feeler gauge, measure the clearance between
the driven rotor and body.
Standard body clearance:
0.250 to 0.325 mm (0.0098 to 0.0128 in.)
Maximum body clearance: 0.325 mm (0.0128 in.)
If the body clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
(e) Remove the drive and drive rotors.
