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.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 cleaner, to remove any
used engine oil. Do not used gasoline, thinners, or sol-
vents.In order to preserve the environment, used oil and
used oil filters must be disposed of only at designated dis-
posal sites.

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 − 0.170 mm (0.0039 − 0.0067 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:
0.030 − 0.160 mm (0.0012 − 0.0063 in.)
Maximum tip clearance:
0.25 mm (0.0098 in.)
If the tip clearance is greater than maximum, replace the rotors
as a set.
