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. PLACE DRIVE AND DRIVEN ROTORS INTO OIL PUMP
BODY
Place the drive and driven rotors into the oil pump body with the
mark facing upward.
3. INSPECT ROTOR SIDE CLEARANCE
Using a feeler 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 feeler 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: 0.35 mm (0.0138 in.)
If the tip clearance is greater than maximum, replace the rotors
as a set.
5. INSPECT ROTOR BODY CLEARANCE
Using a feeler gauge, measure the clearance between the driv-
en rotor and body.
Standard body clearance:
0.250 - 0.325 mm (0.0098 - 0.0128 in.)
Maximum body clearance: 0.40 mm (0.0157 in.)
If the body clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
