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)

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.
