DISASSEMBLY





1. REMOVE OIL PUMP COVER
(a) Remove the 2 bolts and 3 screws and remove the oil pump cover.





2. REMOVE OIL PUMP ROTOR SET
(a) Remove the oil pump rotor set.





3. REMOVE OIL PUMP RELIEF VALVE
(a) Remove the oil pump relief valve plug, oil pump relief valve spring and oil pump relief valve.

INSPECTION





1. INSPECT OIL PUMP RELIEF VALVE
(a) Coat the oil pump relief valve with engine oil and check that it falls smoothly into the valve hole under its own weight.

If not, replace the oil pump relief valve. If necessary, replace the oil pump assembly.





2. INSPECT OIL PUMP ROTOR SET
(a) Install the 2 rotors with both of the marks facing the oil pump cover side.





(b) Check the rotor tip clearance.
(1) 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: 0.28 mm (0.0110 in.)

If the tip clearance is greater than the maximum, replace the oil pump assembly.





(c) Check the rotor body clearance.
(1) Using a feeler gauge, measure the clearance between the driven rotor and the oil pump body.
Standard body clearance: 0.250 to 0.325 mm (0.0098 to 0.0128 in.)
Maximum body clearance: 0.425 mm (0.0167 in.)

If the body clearance is greater than the maximum, replace the oil pump assembly.

REASSEMBLY





1. INSTALL OIL PUMP RELIEF VALVE
(a) Coat the oil pump relief valve with engine oil and insert the oil pump relief valve and oil pump relief valve spring into the oil pump cover.
(b) Install the oil pump relief valve plug.
Torque: 25 N*m (255 kgf*cm, 18 ft.*lbf)





2. INSTALL OIL PUMP ROTOR SET
(a) Coat the oil pump rotor set with engine oil and place it into the oil pump body with the marks facing the oil pump cover side.





3. INSTALL OIL PUMP COVER
(a) Install the oil pump cover with the 2 bolts and 3 screws.
Torque: 8.8 N*m (90 kgf*cm, 78 in.*lbf) for bolt
10 N*m (105 kgf*cm, 7.6 ft.*lbf) for screw
