DISASSEMBLY
1. REMOVE FRONT CRANKSHAFT OIL SEAL
(a) Using a screwdriver, pry out the oil seal.
NOTICE: Do not damage the surface of the oil seal press fit hole.
2. REMOVE OIL PUMP RELIEF VALVE
(a) Remove the plug, compression spring and relief valve.
3. REMOVE OIL PUMP COVER
(a) Remove the 10 screws, pump cover and drive and driven rotors.
INSPECTION
1. INSPECT OIL PUMP RELIEF VALVE
(a) Coat the relief valve with engine oil and drop it into the relief valve hole.
(b) Check that the relief valve falls in smoothly by its own weight.
If it does not, replace the relief valve. If necessary, replace the oil pump assembly.
2. INSPECT OIL PUMP ROTOR SET
(a) Place the drive and driven rotors into the pump body with the marks facing the pump body cover side.
(b) Inspect 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 (0.00236 to 0.00709 in.)
Maximum tip clearance: 0.18 mm (0.00709 in.)
If the tip clearance is greater than the maximum, replace the rotors as a set.
(c) Inspect the rotor side clearance.
(1) Using a feeler gauge and precision straightedge, measure the clearance between the rotors and precision straightedge.
Standard side clearance: 0.030 to 0.090 mm (0.00118 to 0.00354 in.)
Maximum side clearance: 0.09 mm (0.00354 in.)
If the side clearance is greater than the maximum, replace the rotors as a set. If necessary, replace the oil pump assembly.
(d) Inspect the rotor body clearance.
(1) Using a feeler gauge, measure the clearance between the driven rotor and body.
Standard body clearance: 0.250 to 0.325 mm (0.00984 to 0.0128 in.)
Maximum body clearance: 0.325 mm (0.0128 in.)
If the body clearance is greater than the maximum, replace the rotors as a set. If necessary, replace the oil pump assembly.
REASSEMBLY
1. INSTALL OIL PUMP ROTOR SET
(a) Place the drive and driven rotors into the pump body with the marks facing the pump body cover side.
(b) Install the oil pump cover with the 10 screws.
Torque: 10 N*m (102 kgf*cm, 7 ft.*lbf)
2. INSTALL OIL PUMP RELIEF VALVE
(a) Insert the relief valve and compression spring into the oil pump body hole.
(b) Install the plug.
Torque: 49 N*m (500 kgf*cm, 36 ft.*lbf)
3. INSTALL FRONT CRANKSHAFT OIL SEAL
(a) Using SST and a hammer, tap in a new oil seal until its surface is flush with the oil pump body edge.
SST 09316-60011 (09316-00011)
NOTICE:
^ Keep the lip free from foreign matter.
^ Do not tap oil seal at an angle.
(b) Apply MP grease to the oil seal lip.
