OIL PUMP





COMPONENTS

DISASSEMBLY
1. Remove the oil pressure switch, using 24 mm deep socket.

NOTE: Since a sealant is used on the threaded area, be careful not to damage the oil pressure switch.

2. Remove the oil filter and the oil pan.
3. Remove the oil screen and gasket.
4. Remove the three bracket securing bolts and remove the oil filter bracket and gasket.
5. Remove the oil relief valve plug from the oil pump case.





6. Remove the oil pump case.

INSPECTION
OIL PUMP
1. Visually check the parts of the oil pump case for cracks and damage.








2. Assemble the rotor on the oil pump and then check the clearance with a thickness gauge.
Oil pump side clearance
Standard value
Body clearance: 0.100 - 0.181 mm (0.0039 - 0.0071 inch)
Side clearance: 0.040 - 0.095 mm (0.0016 - 0.0037 inch)
Oil pump Tip clearance: 0.06 - 0.18 mm (0.0024 - 0.0071 inch)

RELIEF PLUNGER AND SPRING
1. Check the relief plunger for smooth operation.
2. Check the relief spring for deformation or breaks.

OIL FILTER BRACKET
1. Make sure that there is no damage on the surface that mates with the on filter.
2. Check the oil filter bracket for oil leaks or cracks.

OIL PRESSURE SWITCH





1. Check the continuity between the terminal and the body with an ohmmeter. If there is no continuity, replace the oil pressure switch.
2. Check the continuity between the terminal and the body when the fine wire is pushed. If there is continuity even when the fine wire is pushed, replace the switch.





3. If there is no continuity when a 50 kpa (0.5 kg/cm2, 7 psi) vacuum is applied through the oil hole, the switch is operating properly. Check for air leakage. If air leaks, the diaphragm is broken. Replace it.
Operation Pressure
Oil pressure switch: 19.6 - 39.2 kpa (0.2 - 0.4 kg/cm2, 2.8 - 5.7 psi) or more

REASSEMBLY





1. Install the oil pump case with the gasket.
Tightening torque
Oil pump case bolt: 12 - 15 Nm (120 - 150 kg-cm, 9 - 11 ft. lbs.)
Oil pump cover screw: 8 - 12 Nm (80 - 120 kg-m, 6 - 9 ft. lbs.)





2. Install the oil seal into the oil pump case as tightly as possible, using the special tool (09214-33000).





3. Install the relief plunger and spring, and tighten the oil relief valve plug to the specified torque.
Tightening torque
Oil relief valve plug: 40 - 50 Nm (400 - 500 kg-cm, 29 - 36 ft. lbs.)
4. Install the oil screen and a new gasket.
Tightening torque
Oil screen bolt: 15 - 22 Nm (150 - 220 kg-cm, 11 - 15 ft. lbs.)
5. Clean the gasket surfaces of the cylinder block and the oil pan.





6. Apply sealant to the groove of the oil pan flange.

NOTE:
^ Make the first cut approximately 4 mm from the end of the nozzle furnished with the sealant. After application of the sealant, do not exceed 15 minutes before installing the oil pan.
^ Make sure that the sealant doesn't enter the inside of the oil pan.





7. Tighten the oil pan bolts as shown in the illustration.
Tightening torque
9.8 - 11.8 Nm (100 - 120 kg-cm, 7.2 - 8.7 ft. lbs.)
4.9 - 6.9 Nm (50 - 70 kg-cm, 3.6 - 5.1 ft. lbs.) (No. 15. 16)





8. Tighten the transmission mounting bolts from oil pan.
Tightening torque (mounting bolts) 29.4 - 41.2 Nm (300 - 420 kg-cm, 21.7 - 30.4 ft. lbs.)





9. Using a 24 mm deep socket, install the oil pressure switch after applying sealant to the threaded area.
Sealant: Three bond No. 1104E or equivalent

NOTE: Do not torque the oil pressure switch too much.

Tightening torque
Oil pressure switch: 8 - 12 Nm (80 - 120 kg-cm, 6 - 9 ft. lbs.)





10. Tighten the lower oil pan bolts as shown in figure.
Tightening torque 9.8 - 11.8 Nm 1100 - 120 kg-cm, 7.2 - 8.7 ft. lbs.)
