Oil Pump: Service and Repair

Oil Pump Overhaul

Oil Pump:

Special Tools Required
^ Oil seal driver, 64 mm 070AD-RCAA100

Removal
1. Drain the engine oil.
2. Remove the timing belt:
^ J35A9 engine
^ J35Z1 engine

3. Remove the crankshaft position (CKP) sensor.
4. Attach the chain hoist to the engine hanger on the power steering (P/S) pump bracket.
5. Remove the jack from under the oil pan.
6. Remove the rocker arm oil control solenoid/oil filter assembly (J35A9 engine).
7. Remove the oil filter base/oil filter assembly (J35Z1 engine).
8. Remove the oil pan.





9. Remove the oil screen (A).
10. Remove the mounting bolts and the oil pump assembly (B).

Inspection
1. Remove the screws from the pump housing, then separate the housing and cover.





2. Check the inner-to-outer rotor radial clearance between the inner rotor (A) and outer rotor (B). If the inner-to-outer rotor clearance exceeds the service limit, replace the oil pump assembly.





3. Check the housing-to-rotor axial clearance between the rotors (A) and pump housing (B). If the housing-to-rotor axial clearance exceeds the service limit, replace the oil pump assembly.





4. Check the housing-to-outer rotor radial clearance between the outer rotor (A) and pump housing (B). If the housing-to-outer rotor radial clearance exceeds the service limit, replace the oil pump assembly.
5. Inspect both rotors and pump housing for scoring or other damage. Replace the parts, if necessary.
6. Apply liquid thread lock to the pump housing screws, then install the oil pump cover.
7. Check that the oil pump turns freely.

Installation
1. Remove the old oil seal from the oil pump.





2. Gently tap in the new oil seal until the oil seal driver bottoms on the pump.
3. Remove all of the old liquid gasket from the oil pump mating surfaces, bolts, and bolt holes.
4. Clean and dry the oil pump mating surfaces.





5. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0002, 08718-0003, or 08718-0009, evenly to the engine block mating surface of the oil pump.

NOTE: Do not install components if too much time has passed after applying the liquid gasket (for P/N 08718-0002, no more than 4 minutes, for all others, no more than 5 minutes). Instead, remove the old residue and reapply the liquid gasket.





6. Grease the lip of the oil seal, and apply oil to the new O-ring (A).
7. Install the dowel pins (B), then align the inner rotor with the crankshaft, and install the oil pump (C).

NOTE:
^ Wait at least 30 minutes before filling the engine with oil.
^ Do not run the engine for at least 3 hours after installing the oil pump.

8. Clean the excess grease off the crankshaft, and check the seal for distortion.
9. Install the oil screen (D) with new O-ring (E).
10. Install the rocker arm oil control solenoid/oil filter assembly (J35A9 engine).
11. Install the oil filter base/oil filter assembly (J35Z1 engine).
12. Install the oil pan.
13. Install the crankshaft position (CKP) sensor.
14. Install the timing belt:
^ J35A9 engine
^ J35Z1 engine

15. Remove the chain hoist.
