10. Remove the oil pump.
Oil Pump Inspection
1. Remove the screws from the pump housing, then separate the pump housing and the pump cover.
2. Check the inner rotor-to-outer rotor radial clearance between the inner rotor (A) and the outer rotor (B). If the inner rotor-to-outer rotor clearance exceeds the service limit, replace the oil pump.
3. Check the pump housing-to-rotor axial clearance between the rotors (A) and the pump housing (B). If the pump housing-to-rotor axial clearance exceeds the service limit, replace the oil pump.
4. Check the pump housing-to-outer rotor radial clearance between the outer rotor (A) and the pump housing (B). If the pump housing-to-outer rotor radial clearance exceeds the service limit, replace the oil pump.
5. Inspect both rotors and the 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.
Oil Pump Installation
1. Check the oil pump oil seal for damage. If the oil seal is damaged, replace the oil seal Cam Chain Case Oil Seal Installation.
2. Remove all of the old liquid gasket from the oil pump mating surfaces, the bolts, and the bolt holes.
3. Clean and dry the oil pump mating surfaces.
4. Apply liquid gasket, P/N 08717-0004, 08718-0003, or 08718-0009 to the engine block mating surface of the oil pump, and to the inside edge of the threaded bolt holes. Install the component within 5 minutes of applying the liquid gasket.
NOTE:
- Apply a 2.5 mm (0.098 in) diameter bead of liquid gasket along the broken line (A), (B), and (C).
- If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply new liquid gasket.
5. Apply liquid gasket, P/N 08717-0004, 08718-0003, or 08718-0009 to the oil pan mating surface of the oil pump, and to the inside edge of the threaded bolt holes. Install the component within 5 minutes of applying the liquid gasket.
NOTE:
- Apply a 2.5 mm (0.098 in) diameter bead of liquid gasket along the broken line (A).
- If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply new liquid gasket.
6. Install new O-rings (A) on the oil pump. Set the edge of the oil pump (B) on the edge of the oil pan (C), then install the oil pump on the engine block (D). Loosely install the dowel bolts (E), then tighten the 8 mm bolts (F), the 6 mm bolts (G) and the dowel bolts. Wipe off the excess liquid gasket on the oil pan and oil pump mating surface.
NOTE:
- When installing the oil pump, do not slide the bottom surface onto the oil pan mounting surface.
- Wait at least 30 minutes before filling the engine with oil.
- Do not run the engine within 3 hours after installing the oil pump.
7. Install the side engine mount bracket (A), then loosely tighten the new bolt and nut (B), then loosely tighten the bolt (C).
8. Install the ground cable (D).
9. Remove the air cleaner Service and Repair.
10. Loosen the transmission mount bracket mounting bolt and nuts (A).
