Removal

1. Drain the engine oil.
2. Remove the timing belt (see page 6-18).
3. Remove the oil pan.
4. Remove the oil screen (A).

5. Remove the mounting bolts and the oil pump assembly (B).
6. Remove the screws from the pump housing, then separate the housing and cover.

Inspection

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

   Inner Rotor-to-Outer Rotor Radial Clearance

   Standard (New): | 0.02 - 0.07 mm (0.001 - 0.003 in.)
   Service Limit | 0.15 mm (0.006 in.)

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

   Housing-to-Rotor Axial Clearance

   Standard (New): | 0.02 - 0.07 mm (0.001 - 0.003 in.)
   Service Limit | 0.15 mm (0.006 in.)
