Removal/Inspection/Installation (page 2 of 3)

If the housing – to – rotor axial clearance exceeds the service limit, replace the set of inner and outer rotors and/or the pump housing.

• A Pump Housing
• B Outer Rotor

12. Check the housing – to – outer rotor radial clearance.
    Housing – to – Outer Rotor Radial Clearance:
    Standard (New): 0.10 ÷ 0.19 mm
    Service Limit: 0.21 mm
    If the housing – to – outer rotor radial clearance exceeds the service limit, replace the set of inner and outer rotors and/or the pump housing.
13. Inspect both rotors and the pump housing for scoring or other damage. Replace parts if necessary.
14. Remove the old oil seals from the oil pump.

15. Gently tap in the new oil seals until the special tool bottoms on the pump.

Note: The oil seals alone can be replaced without removing the oil pump using the special tool.

16. Reassemble the oil pump, applying liquid thread lock to the pump housing screws.
17. Check that the oil pump turns freely.
18. Install a dowel pin and new O – rings on the pump.

• A Broken Line

19. Apply liquid gasket to the oil pump, along the broken lines shown, and install it.

Note:

• Use liquid gasket.
• Check that the mating surfaces are clean and dry before applying liquid gasket.
• Apply liquid gasket evenly, in a narrow bead centred on the mating surface.
• To prevent leakage of oil, apply liquid gasket to the inner threads of the bolt holes and the threads of the bolts.
