- Oil pump driven gear «1»
- Oil pump rotor housing «2»
- Oil pump cover
Cracks/damage/wear → Replace the defective part(s).
2. Measure:
- Inner-rotor-to-outer-rotor-tip clearance «a»

Limit: 0.18 mm (0.0071 in)
Outer-rotor-to-oil-pump-housing clearance: 0.090-0.150 mm (0.0035-0.0059 in)
Limit: 0.22 mm (0.0087 in)
1. Oil pump inner rotor; 2. Oil pump outer rotor; 3. Oil pump housing
3. Check:
- Oil pump operation
Rough movement → Repeat steps (1) and (2) or replace the defective part(s).
