Oil Pump Clearance - Inspect
1.
Measure the thrust clearance between the oil pump rotors (A) and the clutch housing (B) with a straight edge (C) and a feeler gauge (D).
Standard (new):
0.03?0.13 mm (0.002?0.005 in)
Service Limit:
0.13 mm (0.005 in)
2.
Measure the side clearance between the oil pump outer rotor (A) and the clutch housing (B) with a feeler gauge (C).
Standard (new):
0.1?0.2 mm (0.004?0.008 in)
Service Limit:
0.2 mm (0.008 in)
3.
Measure the side clearance between the oil pump outer rotor (A) and the oil pump inner rotor (B) with a feeler gauge (C).
Standard (new):
0.1?0.4 mm (0.004?0.016 in)
Service Limit:
0.4 mm (0.016 in)
4.
If any clearance is not within the standard, replace the oil pump outer and inner rotors as a set.
