Oil Pump
Clearance Inspection
1. Check the clearance between the transmission
mating surface of the clutch housing and the oil
pump gear.
Standard: 0.3-0.8 mm (0.012-0.031 in)
Service Limit: 0.9 mm (0.035 in)
2. Check the axial clearance on the pump rotor.

Standard: 0.03—0.1 mm
(0.001 – 0.004 in)
Service Limit: 0.15 mm (0.006 in)
3. Check the radial clearance on the pump rotor.
Inner Rotor-to-Outer Rotor Radial clearance
Standard: 0.14 mm (0.006 in) max.
Service Limit: 0.2 mm (0.008 in)
4. Check the radial clearance between the clutch
housing and the outer rotor.
