Oil Pump Clearance
• Measure the clearance with feeler gauge (C).
- Clearance between oil pump outer rotor and oil pump body [posi-
tion (B)]
- Tip clearance between oil pump inner rotor and oil pump outer
rotor [position (A)]
• Measure the clearance with feeler gauge and straightedge (A).
- Side clearance between oil pump inner rotor and oil pump body
[position (C)]
- Side clearance between oil pump outer rotor and oil pump body
[position (B)]
• Calculate the clearance between oil pump inner rotor and oil pump body as follows:
OIL PUMP BODY INNER DIAMETER
- Measure the inner diameter of oil pump body with inside microme-
ter. [position (A)]
OIL PUMP INNER ROTOR OUTER DIAMETER
- Measure the outer diameter of protruded portion of oil pump inner
rotor (1) with micrometer. [position (B)]
OIL PUMP INNER ROTOR TO OIL PUMP BODY CLEARANCE
- (Clearance) = (Oil pump body inner diameter) – (Oil pump inner rotor outer diameter)
