Oil Pump: Specifications

Oil Pump Clearance





^ Measure the clearance with feeler gauge.
- Clearance between oil pump outer rotor and oil pump body (position 1)
Standard : 0.120 - 0.195 mm (0.0047 - 0.0077 inch)
- Tip clearance between oil pump inner rotor and oil pump outer rotor (position 2)
Standard : 0.06 - 0.16 mm (0.0024 - 0.0063 inch)





^ Measure the clearance with feeler gauge and straightedge.
- Side clearance between oil pump inner rotor and oil pump body (position 3)
Standard : 0.030 - 0.070 mm (0.0012 - 0.0028 inch)
- Side clearance between oil pump outer rotor and oil pump body (position 4)
Standard : 0.05 - 0.09 mm (0.0020 - 0.0035 inch)
^ Calculate the clearance between oil pump inner rotor and oil pump body as follows:

OIL PUMP INNER ROTOR TO OIL PUMP BODY CLEARANCE
- (Clearance) = (Oil pump body inner diameter) - (Oil pump inner rotor outer diameter)
Standard : 0.045 - 0.091 mm (0.0018 - 0.0036 inch)
^ If measured/calculated values are out of the standard, replace oil pump assembly.
