For 1990-2009 cars only
- Push the driven gear to one side of the body. Using a feeler gage, measure the clearance.
- Measure the tip clearance between the driven gear teeth and drive gear teeth.
- Using a steel straight edge and feeler gage, measure the side clearance of both gears.
- Using a dial indicator, measure the inside diameter of the oil pump body bushing.
- Using a dial indicator, measure the inside diameter of the stator shaft bushings.
Important: If the body clearance is greater than the maximum, replace the oil pump body sub-assembly.
