Oil Pump: Inspection
- Clean all components in solvent. Dry with compressed air. Inspect all components for damage or wear. Measure inside diameter of oil pump housing and stator shaft bushings. Measure driven gear-to-housing clearance and gear tip clearance. Using feeler gauge and straightedge, measure gear side clearance between pump housing face and top of gears. See Fig 2.
- Ensure all measurements are within specification. Refer to the OIL PUMP SPECIFICATIONS table. If bushing inside diameter exceeds specification, oil pump housing or stator shaft must be replaced. Replace necessary components to obtain correct clearances.
