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 a 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. See OIL PUMP SPECIFICATIONS . If bushing inside diameter exceeds specification, oil pump housing or stator shaft must be replaced. Replace necessary components to obtain correct clearances.
