Oil Pump: Inspection
WARNING: This page is about a different variant/trim than selected.
- Inspect components for damage. Using straightedge and feeler gauge, measure gear end clearance. Measure housing pocket depth and diameter. Measure gear diameter and length (thickness). Measure side clearance between gear tooth and housing.
- Measure gear lash clearance between the gear teeth. Check clearance between the pressure regulator valve and bore. Replace components or pump assembly if not within specification. Refer to OIL PUMP SPECIFICATIONS table.
