Oil Pump: Inspection
WARNING: This page is about a different variant/trim than selected.
Measure radial clearance between inner and outer rotors. Measure axial clearance between housing and outer rotor. Inspect both rotors and pump housing for scoring or other damage. Replace components if clearance measurements are not within specification. See OIL PUMP SPECIFICATIONS table.
