Oil Pump: Inspection
WARNING: This page is about a different variant/trim than selected.
- Inspect components for damage. Ensure relief valve slides freely in bore. Install inner and outer rotors in oil pump body. Using feeler gauge, measure clearance between outer rotor and oil pump body. See OIL PUMP SPECIFICATIONS .
- Measure rotor tip clearance between tips of both rotors. Place straightedge across oil pump body, above both rotors. Measure rotor end clearance between straightedge and rotor surface. Replace rotor assembly or oil pump body if any measurement exceeds specification.
- Measure free length of spring for relief valve. Replace spring if free length is not 1.842" (46.79 mm).
