Oil Pump: Inspection

  1. Wash all parts in solvent and dry with compressed air. Inspect pump body and cover for cracks or excessive wear.
  2. Inspect gears for damage or excessive wear. Check for looseness of drive gear shaft in body.
    NOTE: The pump gears and pump body cannot be serviced separately. If either gears or pump body is worn or damaged, replace entire oil pump assembly.
  3. Inspect pump cover for wear that would allow oil to leak past ends of gears. Inspect pick-up screen and tube assembly for damage. Check pressure regulator valve for fit in pump body.
