Oil Pump: Inspection

  1. Check oil pump body for cracks or wear. Inspect pump gears for cracks, wear or damage. Check shaft for looseness in housing. Replace pump as a unit if any parts are not to specification.
  2. Check inside of cover for wear that would permit oil to leak past ends of gears. Check oil pick-up screen for damage to screen or relief grommet. Remove debris from surface of screen.
  3. When assembling oil pump, fill cavities with petroleum jelly to ensure immediate oil pressure. Install cover, tighten bolts and ensure shaft turns freely. Install regulator valve plunger, spring, retainer and pin.
