Oil Pump: Inspection

  1. Check oil seal for damage. Inspect outer and inner gears, gear plate and oil pump case for wear or damage. Replace components as necessary.
  2. Using a feeler gauge, measure radial clearance between outer gear and crescent. If clearance exceeds .012" (.31 mm) replace outer gear. Using a straightedge and feeler gauge, measure side clearance. If pump side clearance exceeds .006" (.15 mm), replace oil pump assembly.
