Engine Oil Pump Overhaul
Inspection
  1. Remove the screws from the oil pump housing, then separate the pump housing and pump cover.
  1. Check the inner-to-outer rotor radial clearance between the inner rotor (A) and the outer rotor (B). If the inner-to-outer rotor clearance exceeds the service limit, replace the oil pump assembly.
