Stator-To-Impeller Interference Check

  1. Position overdrive pump assembly on bench with spline end of stator shaft pointing upward. Mount converter on pump so splines of one-way clutch inner race engage splines of stator support and impeller hub engages pump drive gear.
  2. While holding pump stationary, rotate converter in both directions (clockwise and counterclockwise). Converter should rotate freely without interference. If an interference or scraping condition exists, replace torque converter unit.
