Stator-To-Impeller Interference Check

1. Position stator support shaft on bench with spline end pointing up. Mount converter vertically onto shaft so support shaft splines engage one-way clutch splines. See Fig 1.
2. While holding support shaft stationary, rotate converter counterclockwise. Converter should rotate freely without interference or scraping within assembly. Should interference or a scraping condition within converter exist or converter does not rotate freely, replace converter unit.
