Position the front pump assembly on a bench with the spline end of the
stator shaft pointing up.
Mount a converter on the pump with the splines on the one-way clutch inner
race, engaging the mating splines of the stator support. The converter hub will
then engage the pump drive gear.
Hold the pump stationary, and try to rotate the converter counterclockwise.
The converter should rotate freely without any signs of interference or
scraping within the converter assembly.
If there is an indication of scraping, the trailing edges of the stator
blades may be interfering with the leading edges of the impeller blades. In
such cases, replace the converter.
