Torque Converter: Testing and Inspection
Stator to Impeller Interference Check
1. CAUTION: To perform this check, do not use the pump stator support which will be installed in the transmission. Damage to the pump stator
support, front pump seal or front pump stator seal may occur.
NOTE: Obtain a scrapped pump stator support as a permanent tool to perform this check.
NOTE: A pump stator support can remain in the pump assembly during this test.
Position the stator support with the splines up.
2. NOTE: The assembled pump can be used for the following steps.
Mount the (A) torque converter on the (B) stator support so that the splines on the one-way clutch inner race engage the mating splines of the
stator support.
3. Hold the stator support stationary and rotate the torque converter counterclockwise.
-
The torque converter should rotate freely, with no signs of scraping.
-
If there are signs of scraping, replace the torque converter.
