Stator to Turbine Interference Check

1. Position the torque converter on the bench, front side down.

NOTE: Front pump support may remain in front pump support and gear during this test.

2. Install front pump support to engage the mating splines of the front pump support shaft.





3. Install the forward clutch cylinder and shaft, engaging the splines with the rear clutch hub.
4. Hold the stator shaft stationary and attempt to rotate the rear clutch hub with the forward clutch cylinder and shaft. The turbine and torque converter clutch assemblies should rotate in both directions not exceeding maximum torque of 9.5 Nm (7 ft. lbs.) without any signs of metallic interference or scraping noise.
5. If interference exists, the stator front thrust washer may be worn, allowing the stator to hit the turbine. In such cases, the torque converter must be replaced.
6. The converter crankshaft pilot should be checked for nicks or damaged surfaces that could cause interference when installing the torque converter into the crankshaft. Check the converter front impeller hub for nicks or sharp edges that would damage the pump seal.
