3. Hold the (A) front pump support stationary and rotate the (B) torque converter counterclockwise.
-
The torque converter should rotate freely with no signs of scraping.
-
If there are signs of scraping, replace the torque converter.
Stator to Turbine Interference Check
1. NOTE: Front pump support may remain in front pump support and gear during this test.
Position the torque converter with the pump drive up.
2. Install the (A) front pump support to engage the mating splines of the front pump support shaft on the (B) torque converter.
3. Install the forward clutch cylinder and shaft engaging the splines with the rear clutch hub.
4. Check for stator to turbine interference.
1
Hold the front pump support stationary.
2
Attempt to rotate 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.
-
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.
