Stator to Turbine Interference Check

NOTE: Front pump support (7A108) may remain in front pump support and gear (7A103) during this test.

  1. Position the torque converter (7902) on the bench, front side down.
  1. Install a front pump support to engage the mating splines of the front pump support shaft.
  1. Install the forward clutch cylinder and shaft (7F207), engaging the splines with the rear clutch hub (7B067).



  1. 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 lb-ft) without any signs of metallic interference or scraping noise.
  1. 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 (6303). Check the converter front impeller hub for nicks or sharp edges that would damage the pump seal.

 

End Play Check

SPECIAL SERVICE TOOL(S) REQUIRED
Description Tool Number
End Play Checking Tool T80L-7902-A

  1. Insert End Play Checking Tool T80L-7902-A into the torque converter pump drive hub until it bottoms.
  1. Expand the sleeve in the turbine spline by tightening the threaded inner post until the tool is securely locked in to the spline.



  1. Attach Dial Indicator with Bracketry TOOL-4201-C or equivalent to the tool. Position the indicator button on the converter pump drive hub, and set the dial face at 0 (zero).
  1. Lift the tool upward as far as it will go and note the indicator reading. The indicator reading is the total end play which the turbine and stator share. Replace the torque converter if the total end play exceeds the limits indicated in the chart below.
  1. Loosen the threaded inner post to free the tool and remove the tool from the torque converter. Refer to the following chart for torque converter end-play specifications.
