Torque Converter: Testing and Inspection

TORQUE CONVERTER CLUTCH AND DRIVE PLATE INSPECTION






1. Inspect one-way clutch.
a. Install Special Service Tool (SST) 09350-32014 (09351-32020) or equivalent, into the inner race of the one-way clutch.





b. Install SST 09350-32014 (09351-32010) so that it fits in the notch of the converter hub and outer race of the one-way clutch.





c. With the torque converter clutch standing on its side, the clutch locks when turned counterclockwise, and rotates freely and smoothly clockwise. If necessary, clean the converter and retest the clutch. Replace the converter if the clutch still fails the test.
2. Measure drive plate runout and inspect ring gear.





a. Set up a dial indicator, and measure the drive plate runout.
b. Check the damage of the ring gear.
Maximum runout: 0.20 mm (0.0079 in.)
If runout is not within specification or ring gear is damaged, replace the drive plate.
Torque: 83 N.m (850 kgf-cm, 61 ft. lbs.)
3. Measure torque converter clutch sleeve runout.





a. Temporarily mount the torque converter clutch to the drive plate. Set up a dial indicator and measure the torque converter clutch sleeve runout.
Maximum runout: 0.30 mm (0.0118 in.)
If the runout is not within the specification, try to correct by reorienting the installation of the converter.

HINT: Mark the position of the converter to ensure the correct installation.

b. Remove the torque converter clutch.
