SST 09350-32020 (09351-32020)





c. With the torque converter standing on its side, check that 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

b. Check the damage of the ring gear.

Maximum runout: 0.20 mm (0.0079 inch)

If the runout is not within the specification or ring gear is damaged, replace the drive plate.

Torque: 83 Nm (850 kgf-cm 61 ft. lbs.)





3. MEASURE TORQUE CONVERTER SLEEVE RUNOUT
Temporarily mount the torque converter to the drive plate. Set up a dial indicator and measure the torque converter sleeve runout.
