TORQUE CONVERTER CLUTCH
AND DRIVE PLATE
INSPECTION
1. INSPECT ONE±WAY CLUTCH
(a) Install SST so that it fits in the notch of the converter hub
and outer race of the one±way clutch.
SST 09350±30020 (09351±32020)
(b) Press on the serrations of stater with a finger and rotate
it.
Check if it rotates smoothly when turned clockwise and
locks up when turned counterclockwise.
2. MEASURE DRIVE PLATE RUNOUT AND INSPECT
RING GEAR
Set up a dial indicator and measure the drive plate runout.
Maximum runout: 0.20 mm (0.0079 in.)
If runout exceeds 0.20 mm (0.0079 in.) or if the ring gear is dam-
aged, replace the drive plate. If installing a new drive plate, note
the orientation of spacers and tighten the bolts.
Torque: 83 N´m (850 kgf´cm, 61 ft´lbf)
3. MEASURE TORQUE CONVERTER CLUTCH SLEEVE
RUNOUT
(a) Temporarily mount the torque converter clutch to the drive
plate. Set up a dial indictor.
Maximum runout: 0.30 mm (0.0118 in.)
If runout exceeds 0.30 mm (0.0118 in.), try to correct by reori-
enting the installation of the torque converter clutch.
If excessive runout cannot be corrected, replace the torque
converter clutch.
