mension A between the transmission fitting part and the
converter fitting part of the drive plate.

(c)

Using vernier calipers and a straight edge, measure the
dimension B shown in the illustration and check that B is
greater than A measured in step (b).
Standard distance: A + 1 mm (0.04 in.) or more

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 the stator with a finger and ro-
tate it.

(c)

Check if it rotates smoothly when turned clockwise and
locks when turned counterclockwise.

If necessary, clean the converter clutch and retest the one–way
clutch.
Replace the converter clutch 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.
Maximum runout: 0.20 mm (0.0079 in.)

(b)

Check for damage to the ring gear.

If runout is not within the specification or if the ring gear is dam-
aged, replace the drive plate. If installing a new drive plate, note
the orientation of the spacers and tighten the bolts (See page

EM–83

 or 

EM–95

).
