c. Place mating surface of valve body face down, and remove
internal parts.
CAUTION:

If a valve is hard to remove, place valve body face down
and lightly tap it with a soft hammer.

Be careful not to drop or damage valves and sleeves.
INSPECTION
Valve Springs

Check each valve spring for damage or deformation. Also mea-
sure free length and outer diameter. Refer to AT - 3 8 0 , "
Control
Va l v e s" .

Replace valve springs if deformed or fatigued.
Control Valves
Check sliding surfaces of valves, sleeves and plugs. Replace if necessary.
ASSEMBLY
CAUTION:

Apply ATF to all components before installation.

Lay control valve body down when installing valves. Do not
stand control valve body upright.
Lubricate control valve body and all valves with ATF. Install control
valves by sliding them carefully into their bores.
CAUTION:

Install each control valve one by one.

Install control valves after checking, because some of them
are similar.

Be careful not to scratch or damage valve body.

e. Attach dial indicator on differential case at converter housing
side.
f. Insert SST into differential side gear from transaxle case side.
g. Move SST up and down and measure dial indicator deflection.
h. Select proper thickness of differential side bearing adjusting
shim. Refer to “Parts Information” for differential side bearing
adjusting shim selection.
Suitable shim thickness = Dial indicator deflection + Speci-
fied bearing preload
i. Remove converter housing from transaxle case.
j. Remove final drive assembly from transaxle case.
k. Remove differential side bearing outer race from transaxle case.
l. Reinstall differential side bearing outer race and differential side
bearing adjusting shim selected from “Parts Information” on
transaxle case.
m. Reinstall converter housing on transaxle case and tighten con-
verter housing mounting bolts to the specified torque. Refer to
AT-257, "
Components" .
n. Insert SST and measure turning torque of final drive assembly.

Turn final drive assembly in both directions several times
to seat bearing rollers correctly.

When old bearing is used again, turning torque will be
slightly less than the above.

Make sure torque is close to the specified range.Suitable shim thickness = Dial indicator deflection +
Specified bearing preload
