U140F AUTOMATIC TRANSAXLE: UNDERDRIVE CLUTCH: INSTALLATION

1. INSTALL UNDERDRIVE CLUTCH PISTON SET

(a) Coat the underdrive clutch piston with ATF, and install it to the underdrive clutch piston drum.

NOTICE:
Be careful not to damage the O-ring.

(b) Install the piston return spring to the underdrive clutch drum.

NOTICE:
Be careful not to damage the lip seal of the clutch balancer.

(d) Place SST on the clutch balancer and compress the piston return spring with a press.

SST : 09350-32014

09351-32070

(e) Using a snap ring expander, install the snap ring to the underdrive clutch drum.

NOTICE:
* Be sure the end gap of the snap ring is not aligned with the clutch balancer's claw.
* Stop the press when the spring sheet is lowered to a position 1 to 2 mm (0.039 0.078 in.) from the snap ring groove.
* This prevents the spring sheet from being deformed.
* Do not expand the snap ring excessively.

(f) Set the end gap of the snap ring in the underdrive clutch drum shown in the illustration.

NOTICE:
The end gap of the snap ring should not coincide with any of the stopper.

2. INSTALL UNDERDRIVE CLUTCH DRUM O-RING

(a) Coat the new O-ring with ATF, and install it to the underdrive clutch drum.

3. INSTALL NO. 1 UNDERDRIVE CLUTCH DISC

(a) Install the 3 plates, 3 discs and flange to the underdrive clutch drum.

Install in order:

P - D - P - D - P - D - F

HINT
P = Plate

D = Disc

F = Flange

(b) Using a screwdriver, install the underdrive clutch flange hole snap ring.

(c) Check that the end gap of the snap ring is not aligned with one of the cutouts.

4. INSPECT UNDERDRIVE CLUTCH PACK CLEARANCE

(a) Install the underdrive clutch to the transaxle.

Be careful not to damage the oil seal rings.

(b) Set a dial indicator as shown in the illustration.

(c) Measure the underdrive clutch piston stroke while applying and releasing compressed air (392 kPa, 4.0 kgf/cm2, 57 psi).

Standard pack clearance:

1.51 to 1.90 mm (0.0594 to 0.0748 in.)

If the pack clearance is less than the minimum, parts may have been assembled incorrectly, so check and reassemble again.

If the park clearance is not as specified, select another flange.

HINT
There are 3 flanges in different thickness.

Standard flange thickness:
