U241E AUTOMATIC TRANSAXLE: UNDERDRIVE CLUTCH: DISASSEMBLY

DISASSEMBLY

1. INSPECT PACK CLEARANCE OF UNDERDRIVE CLUTCH

(a) Install the underdrive clutch into the transaxle case.
NOTE: Be careful not to damage the oil seal rings.

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

(c) Measure the underdrive clutch pack clearance while applying and releasing compressed air (392 kPa, 4.0 kgf/cm2, 57 psi).
Standard pack clearance:
1.51 to 1.71 mm (0.0595 to 0.0673 in.)
If the pack clearance is not as specified, inspect the discs, plates and flange.
2. REMOVE NO. 1 UNDERDRIVE CLUTCH DISC

(a) Using a screwdriver, pry out the snap ring.

(b) Remove the flange, 3 discs and 3 plates from the underdrive clutch drum.
3. REMOVE UNDERDRIVE CLUTCH PISTON SET

(a) Place SST on the clutch balancer and compress the spring with a press.
SST: 09350-32014
09351-32070
(b) Using a snap ring expander, remove the snap ring.
NOTICE:
- Stop the press when the spring sheet is lowered to the place 1 to 2 mm (0.039 to 0.078 in.) from the snap ring groove.
- This prevents the spring sheet from being deformed.
- Do not expand the snap ring excessively.

(d) Install the underdrive clutch into the transaxle case.
NOTE: Be careful not to damage the oil seal rings.

(e) Holding the underdrive clutch drum with your hand, apply compressed air (392 kPa, 4.0 kgf/cm2, 57 psi) to the oil hole and remove the underdrive clutch piston.
- Applying the air may cause the piston to jump out. When removing the piston, hold it using a piece of cloth.
- Do not splash ATF with the compressed air.

(f) Remove the O-ring from the underdrive clutch drum.
