a. Apply compressed air into oil hole of transaxle case at the loca-
tion as shown in the figure.
b. Check to see that retaining plate moves to snap ring.
c. If retaining plate does not contact snap ring:
• D-ring might be damaged.
• Seal lip might be damaged.
2. Remove snap ring (1) using a flat-bladed screwdriver A.
3. Remove retaining plates, drive plates, driven plates, dish plates.
4. Set Tool A on spring retainer assembly, and remove snap ring
from transaxle case while compressing spring retainer assem-
bly.
CAUTION:
Set SST directly over return springs.
5. Remove spring retainer assembly from transaxle case.
CAUTION:
Do not remove return springs from spring retainer.
6. Apply compressed air into the oil hole on transaxle case as
shown in the figure to raise piston while strongly pressing the
whole low & reverse brake piston by hand. When applying com-
pressed air, strongly press the whole piston and adjust the pres-
sure so that it is raised evenly. Portion (A) (low & reverse brake
pressure) especially tends to tilt.
CAUTION:
