NOTICE:
- Stop the press when the spring seat is lowered 1 to 2 mm (0.0393 to 0.0787 in.) from the snap ring groove. This prevents the spring seat from being deformed.
- Do not expand the snap ring excessively.





(c) Remove the clutch balancer from the input shaft.





(d) Remove the forward clutch return spring from the input shaft.
39. REMOVE FORWARD CLUTCH PISTON SUB-ASSEMBLY





(a) Place the input shaft drum onto the oil pump.
(b) Holding the forward clutch piston by hand, apply compressed air (392 kPa, 4.0 kgf/cm2, 57 psi) to the oil pump to remove the forward clutch piston.
HINT: If the piston is slanted and cannot be removed, either blow air again with the protruding side pushed, or remove the piston using needle nose pliers with the tips taped.

40. REMOVE INPUT SHAFT OIL SEAL RING





(a) Remove the input shaft oil seal ring from the input shaft.
41. REMOVE MULTIPLE DISC CLUTCH HUB





(a) Remove the thrust needle roller bearing, multiple disc clutch hub, thrust needle roller bearing and No. 1 thrust bearing race from the transaxle case.
42. INSPECT MULTIPLE DISC CLUTCH HUB Transaxle Unit
43. REMOVE UNDERDRIVE PLANETARY GEAR ASSEMBLY





(a) Remove the bolt and pawl shaft clamp from the transaxle case.





(b) Remove the parking lock pawl shaft from the transaxle case.





(c) Push the parking lock pawl.
HINT: Failure to do so will cause interference when the underdrive planetary gear is removed.





(d) Remove the underdrive planetary gear assembly from the transaxle case.
NOTE: Do not drop the underdrive planetary gear assembly.

44. REMOVE FRONT PLANETARY GEAR NUT

SST: 09950-00020
SST: 09950-00030
SST: 09950-40011
09957-04010
SST: 09950-60010
09951-00320
47. REMOVE UNDERDRIVE PLANETARY RING GEAR





(a) Using snap ring pliers, remove the snap ring.





(b) Remove the underdrive planetary ring gear from the counter driven gear.
48. REMOVE PARKING LOCK PAWL
