Transaxle Disassembly (Fig. 19)
1. Drain oil from transaxle. After draining, install and
torque drain plug from 16 to 19 ft−lb (21 to 25 N−m).
2. Clean the outside of the transaxle assembly.
3. Remove RH and LH axle case assemblies from
transaxle case assembly (Fig. 20):
A. For assembly purposes, mark axle case and
transaxle case before removing the axle case. The
right and left axle cases and axle shafts have differ-
ent lengths so correct assembly is critical.
B. Remove five (5) flange bolts that secure axle
case assembly to transaxle case.
C. Slide axle case assembly with installed axle shaft
from transaxle case.
D. Repeat process to remove second axle case as-
sembly.
4. Remove bolt (item 6 in Fig. 19) near the selector
shaft. Remove gasket, spring and steel ball from bore in
LH case. Gasket replacement is recommended during
assembly.
5. Separate transaxle cases (Fig. 21):
A. Support the transaxle case assembly with the in-
put shaft side (RH case side) down. Loosen and re-
move flange bolts that secure the cases together.
Note location of shorter flange bolt for assembly pur-
poses.
IMPORTANT: Do not use a pry bar or screw driv-
er on the transaxle case mating surfaces when
separating the transaxle cases. Damage to the
sealing surfaces of the cases may result.
B. Using bosses on cases as pry−points, separate
cases. Raise LH case leaving internal transaxle
components in RH case.
