When installing water hoses, install them according to the following:
• Insert CVT water hose according to dimension “A” described
below.
• Set hose clamps (1) at the both ends of fluid cooler hose (2) with dimension (A) from the hose edge.
• Hose clamp should not interfere with the bulge.
*: Refer to the illustrations for the specific position of each hose clamp tab.
• The illustrations indicate the view from the hose ends.
• When installing hose clamps the center line of each clamp tab should be positioned as shown.

2. Disconnect the primary speed sensor (A) and the secondary
speed sensor connector (B) and CVT unit connector (C). Refer
to CVT-9, "
Removal and Installation Procedure for CVT Unit
Connector".
3. Remove the harness from the transaxle.
4. Remove the four drive plate to torque converter nuts. NOTE:
Rotate the crankshaft clockwise as viewed from front of engine
for access to drive plate to torque converter nuts.
5. Put matching marks on the drive plate and torque converter alignment stud. CAUTION:
For matching marks, use paint. Never dama ge the drive plate or torque converter.
6. Remove the transaxle to engine and engine to transaxle bolts.
7. Separate the transaxle from the engine.
8. If necessary, remove the following from the transaxle: • CVT fluid charging pipe
• Engine mounting bracket (LH)
• Fluid cooler tubes
• Air breather hose
• Any necessary brackets
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• When replacing an engine or transmission you must make sure any dowels are installed correctlyduring re-assembly.
• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive train components.
• Do not reuse O-rings and copper washers.
• When turning crankshaft, turn it clockwise as viewed from the front of the engine.
• When tightening the nuts for the torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-159
.
• After converter is installed to drive plate, ro tate crankshaft several turns to check that transaxle
rotates freely without binding.

TRANSAXLE ASSEMBLY
• When installing the torque converter to the transaxle measure dis-
tance A.
• When installing the cooler outlet tube (1) to the transaxle assembly (2), align the cooler tube bracket (A) against the transaxle as
shown.
• When installing the transaxle to the engine, align t he matching mark on the drive plate with the matching
mark on the torque converter alignment stud.
• When securing the transaxle to the engine, attach the bolts in accordance with the following standard.
• When installing the drive plate to torque converter nuts, tighten them temporarily. Then tighten the nuts to the specified torque.
• After completing installation check for fluid level, fluid leakage, and the positions of CVT. Refer to CVT-14,
"Checking CVT Fluid", CVT-164, "Adjustment of CVT Position" and CVT-164, "Checking of CVT Position".
• When replacing the CVT assembly, erase EEP ROM in TCM. Refer to CVT-8, "
Service After Replacing TCM
and Transaxle Assembly".
