●

When installing fluid cooler tube to transaxle assembly, assem-
ble the part with the tube aligned with the rib. 

●

When installing transaxle to the engine, attach the fixing bolts in
accordance with the following standard.

●

Align the positions of tightening nuts for drive plate with those of
the torque converter, and temporarily tighten the nuts. Then,
tighten the nuts with the specified torque.

CAUTION:

●

Do not reuse O-ring and copper washers.

●

When turning crankshaft, turn it clockwise as viewed
from the front of the engine.

●

When tightening the tightening nuts for the torque con-
verter after fixing the crankshaft pulley bolts, be sure to
confirm the tightening torque of the crankshaft pulley mounting bolts. Refer to 

EM-68, "INSTAL-

LATION"

 .

●

 After converter is installed to drive plate, rotate crankshaft several turns and check to be sure
that transaxle rotates freely without binding.

●

Install crankshaft position sensor (POS) sensor. Refer to 

EM-29, "Removal and Installation"

 .

●

After completing installation, check for fluid leakage, fluid level, and the positions of CVT. Refer to
