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 mu st make sure any dowels are installed correctly
during re-assembly.
• Improper alignment caused by missing dowels m ay 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-160 .
• After converter is installed to drive plate, ro tate crankshaft several turns to check that transaxle
