20. Carefully lower transmission jacks in accordance with the low-
ering pace of the hoist, and remove engine and transaxle
assembly from vehicle.
+While working, check that no parts of engine assembly
interfere with adjacent parts on the vehicle.
+While working, make sure that parts requiring disconnec-
tion are not left connected, and that no parts interfere with
vehicle.
+To prevent vehicle from falling down, perform operation
carefully so that the center of gravity of the vehicle will not
shift.
21. Remove center member.
+Before starting removal operation, first place the assem-
bly on a level surface and securely support the bottom
surface with wood blocks. Using a hoist, lift engine
slingers, and make sure the assembly is stable.
22. Separate engine and transaxle.
INSTALLATIONNJEM0069S02Install in the reverse order of removal, observing the following:
+While installing, be careful to keep mount insulators free of oil
smear and damage.
+When parts require specified installation directions/positions,
install by using the identifying marks indicating up or front.
+While keeping the mount insulators free of twists or distortions,
start tightening from the through-bolt on the engine mount
insulator LH. This mount is used as the reference position.
