1. Place a cart below the engine and transmission

assembly.

2. Lower the lift to the position where the weight of

the engine and transmission assembly is not
applied to the transmission mounting insulator
and the engine mounting insulator.

3. Remove the self-locking nuts, transmission

mounting insulator mounting bolt and engine
mounting insulator mounting bolts.

CAUTION

Because the engine assembly is installed with
tilted toward the rear side, support the engine
and transmission assembly after removing the
engine mounting insulator.
4. Remove the engine mounting insulator.

<<E>> ENGINE AND TRANSMISSION
ASSEMBLY REMOVAL

1. Confirm that the cable, the hose, and the harness

connector are all disconnected.

CAUTION

Do not bend the fuel high-pressure hose.
2. Raise the body slowly with a lift, and remove the

engine and transmission assembly.

1. Install the chain of special tool engine hanger

balancer (MB991454) and special tool engine
hanger (MB991527), and set the chain block.

2. Remove the transmission assembly connecting

bolts.

CAUTION

When lifting the engine assembly, operate

with care not to lift the transmission assem-
bly.

When working, make sure that the torque

converter will not be detached with the
engine.

3. Lift the engine assembly slowly using the chain

block, and remove the transmission assembly
when the engine assembly is lifted a little.

1. Place the engine and transmission assembly on

the cart below the lifted vehicle.

2. Lower the lift to the position where the mounting

bolts of the engine mounting insulator and the
transmission mounting insulator, and the
self-locking nuts are installed.

3. Install the engine mounting insulator.
4. Tighten the new self-locking nuts of engine

mounting insulator and transmission mounting
insulator to the specified torque, and tighten the
new mounting bolts of engine mounting insulator
and transmission mounting insulator to the
specified torque.

Tightening torque:

± 7 Nm <Engine mounting insulator mount-

ing bolts and self locking nuts>

63

± 7 Nm <Transmission mounting insulator

mounting bolt and self locking nuts>

>>C<< FUEL HIGH-PRESSURE HOSE
INSTALLATION

AC208465AE

3 mm

Fuel high-pressure hose

Fuel delivery pipe

CAUTION

After connecting the fuel high-pressure hose,

check that it has been securely installed by
slightly pulling in the removal direction. At
this time, also check that there is approxi-
mately 3-mm play.

When applying the engine oil, make sure not

to allow the engine oil to enter the fuel deliv-
ery pipe.

Apply a small amount of the engine oil to the fuel
delivery pipe, and then install the fuel
high-pressure hose.

>>D<< INITIALISATION

When the engine-CVT-ECU is removed, initialise the
electronic-controlled throttle valve system according
to the following procedure after installing the
engine-CVT-ECU.

Turn the ignition switch from "ON" position to
"LOCK" (OFF) position, and then hold "LOCK"
(OFF) position for approximately 10 seconds or
more.
