REMOVAL SERVICE POINTS

<<A>> FUEL HIGH-PRESSURE HOSE DISCONNECTION

1.Remove the fuel high-pressure hose stopper.

2.Remove the fuel high-pressure hose in the direction shown in the figure while the retainer is pulled up.
note If the retainer is released, install it after removing the fuel high-pressure hose.

<<B>> ENGINE MOUNTING BRACKET REMOVAL
1.
caution When supporting the engine and transmission assembly with a garage jack, be careful not to deform the engine oil pan.
Place a garage jack against the engine oil pan with a piece of wood in between to support the engine assembly.


2.Remove the special tool engine hanger (MB991895 or MB991928) for supporting the engine which were installed when removing the transmission assembly.

3.The installation position at the right bank side of special tool engine hanger balancer (MB991454) for supporting the engine installed when removing the transmission assembly has been changed from special tool engine hanger plate A (MB992208) (Right bank) to engine right hanger, and support the engine assembly using the chain block or others.
4.Loosen the engine mounting bracket mounting nuts and bolt, and remove the engine mounting bracket.

<<C>> ENGINE ASSEMBLY REMOVAL
After checking that all cables, hoses and wiring harness connectors and so on are disconnected from the engine, lift the chain block slowly to remove the engine assembly upward from the engine compartment.

INSTALLATION SERVICE POINTS

>>A<< ENGINE ASSEMBLY/ENGINE MOUNTING BRACKET INSTALLATION

1.Install the engine assembly, being careful not to pinch the cables, hoses or wiring harness connectors.
2.
caution When supporting the engine and transmission assembly with a garage jack, be careful not to deform the engine oil pan.
Place a garage jack against the engine oil pan with a piece of wood in between to support the engine assembly.


3.Remove the chain block or others and install the special tool engine hanger (MB991895 or MB991928) (Refer to GROUP 23C - Transmission Assembly ).
At this time, contrary to the removal, the installation position at the right bank side of special tool engine hanger balancer (MB991454) for supporting the engine has been changed from engine right hanger to special tool engine hanger plate A (MB992208) (Right bank).

>>B<< FUEL HIGH-PRESSURE HOSE CONNECTION
caution After connecting the fuel high-pressure hose, slightly pull it to ensure that it is installed securely. Also confirm that there is a play approximately 3 mm. Then install the stopper securely.


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