Removal Work
1.
Use a manual lift table caddy (commercial service tool) or equiv-
alently rigid tool such as a transmission jack. Securely support
bottom of suspension member and transmission.
CAUTION:
Put a piece of wood or something similar as the supporting
surface, secure a completely stable condition.
2.
Remove rear engine mounting member bolts.
3.
Remove front suspension member mounting bolts and nuts. Refer to
.
4.
Carefully lower jack, or raise lift to remove the engine, transmission assembly, transfer, front final drive
assembly and front suspension member. When performing work, observe the following caution:
CAUTION:
• Confirm there is no interference with the vehicle.
• Make sure that all connection points have been disconnected.
• Keep in mind the center of the vehicle gravity changes. If necessary, use jack(s) to support the
vehicle at rear jacking point(s) to prevent it from falling it off the lift.

1.
Install engine slingers into front of cylinder head (right bank) and
rear of cylinder head (left bank).
• To protect rocker cover against damage caused by tilting of
engine slinger, insert spacer between cylinder head and
engine rear lower slinger (3), in direction shown in the figure.
NOTE:
Spacer (2) is a component part of engine rear upper slinger
assembly.
2.
Remove power steering oil pump from engine side. Refer to
44, "WITHOUT 4WAS : Exploded View"
(without 4WAS) or
49, "WITH 4WAS : Exploded View"
(with 4WAS).
3.
Remove engine mounting insulators (RH and LH) under side nuts with power tool.
4.
Lift with hoist and separate the engine, the transmission assembly, the transfer assembly and the front
final drive assembly from front suspension member.
CAUTION:
• Before and during this lifting, always check if any harnesses are left connected.
• Avoid damage to and oil/grease smearing or spills onto engine mounting insulator.
5.
Remove alternator. Refer to
.
6.

- Temporarily tighten mounting bolts [shown as (D), (E) and (F) in
the figure].
- Tighten mounting bolts to the specified torque with following
mounting surfaces touched.
• Engine mounting bracket (RH) (1) to engine mounting bracket
(RH) (lower) [shown as and in figure].
• Front final drive to engine mounting bracket (RH) (lower) [shown
as in figure].

INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to
MA-10, "Fluids and Lubricants"
.
• Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids includ-
ing engine oil and engine coolant.
• Bleed air from lines and hoses of applicable lines, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
