WARNING:
 Situate vehicle on a flat and solid surface.
 Place chocks at front and back of rear wheels.
 For engines not equipped with engi ne slingers, attach proper slingers and bolts described in PARTS
CATALOG.
CAUTION:
 Always be careful to work safely, avoid forceful or uninstructed operations.
 Do not start working until exhaust system and engine coolant are cool enough.
 If items or work required are not covered by th e engine section, refer to the applicable sections.
 Always use the support poin t specified for lifting.
 Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at the rear axle jacking poin t with transmission jack or similar tool before
starting work, in prepar ation for the backward shif t of center of gravity.
 For supporting points fo r lifting and jacking point at rear axle, refer to GI-37, "
Garage Jack and
Safety Stand".

10. Disconnect steering lower joint at power steering gear
assembly side, and release steering lower shaft.
Refer to PS-12, "
Removal and Installation".
11. Remove rear propeller shaft. Refer to PR-7, "
On-Vehicle Inspection".
 After disconnection, plug the opening on transmission side.
12. Remove front drive shaft (both side). Refer to FAX-13, "
On-Vehicle Inspection".
13. Remove front propeller shaft. Refer to PR-4, "
On-Vehicle Inspection".
14. Remove three way catalyst (both bank). Refer to EM-179, "
Component".
Removal Work
1. Install engine slingers into front of cylinder head (left bank) and
front of cylinder head (right bank).
2. Lift with hoist and secure engine in position.
3. Use manual lift table caddy (commercial service tool) or equivalently rigid tool such as 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.
4. Remove engine rear member mounting bolts.
5. Remove front suspension member mounting nuts with power tool. Refer to FSU-5, "
On-Vehicle Inspection
and Service".
6. Carefully lower jack, or raise lift to remove engine, transmission front final drive and front suspension member assembly. When
performing work, observe the following caution:
CAUTION:
 Confirm there is no interference with vehicle.
 Make sure that all connectio n points have been discon-
nected.
 Keep in mind the center of veh icle gravity changes. If nec-
essary, use jack(s) to support vehicle at rear jacking
point(s) to prevent it from falling it off the lift.
Separation Work
1. Change engine slinger installing to cylinder head (right bank).
NOTE:
In order to keep secure position when hoisting engine.
2. Remove engine mounting insulators (RH and LH) under side nut with power tool.
3. Lift with hoist and separate engine and transmission assembly from front suspension member. CAUTION:
 Before and during this lifting, always make sure that any harnesses are left connected.

DISASSEMBLY
NOTE:
Explained here is how to disassemble with engine stand supporting transmission surface. When using differ-
ent type of engine stand, note with difference in steps and etc.
1. Remove engine assembly from vehicle, and separa te front suspension member, transmission and front
final drive from engine. Refer to EM-237, "
Component".
2. Remove the parts that may restrict installation of engine to widely use engine stand. NOTE:
The procedure is described assuming that you use wi dely use engine holding the surface, to which trans-
mission is installed.
a. Remove drive plate.  Holding ring gear with ring gear stopper (SST).
 Loosen mounting bolts diagonally order.
CAUTION:
 Do not disassemble drive plate.
 Do not place drive plate with signal plate facing down.
 When handling signal plate, take care not to damage or scratch it.
 Handle signal plate in a manner that prevents it from becoming magnetized.
b. Remove engine rear plate.
3. Lift engine with hoist to install it onto widely use engine stand. CAUTION:
Use engine stand that has a load capacity [approximately 240 kg ( 529 lb) or more] large enough for
supporting the engine weight.
 If the load capacity of stand is not adequate, remo ve the following parts beforehand to reduce the poten-
tial risk of overturning stand.
- Intake manifolds (upper and lower): Refer to EM-175, "
Component".
- Exhaust manifold: Refer to EM-179, "
Component".
- Fuel tube and fuel injector assembly: Refer to EM-190, "
Component".
