WARNING:

• Situate the vehicle on a flat and solid surface.
• Place chocks at the front and back of rear wheels.
• For engines not equipped with engine slingers, attach proper slingers and bolts described in PARTS

CATALOG.

CAUTION:

• Always be careful to work safely, and avoid forceful or uninstructed operations.
• Never start working until exhaust system and engine coolant are cool enough.
• If items or work required are not covered by the engine section, refer to the applicable sections.
• Always use the support point specified for lifting.
• Use either 2-pole lift type or separate type lift as much as possible. If board-on type is used for

unavoidable reasons, support at rear axle jacking point with transmission jack or similar tool before
starting work, in preparation for the backward shift of the center of gravity.

• Confirm there is no interference with the vehicle.
• Check that all connection points have been disconnected.
• Keep in mind that the center of gravity of the vehicle changes. If necessary, use jack(s) to sup-

port the vehicle at rear jacking point(s) to prevent it from falling off the lift.

Separation Work

vice tool) (A) from the front and rear engine slingers to hoist
engine and flywheel housing assembly.
• For the flywheel housing side, use a webbing slinger (B) or an

equivalent to hoist the assembly horizontally.

CAUTION:

Always hoist the engine by using a two-point engine lifter
(i.e. hoisting the front and rear slingers from one point in
the air), or the rocker cover and parts around the engine
may be damaged due to the fall of the engine slinger.

3.

Remove power steering oil pump from engine side. Refer to 

ST-41, "VK50VE : Exploded View"

.

4.

Remove engine mounting insulators (RH and LH) under side nuts with power tool.

5.

Lift with hoist and separate the engine, transmission, transfer and front final drive assembly from front
suspension member.

CAUTION:

• Before and during this lifting, always check that any harnesses are left connected.
• Never damage engine mounting insulator and avoid oil/grease smearing or spills onto engine

mounting insulator.

6.

Remove alternator. Refer to 

CHG-32, "VK50VE : Exploded View"

.

7.

Separate the engine from the transmission assembly. Refer to
