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 the engine assembly from the vehicle. Refer to 

EM-82, "2WD : Exploded View"

 (2WD models) or

EM-87, "AWD : Exploded View"

 (AWD models).

2.

Remove crankshaft pulley. Refer to 

EM-53, "Exploded View"

.

NOTE:
The drive plate is fixed with a ring gear stopper [SST: KV10118600 (J-48641)]. Loosen the crankshaft pul-
ley mounting bolts before installing the engine stand.

3.

Remove the parts that may restrict installation of engine to a widely use engine stand.
• Fix crankshaft with a ring gear stopper [SST: KV10118600 (J-48641)]. Loosen drive plate mounting bolt

with power tool.

• Check for deformation or damage of drive plate. Refer to 

EM-117, "Exploded View"

.

NOTE:
The procedure is described assuming that you use a widely use engine stand holding the surface, to
which transmission is installed.

4.

Remove pilot converter using the pilot bushing puller [SST:
ST16610001 (J-23907)] (A), if necessary.

5.

Lift the engine with hoist to install it onto the widely use engine stand.

CAUTION:

Use an engine stand that has a load capacity [220 kg (485 lb) or more] large enough for supporting
the engine weight. 
• If the load capacity of the stand is not adequate, remove the following parts beforehand to reduce the

potential risk of overturning the stand.

- Remove intake manifold collector. Refer to 

EM-31, "Exploded View"

. 

- Remove intake manifold. Refer to 

EM-34, "Exploded View"

.

- Remove fuel injector and fuel tube assembly. Refer to 

EM-40, "Exploded View"

.

- Remove ignition coil and rocker cover. Refer to 

EM-50, "Exploded View"

.

- Remove exhaust manifold. Refer to 

EM-36, "Exploded View"

.

- Other removable brackets.

NOTE:
The figure shows an example of widely use engine stand (A)
that can hold mating surface of transmission with drive plate
removed.

CAUTION:

Before removing the hanging chains, check the engine
stand is stable and there is no risk of overturning.
