NOTE:
Explained here is how to disassemble with engine stand s
upporting transmission surface. When using a differ-
ent type of engine stand, note the difference in the steps, etc.
1. Remove the engine assembly from the vehicle. Refer to EM-98, "
Exploded View".
2. Remove crankshaft pulley. Refer to EM-96, "
FRONT OIL SEAL : Removal and Installation".
NOTE:
The drive plate is fixed with a ring gear stopper [SST: KV10119200 (J-49277)]. 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 used engine stand.  Fix crankshaft with a ring gear stopper [SST: KV10119200 (J-49277)]. Loosen drive plate mounting bolt
with power tool.
 Check for deformation or damage of drive plate. Refer to EM-115, "
Inspection".
NOTE:
The procedure is described assuming that you us e a widely used engine stand holding the surface, to
which transmission is installed.
4. Remove pilot converter using the pilot bushing puller (commercial service tool), if necessary.
5. Lift the engine with hoist to inst all it onto the widely used engine stand.
CAUTION:
Use an engine stand that has a load capacity [240 kg (529 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. Refer to EM-30, "
Exploded View".
- Remove fuel injector and fuel tube assembly. Refer to EM-48, "
Exploded View".
- Remove ignition coil. Refer to EM-29, "
Exploded View".
- Remove rocker cover. Refer to EM-33, "
Exploded View".
- Remove exhaust manifold. Refer to EM-40, "
Exploded View".
- Other removable brackets. NOTE:
The figure shows an example of widely used engine stand (A)
that can hold mating surface of transmission with drive plate
removed.
CAUTION:
Before removing the hang ing chains, check the engine
stand is stable and there is no risk of overturning.
6. Drain engine oil. Refer to LU-8, "
Draining".
