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 and the transaxle assembly from the vehicle, and separate the transaxle from the
engine. Refer to EM-89, "
Exploded View".
2. Remove clutch cover and clutch disc. Refer to CL-13, "
Removal and Installation".
3. Remove flywheel.
 Secure flywheel with a stopper plate [SST: KV11105210], and remove mounting bolts.
CAUTION:
 Never disassemble flywheel.
 Never place flywheel 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.
4. Lift the engine with a hoist to install it onto widely use engine stand.
CAUTION:
 Use the engine stand that has a load capacity [approximately 135 kg (298 lb) or more] large
enough for supporting the engine weight.
 If the load capacity of stand is not adequate, remove the following parts beforehand to reduce the poten-
tial risk of overturning stand.
- Intake manifold: Refer to EM-29, "
Exploded View".
- Exhaust manifold: Refer to EM-32, "
Exploded View".
- Rocker cover: Refer to EM-47, "
Exploded View".
NOTE:
The figure shows an example of widely use engine stand that
can support mating surface of transaxle with flywheel removed.
CAUTION:
Before removing the hanging chains, make sure the engine
stand is stable and there is no risk of overturning.
5. Drain engine oil. Refer to LU-7, "
Draining".
6. Drain engine coolant by removing water drain plug (1) from
inside of the engine.
Use Genuine Liquid Gasket or equivalent.
