CAUTION:
Do not disassemble drive plate.
Never 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.
3. 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 (441 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-19, "INTAKE MANIFOLD COLLECTOR" .
–Remove intake manifold. Refer to EM-24, "INTAKE MANIFOLD" .
–Remove fuel injector and fuel tube assembly. Refer to EM-45, "FUEL INJECTOR AND FUEL TUBE" .
–Remove ignition coil. Refer to EM-42, "IGNITION COIL" .
–Remove rocker cover. Refer to EM-51, "ROCKER COVER" .
–Remove exhaust manifold. Refer to EM-26, "EXHAUST MANIFOLD" .
–Other removable brackets.
NOTE:
The figure shows an example of widely use engine stand that
can hold mating surface of transmission with drive plate
removed.
CAUTION:
Before removing the hanging chains, make sure the
engine stand is stable and there is no risk of overturning.
4. Drain engine oil. Refer to LU-9, "
Changing Engine Oil" .
