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-88, " Exploded View " .

3. Remove flywheel or driveplate. • Secure flywheel or driveplate with Tool, and remove bolts.
CAUTION:
• Never disassemble flywheel.

• When handling signal plate, take car e 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-28, " Exploded View " .
- Exhaust manifold: Refer to EM-31, " Exploded View " .
- Rocker cover: Refer to EM-46, " Exploded View " .
NOTE:
The figure shows an example of widely use engine stand that
can support mating surface of transaxle with flywheel or drive-
plate 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-8, " Draining " .
6. Drain engine coolant by removing water drain plug (1) from RH side of the engine. Tool number : KV11105210 (J-44716)

CONNECTING ROD BEARING CRUSH HEIGHT
• When connecting rod bearing cap is removed after being tightened to the specified torque with connecting rod bearings installed, the
tip end of bearing must protrude. Refer to EM-96, " Disassembly
and Assembly " .
• If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER
• Measure the outer diameters (“d 1”, “d 2”) at two positions as shown.
• If reduction appears in a position other than “d 2 ”, regard it as “d 2”.
• If it exceeds the limit (a large difference in dimensions), replace main bearing cap bolt with a new one.
CONNECTING ROD CAP BOLT OUTER DIAMETER
• Measure the outer diameter “d” at position as shown.
• If reduction appears in a position other than “d”, regard it as “d”.
• When “d” falls below the limit (when it becomes thinner), replace connecting rod cap bolt with a new one.
FLYWHEEL DEFLECTION
• Measure the deflection of flywheel contact surface to clutch with a
dial indicator.
• If measured value is out of the standard, replace flywheel. Standard: There must be crush height. PBIC1646E
