Precaution for Removal and DisassemblyINFOID:0000000005930915
• When instructed to use special service tools, use the spec
ified tools. Always be careful to work safely, avoid
forceful or uninstructed operations.
• Exercise maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or the equiva lent, if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally opposite, and so on. If the order of loosening is specif ied, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000005930916
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000005930917
• Use torque wrench to tighten bolts or nuts to specification.
• When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
do exactly as specified.
• Replace with new gasket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.
• Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust. Before assembly, oil sliding surfaces well.
• Release air within route after draining coolant.
• Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped).
Then make sure that there are no leaks at fuel line connections.
• After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for
leakage.
Parts Requiring Angular TighteningINFOID:0000000005930918
• Use an angle wrench for the final tightening of the following engine parts:
- Cylinder head bolts
- Camshaft sprocket (INT)
- Main bearing cap bolts
- Connecting rod cap nuts
- Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angulartightening)
• Do not use a torque value for final tightening.
• The torque value for these parts are for a preliminary step.
• Ensure thread and seat surfaces are clean and coated with engine oil.

3. Remove flywheel or driveplate. • Secure flywheel or driveplate with Tool, and remove bolts.
CAUTION:
• Never disassemble flywheel.
• Never place flywheel or driveplate with signal plate facing down.
• 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-27, "
Exploded View".
- Exhaust manifold: Refer to EM-30, "
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".
