Do not remove engine until exhaust system has com-
pletely cooled off, otherwise, you may burn yourself
and/or fire may break out in fuel line.

Before disconnecting fuel hose, release pressure.
Refer to EC-43, “Fuel Pressure Release”.

Be sure to lift engine and transaxle in a safe manner.

For engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG.

CAUTION:

and brake master cylinder.

When lifting the engine, always use engine slingers in a
safe manner.

where,
D: Bored diameter
A: Piston diameter as measured
B: Piston-to-bore clearance
C: Honing allowance 0.02 mm (0.0008 in)

Install main bearing caps and tighten bolts to the specified
torque. This will prevent distortion of cylinder bores.

Cut cylinder bores.

When any cylinder needs boring, all other cylinders must
also be bored.

Do not cut too much out of cylinder bore at a time. Cut
only 0.05 mm (0.0020 in) or so at a time.

Hone cylinders to obtain specified piston-to-bore clearance.
