Piston/Connecting Rod Assemblies
Installation
Before installing the piston, apply a coat of
engine oil to the ring grooves and cylinder
bores.
1. If the crankshaft is already installed:
• Guide the piston carefully to prevent damage.
• Fit long rubber hoses (about 30 cm (12 in) long) to
the connecting rod bolts to protect the crankshaft.
• Install the pistons after setting the crankshaft to
BDC for each cylinder.
CORRECT INCORRECT
RUBBER HOSES
Install the piston assemblies in No. 1 and No. 4
cylinders, No. 2 and No. 5 cylinders, and No. 3
and No. 6 cylinders.
Install the ring compressor, check that the bear-
ing is securely in place; then position the piston
in the cylinder and tap it in using the wooden
handle of a hammer.
Stop after the ring compressor pops free and
check the connecting rod-to-crank journal align-
ment before putting rod into place.
Install the rod caps with bearings, and torque the
nuts to 20 N-m (2.0 kg-m, 14 Ib-ft), then turn the
nut 95 degrees (see page 7-19).
If the crankshaft is not installed:
• Remove the rod caps and bearings, install the
ring compressor, then position the piston in the
cylinder and tap it in using the wooden handle of
a hammer.
The arrow must face
the timing belt side
of the engine and the
connecting rod oil hole
must face the rear side
of the engine.

OIL HOLE
NOTE: Maintain downward force on the ring com-
pressor to prevent rings from expanding before
entering the cylinder bore.
Use the wooden handle
of a hammer to push, or
tap the piston into the
cylinder bore.
