3. Stop after the ring compressor pops free, and check

the connecting rod-to-crank journal alignment

before pushing the piston into place.

4. Install the rod caps with bearings, and torque the

nuts to 44 N-m (4.5 kgf-m, 33 Ibf-ft).
RUBBER HOSES

Pistons

Installation

Before installing the piston, apply a coat of engine

oil to the ring grooves and cylinder bores.

1. Install the ring compressor, check that the bearing

is securely in place; then position the piston in the

cylinder and tap it in using the wooden handle of a

hammer.

2. Install the piston/connecting rod assemblies in the

cylinder block.

• 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 crank-

shaft.

• Install the pistons after setting the crankshaft to

BDC for each cylinder.

INCORRECT
The arrow must face

the timing belt side

of the engine and the

connecting rod oil hole

must face the right side

of the engine.

HOSE

NOTE: Maintain downward force on the ring com-

pressor to prevent the 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.
