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.

NOTE:

• Use liquid gasket, Part No. 08718 - 0001 or 08718

- 0003.

• Check that the mating surfaces are clean and dry

before applying liquid gasket.

• Apply liquid gasket evenly, being careful to cover

all the mating surface.

• To prevent oil leakage, apply liquid gasket to the

inner threads of the bolt holes.

• Do not apply liquid gasket to O-ring grooves.

• Do not install the parts if five minutes or more

have elapsed since applying liquid gasket.

Instead reapply liquid gasket after removing old

residue.

• After assembly, wait at least 30 minutes before

filling the engine with oil.

Apply liquid gasket

along the broken line.
