Pistons

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.

INCORRECT

CORRECT

RUBBER HOSES

Remove the connecting rod caps, then slip the

long rubber hoses over the threaded ends of the

connecting rod bolts.

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 pushing the piston into place.

Install the rod caps with bearings, and torque the

nuts to 44 N-m (4.5 kgf-m, 33 Ibf-ft).
2. 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 right side

of the engine.

CONNECTING ROD

OIL HOLE

RUBBER

HOSE

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.

Pistons

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:

Remove the connecting rod caps and slip short

sections of rubber hose over the threaded ends

of the connecting rod bolts.

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 tapping after the ring compressor pops

free, and check the connecting rod-to-crank jour-

nal alignment before pushing piston into place.

Install the rod caps with bearings, and torque the

nuts to 32 N-m (3.3 kgf-m, 24 Ibf-ft)

2. 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.

Position all pistons at top dead center.

The arrow must face

the timing belt side

of the engine and the

connecting rod oil hole

must face the intake

manifold.
