9. Remove timing belt.

CAUTION:

D

Do not bend or twist belt, otherwise its core could
be damaged. The belt should not be bent at a
radius less than 30 mm.

D

Timing belt drive pulley counterhold with
J–42620.

D

Do not allow oil or other chemical substances to
come in contact with the belt. They will shorten
the life.

D

Do not attempt to pry or stretch the belt with a
screw driver or any other tool during installation.

D

Store timing belt in cool and dark place. Never
expose the belt direct sunlight or heat.

Installation

1. Install timing belt tensioner then tighten it temporarily

until make alignment timing belt.

2. Install the timing belt and perform timing belt setting

procedure as follows:
a. Bring the engine top dead center No.1 cylinder

compression stroke by rotating the engine in the
direction of normal operation.
If rotated too far, do not turn backwards, always
rotate crank in a clockwise direction otherwise
tensioner setting will not be corret.
The engine is in this position when the notches on
the camshaft pulleys align with the marks on the
cylinder head cover(1), Check the crankshaft
pulley timing mark is aligned (2).

b. Place J–43037 between intake and exhaust of

camshaft drive gear for prevent to camshaft drive
gear movement during timing belt setting.

c. Set the timing belt shown in the illustration, ensure

that tension side of the timing belt is taut and move
the timing belt tension adjustment lever clockwise,
until the pointer of the tensioner is flowing.

3. Adjust the timing belt tension.

Must be done with engine cold at least 8hr cool down.
Setting tensioner hot will result in incorrect tensioner
setting.
The timing belt tension adjusting procedure as
follows.
Per Setting

a. In the state that the tensioner bolt and timing belt

are loose, pointer (1) is anywhere to the left of
center V notch (Note: The tensioner adjuster (2) is
at the 7 o’clock position); Viewed from in front of the
engine or vehicle.

014R100034

b. Turn the tensioner adjuster (2) with wrench to

anticlockwise direction so that the pointer moves to
the right edge of the plate, the pointer (1) should
not pass the right hand edge of the plate during
installation.

014R100035

c. Tighten the tensioner bolt to 15 N·m (11 lb ft)(with

left hand) whilst keeping the adjuster in control
(with right hand).

014R100033

CAUTION: Check engine timing. All engine timing
marks (two camshaft pulley and crankshaft pulley)
must be aligned. If all three timing marks are not
aligned the timing belt must be removed and
reinstalled.

d. Remove the fixing tool J–43037.
e. Manual rotate the crankshaft two turns (720

°

)

clockwise so that marks in timing gear will align
again with the mark on cylinder head cover and all
three timing marks are aligned.
Remainder: If accidentally turn too far, do not turn
backward. Continue turn in the same direction.
Turning backwards will cause incorrect setting.

New Belt
Adjustment of the new timing belt.

a. Slightly loosen the fastening bolt of the timing belt

tension roller, depending on the version, rotate the
adjustment cam in direction of arrow (clockwise)
until:
Version 1: Pointer (1) of the timing belt tension
roller aligns with the notch (2).

b. Version 2: Pointer (1) of the timing belt tension

roller aligns with the “NEW” notch (2).

c. Tighten the fastening bolt (1) of the timing tension

roller.

Torque: 25 N·m (18 lb ft)

020RW010

d. Turn the crankshaft another two turns (720

°

) in

engine rotational direction to mark 1st cylinder
TDC and check adjustment of the timing belt
tension roller. Do not turn crankshaft anti
clockwise, this will result in incorrect tensioner
setting. If the marks do not align, so repeat the
adjustment procedure.

Used Belt

NOTE: Used belt which has been used for more than 2
hours.

Adjustment of the used timing belt.
Make the adjustment with engine cold.
Must be done with engine cold at least 8hr cool down.

a. A prerequisite of this operation is that the timing

belt timing has been checked. This means that the
crankshaft is at 1st cylinder TDC (2) and the
camshaft pulleys are fixed with special tool
J–43037.

014RW066

Rotate crankshaft clockwise only, if rotated too far,
do not turn back this will result in incorrect
tensioner setting.

b. Loosen fastening bolt (1) of the timing belt tension

roller. Apply counterclockwise tension to the timing
belt tension roller until the pointer is right at the right
edge of the mark (see diagram below). Tighten the
fastening bolt (1) of the timing belt tension roller.
