3. Screw in the special tool until it comes in contact

with the timing belt tensioner arm.

CAUTION

The special tool can be gradually installed at a
rate of a 30 degree turn per second. If it is
screwed in all at once, the timing belt tensioner
adjuster rod will not easily retract and the special
tool may bend.

CAUTION

For reinstallation of the valve timing belt, draw an
arrow indicating the rotating direction (clock-
wise) on the back of the belt using chalk.
6. After removal of the special tool, loosen the timing

belt tensioner pulley mounting bolt and remove
the valve timing belt.

<<B>> POWER STEERING OIL PUMP,
BRACKET AND RESERVOIR ASSEMBLY
REMOVAL

With the hose installed, remove the power steering
oil pump assembly from the bracket.
NOTE: Secure the removed power steering oil pump
assembly with cord or rope at a position where they
will not interfere with the removal of the balancer tim-
ing belt.

timing marks are aligned.

2. Install the balancer timing belt on the crankshaft

balancershaft drive sprocket and balancershaft
sprocket. There should be no slack on the tension
side.

3. Assemble and temporarily fix the centre of the

pulley of the balancer timing belt tensioner so that
it is at the top left from the centre of the
assembling bolt, and the pulley flange is at the
front-side of the engine.

4. Adjust the balancer timing belt tension.

>>B<< BALANCER TIMING BELT
TENSION ADJUSTMENT

CAUTION

When tightening the mounting bolts, ensure that
the tensioner does not rotate with the bolts.
Allowing it to rotate with the bolts can cause
excessive tension of the belt.

AC102691AB

Belt tension side

1. With your fingers, lift the balancer timing belt

tensioner in the direction of the arrow. Apply
pressure of 3.0

± 0.4 N⋅m to the balancer timing

belt. Tighten the assembling bolt to the standard
torque. Then, fix the balancer timing belt
tensioner.

Tightening torque: 19

± 3 N⋅m

3. Apply a pressure of approximately 100N at the

centre (arrow area) between the sprocket as
shown, then inspect whether the belt deflection is
within the standard value.

Standard value:

At adjustment: 5

− 7 mm

At replacement: 5

− 7 mm

4. If not within the standard value, adjust the belt

tension again.
