AUTO TENSIONER INSTALLATION

1.

Apply 98 – 196 N force to the push rod of the auto tensioner
by pressing it against a metal (cylinder block, etc.), and
measure the movement of the push rod.

Standard value:

Within 1 mm
A: Length when it is free (not pressed)
B: Length when it is pressed
A – B: Movement

2.

If it is out of the standard value, change the auto tensioner.

3.

Use a press or vice to gently compress the auto tensioner
push rod until pin hole A of the push rod and pin hole
B of the tensioner cylinder are aligned.

Caution
If the compression speed is too fast, the push rod
may become damaged, so be sure to carry out this
operation slowly.

4.

Once the holes are aligned, insert the set pin.

NOTE
When replacing the auto tensioner with a new part, the
pin will be in the auto tensioner.

5.

Install the auto tensioner to the engine.

TIMING BELT TENSION ADJUSTMENT

1.

After turning the crankshaft a 1/4 turn anti-clockwise, turn
it clockwise to the position where the timing marks are
aligned.

2.

Loosen the fixing bolt of the tensioner pulley and using the
special tool and a torque wrench, apply tension to the timing
belt; then tighten the fixing bolt at the specified torque.

Standard Value:

2.5 – 4.0 Nm [timing belt tension torque (reference
value)]

Caution
When tightening the fixing bolt, ensure that the
tensioner pulley shaft doesn’t rotate with the bolt.

3.

Take out the 2 mm Allen wrench from the auto tensioner.
At this time, check to be sure that 2 mm Allen wrench
can be pulled out easily.
Turn the crankshaft clockwise 2 turns, and after leaving
it in this position for 5 minutes or more, check again to
be sure that the auto tensioner 2 mm Allen wrench can
be pulled out or inserted easily.
