7. Remove the setting pin that has been inserted into the

auto-tensioner.

8. Turn the crankshaft two turns clockwise to align the timing

marks.

9. Wait for at least five minutes, and then check that the

auto-tensioner pushrod extends within the standard value.

Standard value (A): 4.8

− 5.5 mm (0.19 − 0.22 inch)

10.If no, repeat the operation in steps (5) to (9) above.
11.Check again that the timing marks of each sprocket are

aligned.

.

>>B<< AUTO-TENSIONER INSTALLATION
1. While holding the auto-tensioner by hand, press the end of

the pushrod against a metal surface (such as the cylinder
block) with a force of 98

− 196 N (72 − 145 pound) and

measure how far the pushrod is pushed in.

Standard value: Within 1 mm (0.04 inch)
A: Length when no force is applied
B: Length when force is applied
A

− B: Amount pushed in

CAUTION

• Place the auto-tensioner perpendicular to the jaws of

the vice.

• If there is a plug at the base of the auto-tensioner, insert

a plain washer onto the end of the auto-tensioner to
protect the plug.

2. If it is not within the standard value, replace the

auto-tensioner.

3. Place two dolly blocks in a vice as shown in the illustration,

and then place the auto-tensioner in the vice.

CAUTION

Never compress the pushrod too fast, or the pushrod may
be damaged.
4. Slowly compress the pushrod of the auto-tensioner until pin

hole A in the pushrod is aligned with pin hole B in the
cylinder.

5. Insert the setting pin into the pin holes once they are

aligned.
NOTE: If replacing the auto-tensioner, the pin will already be
inserted into the pin holes of the new part.

CAUTION

Do not remove the setting pin from the auto-tensioner.
6. Install the auto-tensioner to the engine.
