The engine is hot immediately after stopping it. You may get burnt if you touch the
engine. Wait until each part cools down.

Stop the engine and keep the key of the starter switch in safe.

If belt tension is excessive, the bearings and
belt will be damaged earlier.
x
Replace the bolt if it has elongated and the
adjustment margin is lost.

Run the engine at high speed for 30 minutes
after the belt is replaced. Check and adjust belt
tension then.
1. Check
1) Push a point in the middle of the clank pulley and
alternator pulley at approximately 98 N (10 kg). The
belt tension is proper if the belt slacks by
approximately 7 to 9 mm.
2) Replace the belt if the belt has cracks.
2. Adjustment
1) Loosen the bolts (1) and (2).
2) Turn the adjust bolt to move the alternator (3) so that
the belt slackens by approximately 7 to 9 mm.
3) Tighten the bolts.
4) Replace the bolt if it has elongated and the adjustment
margin is lost.
