ADJUSTMENT OF BELT TENSION

Checks after Adjustment
• Turn the Timing Belt and check that all the Pulleys and grooves of the Belt fit securely.
• Each Belt should flex a little when the Belt is lightly pressed with a finger.
Reference
Since a given tension is applied by a tension spring to the Tension Lever that maintains the
tension of each timing belt, adjustment is completed by re-tightening the mounting screw
after it has been loosened.
