POINT
• Make sure that the teeth of the Timing Belt and the pulley are properly engaged.
• The standard for temporary fastening is where the Motor Unit can be moved by hand
and will not tilt when pulled. If this is either too loose or too tight, it will not provide the
proper tension to the belt.
CAUTION
If the Timing Belt is placed on the flange, correct tension will not be obtained during belt
tension adjustment.
Adjust the belt tension.
3.1 Adjusting the Timing Belt Tension
Set the belt so that it is level
with respect to the pulley
without it being placed on the
flange.
