is found damaged, replace it with new one.
1. Stop the engine and remove the key.
2. Press on the spot indicated in the figure below to
measure the deflection.

Replacing the belt
1. Loosen the lock nut first and then fully loosen the
tension bolt.
2. Lift the tension pulley and remove the belt.
3. Fit the new belt instead as shown below.
4. Tighten the tension bolt until the tension spring end
comes in close contact with the engine body. Finally
tighten up the lock nut.
