12. Timing belt
• To prevent the timing belt from getting out of
position, put the alignment mark on the cam
pulley, the crankshaft pulley and the timing belt
before removing the timing belt.
w CAUTIONS:
1) Do not bend or twist the belt, otherwise its core
could be damaged. The belt should not be bent at
a radius
less than 30mm.
2) Do not allow oil or other chemica[ substances to
come in contact with the belt. They will shorten
the
belt life.
3) Do not attempt to pry or stretch the belt with a
screwdriver or any other tool during installation.
4) Store timing belt in a cool and dark place. Never
expose the
belt to direct sunlight or heat. ~
