4. Remove the tension spring from the timing
belt
tensioner
and the tension spring bracket, and remove the timing
belt tensioner.
CAUTION
When removing the timing belt, be sure not to bend
the belt sharply (that is, do not bend the belt into a
small radius). The cablecord contained in the timing
belt is extremely durable against tensile forces.
However, the cablecord is susceptible to breakage
when the belt is sharply bent. Bending reduces the
belt's overall strength.
5. Carefully remove the timing belt from its pulleys.
CAUTION
The timing belt
IIJ1JS1
be kept free of oil, grease, water
or other substances which may cause the belt to
deteriorate or swell.
6. Inspect the timing belt for deterioration, swelling, crack-
ing, and peeling or deformed teeth; replace the belt
if
it
is found to be faulty or after 1000 hours of operating
service. Refer to the pictures below.
7. Inspect the timing belt tensioner for abnormal noise
and/or damage at the belt contact point. If the timing
belt tensioner is excessively worn, replace it.
8. Remove the camshaft timing belt pulley.
NOTE: When removing the camshaft timing belt
pulley, insert a screwdriver between the spokes of
the pulley to prevent the camshaft rotating while
loosening the pulley's screw.
9. Remove the crankshaft timing belt pulley. 10. Remove the timing belt cover No.2.
