C: INSPECTION
1. TIMING BELT
1) Check the timing belt teeth for breaks, cracks or
wear. If any fault is found, replace the timing belt.
2) Check the condition on the back surface of the
timing belt. If cracks are found, replace the timing
belt.
CAUTION:
• Be careful not to let oil, grease or coolant
contact the timing belt. Remove quickly and
thoroughly if this happens.
• Do not bend the timing belt sharply.
In radial diameter h:
60 mm (2.36 in) or more
2. AUTOMATIC BELT TENSION ADJUSTER
1) Visually check the oil seals for leaks, and rod
ends for abnormal wear and scratches. If neces-
sary, replace the automatic belt tension adjuster
assembly.
NOTE:
Slight traces of oil at the rod oil seal does not indi-
cate a problem.
2) Check that the adjuster rod does not move when
a pressure of 165 N (16.8 kgf, 37.1 lb) is applied to
it. This is to check adjuster rod stiffness.
3) If the adjuster rod is not stiff and moves freely
when applying 165 N (16.8 kgf, 37.1 lb), check it us-
ing the following procedures:
(1) Slowly press the adjuster rod down to the
end surface of cylinder. Repeat this operation
two to three times.
(2) With the adjuster rod moved all the way up,
apply a pressure of 165 N (16.8 kgf, 37.1 lb) to
it, and check the adjuster rod stiffness.
