maximum value, the camshaft should be
replaced.

2. Check the maximum height of the cam of
intake/exhaust camshaft
(a). Measure the maximum height of the cam
of intake/exhaust camshaft with screw
micrometer.
• Replace the camshaft if the measured
value exceeds the limit value.

3. Check the intake/exhaust camshaft journal
