Measure the height (1) of the cam using a micrometer, and replace the
camshaft when the measured valve is less than the specified limit.
Specifications
| • | The height of the cam standard, interior is 35.156 mm (1.3841 in). |
| • | The height of the cam limit, interior is 35.124 mm (1.3828 in). |
| • | The height of the cam standard, exterior is 34.814 mm (1.3706 in). |
| • | The height of the cam limit, exterior is 34.789 mm (1.3696 in). |
Measuring the Camshaft Bend
Measure the bending of the camshaft using a dial gage, and replace it when the
measured value is over the specified limit.
Specification
The bending limit is 0.03 mm (0.0012 in).
Using a bore gage, measure the inner diameter of the cylinder head journal at
the 4 places--The clearance of journal is measured by the difference between
the outer diameter of camshaft journal and inner diameter of cylinder head journal
part (1).
Replace the camshaft or cylinder head, if necessary of which limit is over the
specified limit.
