1. Measure the camshaft journals with a micrometer. If the camshaft journals are not within specifications, replace the camshaft. The measurement should be 47.655 - 46.858 mm (1.8462 - 1.8448 inch). If the measurement is not within specifications the engine camshaft must be replaced.





2. Measure the camshaft runout using J7872.
1. Mount the camshaft in V-blocks between centers.
2. Use J7872 to check the intermediate camshaft journal.
3. If the runout exceeds specifications, the camshaft is bent and should be replaced. If the camshaft journals are more than 0.025 mm (0.0010 inch) out-of-round, then replace the engine camshaft.
